Publish a Social Post When You Send an Email

Automatically post to Facebook, Instagram, and Twitter when you send an email, so you can coordinate your marketing efforts and save time. Include content from your email campaign or website, or share an image to promote your brand to your social followers.

In this article, you'll learn how to add a social post to your email.

Before you start

Here are some things to know before you begin this process.

Add a social post to your email

In the email builder, you'll choose your social channels and add content for each post individually. Facebook and Twitter posts require text, while Instagram posts require an image.

To add a social post to your email, follow these steps.

  1. Navigate to the Campaigns page of your account.
  2. Click the draft email campaign you want to work with.
  3. Navigate to the Add A Social Post To Your Campaign section of the email builder.
  4. Toggle the sliders to choose your channels. Then, click the drop-down menu to choose a specific page or profile.
  5. In the field provided, edit the message you want to include with your post.
    Here are some things to consider when you add your text.
    • For Facebook and Twitter posts, we’ll pull in your subject line and campaign *|URL|* merge tag by default. Other merge tags in subjects lines won’t display correctly, so make sure to remove them from your auto-post.
    • Facebook posts can include up to 500 characters. Twitter posts can include up to 280 characters.
    • Instagram posts can include up to 2,200 characters. We recommend you not add URLs to Instagram posts, as it’s not possible to click or copy a URL in an Instagram caption.
  6. Click Add Images to choose images for your post. If you want a Social Card to display with your Facebook or Twitter post, skip this step.
    Here are some things to consider when you choose your image.
    • You can add up to 4 images for Twitter and Facebook posts, and 1 image for an Instagram post.
    • Animated GIFs work for Twitter posts only and cannot be posted with any other image. Facebook and Instagram posts will display animated GIFs as static images.
    • For Twitter, we recommend you choose a file smaller than 5MB.
    • For Facebook, we recommend you choose a file smaller than 4MB. PNG files larger than 1MB may display as pixelated.
    • For Instagram, we recommend you choose a file smaller than 8MB. Your image size must be at least 150x150px with an aspect ratio of 4:5 to 1:91:1.
  7. Click Save Message.

Nice job! When you send your email, we’ll automatically publish your social posts.

Next steps

After you send your email with your social post included, follow its performance in Facebook and Instagram in the social post report. You’ll see how many people have viewed your post, how many likes and comments your post has received, and more.

About Social Post Reports


  • My campaign didn't publish my posts.
    Make sure the integration is set up correctly on the Integrations page. If your failed post included your campaign URL, you can copy the campaign page URL for your sent campaign, then send a social post.
  • My social account isn't an option.
    Navigate to the Integrations page and expand the Twitter or Facebook integration options. Make sure the account you want to post to has been integrated with your Mailchimp account or the specific audience that will receive your campaign.
  • I need to cancel my post.
    You can revoke Mailchimp’s access in your Twitter or Facebook account, which may prevent the post from publishing. If the post has already published, delete the post directly from your Twitter, Facebook, or Instagram account.
