Deliverability Code
Your Emails Are
Landing in Promotions.
We Fix That.
Our deliverability code moves your emails from the Promotions tab to the Primary inbox. We A/B test it on your list first, for free, so you can see the revenue lift before you spend a dime.
Book Your Free A/B Test68% of your emails never even had a chance. Subscribers didn't ignore them... Gmail hid them.
Gmail's Promotions tab is burying your emails.
You're spending real money driving traffic and building a list. But when your emails land in Promotions instead of Primary, most subscribers never see them.
It doesn't matter how good your subject line is or how beautiful the design looks. If the email is sitting in a tab they check once a week, your open rates, click rates, and revenue all suffer.
That's why we test it for free first.
We install our deliverability code on a test segment of your list. You see the results with your own data before any commitment.
Here's what's included. No strings.
The A/B test is completely free. No contracts, no commitments. If the code doesn't move your emails to Primary, you walk away with the data.

We add the code to your Klaviyo account in about 5 minutes. It's completely invisible to your subscribers... nothing changes on their end.
A/B test with your list
We split your next send into two groups. Half get the code, half don't. You see the open rate and revenue difference with your own subscribers.
Revenue lift report
After the test, we walk you through the results. If the data shows a clear lift, we talk about licensing. If it doesn't, no hard feelings.

Common questions
What exactly is the deliverability code?
It's an algorithmic code that gets added to your email sends. It signals to Gmail's filtering system that your emails belong in the Primary tab instead of Promotions. The technology works at the infrastructure level, so there's nothing your subscribers see or interact with.
Does it work with Klaviyo?
Yes. We built it specifically for Klaviyo-powered ecommerce brands, though it works with other ESPs too. The install takes about 5 minutes and doesn't require any changes to your templates, flows, or sending practices.
What does it cost after the free test?
If the A/B test shows a clear lift and you want to keep it running, the code is licensed at $4,200 per quarter. That's it. No hidden fees, no per-email charges, no long-term contracts.
What if the test doesn't show results?
Then you don't pay anything. You keep the data from the test and we part ways. We're confident enough in the code to let the numbers speak for themselves.
Will my subscribers notice anything?
No. The code is completely invisible to the end user. Your emails look exactly the same. The only difference is where Gmail places them.
