I'd be pissed off if I were an Outlook user - it's a shame that big tech get treated as the "gold standard" - I get that spam prevention is important but it shouldn't hurt your business. Their support is below standards. I wonder how many opportunities Outlook businesses lose because they don't receive certain emails.

That being said, email as a whole could do with being replaced with a more robust solution to make it more versatile and offer other spam prevention techniques.

If you give people free web services they're going to use it for spam, porn, file sharing or crypto mining. If even their most basic tier only cost a few quid a year, it would probably stop spam usage by 99%

Are you saying this does not apply for free Gmail or Outlook as well? Because those should be then blocked too.

Well, computers are tough. It takes ~31 days to update a database, right?

A database? No, that's instant. But when you have dozens of databases, each owned by a different company, and they feed off each other perhaps once a day, then you can end up with a long time before all your data is deleted.

And that’s their problem, not mine. If they structure their email campaigns such that it takes a long time to update every database, that’s a design choice on their side. When that design choice means they effectively ignore my unsubscribe, well, I don’t see why that should receive any sympathy.

This 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…

i installed MIAB like 3 years ago. had this exact same problem with outlook at the time. did the same and never have had any more problems. last year i helped someone install miab and somehow neither gmail nor outlook nor any "major" provider logged them as spam from the get go. i was truly impressed and surprised. i have heard war stories about people self hosting email and having problems. sure 3-5-10 years ago tha…

Just keep in mind that you need working reverse DNS record and not all cheap provides support it. Also cheaper hosting solutions usually have worse IP reputation.

> They are blocking the whole ip-range of my provider. That's not necessarily unreasonable, depending on which provider that is. Sites like Wikipedia also block entire ranges to prevent spam. Unfortunately sometimes people do get caught up in that (as I did last year).

Didn’t the Wikipedia one just block anonymous contributions from some ip range? As in, you could still sign up, login and contribute?

No; was blocked even when logged in. Had to create a ticket to unblock (IP range had been re-assigned, which is why I got blocked after I moved).

You're absolutely incorrect about this. What you're saying may have been true a long time ago but it's 100% wrong now. In 2023/2024 you should click unsubscribe links. No matter how spammy a sender is, an unsubscribe click is a big signal that they don't want to contact that email account again. It takes time and money to warm up a domain, prepare it for outbound email, and keep it from being blacklisted when you're…

I don’t know how often I have clicked the unsubscribe link only to find I am not unsubscribed. Plus the link is always at the bottom in a tiny footer. The mark as spam button has no such issue and hurts the sender to boot.

Another data point: since 2021, every time I clicked the unsubscribe link, I stopped receiving emails from those services.

I also haven't seen those email addresses passed on to someone else (I use unique aliases).

My 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 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 wh…

sounds like you paid to have their spam filter look the other way for your ips

Little OT, I was using Hotmail in 2015 to apply to grad schools. I got an email about interview from a professor with @vt.edu address that got flagged into spam. I noticed only after someone else got selected for funding. To this day I don’t understand why an email written by a professor from a reputable university domain was flagged as spam, but I have definitely stopped using Hotmail

You may have gotten lucky with IP addresses. When your cloud provider gives you an IP address from the pool, it is luck of the draw whether some customer in the past got that IP address on the bad list with some mail providers.

I strongly want what you say to be true, and would also encourage people to self-host email, but I want to make sure people are aware of the pits so they can avoid them or at least not have to learn the hard way.

Maybe 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.

It is good practise. You should never use the unsubscribe function as it tells sender the account receives is actually in use and valid. Thus they will sell your email to even more spammers.

If it's from a generally legit company the unsubscribe function does actually work.
