How does the A/B test pick which timer a reader sees?

From their subscriber ID, which your email platform fills into the image link. The same person sees the same variant on every open and every device, so the results aren't muddled.

Which plan includes A/B tests?

A/B tests are part of the Business plan. See pricing.

Do I need two emails for the test?

No. One email, one embed code. flashtimer decides which timer each reader sees when they open it.

Why it works

What makes this email work

Specs where a tech buyer looks for them. Each product row reads like a spec sheet: what it is, the one number that matters, the price.
A 24-hour sale shows only hours. With the days hidden, the timer starts at a number that feels urgent rather than one that says there's plenty of time.
The code is part of the deal, not the small print. VOLT24 sits in its own box, ready to copy.
The test answers a real question. Pill or rings: the A/B test settles which style earns the click, so next year's email starts from data.

Subject lines

Other subject lines to try

Test two against each other. The timer stays the same, so you learn what the words do.

Build it

Build it in flashtimer

1Make two timers
Create the pill-style timer in cyan, then duplicate it and switch the copy to Rings in violet.
2Start an A/B test
Add both timers to a new A/B test. flashtimer gives you one embed code that shows each reader one of the two.
3Track the clicks
Add the test's click link to the button, so flashtimer can tell which variant sent people to the sale.
4Make the winner permanent
When one style pulls ahead, choose Make A the winner or Make B the winner. The same embed code then shows it to everyone who opens the email later.
