Mailgun

Mailgun is a cloud-based email delivery service designed specifically for developers and businesses who need to send emails programmatically through their applications.

The platform offers both RESTful APIs and SMTP relay services, giving developers flexibility in how they integrate email capabilities. Unlike traditional email marketing platforms with drag-and-drop editors, Mailgun focuses on programmatic email sending with features like real-time tracking, webhook notifications, and detailed delivery analytics.
