Preview and Test Your Campaign

This feature requires Author user level or higher.

Different email programs display your HTML email differently, so It's important to preview and test your campaign content before you send to your subscribers. Testing time decreases once you settle on a layout that works for you, but we recommend spending at least an hour to test new templates.

In this article, you'll learn how to preview your campaign in MailChimp's Preview mode, and how to send test emails. For more information on reviewing your content before sending, take a look at our  campaign testing tips.

Enter Preview Mode

The Preview and Test menu is available from the Design step of the Campaign Builder for most campaign types and gives you an idea of how your campaign will look in your subscribers' inboxes. Because each email client renders HTML differently, we strongly recommend that you do additional testing of your campaign.

If you're building a Plain-Text Campaign, you'll see Preview and Test on the Confirm step only.

To enter Preview mode, follow these steps.

  1. Navigate to the Design step of the Campaign Builder.
  2. Click the Preview and Test drop-down menu in the upper-right corner, and choose  Enter Preview Mode.

The panel shows the desktop preview of your campaign, and the right panel shows the mobile preview. You can click the Rotate link to change the orientation of the mobile preview.

The View header info option displays the campaign information, like the subject line and reply-to email address.

The View Live Merge Info option lets you test your merge tags by scrolling through and viewing each subscriber's information.

The Link Details pane displays the URL the link points to, a screenshot of what the website looks like, and tells you whether the URL is valid. MailChimp cannot preview links containing merge tags, anchors, or mail-to addresses in the Link Details pane.

If you need to change the URL the link points to, click Edit link under the URL in the Link Details screen.

To navigate between checked links, you can either use your mouse or use keyboard shortcuts. Use your left and right arrow keys to move up and down the list, and "e" to edit a link.

Customize Social Cards

Some social networks display a social card when your campaign is shared. This social card shows an image from your campaign along with some text to encourage viewers to click the link to your campaign's archive page.

Customizing Social Cards is especially useful when you want to control what is displayed when your campaign is  shared to Facebook or  integrated with Twitter.

When testing your campaign, you can choose the featured image and text as well as preview the social card. Select Social Cards from the Preview and Test drop-down menu on the Design or Confirm step of the Campaign Builder, and make any changes you want.

Send a Test Email

To send a test email from the Campaign Builder, follow these steps.

  1. Navigate to the Design step of the Campaign Builder.
  2. Click the Preview and Test drop-down menu, and choose Send a Test Email.
  3. Type the email address you want to send the test to. You also have the option to use the checkboxes to send to other users on your account.
