Add automations, templates, and analytics to your own SMTP or email service

Developed by developers, for developers: Keep Postmark, AWS SES or Gmail - SendStreak wraps around them with automation, templates, and email API features.

_{Trusted by Teams of All Sizes}

How it works?

SendStreak sits between your app and your email provider

Your app sends email through SendStreak. We handle templates, automations, tracking, and routing - then deliver via the email backends you connect, like Postmark, Gmail, AWS SES, or your own SMTP server.

Use One Provider. Or All of Them.

SendStreak lets you connect multiple email backends at once - like AWS SES, Postmark, Gmail, or your own SMTP server. Balance delivery, optimize cost, and maximize uptime - dynamically.

Don’t trade lean code for a $3k/month detour

_{Why do I need it?}

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

_FAQ

Have a question?

Is there a free plan or trial?

Yes. You can start using SendStreak for free with limited monthly volume — perfect for testing integrations or running small-scale email flows.

Is my data safe with SendStreak?

Yes. SendStreak stores email content, metadata, logs, and template variables - everything needed to power features like retries, tracking, and automations. All data is securely hosted in the EU and handled in full compliance with GDPR.

Can I use SendStreak with a self-hosted SMTP server?

Absolutely. You can connect any SMTP-compatible service, including servers you host and manage yourself.

What happens if an email fails to deliver?

SendStreak automatically retries messages based on the type of failure - including throttling, soft bounces, and temporary errors.

Can I use SendStreak for bulk email?

Yes. While SendStreak isn't a full-blown marketing platform, it includes powerful bulk sending capabilities - perfect for announcements, promotions, or simple campaigns.

How long does it take to get started?

Most users connect their first email backend and send a live email in under 10 minutes. You may need to move some templates initially - but once you're on SendStreak, switching email backends takes just minutes, and you never have to migrate again.

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.
