# Campaigns

> The Campaigns menu is where you design and send your newsletters. It shows your sent, unfinished and scheduled campaigns, it's where you start a new one, and it leads to your templates and images too.

The **Campaigns** menu is where you design and send your newsletters. It shows your sent, unfinished and scheduled campaigns, it's where you start a new one, and it leads to your templates and images too.

## The campaign list

Open **Campaigns** in the left menu. The list has three tabs, each with its count:

| Tab | What it shows |
|---|---|
| **Sent** | Campaigns that went out, newest first, with the number of recipients, the open and click rates and the CTOR (how many of the openers clicked). A campaign whose sending you stopped halfway also lands here, labelled **Canceled**. |
| **Drafts** | Campaigns not sent yet. Each card shows which step you're at (**Design email**, **Details**, **Schedule**). |
| **Outbox** | Scheduled campaigns and campaigns being sent right now, with their send time. |

![The Campaigns page on the Sent tab](https://docs.uptools.io/_astro/04-campaigns-list.DkcRayk3_Z200B72.webp)

Click the name of a sent campaign or **View report** to open its report. Reports are covered in the [Reports](https://docs.uptools.io/echo/user-guide/reports/) chapter.

Above the list you can filter:

- **All campaigns**: by folder. Use **+ Create folder** in that list to add a folder, and **Move to** to put the selected campaigns in one.
- **Type**: by campaign type.
- **Any date**: by date (the **Outbox** tab has no date filter).
- **Search by campaign name or subject**: by part of the name or the subject.

![The Drafts tab with two unfinished campaigns](https://docs.uptools.io/_astro/04-campaigns-drafts.0OwQplYz_1tclif.webp)

On a draft, **Overview** shows the email preview and the settings, and **Continue editing** takes you back to where you left off.

> **Good to know**
>
> - The filters also go into the browser's address bar, so you can bookmark a filtered list.
> - With a folder selected, the tab counts still include the campaigns of every folder.
> - Select several campaigns on the Sent tab and click **Download reports (…)** to get their numbers in one CSV file.

## Campaign types

When you start a new campaign, you choose its type first. You can't change it later.

| Type | What it's for |
|---|---|
| **Regular** | One email to the subscribers you select. Most newsletters are regular campaigns. |
| **A/B split** | You try one thing (subject line, sender, content or sending time) in two versions on part of your recipients, and the better version goes to everyone else. |
| **Auto resend** | After the first email, a second one goes to those who didn't open it or didn't click in it. |
| **Multivariate** | Like an A/B split, but you can test up to 3 things at once, with 2-4 versions each. |
| **RSS** | Not available yet: its card says **Coming later**. |

![The Choose campaign type page](https://docs.uptools.io/_astro/04-campaigns-types.1LON_IeR_2aEL6x.webp)

## How to create a campaign

1. On the **Campaigns** page, click **Create campaign**.
2. Pick the type and click **Create campaign** on its card. Echo creates the draft right away (named, for example, **Regular campaign Oct 22, 2026**) and opens the wizard.
3. The wizard has three steps, and its header always shows where you are:
   - **Design email**: choose a starting point and edit the email.
   - **Details**: name, subject, sender, recipients, language and tracking.
   - **Schedule**: send now or later.

The wizard saves every change by itself, and the header then shows **● Saved**. You can leave at any time with **×** in the top left corner: the campaign waits on the **Drafts** tab, and **Continue editing** takes you back to where you left off.

> **Good to know**
>
> - Users with the Administrator and Manager roles can create campaigns. A Viewer only sees sent campaigns and their reports.

## How to choose what the email starts from

On the **Design email** step you have three starting points.

1. **Start from scratch**: pick an editor and click **Choose** on its card.
   - **Drag & drop editor**: you build the email from blocks, with many layouts and styles.
   - **Simple editor**: you write as in a word processor, and the email's style comes from your brand styles.
   - **Custom HTML editor**: you code the email yourself.

