Before You Send

Tips for better results

The platform gets you the numbers. These habits get you the replies.

⚖️

Get consent before sending

The Australian Spam Act 2003 requires opt-in for commercial messages. Cold SMS from purchased lists has legal risk. Read our compliance guide.

✅

Verify numbers before importing

Dead numbers waste SMS credits and hurt your sender reputation. Use a platform with real-time verification, or run your list through a number checker before you import.

🧪

Start with a small test batch

Send to 50 to 100 contacts first. Check delivery rates, replies, and any opt-outs before you scale to the full list. It saves credits and tells you what's working.

✏️

Personalise your messages

"Hey [first_name]" gets around 40% more replies than generic blasts. Monster SMS supports dynamic fields so you can personalise at scale without extra work.

🤖

Use AI agents to handle replies

When leads respond, they're warm. Monster SMS AI agents can reply instantly, qualify the lead, and book a call, 24/7. Don't let a hot lead go cold while you're asleep.

📊

Track, then optimise

Monitor delivery rates, reply rates, and conversions in your Monster SMS dashboard. The data tells you which list segments, messages, and send times actually work.

Your list is ready. Now send it.
