Email Built for Startups
Launch for free, scale with BYOK. The deliverability of SendGrid at the price of AWS SES.
The Challenges
Why Startups email is hard
Expensive 'Pro' Cliffs
Standard providers jump from $20/mo to $250+/mo the moment you need a dedicated IP or higher volume.
Manual Warmup Pain
Spending weeks manually ramping up volume to avoid the spam folder is a waste of precious engineering time.
Vendor Lock-in
Once your templates and data are in a proprietary system, moving to cheaper infrastructure is a technical nightmare.
The Solution
How Transmit helps Early Stage
Automated Warmup
Just set your target volume and we'll handle the ramp-up schedule, auto-pausing if your bounce rates spike.
The Hybrid Model
Start on our managed infrastructure. When you hit scale, swap in your own AWS SES keys without changing a single line of code.
Foundational Security
SPF, DKIM, and DMARC setup in 1-click. We focus on the protocol so you can focus on your product.
Developer Experience
Quickstart for Developers
Our API is built for the modern edge. No heavyweight SDKs, just simple REST and standard protocols.
