WP Mail SMTP, SendGrid not working

I’m using WP Mail SMTP on WordPress to connect SendGrid. After inserting API key it’s not working. I’m wondering if I need to do something serverside to make it work.

Hi there @Kristiannthogersen,

I can suggest a few things here:

  • Make sure that you are using port 587 as your SMTP Port
  • If you have a firewall on your Droplet like UFW, make sure that you open port 587 for outgoing TCP connections
  • If you are using a Cloud Firewall make sure that port 587 is also open for outgoing TCP connections

Let me know how it goes! Regards, Bobby
