Mailtrap

Mailtrap is a hosted email API, SMTP and email sandbox service for testing and sending email, run by Railsware Products Studio LLC. The documentation describes the platform as email infrastructure for developers, and its security page says customer data is hosted in US data centers. Mailtrap’s own pages present it as an alternative to Mailgun and Amazon SES.

Worth knowing

Mail goes through the vendor’s hosted infrastructure, so nothing is installed by the user. Single sign-on through the customer’s identity provider is listed for the Enterprise plan.
