    About

    In practice. What you can do with Mailgun.

    Mailgun is an email-sending API built for developers: transactional emails (confirmations, password resets), address validation, real-time tracking, and built-in SPF/DKIM/DMARC management.

    Since the Sinch acquisition, several users report 20-40% price increases and a measured drop in deliverability (from 53.8% to 26.05% between Q1 2024 and Q1 2025 per GlockApps) — a point worth watching before committing. Mailgun offers no email templates or automated follow-ups: for marketing campaigns, SendGrid, Mailchimp, or Brevo are better suited.

    Practical uses

    • Send transactional emails from SaaS apps.
    • Build triggered email workflows via API.
    • Handle bounce and complaint management at scale.