   ![The Design email step with the three editors](https://docs.uptools.io/_astro/04-campaigns-design.B4Rnzg05_Z1rh3Co.webp)

2. **Template gallery**: the **Gallery** tab has ready-made designs by category (for example **Newsletters**, **Deals and offers**, **Events**), and the **My templates** tab has your own templates. **Preview** lets you look inside, and the **Choose** button starts from it.

   ![The Template gallery tab](https://docs.uptools.io/_astro/04-campaigns-gallery.DTuA4Mpg_Z21YUVO.webp)

3. **Recent emails**: you start from a copy of a sent campaign, a draft or an automation email. This is the quickest way when your newsletters keep the same structure month after month.

After you choose, the editor opens.

> **Good to know**
>
> - You can pick a template or a recent email only while the email has no content. Once you've edited it, create a new campaign instead.
> - If you switch to another editor later, the email starts over empty. Echo asks first, because the current content can't be restored.
>
> ![The Replace the email's content? question](https://docs.uptools.io/_astro/04-campaigns-replace.CRmk6S6b_1zbhG0.webp)

## How to edit the email in the Drag & drop editor

The editor has three columns: the blocks on the left, the email in the middle and the settings of the selected block on the right. With nothing selected, the right column shows **Email settings**: the email width, the font and the colours. Colours you leave empty come from your brand styles (**Brand colour**).

![The Drag & drop editor with a copy of the Pumpkin season email](https://docs.uptools.io/_astro/04-campaigns-editor.FndAp1sc_28zguk.webp)

1. Click a block in the list on the left, or drag it into the email where you want it. A clicked block goes below the selected block; with nothing selected, it goes to the end of the email, above the footer.
2. Click a block in the email. Its settings appear on the right, for example the label, link, alignment and colours of a button.
3. Edit the texts directly in the email.
4. When you're done, click **Done editing** in the bottom right corner. If a button has no link, Echo tells you so you can fix it.

![A selected button with its settings](https://docs.uptools.io/_astro/04-campaigns-block-settings.3XPV7h3A_27Ndht.webp)

**The blocks**

| Group | Blocks |
|---|---|
| **Saved blocks** | Your own saved blocks (see below). |
| **Navigation** | **Logo**, **Logo + Navigation**, **Logo + Social links** |
| **Hero** | **Standard hero**, **Title + image** |
| **Sections** | **Single section**, **2 columns**, **3 columns**, **Large + small column**, **Small + large column**. You can put other blocks in the columns; on mobile they stack. |
| **Elements** | **Title**, **Subtitle**, **Text**, **Image**, **Button**, **Divider**, **Spacer**, **Video**, **Links**, **Custom HTML** |
| **Content** | **Basic CTA**, **Image + content** |
| **Special** | **Accordion**, **Carousel**, **Countdown timer**, **App download**, **Survey**, **Quiz**, **Event (RSVP)** |
| **Social and sharing** | **Social links** |
| **Footer** | **Centered footer**, **Basic footer**, **Aligned footer**, **Footer + navigation** |

**The block toolbar**

A toolbar appears beside the selected block, to the right of the email. From top to bottom: drag, **Move up**, **Move down**, **Save block**, **Edit**, **Hide in email**, **Visibility**, **Duplicate** and **Delete**. When the block sits inside a column or another block, or there's no room beside the email, the toolbar appears above the block instead, in the same order from left to right.

![The toolbar of the selected block](https://docs.uptools.io/_astro/04-campaigns-block-toolbar.DhKeKS5__Z1EI7qX.webp)

- **Hide in email**: the block stays in the editor but isn't put in the email. Handy when you want to leave a part out for now.
- **Visibility**: choose who sees the block: **Everyone**, **Members of groups**, **Everyone except groups**, or a **Custom rule**. This way, for example, your VIP customers can get a different offer in the same email. Who sees a conditional block is decided when the email is sent.
- **Save block**: save the block under a name, and it will be under **Saved blocks** in any email later.

