Question
Which "email invalid cause" should be a solid "delete" in any list?
I'm cleaning up my database and I'm going through my bounces. I have about 1800+ leads on this leads which a variety of email invalid causes. The biggest chunk of which is are labeled:
- 550 [internal] [oob] the recipient is invalid (about 800+)
- 550 #5.1.0 Address rejected (140+)
- 554 5.4.7 [internal] exceeded max time without delivery (180+)
Do you recommend that we delete these or does it warrant further investigation?
Also, are the invalid causes that are automatic deletes for you? Thank you!
