See exactly what your Salesforce emails look like without sending them to a live contact.

Highlights

Test without sending to a real contact. No fake Contact records to create and clean up, and no chance that a test reaches a live customer.

See the whole email, not just whether it sent: content, HTML, plain text, headers, attachments, rendering, and spam score.

Merge fields resolve against real production records, so you catch the bug that only shows up against live data.

Iterate quickly. Send, check, tweak, and resend as many times as you need, without touching customer data or waiting on anyone.

Two fields to configure. Connect your Mailtrap account with an API token, then pick a Mailtrap sandbox. No code and no DNS.

Reversible in one click. Testing Mode is a switch inside Salesforce, and its state is shown at the top of the app.

Mailtrap (Email SandBox)
Pasadena, CA, US

Mailtrap is an email delivery platform that helps developers and product teams test, send, receive, and manage email across the complete email lifecycle. It brings Email Sandbox, Email API/SMTP, Inbound Email, and Email Marketing together in one platform, so teams don't need separate vendors for testing, production delivery, and campaigns. Founded in 2011, bootstrapped and engineer-led ever since, Mailtrap is trusted by 150,000 customers, including PayPal, Atlassian, Adobe, NVIDIA, and Walmart. Email Sandbox for Salesforce brings that same safe testing step to teams working in Sales Cloud, Service Cloud, and Experience Cloud. Beyond the Salesforce platform, Mailtrap works with major languages and frameworks, REST API and SMTP, webhooks, CI/CD pipelines, and MCP for AI workflows.
