Email Framework as a Service
Turn AWS SES, Gmail, or your own SMTP into a complete email platform: queues, retries, templates, analytics, and smart routing from a single API. SendStreak plugs into one or multiple email providers at once, so you can balance cost and deliverability while we handle workers, logging, and delivery logic for you.
How it works?
SendStreak sits between your app and your email provider
Your app talks to a single email API. SendStreak acts as the framework in the middle: it handles queues, retries, templates, tracking, and routing, then delivers through whichever email services you’ve connected—whether that’s AWS SES, Gmail, Postmark, or a plain SMTP server.
Use One Provider. Or All of Them.
SendStreak lets developers plug in multiple email backends at once and treat them as one unified service. Route traffic between providers to balance cost and deliverability, add automatic failover, and keep your app code simple while the framework handles the routing logic.
You chose the smart path
You’re sending email through a reliable backend - AWS SES, Postmark, Gmail, SMTP - without the SaaS bloat.
You’ve saved money and kept control - at the cost of your focus:
- dangerous You’re parsing bounce codes to retry failed emails
- dangerous Rendering templates in code
- dangerous Logging delivery outcomes manually
- dangerous Lacking automations or scheduling
And the longer this goes on, the closer you get to...
The detour: Full-stack ESPs
When you’re tired of rebuilding logic, it’s tempting to switch to bloated, expensive platforms like Mailchimp, Customer.io, or SendGrid’s automation suite.
You escaped infrastructure headaches — and entered a vendor trap:
- dangerous Your templates, logs, and workflows are locked into one provider
- dangerous Migrating away means starting from scratch — losing history, templates, and internal logic
- dangerous And as your volume grows, so does your bill - rapidly
There’s a better balance between raw email infrastructure and feature-rich delivery

Why is using SendStreak not just another form of vendor lock-in?
Because with SendStreak, you're never locked into a single email provider. Most teams don't leave full-stack platforms because they lack features - they leave because of delivery issues or ballooning costs. With SendStreak, switching providers takes just minutes. One moment you're using AWS SES, the next you're on SMTP.com - no downtime, no code changes, no loss of history or templates.
