Sending newsletter to massive amount of users, how to prevent email server from being blocked?
I have a huge user base and I want to send a weekly newsletter to users who have opted in to receive newsletter emails. All of our emails are in compliance with the CAN-SPAM Act in the US. The newsletter would be mostly automated content with some news/updates.
I've noticed all of my competitors are sending daily or weekly emails and it makes me wonder how they are doing it without being flagged as spam by email black lists? How can I send a newsletter on a regular basis and ensure it doesn't get flagged or black listed? What should I consider before sending out a newsletter?
