Sendgrid is an API for sending emails. Connecting Paragon to Sendgrid takes only a few seconds, and lets you build workflows that send emails with Sendgrid. For example, you can build a workflow that sends your new users a welcome email, or a workflow that re-engages your inactive users with a reactivation email.