![The Save block template window](https://docs.uptools.io/_astro/04-campaigns-save-block.DJP_Nqk-_UoWSB.webp)

> **Good to know**
>
> - **Undo** and **Redo** are in the top left corner of the editor.
> - Use **Choose image** to pick an image from the file manager or to upload a new one there.
> - The company details, the unsubscribe text and the links of the footer come from **Default settings**, in the email's language. See the [Settings](https://docs.uptools.io/echo/user-guide/settings/) chapter.
> - Echo removes JavaScript, iframes and form elements from **Custom HTML** blocks.
> - **Accordion** and **Carousel** are interactive in Apple Mail, iOS Mail and Samsung Email; other email apps show the static version.
> - To delete a saved block, use the three-dot menu next to its name under **Saved blocks**. Emails that already use it don't change.

## How to add a survey, a quiz or an event to the email

With these three blocks, subscribers can answer right from the email with one click. An answer opens a confirmation page, and you see the results on the **Responses** tab of the campaign report (see the [Reports](https://docs.uptools.io/echo/user-guide/reports/) chapter).

**Survey**

1. Click **Survey** in the block list.
2. Type the question in **Question** and the possible answers in the **Answer** fields. **Add answer** adds one more, and **Move up** and **Move down** put them in order.
3. If you like, fill in **Thank-you text**. The person who answers sees it on the confirmation page.
4. In the **Answers** list, choose whether the buttons go one under the other or in one row.

![A survey in the email and its settings](https://docs.uptools.io/_astro/04-campaigns-survey.BPPY7lkT_Zfc7CL.webp)

**Quiz**

A quiz is built the same way, with two differences: under **Right answer** you mark the correct one, and in **Explanation (shown after answering)** you can add a short reason. Until a right answer is marked, the quiz isn't put in the email.

![A quiz with the right answer marked](https://docs.uptools.io/_astro/04-campaigns-quiz.N9J3WzW2_23W206.webp)

**Event (RSVP)**

1. Click **Event (RSVP)** in the block list.
2. Fill in **Title**, **Starts** and **Ends**. The times are in the workspace's time zone.
3. If needed, fill in **Location**, **Online link** and **Description**.
4. **Offer “Maybe”** gives three buttons (**Yes**, **Maybe**, **No**), and **Show “Add to calendar” links** adds Apple / Outlook, Google Calendar and Outlook.com calendar links below them.

![An event block with Yes, Maybe and No buttons and calendar links](https://docs.uptools.io/_astro/04-campaigns-event.y6nDsn4p_1RjamR.webp)

> **Good to know**
>
> - A question can have 2-6 answers, and one email can have at most 20 survey, quiz and event blocks in all.
> - Subscribers can change their answer to a survey or an event later; the last one counts. For a quiz, the first answer counts.
> - Personalization tags (such as `{$name}`) don't work in these blocks: the answer page would show them as typed.
> - An unfinished block (an empty question, no right answer marked, an event without times) isn't put in the email. The **Schedule** step warns you about it.

## How to write an email in the Simple editor

The Simple editor is a good choice when the email is mostly text, such as a personal message.

1. Type the email's title in **Title (optional)**.
2. Write the text in the field below. The formatting bar inserts bold, italic, links, lists, quotes, images, buttons, countdown timers, surveys, quizzes and events. You get the same by typing `/`.
3. In the **Style** panel on the left, set the font, colours, width and alignment.
4. **Show footer** puts your brand's footer at the bottom of the email, with company details, social links and the unsubscribe link.

![The Simple editor with a title and text](https://docs.uptools.io/_astro/04-campaigns-simple.CoZPbuWT_SNkJk.webp)

> **Good to know**
>
> - If you turn the footer off, a standard unsubscribe footer is still added when sending.
> - Use **Visibility** here too to show a paragraph only to certain groups.

