I suspected that my email to admin@rawtext.club had gone in the bin and I checked and I was right.

It seems like it's harder and harder to run your own mail server nowadays, so I had delegated the reputation part and send my outgoing SMTP via Sendgrid. AFAICS the reliable-delivery-Internet is three or four massive ISPs, Google, Microsoft, Sendgrid and Mailchimp. Everyone else is just rolling the dice when sending email.

It turns out that _even if you're using Sendgrid_ you are also rolling the dice on whether they use one of their IPs which is on Spamhaus' list.

Oh, well. At least I can sign up for gemlog.blue without reliable email!
