Hi. This is my first post here so hi to everyone! I need to send to a very large mailing list of commercial customers but dont want it to be flagged as spam before it even arrives so would like the sender address to be the same as the reply address. Im guessing that i can get in trouble in some way if people dont like being sent my email. I have a reseller account with lots of variations on some of my domains. Would it be safer to use that domain and mail server? All domains are with the same host and on the same server. Whats the best way to send the maximum amount of email?
