Mailgun — Email API Built for Developers Who Care About Deliverability

Mailgun is a transactional email API service by Sinch that handles email sending, receiving, and validation for applications. With powerful APIs, detailed analytics, and email validation built in, Mailgun gives developers the infrastructure to ensure their emails reach the inbox.

API-First Design

Mailgun is built for developers, not marketers. RESTful APIs and SMTP relay handle sending. Webhooks notify your app about deliveries, opens, clicks, bounces, and complaints. Routes process incoming email and forward or store it. Everything is programmable.

Email Validation

Mailgun Validate checks email addresses before you send — catching typos, disposable addresses, and invalid mailboxes. Reduce bounces by 90% and protect your sender reputation. Available as a batch API or real-time check.

Deliverability Tools

Inbox placement testing shows where your emails land across Gmail, Outlook, and Yahoo. Dedicated IPs isolate your sender reputation. DKIM, SPF, and DMARC configuration guides ensure proper authentication. Suppression management handles bounces and complaints automatically.

Mailgun vs SendGrid

SendGrid offers a marketing email platform alongside its API. Mailgun is purely transactional with stronger validation and deliverability tools. SendGrid has better templates and contact management. Mailgun has better developer tooling and parsing capabilities.

Mailgun vs Postmark

Postmark delivers faster (under 10 seconds) by refusing marketing email. Mailgun handles both transactional and bulk email with more flexibility. Choose Postmark for speed-critical transactional email. Choose Mailgun for versatility.
