Frequently Asked Questions

Can Mailtrap send emails to real recipients?

Mailtrap is a testing tool and is not designed to deliver emails to real addresses. However, you can forward some messages to your colleagues, customers, or your own inboxes for testing purposes.

How can I preview my email in different email clients?

Mailtrap’s HTML Check analyzes your template for support in popular email clients and explains how to fix errors right away. This is more efficient than manual comparison of previews from email clients, but you still can forward your test emails to real recipients and open them in specific email clients.

Can I send a test email to Mailtrap from my Gmail?

Yes, you can! On Business, Premium, and Enterprise plans, there is a separate email address available for each of your inboxes. With it, you can send messages from any CRM, email sending app or client, such as Gmail, Hubspot, Sendgrid, etc.

How much does Mailtrap cost?

Mailtrap features a forever free plan that offers the basic functionality for personal use. Paid plans start from $9.99 per month, and are suitable for companies of different sizes. View the Mailtrap pricing for more details.
