I just got an email from Mastadon about Threads federating. I closed my Mastadon account about 5 minutes after joining.
I received an email about threads and Mastadon a bit ago. The thing is I deleted my Mastadon account a hot minute after I created it. The email has no way to unsubscribe from it
I would like to be comforted that I’m overthinking this. My Mastadon account was a couple of years ago in both creation and deletion. It’s incredibly disconcerting.
You don't have an account with Mastodon. You have a Mastodon account with sdf.org. Their mailing list that sent the email and the Mastodon instance they run are probably separate systems. You can forward your email to membership@sdf.org and ask to be removed.
Just a reminder that "Mastodon" is the software, not the specific service provider. Mastodon.sdf.org is different from, say, Mastodon.social even though they run the same software.
If you haven't already, you should contact the admin for that instance with your concerns. The contact the site lists is mastodon@mastodon.sdf.org
Already done but more concerned about my data having been stored and no way to ask to have it removed directly. Thank you for your response though. I’m in the UK and the right to be removed from their mailing list is the very least a business related email is supposed to offer.
That e-mail isn't from Mastodon, it's from SDF.org. It relates to their Mastodon instance - and Mastodon in general - but it's specifically an update relating to the service they offer.
Might want to check to see if you have an account there.
