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...
