I'm using Mailwizz application (licensed version) to send bulk emails. As for now I can send 50k emails per day. Now my business is being high and I'm supposed to send more than 100k emails per day. I tried with all codes to increase my sending per minute/hour. No one...
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like email@example.com.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
