Hello Jeremy,

Thank you for reaching out to us.

If your notifications sometimes work, and sometimes don't, the issue could be related to a timeout on the server. There's a way to force Amelia to check all appointments, and send out the notifications afterward, but please note that, if you have appointments that haven't received an email notification in the past, and you apply this workaround - all of them will receive an email about the booked appointment.

Please add the following cron job to your server, or in WP Crontrol plugin (depending on what you use to create cron jobs):

*/15 * * * * https://example.com/wp-admin/admin-ajax.php?action=wpamelia_api&call=/notifications/undelivered/send

But if this happened to only few customer you can cancel their appointment/ticket for event and approve it again. Perhaps this is the best solution. In general you should know that this is not issue with Amelia. Amelia is just a middle man and if notifications work for one customer they work for all of them since settings are set in general and there is no setting in Amelia that can prevent this not to be sent to some customers.

Let us know if that helps.

Best regards.
