Introducing AISend: AI-Powered Email API
Why we built AISend
Email is the backbone of every application. Password resets, welcome emails, receipts, notifications — they all depend on reliable delivery. Yet most email APIs treat every send the same way: accept the request, pass it to a single provider, hope it lands in the inbox. We thought there was a better way. AISend applies machine learning to every aspect of email delivery — from choosing the best provider for each recipient, to optimizing send timing, to scoring content before it leaves your server.
The problem with traditional email APIs
Traditional email APIs are essentially a thin layer over a single email provider. When that provider has issues, your deliverability drops. When a recipient's domain is tricky, you have no fallback. There's no intelligence in the pipeline — just a queue and a prayer. Developers end up building their own retry logic, provider failover, and deliverability monitoring. That's infrastructure you shouldn't have to maintain.
How AISend is different
AISend routes each email through the best available provider — AWS SES, Postmark, or SMTP — based on real-time deliverability data. Our AI scores your email content before sending and suggests improvements. Send time optimization ensures your emails arrive when recipients are most likely to engage. And our API is designed to be Resend-compatible, so migration takes minutes, not days.
Developer-first, always
We're developers building for developers. Our REST API is clean and predictable. SDKs are available for Node.js, Python, Go, and Ruby. The dashboard shows you what matters — deliverability metrics, not vanity analytics. And the free tier gives you 1,000 emails per month with all AI features included. No credit card required.
What's next
We're just getting started. Coming soon: AI-powered template generation from natural language prompts, advanced analytics with deliverability forecasting, and webhook-driven automation workflows. Follow us on Twitter for updates, or sign up today to start sending smarter emails.
