The problem
The inbox is broken — and it is not your fault
Prospects have trained themselves to ignore cold emails. Not because they are all bad — because they all look the same. AI tools have made it impossible to tell a thoughtful, personalised message from a bulk sequence.
Better copy does not fix a trust problem. A stronger subject line does not fix a trust problem. The only thing that fixes a trust problem is proof.
Human Sender is the proof layer. One badge. One click. Your prospect knows you are real.

Quick thought on your Q3 pipeline
✓ Verified humanHow it works
Three steps. No change to your workflow.
01
Write your email normally
Use Gmail, Outlook, Salesloft, Outreach — whatever you are already using. Human Sender works alongside your existing tools, not instead of them.
02
Tap to sign it
One biometric tap in the Human Sender app generates a unique code tied to that exact email and recipient. Takes two seconds. Works on iPhone and Android.
03
Your prospect sees the badge
They click the link in your signature. They land on your verified profile. They see your name, your photo, and confirmation that a real human wrote this — specifically for them.
The badge
One line in your signature. Proof in every email you send.
Copy-paste it once into Gmail or Outlook. Every email you send from now on carries cryptographic proof that a real human wrote it.

Hi Sarah,
I noticed Markflow just announced your Series A — congratulations. I have been following your push into enterprise and had a specific thought on how Revly could help you close that segment faster. Worth a 20-minute call this week?
Best, Marcus

What your prospect sees
When they click your badge, they see four things.
A real human account
Liveness-verified at signup. Not a fake profile, not a bot account, not an AI persona.
This exact email
The code is bound to the email body via a cryptographic hash. Any edit breaks verification.
Written for you
The code is bound to the recipient. It cannot be copied from another email or reused.
Sent right now
Timestamped at the moment of signing. Not a recycled template from three months ago.
Before / After
Same email. One has proof.

What reps are saying
“I went from 4% reply rate to 11% in three weeks. My emails did not change — the badge did.”

Common questions
Everything reps ask before signing up
Does my prospect need an account to verify my email?
No. They just click the link. It opens a public page in any browser — no signup, no app, no friction. That is intentional: zero friction for the recipient means more of them actually click.
Does it work with Salesloft and Outreach sequences?
Yes. The Human Sender browser extension integrates with both. It injects a unique verification code into each email automatically as you send — no manual step.
How long does setup take?
Under 5 minutes. Create your account, complete a 10-second liveness check, copy one line into your Gmail or Outlook signature. Done. Free and unlimited from day one.
What does my prospect actually see when they click the badge?
A clean, public profile page with your name, photo, and a confirmation that you personally signed this exact email at this exact time — and that it has not been altered since. No account needed to view it.
Is it really free? What is the catch?
It is genuinely free and unlimited for individual reps while we grow. No credit card, no trial period, no hidden limit. We want real reps using it, seeing real results, and telling their team. That is the business model.
Nothing to lose
Your competitors' emails look like AI. Yours does not have to.
Free, unlimited, and ready in 5 minutes. Add it to half your emails this week and see the difference yourself.
