Each variant starts from a one-line brief, designed in your brand, ready to test against the others.

We send a few designed variants of each campaign — different subject lines, openers, offers or layouts — rotated evenly across your whole list, not a sample. You see each one's results, human opens apart, and you pick the winner.
THE OLD WAY OF TESTING
A typical split test sends two versions to a small slice of your list, waits an hour, then calls a winner and blasts it to everyone else. That slice might be a hundred people out of five thousand.
The scoreboard moves within minutes, before a single human has opened a thing. Security scanners open test emails automatically and click links automatically, and they get counted right alongside real interest, so the "winner" is often just whichever subject line a scanner liked best.
You end up sending the rest of your campaign on a guess dressed up as data, to people who never got a say in it.
HOW FAIR TESTING WORKS
Here's what happens between the send and your real winner.
Our team creates two, three or more versions of your campaign: different subject lines, openers, offers or whole layouts.
Every variant goes to an even share of your entire audience, not a small sample, so the test runs at full size from the start.
Opens, clicks and replies are tracked for each version on its own line, with human opens kept apart from automated ones.
Compare the real numbers and choose which version worked. Nothing gets crowned automatically on noisy early results.
THE DETAILS
Here's exactly what sits behind that one headline: more versions, a fair split, and results you can trust.
VARIANTS, YOUR WAY
We launch your campaign with multiple variants: different subject lines, different openers, different offers, even different layouts entirely, each one designed by our team.
ROTATED EVENLY, NO SHORTCUTS
Every variant goes out to an even share of your entire list at the same time, not a test group of a few hundred. A list of five thousand testing three subject lines means close to seventeen hundred people see each one.
RESULTS YOU CAN TRUST
Each variant's results show opens, clicks and replies on their own line, with human opens reported separately from the automated opens that come from security scanners and preview tools.
WHAT IT MEANS FOR YOU
Five ways a fair test changes what goes out next.
Every send becomes a real experiment, run at full size, not a coin flip dressed up as strategy. You see exactly which subject line, offer or layout your audience responded to, with the numbers to back it.
With the whole list split evenly, your test reflects your actual customers, not a guess about a slice of them.
Human opens and automated opens sit in separate columns, so a scanner opening a test email is never mistaken for a customer who cared.
Nothing gets crowned on an hour of early, noisy numbers. You choose when the results are in and which version goes forward.
Different subject lines and layouts going out together keep your campaign from landing as one identical message to every inbox provider at once.
COMPARED TO THE USUAL SPLIT TEST
QUESTIONS
It's a fairer version of it. Every variant goes to an even share of your whole audience, not a slice, and results count real people, not scanners opening mail automatically.
As many as your test needs, whether that's two subject lines or several combinations of subject line, opener, offer and layout. Our team designs every one.
Every open is classified as human or automated the moment it happens, and the two are reported in separate columns, so an automated open never gets mistaken for a customer.
Whenever you decide the results are in. Nothing is crowned automatically on early numbers, so you can wait until enough of your audience has had a chance to open and click.
No. Every variant still reaches its even share of your whole audience, so you're never testing on a small group and guessing about the rest.
Yes. We vary the opening line, the offer or the whole layout, not just the subject line, and compare all of it the same way.
The opposite. Sending different versions to different parts of your list keeps your mail from looking like one identical blast to every inbox provider at once.
Any list works. The split is even whatever size your list is, so the share each variant reaches simply scales with your audience.
