#3My private email server gets completly blocked on regular bases. They are blocking the whole ip-range of my provider. You get no response from them whatsoever. You have to fill out a form und wait a couple of days. You can however sign up for a 200$ whitelist... from a different company owned by guess who.

I would assume any provider that allows you to send email also allows a great deal of spam, so this might not be unwarranted. My provider is also frequently blacklisted, I just don't use it to send mail anymore.

#7Maybe Tutanota.com has a lot of outlook users reporting your marketing emails as spam. I generally do this if the unsubscribe route is too painful, or even if it takes too long to load.

What the original poster describes is anti-competitive behavior, for this reason alone the idea of blocking the whole IP range of a competing email service provider is very bad. Personally, I wouldn't use an email provider that blocks spam server-side without an option to turn this off because these filters often block legitimate mails and can cause all kinds of annoying problems.

#9This is just that last of many cases of MS Outlook acting in an intentional power abusive market distorting way.
I do not know about tutanota and if they are a bad actor in the email space. But I remember them having done funny things like banning the complete German Hetzner IP range because Hetzner didn't want to give them customers information without an curt order (which I guess Hetzner isn't allowed to do either iff the customer(s) in question is a private customer...).
Like consider Google banning all Azure hosted mail providers independent of their reputation and DMARK,DKIM,SPF etc. because MS keeps with the law and doesn't give Google private customer information, it's that ridiculous.

I worked for a company that sent travel deals newsletters everyday. Deliverability to (then) Hotmail was abysmal.
We then got the recommendation of a company (cannot remember their name) that could analyse our IPs and give recommendations. Naturally, the recommendations were the ones that you could find everywhere so they were not useful, but the company did have access to MSFT's score of our IPs, so we could know when we were close to being blacklisted and could take action/ramp down/etc. How did they have access to those internal IP scores? I don't know, but it seems totally fishy :).
For sure we spent 5k+ USD yearly in this service (which is a huge amount of money in a 3rd. world country), and "somehow" after paying our deliverability did improve, despite doing the same things as before, as the recommendations were not ingenious.
So yeah, e-mail deliverability is a mafia, for sure.