## How to code the email yourself

The **Custom HTML editor** shows the preview on the left and the code on the right.

1. Type or paste the HTML code. The preview updates as you type, and **Desktop** and **Mobile** switch between views.
2. **Problems** lists unclosed tags, elements not allowed in emails and unknown personalization tags, with line numbers.
3. You can bring in a ready HTML email with **Import HTML (ZIP)**. The ZIP can be up to 10 MB, and its images go to the file manager.
4. **Format** tidies up the indentation of the code.

> **Good to know**
>
> - **Inline CSS before sending** writes the styles onto the elements, because many email apps don't read the style block.
> - **Edit plain text version** lets you write the version for email apps that show only text. Until you edit it, Echo makes it from the HTML.
> - If the email is larger than 102 KB, Gmail clips it. You get a warning about this.

## Personalization tags

With tags, each subscriber gets their own data in the email, such as their name. A tag looks like `{$fieldkey}`, for example `{$name}`. You find the keys in the **Tag** column on the **Fields** tab under **Subscribers** (see the [Subscribers](https://docs.uptools.io/echo/user-guide/subscribers/) chapter).

1. Next to the subject, and in the Simple and the HTML editor, click **Insert personalization**.
2. Pick the field. The tag goes where the cursor is.

![The Insert personalization menu next to the subject](https://docs.uptools.io/_astro/04-campaigns-personalization.L2zMsA-T_1UVlFw.webp)

If a subscriber's field is empty, you can give a default: `{$name|default('there')}`.

In the HTML editor, the menu also inserts these links:

| Tag | What it does |
|---|---|
| `{$unsubscribe}` | **Unsubscribe link** |
| `{$preferences}` | **Preference center link** |
| `{$webview}` | **View in browser link** |
| `{$forward}` | **Forward to a friend link** |

> **Good to know**
>
> - Next to the subject, the emoji button inserts an emoji.
> - The preview and the test email fill the tags with your own data, so you see your own name there.

## How to preview and test the email

The editor's top bar has these:

- **Preview**: the email as it appears in the inbox, in **Desktop** and **Mobile** view. In **A subscriber** view you can enter a subscriber's address and see which blocks they get.

  ![The Preview window](https://docs.uptools.io/_astro/04-campaigns-preview.BCsk4J07_Z23eT6g.webp)

- **Send a test**: enter up to 5 addresses separated by commas, then click **Send test**.

  ![The Send a test email window](https://docs.uptools.io/_astro/04-campaigns-test.BRtwoY4r_1Hb8tV.webp)

- **Versions**: Echo keeps earlier states of the email as versions. You can view any of them and bring it back with **Restore this version**. The current content then stays in the list as a version.
- **Actions**: **Save as template** saves the email to **My templates**, and **Remove content blocks** empties the email (you can undo this).

  ![The Actions menu](https://docs.uptools.io/_astro/04-campaigns-editor-actions.sHK3-OOb_1hlebf.webp)

> **Good to know**
>
> - Links in a test email don't track, and the unsubscribe link only leads to an explanation page, so a test doesn't affect your stats.
> - A workspace can send up to 50 test emails a day. Tests aren't sent to unsubscribed, bounced or suppressed addresses.

## How to fill in the campaign details

1. On the **Details** step, fill in **Campaign name**. Only you see it in the list.
2. Write the **Subject**. Next to it are **Insert personalization** and the emoji button.
3. **Preheader** is the short text shown after the subject in the inbox. It's worth filling in; otherwise the email app shows the first lines of the email.
4. Check **Sender name**, **Sender email** and **Reply-to email**. They come filled in from your workspace defaults.
5. Click **Select recipients** (see the next section).
6. Pick the **Language**. It's also the language of the unsubscribe page and the footer.
7. Decide whether to turn on **Track opens** and **Google Analytics (UTM tags)**. The UTM tags are added to every link in the email, and an empty **utm_campaign** becomes the campaign name.
8. Click **Continue**.

