Re: Our emails marked as spam by receivers

bback · 09-25-2023 08:59 AM

I have been notified by a few of our users that emails that they have sent have been marked as spam by the receivers. Some of these have been customers and suppliers.
I have checked the mx check here and the only 'error' is MTA-STS DNS Record. DKIM is setup and authenticating and everything is green.
I have run log searches for emails that have been marked and I see that everything has been delivered to a server.
If I go to mxtoolbox.com I get this: DMARC Quarantine/Reject policy not enabled. Is this something I can add?
I have asked users to make sure that the people who have found their messages in spam mark the messages as safe, but

I'm really not sure what else I can do. Any suggestions?
Thanks, Bob

Check out https://support.google.com/a/answer/10583557 for how to set up SPF, DKIM, and DMARC for your domain. Getting all of those set up will help.

Hope that helps,

Hmmm. I do think that setting up DMARC set up to do at least some level of quarantine or reject might help a bit (quarantine/reject 100 is best, start with quarantine to make sure you're not blocking anything that shouldn't be blocked). That could help a lot with your domain's reputation.

Okay, I set the quarantine policy. Let's see what happens.
Thanks,

Hi Julie,

I haven't heard any more complaints, but I don't know if anything actually changed. Sorry I can't be more help.
