Hi,
All newsletters are sent from our email address to addresses on the mailing list. Sending newsletters to a mailing list (a list containing email addresses) is standard practice. The mailing list might have a name that looks generic, but that is entirely normal. All newsletters sent to such mailing lists are still sent from our avast.com email address.
You're still not answering my question so your responses aren't helpful.
For the umpteenth time, why the need for "7238189.xt.local" and different numbers for each mailing list, if not to evade spam filters and unsubscribes? Why not only use the @emails.avast.com address?
I think you got a proper answer already.
They don't email every single subscriber separately. They use a system called "email list", so it holds a lot of people's addresses in that group, and that's why you see those "xt.local" there.
So, it works like this: every separate thing people can subscribe to is handled by a separate mailing list, that contains all those people who are subscribed. It's used to easy organization of such subscriptions.
I researched it a bit, and turned out it's a common problem in general with people having problems with stopping spam from various companies who use email lists like that to mass send emails.
But, I can offer you a solution.See this post I'm linking from one reddit discussion about the issue with such kinds of spam in general:
https://www.reddit.com/r/GMail/comments/lboly0/gmail_spam_what_is_xtlocal/h2zsgqy/People in replies confirmed there that this method works!
And in general, letting google deal with spam automatically isn't the best way. It's actually a lot more efficient to create various filters for your mails. Some could automatically put emails into a Spam folder, and some could auto-sort your emails to different categories (labels) so you can have emails from different sites completely separate from each other.