![The campaign details filled in, with the preview on the right](https://docs.uptools.io/_astro/04-campaigns-details.KMCvp2Fq_Za8qQi.webp)

The email preview is on the right. From here you can also send a test, go back with **Edit content** and edit the plain text version.

> **Good to know**
>
> - The sender must be an address on a verified sending domain. If its domain isn't verified, Echo warns you and the campaign can't be scheduled. Domains are covered in the [Settings](https://docs.uptools.io/echo/user-guide/settings/) chapter.
> - Without open tracking, the report has no open rate, and resending to non-openers isn't available.

## How to select the recipients

1. On the **Details** step, click **Select recipients**.
2. In the **Basic** view, tick who gets it:
   - **All active subscribers**,
   - one or more segments under **Segments**,
   - one or more groups under **Groups**.
3. To leave people out, click **Exclude** at the end of their row. Members of an excluded group or segment don't get the email even if they're in a selected list too.
4. **Recipients selected:** at the bottom of the window shows how many subscribers get it.
5. Click **Select**.

![The Select recipients window with one group and one excluded segment](https://docs.uptools.io/_astro/04-campaigns-recipients.C9LQvIko_Z28NezE.webp)

If you need a one-off filter without saving it, switch to **Advanced** and set the conditions the same way as when you filter subscribers. The conditions are described in the [Groups and segments](https://docs.uptools.io/echo/user-guide/groups-segments/) chapter.

> **Good to know**
>
> - Campaigns go only to **Active** subscribers, and someone in several selected lists still gets the email once.
> - The recipients are settled when sending starts. Anyone who joins a selected group before then gets it too.
> - If you start the campaign with **Create campaign** on a group or segment page, that group or segment is already selected.

## How to send or schedule the campaign

On the **Schedule** step, the campaign summary and the email preview are on the right.

1. Choose when it goes:
   - **Send now**: the campaign goes out right away.
   - **Send later**: set the **Date**, **Hour**, **Minute** and **Time zone**. Minutes go in 15-minute steps.
   - **Based on timezones**: each subscriber gets the email at the chosen time in their own time zone; those without a known time zone get it by your account's time zone.
2. Check the summary: subject, sender, preheader, recipients and send time.
3. Click **Schedule** in the bottom right corner, or **Send** when sending now. For an immediate send, Echo asks once more and tells you how many subscribers it goes to.

![The Schedule step with Send later](https://docs.uptools.io/_astro/04-campaigns-schedule.CPGUlRNb_ZN1XmX.webp)

**If something is missing**

If the campaign can't be sent yet, a **Fix these before sending:** list appears at the top of the page, with a **Fix** link on each line that takes you where you can fix it. Examples: a missing subject, an empty email, no unsubscribe link, a sender that isn't verified, no recipients, or a company name or postal address missing in **Default settings**.

The **Check these before sending (you can still send):** list only warns you, for example about an unfinished countdown or survey.

> **Good to know**
>
> - **Based on timezones** is only available for regular campaigns, and it has to be scheduled at least 24 hours ahead.
> - A scheduled campaign goes to the **Outbox** tab. Until it starts, **Cancel** puts it back in your drafts so you can change it.

## What happens after sending

- While it's sending, the campaign is on the **Outbox** tab, and its card shows the progress (for example **Sending… 1,200 of 3,500**). The list refreshes by itself.
- When it's done, the campaign moves to the **Sent** tab and its report opens. Opens and clicks keep coming in over the following days.
- You get a notification under the bell icon in the header when the sending finishes, and an email too if you asked for one in the settings.
- The content of a sent campaign can't be changed any more. To send a corrected version, copy it to your drafts.
- If sending gets stuck, the card shows why. If sending is paused (for example by the email provider), you can continue with **Resume sending** once the problem is fixed.

Reports are described in detail in the [Reports](https://docs.uptools.io/echo/user-guide/reports/) chapter.

