How to Send SliceWP Data to MailRelay

MailRelay is a email marketing platform for managing subscribers and campaigns. Getting SliceWP data 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 SliceWP 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 SliceWP to MailRelay.

2. Pick your trigger

Select SliceWP as the form provider. AFI fires when an affiliate registers or a commission is recorded, giving you access to affiliate details, referral amounts, and commission data.

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 SliceWP field on the right. Common mappings include affiliate name, email, referral ID, commission amount, and status. You can also use smart tags like {{_submission_date}}.

5. Add conditions if needed

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

6. Save and test

Click Save Integration. Trigger a test event in SliceWP. 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 referrals. Pro adds custom field mapping. No per-referral fees on any plan.

Frequently asked questions

Which SliceWP events trigger the integration?

AFI fires when an affiliate registers or a commission is recorded. This covers new affiliate registrations, referral creations, and commission status changes.

Will adding this slow down my site?

No. AFI sends data to the destination after the affiliate event completes. Your site performance is not affected.

Can I send affiliate data to multiple platforms?

Yes. Create a separate integration for each destination, and every event flows to all of them simultaneously.
