Opt-Ins Settings
Opt-In Settings allow you to connect AffiliatePress with supported email marketing services. Once connected, new subscribers referred by affiliates can be automatically added to your selected email marketing platform.
Whether you’re using opt-in forms for lead generation or email marketing automation, from here you can ensure affiliate referrals are properly tracked and linked.
Head over to AffiliatePress → Settings → Opt-Ins to configure AWeber, Mailchimp, MailerLite and Omnisend.

Overview
AffiliatePress integrates with multiple email marketing providers. So, you can connect with your preferred service using its API key or Authorization Code.
When enabled, AffiliatePress can:
- Detect when a form is submitted (via supported platforms).
- Capture affiliate referral data tied to that user.
- Sync this information with your email marketing list.
- Attribute the opt-in action to the correct affiliate.
This is useful for list building, newsletter campaigns and automated funnels where affiliate referrals need to be credited even if the conversion happens later.
Note: Before connecting an email marketing service, make sure you have a valid API key from your provider.
