Why add MailAdx to Beehiiv?
How to integrate MailAdx with Beehiiv
- 1
Create a free MailAdx publisher account
Sign up at mailadx.com/signup. Account review takes up to 24 hours. No credit card required.
- 2
Set up an ad placement in the Publisher Portal
In the MailAdx Publisher Portal, go to Ad Units and create a new placement. Set your floor CPM, format (banner or native), and any category block rules. Copy the generated ad tag.
- 3
Add the email-hash merge field to your Beehiiv template
In Beehiiv, the subscriber email hash variable is {{subscriber.email_md5}} or use SHA-256 if available in your Beehiiv plan. Add this to your template so MailAdx can use it for frequency capping and targeting.
- 4
Paste the MailAdx ad tag into your Beehiiv template
Copy the ad tag from Dashboard → Ad Units. In your Beehiiv editor, switch to HTML mode and paste the tag where you want the ad to appear. The tag is a standard HTML image wrapped in a link — it works in Beehiiv's drag-and-drop editor via the custom HTML block.
- 5
Send a test email and verify
Send a test send to yourself. Open the email and confirm the ad loads. Check your MailAdx Publisher Portal — you should see one impression. Once verified, you're live.

<!-- Replace {{EMAIL_SHA256}} with your ESP's email hash merge tag -->Beehiiv + MailAdx: common questions
Does MailAdx replace Beehiiv's built-in ad network?
MailAdx can replace or supplement Beehiiv's ad network. Many publishers use MailAdx as their primary monetisation layer (direct-sold + programmatic) and either disable Beehiiv's network or keep it as a secondary fill source via OpenRTB.
Can I use MailAdx while keeping my Beehiiv subscription?
Yes. MailAdx is a separate ad serving layer that works alongside your Beehiiv subscription. You don't need to change your ESP or migrate anything.
What Beehiiv email hash format does MailAdx require?
MailAdx accepts SHA-256 hashed email addresses for optimal targeting and frequency capping. MD5 is also supported as a fallback. The merge field format depends on your Beehiiv plan — check Beehiiv's documentation for the correct variable syntax.