## How to run an A/B split test

An example: the **Nyári öntözés A/B teszt** campaign tried two subject lines on the **Hírlevél HU** group. 20% of the recipients got version A and another 20% version B, and after 4 hours version B, which got more opens, went to everyone else.

1. Create an **A/B split** campaign and design the email like a regular one. This is version A.
2. At the bottom of the **Details** step, on the **A/B test** card, choose **What would you like to test?**: **Subject line**, **Sender**, **Content** or **Sending time**.
3. Set up version B: for example, enter the other subject in **Subject line of version B**. When testing content, version B starts as a copy of A and you edit it separately.

   ![The A/B test card with subject line B](https://docs.uptools.io/_astro/04-campaigns-ab-versions.ByiJweZA_14UQyH.webp)

4. On the **Schedule** step, set these on the **Test settings** card:
   - **Test group size per version**: the share of recipients who get each version (5-25%).
   - **Choose the winner by**: **Opens** or **Clicks**.
   - **Test duration**: in hours or days, up to 168 hours or 30 days.
5. Schedule or send the campaign.

![The Test settings card](https://docs.uptools.io/_astro/04-campaigns-ab-settings.C-S4ydOE_Z2bMtrs.webp)

During the test, the campaign is on the **Outbox** tab with the **Waiting for winner** label. When the time is up, Echo picks the version with the better rate and sends it to the rest of the recipients.

**Multivariate test**

A **Multivariate** campaign works the same way, but you can test up to 3 things at once, with 2-4 versions each and at most 8 combinations in all. The test group can be 10-50% of the recipients per combination.

> **Good to know**
>
> - With **Run A/B test on the entire list**, every recipient gets one of the versions and there's no winner. A sending time test always works this way.
> - A test needs at least 4 recipients, and at least one per combination.
> - If the winner can't be picked automatically, you can choose it yourself on the report's A/B split tab.

## How to give non-openers a second chance

There are two ways.

**An Auto resend campaign**

On the **Schedule** step, set these on the **Auto resend settings** card:

1. **What changes in the second email?**: only the **Subject line**, **Subject line and a personal message**, or **Subject line and content**.
2. **Who gets it?**: **Subscribers who didn't open the first email** or **Subscribers who didn't click the first email**.
3. **When?**: **The next day at the same time** or **At a specific time**, at least 24 hours after the first email.

**A resend from a sent campaign**

On the **Sent** tab, choose **Resend to non openers** or **Resend to new subscribers** in the campaign's three-dot menu. Echo creates a new draft with a copy of the email, and of its recipients only those who didn't open the original, or didn't get it at all, receive it. You edit and schedule the draft like any other.

> **Good to know**
>
> - Resending to non-openers needs **Track opens** to have been on for the original campaign.
> - A resend can't be resent to new subscribers again. Resend the original campaign instead.

## How to copy, rename, cancel or delete a campaign

Each campaign card ends with a three-dot menu. What it offers depends on the tab.

![The menu of a sent campaign](https://docs.uptools.io/_astro/04-campaigns-card-menu.BfdpOVZV_heGQy.webp)

| Menu item | Where | What it does |
|---|---|---|
| **Rename** | every tab | Gives the campaign a new name. Recipients don't see it. |
| **Duplicate** | **Drafts** | Makes a copy of the draft. |
| **Copy to drafts** | **Sent** | Makes a new draft from the sent campaign with the same email and settings. |
| **Resend to non openers** / **Resend to new subscribers** | **Sent** | See the previous section. |
| **Download report** / **Print report** | **Sent**, **Outbox** | The campaign's numbers as a CSV file or in a printable view. |
| **Cancel** | **Outbox** | A scheduled campaign goes back to your drafts. A campaign being sent stops: those who haven't got it yet won't get it. |
| **Delete** | **Sent**, **Drafts** | Deletes the campaign for good, and for a sent campaign its report too. |

![Confirming the cancel of a campaign](https://docs.uptools.io/_astro/04-campaigns-cancel.WEIaWNni_1TECck.webp)

> **Good to know**
>
> - A campaign sent in the last 30 days can't be deleted, so the links in its emails keep working. A campaign being sent can't be deleted either.
> - If a segment's filter refers to the campaign (for example "opened this campaign"), the campaign is kept.
> - You can delete several campaigns at once: select them and click **Delete (…)**. What can't be deleted is kept, and Echo tells you why.

