Nope. We're an ESP ourselves. Mailgun has delivered (and accepted) many billions of emails since our launch a few years ago. We have a lot of data on 99.99% other ESPs in the world and the most common misspellings for them. We also have ESP-specific data on what kind of RFC-compliant email addresses they do not allow.
