I received no response from DO, all outlook, Hotmail, MSN, Comcast, AOL users aren’t receiving our system generated emails, plus when we send it out through webmail or personal outlook it returns with an error saying that this network is on their block list. I somehow managed to fix the Hotmail issue by contacting them, they are now accepting the emails from my server, but they are sending my emails to their junk list.

The rest are in block still. How do i come out of this situation. We don’t send bulk emails, we don’t send any marketing emails, the only emails that the system sends are auto generated OTP’s or order update emails.

All other users except for the ones mentioned above are doing well and yes we have all the DNS configs, SSL etc in order.

How do you fix this, DO just thanked me for the update rather than giving me a solution, and then they became unresponsive. Should i migrate over to a different provider or is there a solution to this problem?

Hi @masscoinex,

Firstly, I’ll recommend using port 465 for sending out messages rather than 25. Port 25 is considered an unsecured port and more often than not providers block emails from it.

Another possibility is the IP of the Droplet is considered as a threat due to some reason.

I’ll recommend using an e-mail checker to see what score your E-mails rank up to. The link is here - https://www.mail-tester.com/. The way it works is you send a message to the given e-mail account and check the score of your message. It will provide you with a scale from 1 to 10 and notify you about any issues you might need to fix.

Try it out and see if after making a 10/10 score on the tester the messages will still be marked as spam.

One other thing, you know content does matter and it’s possibly Gmail are marking your messages based on it.
