Gmail consistently sending mailbox.org emails to Spam despite SPF/DKIM/DMARC passing

Emails sent from my email are consistently being classified as spam by Gmail.

I tested delivery to two separate Gmail accounts and both messages were placed in Spam. A plain text message with no attachment and a separate message with an attachment were both affected. Delivery to Proton Mail succeeded normally.

Gmail reports SPF: PASS, DKIM: PASS and DMARC: PASS. The messages were delivered via mailbox.org outbound server

Gmail’s reason is: “This message is similar to messages that were identified as spam in the past.”

Has anyone else had this? This is a significant issue for me because I need reliable delivery to Gmail recipients for my work emails correspondence. If mailbox.org can't resolve the deliverability problem, I unfortunately need to move to another provider. I really want to stay with Mailbox.org as I love it so far but this is a crucial problem for me.

I notice it too. Seems a way of Google-Gmail deliberately bothering / discouraging other email providers. After all, nothing is wrong with the email itself. Still i hope something can be done about it.

So far i really do like mailbox.org.. !

I recently experienced the same: two emails not being delivered to the correct GMail inbox. Only an acquaintance, so I did not ask about spam...

On the other hand, my plan is anyway to block incoming emails from GMail, as all my answers will be monitored by Google for ads and AI training. I just need to get my mother off from her old GMail account :-)

Hi,


Looks like one of the things that Google recommends to prevent valid emails from going to Spam is to add the email address of the sender to Google Contacts. I know this may not be possible in every single scenario, but you may try asking the recipient to add the Mailbox.org address to their Google Contacts before you send them the email. That may be a valid workaround in some cases.


I found this link which also suggest a few additional steps https://support.google.com/mail/answer/1366858


I hope that helps.


Regards,

Fred.

Hello,


Can we please have an answer to this issue? I have just joined mailbox with the intention of using it for business purposes, and noticed that I was not receiving replies from potential clients. I ran a test with different providers- proton mail and hotmail/outlook successfully delivered, while 3 out of 4 Gmail accounts sent the email to spam.


Please provide some support- I would like to stay with Mailbox if possible but as I can’t see any clear resolution to this, so will likely have to seek an alternative.


Thank you.
