Hi,

What is the error? Is may help troubleshoot the issue with you.

I can send an email from localhost but when I deploy it here it throws this error => Error: Mail command failed 530-5.7.0 Authentication Required (I am using nest.js framework, with nodemailer and Gmail as SMTP)

Nodemailer has a section on using Gmail and some of the issues that may come up: https://nodemailer.com/usage/using-gmail/

However, the error you shared seems to be related to authentication rather than a physical connection to Gmail. Most of Render runs on AWS, and I’ve seen reports that Google may also block Gmail requests coming from AWS as a way to combat potential spam bots.

Alternatively, there are dedicated email providers, like MailGun, SendGrid, etc.
