The testing gap

You're optimising blind. That costs you money.

Most marketing teams launch campaigns and hope for the best. No controlled tests, no statistical rigour, no revenue tracking. Every untested assumption is money left on the table.

Guessing which popup works

You launch a popup, check the numbers a week later, and wonder if a different headline would've worked. No variants, no controlled test — just gut feeling.

Most teams never A/B test their capture widgets

Email tests are manual and slow

Testing subject lines means creating duplicate campaigns, splitting your list manually, waiting days, then comparing in a spreadsheet. Most teams skip it entirely.

68% of marketers send without testing

No way to test sequences end-to-end

Your welcome sequence has 5 emails. Is the 3-day delay better than 2? Would removing email 4 improve conversions? No tool lets you test the full flow — until now.

Sequence testing requires a purpose-built tool

Don't guess. Experiment.

Visisto's experiment builder lets you test widgets, emails, sequences, and webpages — then picks the winner automatically at 95% statistical confidence. Every decision backed by data.

4 experiment types

Test widgets, emails, sequences, and webpages.

Purpose-built experiments for every layer of your marketing stack. Not just subject lines — full sequence flow testing and split URL testing with revenue attribution.

Widget Variant testing

Test widget variants on the same surface and compare capture performance. Spin wheel vs exit intent. Different headlines. Different rewards. Find what converts.

Email Variant testing

Test alternatives in broadcasts and sequence sends. Subject lines, body copy, CTAs, send times — A/B test any element with automatic winner selection.

Sequence Variant testing

Test alternate sequence paths and compare downstream conversion outcomes. Different delays, different email counts, different conditional logic — full flow testing.

Webpage Split URL testing

Send traffic across URL variants, preserve UTMs, and measure conversion lift. Test landing pages, product pages, or checkout flows with clean attribution.

Automatic winner detection

Visisto calculates statistical significance in real-time. When confidence reaches 95%, you're notified with a clear winner and one-click promotion.

Revenue attribution

Don't just track clicks — track revenue. See which variant drives more purchases, higher AOV, and better LTV. Connect experiments to real business outcomes.

How it works

From hypothesis to winner — in 4 steps.

No code. No middleware. No learning curve. Set up once and let Visisto handle the rest.

01

Choose your experiment type

Pick from 4 types: Widget Variant, Email Variant, Sequence Variant, or Webpage Split URL. Each is purpose-built for its domain.

02

Create your variants

Duplicate and modify. Change a headline, swap a widget type, adjust timing, or test a completely different approach. No limits on variants.

03

Set traffic split and run

Choose your traffic allocation (50/50, 70/30, or custom). Visisto distributes visitors evenly and tracks every interaction.

04

Get statistical results

Visisto calculates significance automatically. When confidence hits 95%, you'll see a clear winner — with one-click promotion to make it live.

Experiment comparison

More experiment types. Better attribution.

We A/B tested spin wheel vs exit intent on mobile. Spin wheel won by 3.2× — we never would've known without Visisto's experiment builder. That single test added 1,200 contacts/month.

Subject line testing used to take me half a day. Now I create 5 variants, Visisto picks the winner at 95% significance, and I move on. Open rates up 28% since we started.

Sequence variant testing is the feature I've been waiting years for. We tested a 3-email vs 5-email welcome flow and the shorter one converted 19% better. No other tool does this.

Visisto supports 4 experiment types: Widget Variant (test different popup/widget types on the same page), Email Variant (test subject lines, body copy, CTAs, send times), Sequence Variant (test complete email flow paths and measure downstream conversion), and Webpage Split URL (split traffic across different URLs with UTM preservation).

Yes. Basic A/B testing is included on all plans, including free. You can test widget variants and email subject lines. Advanced experiments (sequence variants, split URL testing) are available on Growth (£59/mo) and Agency (£199/mo) plans.

Visisto calculates statistical significance in real-time using Bayesian methods. When confidence reaches 95%, you'll see a clear winner notification with the performance delta. One click promotes the winner to 100% traffic.

Yes — this is Visisto's unique Sequence Variant experiment type. You create two or more sequence variants (different email counts, delays, conditions, or content) and Visisto splits new contacts between them, tracking opens, clicks, and downstream revenue to find the best-performing flow.

Minimum 14 days with at least 1,000 impressions per variant. Shorter tests produce unreliable results due to day-of-week effects and traffic fluctuations. Visisto tells you when you have enough data — don't stop early.

Yes. Visisto connects experiment data to your Shopify or Stripe integration, so you can see which variant drives more purchases, higher average order value, and better customer lifetime value — not just open rates and clicks.
