One layer between your app and every email backend you run.
Plug in several providers at once and treat them as one service. Your app makes one call. SendStreak renders, routes, retries and logs.
Raw infrastructure or a bloated platform. Pick neither.
The smart path
Raw SES or Postmark is cheap and reliable. Then you spend weeks rebuilding templates, bounce parsing, retries and logs yourself.
The detour
A full email SaaS has every feature, plus a migration, a price that climbs with volume and a vendor you can't easily leave.
SendStreak + your backend
Keep the infrastructure you already trust. Get the platform features on top, at a price that stays boring.
| Feature | Just your backend | Full email SaaS | SendStreak + your backend |
|---|---|---|---|
| Templates | Code-based, no preview | Usually a visual editor | WYSIWYG + HTML editor |
| Retry logic | Manual bounce parsing | Hidden | Built in, smart per backend |
| History | You build it or go without | Limited to their system | Logs across all backends |
| Automation | You write the scheduler | Platform-bound workflows | Integrated, stack-agnostic |
| Stack control | Flexible | Locked to the vendor | Multi-vendor, automatic |
| Cost | Low, until dev time adds up | Expensive at scale | Low and transparent |
Everything you were going to build next sprint.
Templates
Edit in HTML or WYSIWYG. Preview as Gmail, Outlook and Apple Mail before anything ships.
Retry logic
Throttling, soft bounces and transient errors are retried per failure type, across backends. No scripts.
Activity logs
Every email from every connected provider in one searchable place.
Intelligent routing
Critical mail through premium providers, bulk through cheaper ones. Automatically.
Analytics
Opens, clicks and bounces tracked across your whole stack, not per vendor.
EU data residency
Content, metadata, logs and template variables stay on EU servers. GDPR compliant.
Questions devs ask first
How long does setup take?
Most people connect their first backend and send a live message in under ten minutes.
Does it work with my self-hosted SMTP?
Yes. Any SMTP-compatible server works, including ones you run yourself.
What happens when a send fails?
SendStreak retries automatically based on the failure type: throttling, soft bounces and temporary errors each get handled differently.
Isn't this just another lock-in?
Your backends stay yours. Switching providers takes minutes, with no code changes, downtime or data loss.
Can I send bulk email?
Yes. It isn't a full marketing suite, but bulk sending is built in.
Where is my data stored?
On EU-based infrastructure: content, metadata, logs and template variables, fully GDPR compliant.
Your first email through SendStreak, in under 10 minutes.
Connect a backend, grab an API key, send. Keep everything you already run.
