About

Mailtrap started as a tool for safely testing emails during development (catching them in a fake inbox instead of spamming real people), and now offers real email sending too. The $0-forever plan includes 4,000 emails a month (150 a day), one sending domain, and 3 days of logs. With no credit card required to sign up.
