LINE reservation message is here! Can be scheduled up to 1 year later, free trial method exposed

LINE is finally launching the "scheduled message" feature that many users have been waiting for. From now on, whether it's a work reminder, a birthday greeting, or a friend who doesn't want to disturb you late at night, you can write a message in advance and have it automatically sent at a designated time. LINE has disclosed the usage methods and restrictions in the official support center, and announced that it will gradually open a free trial through LINE Labs, and will later convert it to one of the paid features of LINE Premium.

LINE reservation messages can be set to be sent up to 1 year later

LINE previously announced the launch of a reservation messaging function at the "LINE CONVERGE 2026" annual press conference in Taiwan, and now the official has further announced the complete usage rules.

According to LINE's instructions, reservation messages are applicable to 1-on-1 chat rooms, multi-person chat rooms, group chat rooms and Keep notes. Currently, only text content is supported, with a maximum of 10,000 words per message. The reservation time can be set from 5 minutes to as far as 1 year later, and can be adjusted in units of minutes. Each LINE account can reserve up to 500 messages.

Not only new messages can be scheduled to be sent, but also old messages that have been sent or received in the chat room can be sent again at a designated time by long pressing, which is suitable for reminding friends of important matters. After the reservation message is sent, it will be displayed in the same way as a normal message. The other party will not see a special mark, nor will they receive a reminder that this is a reservation message.

Terms of use of reservation message function

● Target chat room: 1-on-1 chat room/multi-person chat room/group chat room/Keep notes

● Object message: text (up to 10,000 words)

● Appointment period: 5 minutes from the time when the operation is performed to up to 1 year later (can be set in 1-minute increments)

● Number of items that can be reserved: up to 500 items per account

How to use LINE reservation message? View the setting steps at once

Currently, if you want to use the reservation message function, you must turn on this function in "LINE Labs". After completing the settings, just enter the chat room and enter text, long press the original send button, select "Schedule Send", then specify the date and time, and press "Schedule Message". In addition, you can also find the reservation message function through the "+" menu at the bottom of the chat room.

LINE also provides a function to manage reservation messages. If you change your mind temporarily after the reservation is completed, don’t worry. You can enter the reservation message page, long press the specified message, and choose to edit the content, change the time, send or delete immediately, and even clear all unsent reservation messages in the chat room at once.

However, LINE also reminds you of several usage restrictions. First of all, if the reservation message function in LINE Labs is turned off, all previously set reservation messages will be deleted; if the message leaves the screen before the reservation setting is completed, the input content will not be automatically saved as a draft.

In addition, the scheduled transmission time is based on the set current time zone, so you need to pay special attention to the time difference when traveling abroad. If a new member joins the group, you may not be able to receive reservation messages. Officials recommend restarting LINE. If the other party has deleted their LINE account, they will not be able to schedule messages.

Why doesn’t the appointment message appear in LINE Labs?

It is worth noting that LINE stated that the "Reservation Message" function is gradually opening up. If you still can't find the "Reservation Message" option in LINE Labs, you need to wait patiently. "Reservation Message" is currently available to users for free through LINE Labs, but will later be converted into a function exclusive to LINE Premium members. The actual conversion time is still subject to subsequent announcements from LINE.
