Application email delivery through REST APIs and SMTP.
What is Mailgun?
Mailgun provides email delivery through REST APIs and SMTP. Developers connect it to an application or a separate newsletter tool that creates messages and manages recipients. Plans include a specified volume of email delivery.
The free plan has a daily sending cap, while paid plans provide larger monthly allowances. Optional validation, dedicated IPs, and deliverability services can add costs. Published overage rates vary by tier, so a plan’s included volume alone does not describe every possible invoice.
