Error sending emails

Hello there!

I’m having some problems sending emails:
YT VIDEO SHOWING THE ERROR

Does anyone know what can be due?
Thank you very much for your help :blush:

What plan are you on for this app?

Enterprise! :blush:

So the email does not get sent at all after the error? There was a problem with that like months ago, but I think it was fixed.

Please submit a ticket if it persists.
