A/B Testing

A/B testing compares two variants of a message, page, or workflow against the same audience to learn which one drives more conversions.

What is A/B testing?

A/B testing (split testing) is a controlled experiment where two variants — A and B — are shown to comparable audiences at the same time, and the winner is the one that hits the target metric (open, reply, demo booked, signup) at a statistically meaningful rate.

In B2B GTM, A/B tests usually run on subject lines, opening lines, CTAs, send times, sender identities, and landing page hero copy. Because outbound list sizes are smaller than consumer marketing, results are noisier, so teams typically test bigger swings (different angle entirely) rather than one-word tweaks.

Why it matters for outbound and GTM

Replaces opinion-based copy decisions with data
Compounds over a quarter — a 1.2x lift on reply rate across a 4-step sequence is materially more meeting requests
Surfaces which segments respond to which message — feeds back into ICP refinement

Common A/B tests in cold outreach

Subject line A vs. subject line B on the same send batch
Personalized first line (AI-generated) vs. generic opener
"Founder voice" sender vs. AE sender
Tuesday 9am vs. Thursday 2pm send window

How TexAu helps

Run two outreach sequences in parallel against split lists, pull reply and meeting-booked metrics into a single AI Column scorecard, and promote the winner. The list-builder + scheduler handle the split mechanics so you can focus on the hypothesis.
