# Email Signature A/B Testing

## Overview

A simple A/B test on the email signature job title can reveal whether displaying a "Business Development" title helps or hurts reply rates. The hypothesis is that recipients who immediately identify a sender as a salesperson may be less likely to engage, making the title a low-effort variable worth testing.

## The Hypothesis

When a prospect sees "Business Development" in an email signature, they immediately recognize it as a sales outreach. This framing may trigger a defensive response — lower engagement, faster dismissal — before the email content has a chance to land.

Removing the title (signing off as simply `Name, Company`) may reduce that friction and improve reply rates by letting the message speak for itself.

The counter-argument is that transparency about intent can itself build trust. This is an empirical question, not a theoretical one — hence the test.

## Test Design

| Variant | Signature Format | Hypothesis |
|---|---|---|
| **A (Control)** | `Jacob Jones, Business Development, Asymmetric` | Transparency signals professionalism |
| **B (Test)** | `Jacob Jones, Asymmetric` | Removing title reduces sales-pitch perception |

**Method:**
- Alternate variants across outreach days or batches (e.g., send Variant A on Monday, Variant B on Tuesday)
- Keep all other email variables constant: subject line, body copy, CTA, prospect segment
- Track reply rate as the primary metric; open rate as a secondary signal

**Sample size consideration:** Given expected reply rates of 2–5% on cold outreach, a meaningful difference will require a reasonably large send volume before drawing conclusions. Avoid interpreting early small-sample results as definitive.

## Implementation Notes

- This test requires no tooling beyond your existing email sequence — just two signature templates
- If your sequence tool supports conditional logic or contact tagging, you can segment cleanly; otherwise, manual alternation by day works
- Log which variant each contact received so results can be attributed correctly
