How ColdToYes works

Add ColdToYes to Claude or any assistant that supports MCP connectors. The first time, it asks a few questions about your business, who you sell to and how you like to write. That only happens once.

You do not need to learn a new app. The conversation is the interface.

Name people at a company, describe the kind of person you want to reach, or hand it a list. Small lists go out without any campaign setup at all.

ColdToYes looks up the right people and their work addresses, then verifies each address before anything is written. Bad addresses are dropped instead of bounced, which protects your inboxes.

• Bring your own data if you like. Paste a list, or connect the lead source you already pay for.
• Every address is checked before it can be sent to.

For each person it gathers what is public and relevant: their role, their company, recent posts, launches and hiring. It then writes one email for that one reader, in your voice.

You can read every email before it goes, change any of them by asking, or approve a whole batch at once.

• No templates. Two people at the same company get two different emails.
• Short by default. A clear reason to write and one simple ask.

Sends are spread thinly across your real-name inboxes and timed like a person working through their day. Instead of fixed daily caps, pacing earns volume from the replies an inbox gets.

ColdToYes does not add open-tracking pixels or redirect links, so your emails stay plain and look the way a normal email looks.

• Name-matched inboxes and domains can be bought in one step, already set up and started slowly.
• Bring your own inboxes if you already have them.

ColdToYes reads every reply. Interested people come back to you in the chat with the thread ready to answer. Out-of-office replies, wrong-person replies and not-now replies are handled, and anyone who says no is never emailed again.

Across all senders, ColdToYes learns which patterns earn replies: length, openings, timing, follow-up spacing and safe inbox growth. Those patterns make everyone's sending better.

Your leads, your lists, your copy and your conversations are never shared with anyone and never used to write someone else's emails.
