LESS GUESSWORK. MORE CONTROL.

Built for the whole conversation workflow.

↗

Three campaigns, independently

Separate drafts, variations, timing and progress. Pause one or stop all. Messages processes one send at a time through a shared queue.

＋

Your contacts, your way

Paste CSV or plain text, import a file, or enter one number. Save a searchable contact library if you want one. Only a phone number is required.

✓

Review with confidence

See complete personalized messages, invalid and shared numbers, previous contact history, and a downloadable will-send / will-skip report.

◷

Timing that you control

Set recipient delays and batch cooldowns. Optional business hours, recipient cooldowns and staged launches help reduce mistakes.

⊘

Shared do-not-contact list

Record opt-outs once and apply them across all three campaigns on this Mac. Enter or paste replies manually; incoming Messages are not monitored.

↺

Keep your place

Local checkpoints, exact-message history and CSV audit logs. Unfinished campaigns reopen paused; uncertain attempts never retry automatically.

FROM LIST TO REVIEW

Start small.
See exactly what happens.

Your account manages your plan. Your contacts, message content and campaign logs stay in the app’s local storage on your Mac.

Read how data is handled →
  1. Add your recipients

    Paste Alex, +14155550101, import a CSV/text file, or enter a single number.

  2. Write and preview

    Add variations and use {name} to personalize. Review the complete text and flagged numbers.

  3. Practice, then choose Live

    Dry Run ON sends nothing. Turn it OFF when ready, review your campaign and confirm live sending. Test messages to your own number are a separate, explicitly confirmed live action.

GOOD TO KNOW

A few answers before you download.

Does this send three messages at exactly the same time?

No. Up to three campaigns run independently, but share a queue that sends one recipient at a time through Messages. Each campaign has its own delays and controls.

Which phone number sends the messages?

The app uses the enabled Messages account available on your Mac. Set your sending identity in Messages settings and verify it with a test. The app does not rotate numbers or spoof identities.

Is my contact list uploaded to Firebase?

No. Firebase hosts this website and handles verified accounts, plan access and usage totals. Your contacts, messages, opt-outs and campaign logs stay on your Mac. Live messages go through Apple Messages and your carrier where applicable. Update checks and downloads use GitHub.

Can I use it without creating a contact library?

Yes. Paste a list or enter one phone number for a one-time campaign. Saving contacts is optional.

Will it avoid spam filtering or guarantee delivery?

No. Use expected, authorized communications and honor opt-outs. The app helps prevent mistakes; Apple and carriers control delivery and account restrictions. A sent status means Messages accepted the command.

How do I install or update it?

Download the Mac ZIP, double-click it, and drag the app to Applications. Quit the old app before replacing it. See the step-by-step guide.
