Mailmodo is an email-marketing platform with strong support for AMP for Email: interactive in-inbox forms and surveys. Advanced Form Integration sends form submissions to Mailmodo as new contacts on a chosen mailing list.

What you’ll need

  • An active Mailmodo account.
  • A Mailmodo API Key (Settings → API Keys).
  • The Advanced Form Integration plugin installed and activated.

Get your Mailmodo API key

  1. Log in to your Mailmodo account.
  2. Go to Settings → API Keys.
  3. Create or copy an existing API Key.

Connect Mailmodo to AFI

  1. In WordPress, go to AFI → Settings.
  2. Enable Mailmodo and click Save Changes.
  3. Open the Mailmodo tab.
  4. Paste the API Key and click Save Changes.

Create the integration

  1. Go to AFI → Add New.
  2. Configure the trigger.
  3. In Action → Platform, select Mailmodo.
  4. In Task, choose Add Contact to List.
  5. Pick the Mailing List: AFI auto-loads your lists.

Tasks supported

Add Contact to List

Adds the form submitter as a contact on the chosen Mailmodo list. Re-submissions update the existing contact rather than creating duplicates.

Conditional logic example

Subscribe to your “Engaged readers” Mailmodo list only when the form’s engagement_signal hidden field is “high”. Mailmodo’s interactive AMP campaigns work best with engaged audiences. Other submitters go to a standard list via a separate integration.

Troubleshooting

Integration doesn’t fire

Open AFI → Log and find the most recent entry. The log shows the request payload sent to Mailmodo and the response received, usually pointing straight at the cause.

List dropdown empty

Your Mailmodo account must have at least one list. Create a list inside Mailmodo first, then refresh the AFI page.
