There is a mobile phone number, how to drain it?

If you have a large number of mobile phone numbers at hand, the most direct way is: SMS drainage.

However, SMS drainage is not necessarily good for the following reasons:

1. casting a net: SMS drainage is generally an act of casting a net. If the user number is obtained through a specific channel, it is recommended to send it to a user with high correlation for drainage.

2. Is the base large enough? The user base is high enough, and tens of thousands of mobile phone numbers are actually relatively small (individuals actually sent hundreds of thousands)

3. Is the interest high enough? : Is the short message lively and interesting, and is it interesting enough? Make users interested and users will understand.

4. Is the popularity high enough? Drainage websites or brands are not well-known, and users will only treat harassing text messages as spam messages. This operation is not recommended if the popularity is too small.

5. Date of texting: It is suggested to combine your drainage purpose in some festivals, such as double 1 1, double 12 e-commerce promotion, such as Women's Day on March 8, etc. Sending text messages on holidays will be more festive.

6. SMS sending time: suggested time is11:30 ~12: 30, 18:00~20:00. This time is mostly at rest or after work for dinner, which is more free.

7. Cost: You can find the relevant SMS platform and ask the customer service staff to bargain. The cost is usually a few cents, see if you can give a discount.

8. SMS will have an arrival rate. 100% will not send short messages to users due to customer shutdown, downtime, network and other reasons. If the arrival rate is too low, that is, the proportion of recipients is too small, drainage will have no effect.

9 .. SMS drainage is currently less effective in personal observation. Because the mobile phone system will have shielding software. Short messages are usually sent through a port. Besides yourself, others use this short message sending software. When a large number of people use the same software to send a large number of short message ports, more people may be dragged into anti-harassment short messages and cannot really show them to users.
