Managing your own email systems in house are no longer viable option. SendGrid allows you to use a cloud-based SMTP server with numerous benefits and is very affordable.
SendGrid also allows you to track email opens, bounces, unsubscribes, and spam reports without any use of code. The SendGrid API plugin is a great option to managing your SendGrid without the use of login name and password. Just your API key.
You can signup for a SendGrid account if you do not have one. Once you access your account, you can create an API key by using the left navigation menu title Settings, and then click on API Keys.
Configuring your SendGrid API plugin is two simple steps. Just enable it and enter your API key. Your API key will be enrypted when you save.
