Question 1

How can LocalBulkSMS send messages for 100% free?

Accepted Answer

LocalBulkSMS runs directly on your Mac and automates Apple Messages via native macOS scripting. When you send messages, they route through your existing mobile carrier plan or Apple iMessage network just like texting from your phone.

Question 2

What macOS permissions are required to use the app?

Accepted Answer

You only need two standard macOS permissions: Automation (to allow sending through Messages.app) and Full Disk Access (optional, only required if you want to browse your existing Messages history from inside the app).

Question 3

Can I send both green SMS and blue iMessages?

Accepted Answer

Yes! macOS Messages automatically routes messages to Apple devices via free blue iMessage, and routes to Android/non-Apple devices via green SMS using your iPhone Cellular Continuity.

Question 4

What sending speed is recommended to prevent carrier blocks?

Accepted Answer

We strongly recommend using the Random Jitter strategy (3s - 7s delay between texts). This mimics real human texting cadence and prevents carriers from flagging bulk bursts as automated spam.

Question 5

Is my contact list or message content stored in the cloud?

Accepted Answer

No. All campaigns, phone numbers, recipient logs, and templates are stored 100% locally in an auto-healing SQLite database on your Mac under ~/Library/Application Support/LocalBulkSMS/.

Question 6

Does it support dynamic custom tokens and CSV columns?

Accepted Answer

Yes. Any column in your CSV automatically becomes an interactive {{token}} with fallback support (e.g. {{first_name | valued customer}}).

Question 7

Do I download a different app after I pay?

Accepted Answer

No. It is the exact same app you already have installed. Buying Lifetime Pro does not give you a new installer — it removes the 3-campaign / 5-SMS-per-campaign limit from the app you already downloaded.

Question 8

What exactly happens right after I pay?

Accepted Answer

Stripe processes your card, you land back on this site with a confirmation screen, and within a minute or two an email arrives at the address you paid with, containing your license key (format: LOCALBULK-XXXX-XXXX-XXXX). Open the app, go to Settings → License, and enter that key plus your email to instantly unlock unlimited campaigns and messages — no reinstall, no restart required.

Question 9

What if I don't receive my license key, or something goes wrong?

Accepted Answer

Check spam/junk first — the email is sent from a transactional address and occasionally gets filtered. If it still hasn’t arrived after 15 minutes, or you hit any activation issue, email support@localbulksms.app with the address you paid with (or your Stripe receipt) and we’ll resend or fix the license manually.
