Fair - it's Gmail-only today. We've thought about generic IMAP, but it seems to have some technical gaps for how our email surface works. For instance, there's no reliable cross-provider way to pre-create drafts on a thread. So we haven't prioritized it just yet. We do plan to add Outlook support soon.
Again, great app - all the best for the future!
starting with indies and SV startups and education is less risky, but the real market outside startup culture is often overlooked by those who came up inside that culture
generic IMAP is not worth the time, first class integration with M365 is worth the time
OIDC flavor "Continue with Microsoft" should be right there beside Continue with Google / Github / Whatever, on every SaaS that wants business clients small enough to make "sign up online" decisions. By contrast, for consumer, Continue with Apple would be the equivalently overlooked OIDC option if you are targeting "wallet share" (a revenue model) instead of headcount (an ad model, for instance).
* Didn't look this up. Used to be. Doesn't matter if 50% or 90%, it's substantial, and point stands: don't overlook it.
