How Knock turns your iPhone into a follow-up engine.

No third-party SMS gateway. No A2P 10DLC registration. No new number. Your iPhone sends the texts itself, from your real line, on the schedule you set.

  1. 1

    You build your sphere in Knock.

    Add contacts one at a time, paste them in, or upload later. Tag birthdays, closing dates, and home anniversaries — Knock will fire on the right day automatically.

  2. 2

    You schedule signals.

    Pick a contact (or a sphere), pick a template (or write fresh), pick a time. Knock queues it. Variables like {first_name} get filled in so every text feels one-to-one.

  3. 3

    Your iPhone does the rest.

    A Shortcut you set up once polls Knock during your work day. When a message is due, your iPhone sends it — silently, from your real number. Replies come back to your normal Messages app.

Why this works when SMS marketing platforms fail.

Mass-blast services route through carrier shortcodes. Recipients see "Likely Spam" or it lands in promotions. Knock sends from you.

Your real number

Green bubbles, blue bubbles, RCS — exactly as your relationship would normally text. The recipient sees "Shaune" because you're already in their phone.

No carrier registration

You're not a brand sending bulk SMS. You're you, texting people who know you. No 10DLC paperwork, no campaign approvals.

Carrier-friendly volume

Daily rate limit, quiet hours, blackout dates, and consent capture — built in. Stay below the threshold that gets personal phones throttled.

Compliance, baked in

Every contact has a consent checkbox. Every send respects your blacklist, blackout dates, quiet hours, and rate limit. Audit log of every decision.

Replies stay private

When they text back, Knock doesn't see it. Your existing Messages app handles the conversation — exactly like it would today.

You're never locked in

The Shortcut polls a public endpoint. Your contacts and messages are yours. Export anytime; cancel anytime.
