Hi @vincentczb,
I donât think this is a bug, as mentioned here:
"The form actions run when the form is submitted. You may set one or multiple actions for your form. They will run in sequence according to the order defined, except for the âRedirectâ action, which will run after all other actions. "
So if the âsave submissionâ action is added before the âemailâ action then the form should be submitted even if the email fails to send.
But if you did the above and the form entries are still not being saved, then that would indeed be a bug.
