SendGrid EMail Api: 500 Server Error

Posted July 28, 2018 2.7k views

I need a system where I am notified when a customer fills the contact form. I am using the SendGrid Python API tutorial here. and I get a 500 server error. It works fine in development and I am even able to send mock emails accessing Python console on Ubuntu. Is the problem related to the blocking of SMTP port or is it something else. Any help would be appreciated.

If anyone encounters this problem in the future while using using the SendGrid python tutorial,
instead of

sg = sendgrid.SendGridAPIClient(apikey=os.environ.get('SENDGRID_API_KEY'))

do this

sg = sendgrid.SendGridAPIClient(<Your API Key>)

That was the problem.

Heya,

You could try pinging the SMTP port to see if it’s being blocked. Here you go: https://ping.eu/port-chk/

  • Hey Alex,

    Thank you for the link. I have come across posts mentioning that the SMTP ports are closed by default due to the spam mailing problem. For the life of me, I can’t figure out how to get email APIs like sendgrid to work on DO as well. Will keep trying.
