We plan on sending out thousands of emails one day a month to our companies contacts. Were are concerned that we might become blacklisted because of this, should we be concerned?
Does an ISP (AT&T) monitor mail flow and they might notice an increase and decide we are spammers, while we are not?
I thought of also creating a new email alias instead of using our primary mail domain name to send out these emails, so instead of using our primary mail.mydomian.com, I would use "monthlymail.mydomain.com" but even if I use that wouldnt it still be linked to the same IP address as the primary mail email domain name and then be blocked as well?
Any suggestions would be very helpful. Thanks!
