My plug-in that @johnny recommended is fully setup to work with 3 email providers (postmark, sendgrid, mailgun) as well as has the unlayer builder.

If you provide the error you’re getting from sendgrid I can possibly provide some guidance however I will warn sendgrid send email action was having issues with the API builder so I ended up just building it as a JS action in my plugin.
