WP Mail SMTP, SendGrid not working

Posted May 18, 2020 208 views
API

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
