Hi

I own around 50 aged Gmail accounts. Let’s say I want to send 1 email from each account to 50 different addresses. I have an SMTP program that can do this with one click (1 Gmail account sends 1 email), so I don’t have to do everything manually one by one. Does this hurt the reputation in any way, or is it basically the same as sending them manually one by one?
