Hey @Hector Sanchez56! Sorry for the trouble. If you're not receiving the incentive email, we have a troubleshooting guide on that here73. Also, please note that if you have double opt-in53 enabled on that landing page, subscribers will show up on your list as unconfirmed until they click the link in the incentive email (more info on that in this answer53).
If the issue persists after those troubleshooting steps, though, please feel free to reach out to our team at help@convertkit.com92 (or via the in-app messenger in your account) with a description of this issue, the email address(s) of example subscribers experiencing it, and the name of the landing page (as it is displayed on the forms page58 in your account). One of our Product Specialists will be able to help troubleshoot further! :)
