Letters from a corporate mailbox end up in gmail.com spam, how to fix it?

Question

gmail

Good afternoon! From our working mail like "[email protected]", all letters coming to clients whose mail is on gmail. get into spam. We do not send spam and do not understand why this happens. From other mailboxes of the type ***@name.md, letters do not fall into spam.
Please tell me how to fix the problem! Thanks

Answer 1

Looked at the titles, in principle, there is not much difference.

Answer 2

try to remove links from the letter, all sorts of signatures, for example, with presentations, etc.

Answer 3

Check your domain for blacklisting ( mxtoolbox.com/blacklists.aspx). I myself recently encountered such a situation, letters from a corporate domain end up in spam despite the presence of SPF and DKIM, it turned out that the domain is present in one blacklist. Sent an unlisting request, waiting for a response from them
