When someone comments a keyword on your Facebook post or messages your Page, Zaprep replies publicly, opens a private Messenger conversation, delivers your link or offer, and asks for their email — automatically.

Facebook lead generation with Messenger automation turns organic engagement on your Facebook Page into contacts you own. When someone comments a keyword on a post or sends your Page a message, an automation replies instantly in Messenger, delivers what they asked for, and collects their email address inside the same conversation.
Example flow
A local fitness studio promoting a free class pass on its Facebook Page.
The post says: “Comment PASS and we’ll send you a free class pass in Messenger.”
Meta sends the comment to Zaprep through its webhooks in real time. Zaprep matches the keyword on that post.
Zaprep replies to the comment publicly (“Sent! Check your messages 📩”) and sends the commenter a private Messenger message — even if they have never messaged your Page before.
The Messenger message asks where to send the pass. The Ask Email step checks the address format and saves it to your Contacts.
Zaprep sends the booking link as a button. Links are shortened and tracked, so you can see how many people clicked.
The numbers Zaprep shows you for every campaign.
