Experts and email marketers agree that including event attendees in email warming lists requires careful consideration. Explicit permission and voluntary opt-in are essential before adding attendees. Starting with smaller, highly engaged segments and gradually increasing the volume to less engaged contacts is advisable. Employing double opt-in methods, segmenting the list based on engagement levels, and warming up the IP address beforehand are also important. Ensure compliance with regulations like GDPR and CAN-SPAM, and maintain list hygiene to optimize deliverability. Testing emails before sending is a recommended best practice.
