One of our clients didn’t pass the vetting process of sendgrid. Is there any way to get app users confirmed without sendgrid?
May I know your worrying about token expiration when click the link from confirmation email?
If yes then, you can create new page & new database table in bubble app.
Create new thing for the table linked with the user. And pass this unique ID into the sending email.
You can validate your self on page load action and show the status of user is valid or not.
