Send emails on Rails using SendGrid

A quick email setup using Rails, Action Mailer, Devise, and SendGrid.

Step 1: SendGrid

Create an account

First, if you don't have one already, you'll need to create a SendGrid account.

Set up a sender identity

Once you're done, set up a sender identity on SendGrid. You can find this option under Settings > Sender Authentication > Verify a Single Sender, or just follow the link: https://app.sendgrid.com/settings/sender_auth/senders

Make sure to verify your email address.

Create your first API key

You can create an API key via the left menu Settings > API Keys, or follow this direct link to https://app.sendgrid.com/settings/api_keys

Make sure to create an API key with full access and store it safely. I usually keep mine within my rails credentials file.

Step 2: Rails & Action Mailer & Devise

Install rails dependencies

Start by adding the line ruby client gem to your Gemfile:

gem 'sendgrid-ruby'
