In investigating the emails we have that are Invalid, I discovered that some of them were not delivering not because the email address was wrong, but because there were capital letters in the email and the address was case sensitive.
Has anybody else run into this issue? Is there any way around it/a way to prevent emails from not being delivered due to issues like that?
Email we sent it to: firstname.lastname@example.org - BOUNCED
Email we updated it to: John.Smith@xyzcompany.com - DELIVERED!
Help would be much appreciated.
