The real problem → the fix

Growth work is scattered.
PortKnot connects it.

Leads live in a spreadsheet.

One lead list, with context.

AI writes generic email.

Product-aware drafts.

Replies land in another inbox.

Reply Rescue stops follow-ups.

The next step disappears.

One pipeline, one next action.

How it works

Five steps. One workspace.

Find, approve, send, reply, and convert—without stitching five tools together.

20 seconds. Captions on screen. No audio.
Read the transcript
  1. Add leads. Paste, import, or capture.
  2. Approve. Edit or reject before sending.
  3. Send. Now or scheduled. Never twice.
  4. Reply stops it. Follow-ups stop; the thread opens.
  5. Convert. Move the conversation to a meeting and the next pipeline step.

Reply Rescue

The sequence stops when they reply.

Every reply opens with the full thread, the lead, and the next step. Follow-ups stop automatically.

FAQ

Questions, answered.

Does AI send automatically?

No. Every email is a draft until you approve it.

How do replies stop follow-ups?

When a lead replies, PortKnot automatically pauses the rest of the campaign for that specific lead and moves the conversation to your Reply Rescue inbox.

Can I use my own Resend?

Yes. You can connect your own Resend account to take full control of your sending reputation.

I only have one product. Is PortKnot for me?

Yes. One product is the default setup. You get the full workflow: find leads, AI drafts, approval, sending, Reply Rescue, and pipeline. Add another product only when you need one.

Can I run multiple products?

Yes. Each product has its own isolated ICP, campaigns, leads, and sender identity. Products on the same domain can share a verified sender; a product with a separate domain gets its own sender.

Does PortKnot learn from my campaigns?

Your product context, edits, replies, and meetings stay inside that product lane. That history is available to ground future drafts; nothing is borrowed from another product.

Is there a free trial?

Yes, you get a 7-day free trial with no credit card required.
