Premailer vs testmail.app: What are the differences?

Developers describe Premailer as "Pre-flight for HTML email". For the best HTML e-mail delivery results, CSS should be inline. This is a huge pain and a simple newsletter becomes un-managable very quickly. This script is the solution. On the other hand, testmail.app is detailed as "Automate end-to-end email tests". It automates end-to-end email tests with a powerful GraphQL API and unlimited private email addresses and inboxes, test new user signups, transactional emails, drip campaigns, deliverability, spam scores, etc.

Premailer and testmail.app can be categorized as "Email Testing" tools.

Some of the features offered by Premailer are:

CSS styles are converted to inline style attributes
Relative paths are converted to absolute paths
CSS properties are checked against e-mail client capabilities

On the other hand, testmail.app provides the following key features:

Unlimited email addresses and inboxes
GraphQL API with interactive GraphQL Playground
Live queries (API waits to receive email before responding)

Premailer is an open source tool with 2.04K GitHub stars and 340 GitHub forks. Here's a link to Premailer's open source repository on GitHub.
