Email API
Mailgun
Email API for sending, receiving and tracking transactional and bulk email, owned by Sinch since December 2021.
A developer email API with detailed delivery and failure events.
Founded in 2010 and based in San Antonio, Texas, Mailgun became part of Sinch when Sinch completed its acquisition of Pathwire, the owner of Mailgun and Mailjet, in December 2021. Webhooks report deliveries and separate temporary from permanent failures, and plans with published overage rates are listed per 1,000 emails. Worth a look when email notifications are part of the product and the team wants to handle bounces programmatically.
Where it shines
- Delivery, temporary-failure and permanent-failure events by webhook
- Public status page with incident history and subscriptions
Check before signing
- Plan names and included volumes have changed; compare the current plan and its overage rate per 1,000
- Email only: SMS or WhatsApp need another provider or a separate Sinch contract

Something is listed only when it can be checked. A connection we could not confirm is left off, and Find providers then credits the API at half weight.
