Mailtrap

Mailtrap brand colours

Extracted from the artwork and ranked by how much of the mark each covers — not from a brand book, so treat them as observed rather than official.

Mailtrap started as the standard way to catch outbound mail in staging — a fake SMTP inbox that shows you the rendered message, spam score and HTML issues without risking a real send. It has since added a production sending stream with templates, analytics and an EU region. The testing half is still the best in this list; the sending half is competent but younger than its competitors.
