Mailtrap is a transactional email sending and testing platform used by product and dev teams to send app-triggered emails via REST API or SMTP, plus a sandbox for previewing emails before they hit production. It emphasizes deliverability analytics, spam-score checks, and an inbox-placement dashboard alongside standard suppression, webhook, and template tooling.
Developers and product teams who need to send transactional and bulk emails from their applications, and to receive/parse inbound email, without running their own mail infrastructure.
An Email Sending product (branded Email API/SMTP) offering a REST API and SMTP relay for sending, hosted HTML email templates with Handlebars variables, deliverability tooling (SPF/DKIM/DMARC, dedicated IPs on higher tiers, suppression and bounce handling), webhooks for delivery events, analytics and searchable email logs, inbound email parsing, and official SDKs for Node.js, Python, PHP, Ruby, Java, .NET, and Elixir. Mailtrap also sells a separate Email Testing/Sandbox product and an Email Marketing product with their own pricing.
Applications authenticate with an API token and send either via a POST request to the transactional REST API (send.api.mailtrap.io) or via SMTP relay (live.smtp.mailtrap.io:587), optionally referencing a template by UUID instead of inline HTML. Sent messages generate real-time analytics, logs, and webhook events, and a separate inbound-email endpoint lets applications receive and parse incoming mail via API or webhook.
