For agencies

Win clients who never answer cold email.

Send prospective clients a letter that shows you did the homework, and know the moment they read it.

Pitch with an idea.

A teardown, a sharp observation or a quick win for their brand, in a letter they actually open.

Know who is warm.

A broken seal tells you which prospects read your pitch, so you follow up with them first.

Discovery calls, booked.

Prospects book from the letter. The call lands on your calendar and in your CRM.

The pitch

Show them you did the homework. A real idea beats a capabilities deck.

Point out what you would change on their site, their brand or their campaigns, and offer to walk them through it.

Sam,

I spent an hour on the Halyard site this weekend. The product has grown up, but the website still sells the version from three years ago.

I put together a one page teardown with the three changes we would make first, starting with the homepage. Worth 20 minutes to walk through it?
