Before starting the warm-up process, you should prepare your subscriber list.
Sending emails to your subscribers first you should do these things which are:
- Update your authentication records like SPF/SenderID and DKIM/DomainKeys.
- Validate your current mailing list. Subscribers should be active, check for soft and hard bounces.
In your first week, test your limited volume of sends, as you are a new sender and have a large volume of sends just deliver a small number of messages every day.
If there is no issue during week one with deliverability, then add more recipients. By selecting your active subscriber you can double the volume of sends.
You can double your sending volume every three to four days until you reach your maximum daily volume.
If any error occurs, pause your sending or reduce the volume of sends. Stop sending to the subscriber where the issues are occurring and only resume sending after you have troubleshot the issue.
