AISend vs Mailgun
A Modern Mailgun Alternative
Mailgun was a developer favorite, but rising prices and a sprawling platform have pushed devs to look elsewhere. AISend offers a clean Resend-compatible API, a 3-day free trial (500 emails, no credit card), and flat pricing.
Why Developers Switch from Mailgun
- Free tier is limited and time-boxed; a card is required to keep sending
- Pricing has increased significantly over the years
- No Resend-compatible request format — more migration work
- Owned by Sinch — enterprise focus over solo and indie developers
