We have recently made the transition from Constant Contact to Microsoft Dynamics Marketing.
I have noticed that our open rates for our emails are significantly lower in Microsoft Dynamics. For example, a newsletter that would have had a 25% open rate in Constant Contact now receives a 15% open rate in Microsoft Dynamics.
We have followed best practices and standards referenced in the Microsoft Dynamic's Best practices for email marketing article. We have properly set up a sending domain and verified the DKIM records. We also let our email list know we would be transitioning to a new system, and to whitelist our sending domain.
Any idea what could be going on here?
