I've had the same problem with that blacklist, and I was advised that it's essentially an extortion racket: you pay to get off for some period of time, and then you end up back on. Which is exactly what happened to me.
My domain is hosted on Digital Ocean, and I was able to fix it by moving my DNS to Cloudflare, then enabling the Cloudflare DNS proxy feature so my domain would no longer be associated with an offending IP range.

Should be a process to get removed from that list, I know there is from Barracuda's blacklist as well as SpamHaus.
It could be that just not having a proper DKIM sig may trigger that blacklist though. There's a lot of blacklists out there and many work differently from one another.

That is a problem that is caused by the uptight spam filter on Gmail

play well with mail lists and tilde.club itself does not process DKIM signatures. There are a few mail protocol extensions that kind of

that issue, but the only thing that is really working is to use a
tilde.club
email to send the mails

Hello all,
I’m not sure if this is the right place to say so, but I’ve noticed
to this mailing list being persistently classified as spam when it
arrives
at my Gmail account, despite me telling Gmail it looks safe. I’ve had
to
set up a filter to whitelist the tilde.club domain. Of course, if this
is
a problem for you too, you probably won’t see this message. Seasons greetings and a pre-emptive Happy New Year to you anyway!
