UPDATE: I finally resolved the issue. For how good Mautic is, I want to preface this with the fact that the Mautic + SendGrid integration documentation is extremely poor.

1. You must install SendGrid via composer:

composer require symfony/sendgrid-mailer

1. You must configure the Email DSN as follows:

Scheme: sendgrid+api  
Host: [api.sendgrid.com](http://api.sendgrid.com)  
Port: Leave Blank  
Path: Leave Blank  
User: Your SendGrip API key  
Password: Leave Blank

I hope this helps prevent other people from wasting hours of their time.
