Same email. Different DNA.
Every email is rebuilt from the ground up for Gmail, Yahoo, and Outlook. The same design your customers see, with completely different HTML underneath, optimized for each inbox's requirements.
Identical appearance. Completely different code.
<table role="presentation">
<img alt="hero" />
<span style="gmail-css">...</span>
</table>
<div class="yahoo-wrapper">
<img src="inline-base64..." />
<span style="yahoo-css">...</span>
</div>
<!--[if mso]>
<v:rect></v:rect>
<![endif]-->
<style>.outlook</style>
Your recipients see the same email. The inbox providers see code built specifically for them.

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.
Most email platforms send the exact same HTML to every inbox and hope for the best. What works perfectly in Gmail might break in Outlook. What passes Yahoo's spam filters might trigger Gmail's.
You create one email. We build it three ways.
Automatically. No extra work for you.
No settings to configure. It just happens, every time, for every email.
What we optimize per inbox.
Every element is tuned for where it's going.

Alt text
Alternative text structured and formatted for each provider's accessibility and spam systems.
