Mailsac vs Premailer: What are the differences?

What is Mailsac? Unlimited email addresses for testing. Disposable email and fake email capture for QA and development teams.

What is Premailer? 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.
