Now that we know what deliverability is and how it differs from email delivery, it’s time to understand which factors influence this metric. Stay tuned!
Authentication
Since authentication is a more technical part of the process, most people leave this step to the email service itself.
Several authentications need to be azerbaijan phone number resource done on a mandatory basis , as a way of informing your recipient that you are who you say you are.

This method authenticates the identity of the email server sending the message and the email address responsible for sending the message.
DMARC
Domain -Based Message Authentication, Reporting and Conformance (DMARC) is based on SPF and DKIM. Its function is to monitor the behavior of emails .
