How to make overseas SMS marketing effective? This step must be completed before batch sending
In overseas marketing, SMS (text message) is still a very important channel:
- Very high open rate (nearly 100%)
- Fast reach
- Suitable for promotions, notifications, recalls
But the reality for many teams is:
👉 I sent a lot of text messages, but there were almost no conversions.
There is even:
👉 Failed to send, wasted cost, account is restricted
Why is your SMS marketing not effective?
Most of the problems are not actually about “content”, but about:
👉Data quality
1. The number is invalid
Common situations:
- Empty number
- error number
- User fills in random
👉 Failed to send SMS directly
2. Number format error
For example:
- Missing country code
- Local format is not converted to international format
👉 The system cannot recognize
3. Duplicate numbers
result:
- User receives multiple text messages
- Increased risk of complaints
4. Mixing of non-target country numbers
For example:
- You do the US market
- However, Indian and Brazilian numbers are mixed in the data.
👉 Waste of budget
