A. Ensure the spam complaint rate is between 1% and 3% B. Purchase lists from companies that guarantee users have opted in C. Authenticate email to distinguish it from spammers D. Purge old or inactive email addresses E. Encourage subscribers to add the company s sending domain to their address books
There are always different things that can affect the deliverability of the email. The first is letter C. The email being used to send messages should be authenticated so that it will be distinguished from all the other spam emails that are available. The next thing to do is to remove the different email addresses that are inactive or are false.
Sending emails to these email addresses can hurt the deliverability rates of the email greatly. Lastly, E can also be done by the subscribers to ensure that the emails will be received in the inbox and will not be labeled as spam by the email service provider. By doing these things, the spam rating of the company will be lessened and emails will be delivered without a lot of issues.
