What I can recommend from my own experience: 1) create some actual test account on Gmail 2) make your customer send an email to this account using your process 3) access the Gmail account and see if message actually went to Spam folder. If yes: 4) check if Gmail indicates all three SPF, DKIM and DMARC on the message as PASS. If not, you need to fix the one that is failing on your side and re-try. 5) If yes, send the headers of the message that was incorrectly classified as spam (the headers as received on that Gmail account) to Google using this form: https://support.google.com/mail/contact/bulk_send_new . They explicitly say in the form that they won't reply to you, but it often really helps and your messages are no more going to Spam (at least that was in my case). Before you do step 5), you may also try what they say on their sender guidelines page: "If your email has a link to a site with bad email practices, it could be marked as spam. You can remove the link to see if the classification changes from spam. If it does, we suggest sending the email without the link or ending your program with the site.". So, if it is possible to change the email so that it doesn't contain any links, and resend it, it is worth trying. My messages had no links at all, so I simply skipped that step. And, also don't forget to mark the message as "non-spam" on the test account that received it, or even reply to the message. It is some signal (although weak, if only one user does this, but still some) to the Google's AI to not classify this kind of messages as spam. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
