You see, when building a list, a lot of the emails you get are invalid, either because people who insert them had a typo, or because they put a fake one altogether.
And you're paying for all those extra emails with your hard earned more without ever knowing just how many are there.
If you have an email list that you think it's still not clean, and it will cause problems with your ISP, please contact me.
I will help you to clean up your email data with a few steps:
1. Remove duplicate emails
2. Remove bad domains
3. Remove invalid emails
4. Remove Role ID's (Admin, Sales, Support, etc. )
With a clean email list, you get better delivery rates, and help you reach your subscriber's inbox folder.
Note: Impossible to get 100% clean email list, but these step will give lots of benefits for you.
