iMessage is built for real conversations with real people, not for mass marketing blasts. Stay personal, stay under the limits, and Apple will treat your account as a genuine user.
Apple doesn’t publish exact limits, but if you act like a spammer, they will block you. The single most important rule: keep your messaging under 50 unique contacts per day.

​
Why This Matters​

Apple has sophisticated systems to detect and block accounts that behave like spam. Unlike a marketing platform, iMessage routes through your personal Apple ID and your own devices, so the consequences land directly on your account:
  • Temporary block - iMessage stops working for 24 to 48 hours.
  • Permanent ban - Apple can permanently bar your Apple ID from using iMessage.
  • Messages stuck - Texts sit unsent or silently fail to deliver.
  • Green-bubble downgrade - Messages stop sending as iMessage and fall back to SMS.
This tool is built for personal follow-ups, not for replacing your bulk email software.

​
Daily Sending Limits​

The golden rule is 50 unique contacts per day. “Unique contacts” means new people, replying back and forth within an existing conversation is fine and does not count against you the same way.
Account AgeSafe Daily Limit (new contacts)
Brand-new Apple ID10-15 per day
1-2 weeks old20-30 per day
Warmed-up & establishedUp to 50 per day
These are conservative, safe ranges, not hard numbers Apple guarantees. When in doubt, send less and space messages out across the day rather than in one burst.

​
Warm Up a New Apple ID​

A brand-new Apple ID has no reputation. Just like a new phone number, you need to build trust gradually before sending at full volume.
1

Days 1-3: Start small

Send to only 10-15 new contacts per day. Have genuine, two-way conversations, your goal is replies, not volume.
2

Days 4-7: Build up

Increase to 20-30 new contacts per day if everything is sending normally and you’re getting replies.
3

Week 2 onward: Full operation

Scale up to your steady-state cap of 50 unique contacts per day. Keep conversations natural.
Getting replies is the strongest signal to Apple that you’re a real person. Two-way conversations build your reputation faster than anything else.

Best Practices​

​
Do​

  • Keep it under 50 unique contacts per day.
  • Personalize every message, vary your wording instead of copy-pasting.
  • Have real, two-way conversations.
  • Space your messages out across the day.
  • Use it for warm leads and people who expect to hear from you.

​
Don’t​

  • Send the exact same copy-pasted text to everyone.
  • Blast a purchased list of cold numbers.
  • Send a massive coupon or promo to your entire database at once.
  • Run unattended bots with no human supervision.
  • Exceed your daily limit “just this once.”

​
What to Use iMessage For​

Good Uses

  • Following up after a lead fills out a form
  • VIP support - a direct line for your best clients
  • Appointment reminders people actually read
  • Team chat with staff who use iPhones

Avoid

  • Cold-texting a list of 1,000 bought numbers
  • Mass coupon blasts to your whole database
  • Fully automated bots with no oversight
  • Identical messages sent at scale

​
Keep Your Mac & Connection Healthy​

A reliable connection keeps your account in good standing and your messages flowing:
  • Keep your Mac online and awake at all times (a Cloud Mac is ideal for 24/7 uptime).
  • Make sure the iMessage Sync app stays open and running.
  • Disable sleep and Power Nap so the Mac never drops offline mid-send.
  • Maintain a stable internet connection on both the Mac and iPhone.
Frequent disconnects and re-connects can look suspicious. A stable, always-on setup is both more reliable and safer for your account.

​
Account Security​

Protect the Apple ID and the device that power your iMessage channel:
  • Put a strong password on your Mac.
  • Turn on Two-Factor Authentication (2FA) for your Apple ID.
  • Never share your Activation Code with anyone.
  • Use a dedicated Apple ID for business messaging if possible, kept separate from your personal account.

​
Data & Privacy​

The app on your Mac acts as a secure bridge between iMessage and your CRM. How we protect you:
  • Messages use Apple’s native end-to-end encryption in transit.
  • Your messages are processed locally on your Mac first.
  • We do not permanently store your conversation histories on the servers after they’re delivered to your CRM.

​
If Your Account Gets Blocked​

If you’ve sent too many messages and iMessage stops working:
1
Stop all workflows immediately so you don’t make it worse.
2
Wait 24 to 48 hours for a temporary block to lift on its own.
3
Lower your daily limits before resuming so it doesn’t happen again, and warm back up gradually.
4
If your account doesn’t unlock after a few days, contact Apple Support and tell them your iMessage stopped working.
Repeated violations can lead to a permanent ban of your Apple ID’s access to iMessage. Treat the daily limit as a hard ceiling, not a target.
