Microsoft deliverability

Hey Lori-Merchan

When you say Complain rate are you referring to users contacting you as they did receive an email or using another measure?

My first thoughts as a Braze user who works for Microsoft:
- If they are landing in inboxes and you are getting complaints, get an example of how they are rendering as Outlook can render like a hot mess, especially if you have no 'if mso' in your email code. Braze is pretty good at adding it if you use the drag and drop editor
- Outlook will also by default block all images, even from engaged senders if your domain is not approved internally such as an @Microsoft address, so if the email is reliant on images only, it may appear as nothing.
- If the emails are not landing at all be sure to check your subject and body copy as we tighten up the junk filter here on the daily, and if you are an external sender and look even 0.0001% fishy, you may not even land in the inbox. We get so many spam messages, marketing campaigns and random emails on the daily, it can sometimes be hard to crack through if you are not internal.

Happy to try and work this out.