## How to use templates

A template is a reusable email design. **My templates** in the left menu shows your own.

![The My templates page](https://docs.uptools.io/_astro/04-campaigns-templates.DvBHe2gR_24rqhX.webp)

**Save a template from an email**

1. In the editor, click **Actions**, then **Save as template**.
2. Fill in **Template name** and save. The template goes to **My templates**.

**Create a new template**

1. On the **My templates** page, click **New template**.
2. Fill in **Template name** and click **Continue**.
3. Choose a starting point the same way as for a campaign: **Start from scratch**, **Template gallery** or **Recent emails**.
4. Edit the email, then click **Save template**.

![The New template page with a name filled in](https://docs.uptools.io/_astro/04-campaigns-template-new.CBsPQByp_Z1QpE6l.webp)

**Use a template**

In the template card's three-dot menu, choose **Use in a campaign**. Echo creates a regular campaign with the template's name and content and opens the editor. When you start a new campaign, you can also pick it on the **My templates** sub-tab of the **Template gallery** tab.

![The menu of a template](https://docs.uptools.io/_astro/04-campaigns-template-menu.F07v9YaD_1ii7Lb.webp)

> **Good to know**
>
> - A campaign made from a template gets its own copy. If you change or delete the template later, the campaigns don't change.
> - In the menu you can also edit, rename, duplicate or delete the template.

## How to manage your images in the File manager

**File manager** holds the images and PDF files you use in your emails. The same file manager opens in the editor when you choose an image.

![The File manager with its folders](https://docs.uptools.io/_astro/04-campaigns-files.CRhvO4a8_Z1aHnTs.webp)

1. To upload, click **My device** under **Import from** and choose the files. You can upload several at once.
2. To bring in an image from the web, click **URL**, paste its address and click **Import**.
3. Under **Folders**, use **New folder** to organise your files. Move the selected files into a folder with **Move to**.
4. Under **Files**, filter between **Images** and **Files** (PDF); at the top you can search, sort and switch between **Grid** and **List** view.

> **Good to know**
>
> - Accepted formats: PNG, JPG, GIF, WebP and PDF. An image can be up to 5 MB, a PDF up to 10 MB.
> - When you upload, Echo removes hidden metadata from images (such as camera details).
> - A deleted file can't be restored, and emails already sent show a broken image in its place. Deleting a folder keeps the files in it.

## FAQ

**I sent a campaign with a wrong link. Can I fix it?**
A sent email can't be changed. Use **Copy to drafts** in the three-dot menu to make a corrected copy, and if needed, send it to the recipients with a short correction.

**Why can't I schedule my campaign?**
The **Fix these before sending:** list at the top of the **Schedule** step shows what's missing, and the **Fix** link takes you there. Common causes are a sending domain that isn't verified and a company name or postal address missing in **Default settings**.

**Can I change a campaign that's already scheduled?**
Yes. On the **Outbox** tab, choose **Cancel** in the campaign's menu. The campaign goes back to your drafts, where you can change it and schedule it again.

**How many recipients will the campaign go to?**
You see the number under **Recipients** on the **Details** step and at the bottom of the **Select recipients** window. The final list is settled when sending starts, and only **Active** subscribers get it.

**Why can't I delete a sent campaign?**
A campaign sent in the last 30 days can't be deleted, so the links in its emails keep working. After 30 days you can delete it. It's also kept if a segment's filter refers to it.
