I am getting email delivery errors

  • Answered

I have two email accounts:

[email protected]
[email protected]

I sent an eBlast through Vertical Response email marketing service to a couple thousand recipients.

However, two of the email accounts that I create via InMotion were not able to receive the email due to a 550 Error.

Please check the configuration of these accounts and confirm that they do not need some kind of authentication… or some strange setting is off.

There is definitely something wrong with the configuration of these email accounts.

Another issue with these accounts is that often email from these accounts go to people’s spam folders.

When I try to email these accounts from another email address of mine, I get the following bounce error message:

Hello harrylbrownjr, Thank you for your question. If you haven't seen it before, our Bounce Back Parser tool is helpful for troubleshooting returned emails. It can also notify our systems team if any issues are identified. There are many reasons for getting a 550 email error, and we would need the full bounced message to provide an exact answer. After investigating, I was able to determine several things: The bounced error message you posted is from your sending server (for blackdiamondtechnologies), so the email is failing before it communicates with our server. This is most likely due to a misconfiguration of the sending email client (outlook, thunderbird, mac mail, etc.). Also, here is a helpful article on how to stop your emails from being labeled as spam. In the future I recommend forwarding your full bounce email to [email protected] for review. This will create a ticket, and our Tech Support team will reply upon resolution. If you have any further questions, feel free to post them below. Thank you, -John-Paul
