How to Send WP User Frontend Data to MailRelay

MailRelay is a email marketing platform for managing subscribers and campaigns. Getting WP User Frontend submission into MailRelay does not require external tools. Advanced Form Integration handles it natively, and this guide covers every step.

Skip the automation middleman

Rather than routing data through a third-party cloud, AFI sends it directly from your WordPress server to email marketing. No task meter, no monthly bill.

What you will need

• A WordPress site with WP User Frontend installed and configured.
• A MailRelay account.
• The Advanced Form Integration plugin (free from WordPress.org).

Connect MailRelay to AFI

1. Log in to your MailRelay account.
2. Go to Settings → API and copy your API Key.
3. In WordPress, go to AFI → Settings → MailRelay.
4. Paste the API Key and your account name, then click Save.

Setting up the integration

1. Create a new integration

Go to AFI → Add New. Name it WP User Frontend to MailRelay.

2. Pick your trigger

Select WP User Frontend as the form provider. AFI fires when a post is submitted or a form is completed, giving you access to author name, email, post title, post content, and custom field values.

3. Select MailRelay as the destination

Choose MailRelay from the platform dropdown and pick Add Subscriber. This adds a subscriber to a MailRelay list.

4. Map fields

Match each MailRelay field on the left to the corresponding WP User Frontend field on the right. Common mappings include author name, email, post title, post content, and custom field values. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

Only want to send certain records? Set up a conditional rule based on any field value.

6. Save and test

Click Save Integration. Trigger a test event in WP User Frontend. Check MailRelay to confirm the data arrived. If anything looks wrong, open AFI → Log to see the exact request and response.

Free vs Pro

The free version maps email and name to MailRelay with unlimited records. Pro adds custom field mapping. No per-record fees on any plan.
