Is there a way to be notified if e mail is undeliverable?

[Jr19]

I use square to invoice my customers but if I have an incorrect e mail I get no notice that it is undeliverable -

I have the same question and I can’t get anyone to answer this for me.

Hey @Powelletta,

It looks like there is no notification for undeliverable emails at this time.

I do see how that would be useful though so I'll be sure to pass this along to the Product Team!
