Know who opens, clicks, or deletes. Before you send.
One email, three roles, three readers. Email Campaign Simulation runs every variant through the full inbox-to-page chain, so you know who opens, clicks, replies, or deletes, before you send.
How it works.
A three-stage chain, run across every variant and every role.
The inbox
Subject and preheader only. Open or ignore.
The body
Read against the promise. Click, reply, or abandon.
The destination
The page lands the promise. Convert or bounce.
Rank the matrix
Every variant, every role, scored. Winners surface.
Three ways it fails. Three fixes.
Each one is invisible until after launch. WhyUser catches all three before the spend.
The inbox attention tax
120+ emails a day. The subject gets two seconds. Automated? Relevant? Gone.
The subject-body break
The subject earns the open. The body opens with “Hope you’re well!” Promise shattered.
Optimized for none
One email to the VP, the architect, and the engineer wins for none of them.
The Per-Persona Winner, and everything around it.
Weeks of A/B cycles and subject-line guessing. Gone.
| Eng | CFO | Sec | |
|---|---|---|---|
| A · “Cut rollback 60%” | win | miss | weak |
| B · “Reduce TCO” | weak | win | weak |
| C · “Quick question” | miss | miss | miss |
