Transactional Email API Service For Developers

Unclaimed

By Mailgun (a Sinch company)

Mailgun is a developer-focused email delivery platform that sends transactional and marketing email at scale through a RESTful email API and SMTP relay.

What it does
  • Mailgun is a developer-focused email delivery platform that sends transactional and marketing email at scale through a RESTful email API and SMTP relay.
More detail
  • It also covers inbound email parsing via routes, email list validation, and deliverability and email testing tools.
  • It is built for engineering teams integrating email directly into their applications rather than for non-technical users seeking a full marketing or CRM suite.
Best for
  • Application developers and engineering teams who need to programmatically send transactional email such as order confirmations, password resets and notifications, and high-volume senders who need API or SMTP scale.
More detail
  • It also suits teams that need inbound email parsing, list validation, or deliverability and inbox-placement tooling alongside sending.
Pricing
  • Usage-based SaaS billed as a monthly subscription plus metered overages on extra emails and extra validations.
More detail
  • List prices in USD: Free is $0/mo with 100 emails per day, 1 custom domain, 1 API key, 1-day log retention and 1 inbound route.
  • Basic starts at $15/mo with 10,000 emails/mo, 5 inbound route
Main limitation
  • Very light or non-technical users who want a full marketing suite with CRM or marketing automation, since Mailgun is API and SMTP first and explicitly built by developers for developers.
More detail
  • Also a poor fit for anyone needing more than 100 emails per day on a free plan, or long log retention on lower tiers.
