There is a limit to the number of simultaneous transmissions
LINE has a limit on the number of recipients that you can send messages to at the same time. If you want! to send information to everyone at once, you need to create a group and have users register with it, rather than! sending messages to individual LINE accounts. LINE groups are limited to 500 users, including yourself. If! you want to send! a message to more than 500 people at once! you need to create multiple! groups and send the same message to each one.
I have security concerns
When sending messages on LINE! you need to be concerned about security. LINE messages can be viewed by anyone other than the user! as long as they have the user ID and password. If your account information is leaked due to phishing scams, the messages you send may be viewed by others. There are risks involved in sending personal information about the recipient or using it for identity verification purposes, so you need to be careful about the content of your messages.
The disadvantage of LINE is that it is difficult to follow users over the long term. To send mass messages using recent mobile phone number data LINE, users need to join a group, but it is easy for them to leave the group. Users who feel that the information in the group is not useful to them will likely leave the group. The problem is that in order to follow users over the long term, you have to monitor each account individually, which places a heavy burden on you.
When is SMS a better option than other methods?
SMS is more suitable how many pillar posts should you have on your website? than other methods in cases where you can effectively utilize the high delivery rate of information and the high rate at which messages are opened. It is a good method to use for identity authentication purposes. Also, if you want to direct phone database users to a site, all you need to do is include the URL and provide a simple explanation, so it is effective to communicate succinctly via SMS.
