Why do I need SendGrid?
SendGrid is a popular, reliable email delivery service. It is useful in situations where a customer's mail server doesn't allow relay, or when the mail server is inaccessible from the Eclipse server (e.g. for new Microsoft Azure deployments, where port 25 is blocked for security reasons), or when a customer wants more insight into the delivery of their Eclipse emails. The recommended Pro version of SendGrid service costs around $90/month, but some customers who send fewer emails are satisfied with the Essentials plan, which costs around $15/month.

Create a SendGrid API Key
Open the API Keys page: https://app.sendgrid.com/settings/api_keys
Click "Create API Key"
For the "API Key Name", you can use whatever value you want to describe the function (e.g. Eclipse Outbound Email)
For "API Key Permissions", select "Restricted Access" and then enable only "Mail Send"
Click "Create & View"
On the next screen, you will see the API Key -- copy the long string of text and save this to your notes, because you will need it for the next step, and it will never be shown again:
