MODULR Marketplace · Claude plugin

Make Claude finally sound like you.

The Email Voice OS plugin calibrates Claude to your actual writing — your phrasing, your rhythm, your sources. No more editing every draft back to yourself.

  • Voice profile pulled from your past emails
  • Citation gate so Claude never invents stats or claims
  • Anti-AI phrase list tuned to your blind spots

What's inside the plugin

Three pieces, working together every time Claude drafts an email.

1

Voice profile

Claude reads your past emails and pulls the phrasing, openers, and rhythms that make your writing yours. Every draft is checked against that profile before it lands.

2

Citation gate

A check that blocks Claude from inventing stats, quotes, or claims. If a fact is not sourced, the draft does not ship.

3

Anti-AI phrase list

A custom list of the AI-isms that out your drafts as machine-written. Claude flags them before you ever see the copy.

What people are saying

Donald Devange

Marketing Agency Owner

We applied the MODULR method to a client's email and saw a 10% jump in open rates and a 6.5% lift in click rate.

Looking back at other successful emails, it's clear they unintentionally followed a version of the method. Your scoring tool is great.
