Text · $29/mo

Personal texts, sent from your own iPhone.

No third-party gateway. No 10DLC paperwork. No second number. You build your sphere, Knock watches for the right moment and drafts the note, you approve it — and your iPhone sends it from your real line. $0 per text.

2 Tag the moments

Mark the dates that start conversations.

Birthdays, closing anniversaries, home-iversaries, move-in dates. Knock fires on the right day — in your contact's own time zone — so the text lands when it means something.

  • Birthday, anniversary & closing-date signals
  • Time-zone aware, never at 3 a.m.
  • Set it once — it recurs every year

3 Draft in your voice

Templates that sound like you — not a robot.

Write it once, or start from a template and make it yours. Knock fills in first names and details so every text reads one-to-one. Your contacts never see a stiff "Hi {FirstName}".

  • Personal tokens filled in automatically
  • Preview exactly what each person receives
  • Your tone, your emoji, your sign-off

4 Approve once

One queue. Approve, tweak, or skip.

When a signal fires, the drafted text waits for your yes. Knock runs the full compliance check first and shows you the result, so every send is safe before it leaves.

  • Nothing sends without your explicit approve
  • Consent, blacklist, quiet hours & limit checked at send
  • Every decision logged and exportable

5 Your iPhone sends

A Shortcut you set up once does the sending.

During your workday, a Shortcut checks Knock for anything due and sends it — silently, from your real number. No gateway relays it, so it arrives as a normal blue or green bubble. Each message is marked sent the instant it goes, so it can never send twice.

  • Sends from your real iPhone line — $0 per text
  • Arrives as a normal iMessage/SMS, not "Likely Spam"
  • One message per check, marked sent immediately

6 The conversation is yours

Replies land in your normal Messages app.

When they text back, it goes straight to your iPhone — where the real relationship continues. Knock never sees the reply. (It literally can't.) You open the door; you walk through it.

  • Replies come to your own Messages, like always
  • Knock never reads incoming texts
  • STOP is honored automatically for compliance

Built to keep your number safe

Compliance isn't a setting you remember. It's checked every single send.

You're texting people who know you, at a human volume, from your own line — the lowest-risk shape there is. Knock keeps it that way with guardrails evaluated the second before each message leaves.

Consent on file
Every contact carries a consent flag. Opt-out (STOP) is honored automatically; opt-in is a deliberate action, never assumed.
Blacklist & blackout dates
Anyone you've flagged is never contacted. Blackout dates pause everything on days you choose — holidays, quiet periods, whatever you need.
Quiet hours & daily limit
Sends stay inside your contact's waking hours and comfortably under a daily cap that keeps personal numbers from being flagged.
