Independant emails are not delivered to the major mail hosting providers such as gmail...

Right now institutions don't talk about regulating email simply because they take it for granted, but it's not.

Email has superpowers, one of which is unique subject lines. What I should have done is broken up the email into three separate ones, with different subject lines, each tailored to my desired outcomes.

1. Subject: Come visit my new place. Why I moved.
2. Subject: My availability reduced until February 10
3. Subject: New Address – Keep for reference and update your Contact for me.

This allows each recipient to ignore or archive each topic if not relevant or interesting to them, or to keep the actionable ones. It also not-so-subtly puts my desired outcome into their subconscious. It requires almost no additional work on my part to send three emails versus sending only one.

It is better to have small emails than bigger, so one email for each topic.

Emails are not good enough: they can change.

The problems lasted weeks and it is now solved in one day after being public...

It's amazing how quickly Microsoft can fix things if issues are made public: Yesterday we've reached out to Microsoft Germany along with the press release asking them - again - to fix the issue of tutanota.com emails going to Spam in Outlook. The issue was then fixed within one day (after we had been in direct contact for three weeks without any success)!

It follows the SAML:

the identity provider gives some claims1. One that it provides is the NameID, inside of Subject.

What Atlassian/Jira is doing right is that they're actually using a static identifier to identify you, rather than your email address. This allows an incredibly smooth experience when any aspects of your attributes (such as email or name) change.

An ode to email <3

keep your crusty gmail account around for spam and trials and signups and
whatever else, and get yourself a fastmail.com account. or a migadu.com account
if you're a techie.

set email type to plaintext-only. this email account will only ever send
or receive text.

email waits patiently. it sits still and does not make a fuss. if your friend
doesn't respond, send another email to another friend. the conversations move
slowly, sometimes over the course of many years. this is the antithesis of
modern communication.

think of email the same way you'd think of a penpal.

email connects people intimately and loosely.

I think it would be better if he mastered rules and filters and stick to one inbox

I totally agree
