AISend vs SparkPost
A Developer-First SparkPost Alternative
SparkPost (now Bird) was known for high-volume sending, but the acquisition brought a heavier platform and enterprise pricing. AISend offers a clean Resend-compatible API, a generous free tier, and no credit card to start.
Why Developers Switch from SparkPost
- Acquired by Bird (MessageBird) — product direction has shifted
- Enterprise-focused pricing not ideal for startups and indie devs
- No Resend-compatible request format — more migration work
- Heavier setup compared to modern transactional APIs
