Hey fellow community members!

I just wanted to check if you've noticed huge differences in the open rate per domain? Examples of a few campaigns we've sent:

Campaign 1
gmail.com 35%
hotmail.com 5%
online.no 41%
live.no 6%
yahoo.no 31%

Campaign 2
gmail.com 42%
hotmail.com 7%
live.dk 5,923 7%
mail.dk 20%
yahoo.dk 29%

As you can see the open rate for hotmail.com/live is very low, a trend that we see accross countries. Are any of you experiencing the same?

BR, Sandra
@Sandra Nota Frustratingly, this is a common observation right now with Microsoft recipient domains (hotmail, msn, live, outlook) and we are hearing a lot of folks in the industry with similar metrics/issues across different sending platforms.

We noticed that after Microsoft merged the O365 and Hotmail systems (a little while back) that the filtering on new/bulk sender IPs has become a lot harsher and much harder to mitigate in a timely manner. It can take weeks/months to start to pushing through the filtering and that appears to be by design from Microsoft.

We are noticing though, that smaller transactional/triggered volume sends tends to have higher success rates with reputation, inboxing and open rates earlier on.
Hi @Brian Curry Thanks for your comment. We've seen as well that transactional emails do have a good open rate on the outlook domains. It's very frustrating though. We had a good open rate on these domains for a few months, but now they dropped again.
