Microsoft Deliverability
I am currently ~35 days into IP warming. Since the start I've had issues with Microsoft. Even when sending ~137 emails a day to highly engaged openers I was marked as spam. Perhaps I moved to quickly...
Hi klfoulk16, sorry I missed this question earlier. I work in lifecycle marketing at Microsoft and 137 emails a day during warming would be no issue if you were ramping up carefully.
Microsoft does work on the premise of ' it's spam until proven otherwise' since security is our number one priority.
Looking at the error message and issue that is happening:
1. As TedScott mentioned, I would check if your IP provider or someone they work with is on a blocklist
You can put your own IP address into MX Tool Box to get a quick scan of whether it might be blacklisted.
Email Blacklist Check - IP Blacklist Check - See if your server is blacklisted
2. Does the content of your message, headings, bodies, CTAs sound spammy in any way? If the content sounds very promotional, Microsoft will junk it pretty quickly. You may be able to test this by sending a very neutral message to some of your trusted users or a test group. For example, anything suggesting to buy something would likely get junked but how-to or educational content is more likely to be okay.
:)
Thank you for the help! I think because Braze gave me the IP address that means that Braze is my IP provider? Do a lot of companies use Braze for messaging and another company for the IP typically?
I'm not only any block lists according to that tool. I've started sending to only about 70 people a day (and sending more consistently versus just on Thursday as I did previously). My emails are no longer block-bouncing and sometimes Microsoft gives me a "yellow" ranking. I think sending consistently each day of the week is important. My onboarding consultant had experience in the past with brands that could send one day a week, but I think that's not me yet.
2. Nothing Spammy. Typically my messages go to the primary inbox on gmail versus promotional. Put perhaps gmail isn't as strict.
I'm going to keep treading carefully with Microsoft and hopefully I'll be trusted eventually!
