I'm told a recent O365 update has blocked Constant Contact emails from landing in Outlook inboxes. My last campaign went from a 55% open rate to a 12% open rate. Tech support tells me they are aware of the issue but don't have a solution. This is an update on the O365/Outlook end that affects the ability of an email landing in the inbox. Some are getting through to Spam/Junk but most show up as delivered but never arrived. What is being done on this? If there is no solution in sight I'm going to need to move to a different ESP.
Hello @KenB05797 ,
Here are some general best practices for deliverability.
Deliverability can have a lot of variables, from elements on our side, on your side, on the recipient's side, and in their email system company's side. It's also a generally good idea to set up additional authentication for your emails - particularly self-authentication since you have your own domain.
If you'd like to learn more about safelisting, and what it entails:
If you're wanting more in-depth, specialized insight on your current deliverability, it'd be worth speaking with one of our Deliverability agents, like the chat agent you spoke with suggested.
This did not answer my question and a conversation with a Delivery Agent left me with the distinct impression there was nothing you could do to resolve the O365/Outlook Security issue. I'm exploring a different email client to replace Constant Contact.
