Gmail Module bug: "535: EAUTH: Invalid login: 535-5.7.8 Username and Password not accepted. "

Not sure what to say about this one. We’ve been experiencing issues with the Gmail module for at least the past week. The 535 error presents itself, despite there being a valid connection in place.

There is nothing wrong with the username and password, but the scenario acts as if the credentials were changed. I’m aware of the Outlook module “swapping” users under the hood, but this error is a strange one.

Any ideas, people? Thank you in advance!

This is probably an anti spam mechanism built into gmail. Maybe try an alternative emailer built to send bulk email like mailgun?

Welcome to the Make community!

For technical issues or bugs like this, directly contacting support can often lead to a faster resolution. They have access to your specific account details, scenario and scenario logs, server-side logs, and internal tools and resources, which allows them to investigate more thoroughly than what you have access to. Additionally, sharing sensitive information about your account or scenario might not be suitable for an open forum discussion.

You can open a new ticket here, or if you are unable to login for some reason, you can create another new free account to access the ticketing system (which is only available to logged-in users). Alternatively, you should be able to send an email to helpdesk@make.com and support@make.com and it should create a ticket. After submitting a new ticket, you will receive an automatic confirmation email with the subject “Ticket Created” in the subject. If you do not receive this, try sending the ticket again.

If you manage to get your issue resolved with support, we’d still love to hear about it! Sharing your solution on the forum can help others facing similar problems.

Hope this helps! Let me know if there are any further questions or issues.

P.S.: Investing some effort into the Make Academy will save you lots of time and frustration using Make.

Very interesting, any idea how this is triggered? Is the Gmail module not designed for bulk messages? Mailgun could well work, I have been experimenting with a system called Nylas so could probably send via a HTTP module with POST.

Definitely not. It’s for personal and work use.
