One campaign, Three builds
Identical appearance. Completely different code.
Your recipients see the same email. The inbox providers see code built specifically for them.
The problem
One size fits all HTML is a gamble.
Gmail, Yahoo, and Outlook all have different rendering engines, different spam filters, and different preferences for how emails should be structured.
How it works
You create one email. We build it three ways.
Inbox specific models
Models tuned on over 1.5 billion sends rebuild every campaign for its destination.
Zero configuration
No settings to manage. The rebuild happens automatically for every email.
Three native builds
One campaign becomes purpose built Gmail, Yahoo, and Outlook variants.
Per inbox tuning
What we optimize per inbox.
Every element is tuned for where it's going.
HTML structure
Different DOM structures, table layouts, and element hierarchies for each inbox's rendering engine.
Image handling
Image formats, compression, dimensions, and loading behaviors optimized per inbox.
Alt text
Alternative text structured and formatted for each provider's accessibility and spam systems.
Text to image ratio
The right balance, calibrated to what each inbox's spam filters consider optimal.
CSS and styling
Inline styles, selectors, and fallbacks tailored to each rendering engine's support.
And more.
Dozens of invisible optimizations working together to maximize deliverability.
The best deliverability is the kind you never have to think about.
Click rate increase
A stable, native render makes the next action easier to take.
Native inbox builds
One design is rebuilt for Gmail, Yahoo, and Outlook.
Table stakes
Plus everything you'd expect.
All the standard deliverability features, handled automatically.
