How It Works

Automatically generates personalized email content for event attendees using AI, then queues it for review before sending. Perfect for marketers who want to scale personalized event follow-up campaigns without manually writing each email.

1

Identify event attendees who need follow-up

The system pulls your event attendee list and identifies people who are ready to receive your next follow-up email based on your timing settings.

2

Gather attendee information and preferences

Collects relevant details about each attendee from your database, including their interests, company info, and engagement history to personalize the content.

3

Generate personalized email content with AI

AI creates customized email content for each attendee based on their profile and the specific event they attended, ensuring relevant and engaging messaging.

4

Validate content quality and format

The system checks each generated email for proper formatting, removes any unwanted HTML, and ensures the content meets your quality standards.

Queue emails for manual review

All generated emails are added to a review spreadsheet where your team can approve, edit, or reject content before it goes out to attendees.

6

Alert team of any issues

If content generation fails or needs attention, your team receives instant notifications so nothing falls through the cracks.
