Sometimes a thumbs-up beats a full reply. PopIn messages support three lightweight responses: reactions, replies, and a pinned message.
At a glance
| Reaction | Reply | Pin | |
|---|---|---|---|
| Best for | Quick acknowledgement | Picking up an earlier message | The one bit of info the group needs handy |
| Visible to | Everyone in the chat | Everyone in the chat | Everyone, at the top of the chat |
| Available in 1:1 | Yes | Yes | No, group only |
Add a reaction
Long-press (mobile) or hover (web) on the message
A small action menu appears next to it.
Pick an emoji
Any emoji works, message reactions are free-form, not a fixed set. Tap your own again to remove it; you can add more than one.
Reply to a specific message
Long-press the message, then tap Reply
The original is quoted above yours so everyone sees the context.
Type your reply
Replies keep the chat linear with a clear back-reference, they don't spin off a separate thread.
Pin a message (group chats only)
A group can have one pinned message at a time, shown in a banner at the top. Pinning a new one replaces the old. Only the group's owner and admins can pin or unpin.
Long-press a message, then Pin
It moves to the banner at the top of the chat.
Unpin from the banner
Tap the pinned banner and unpin, or just pin a different message to replace it.
The pin is visible to everyone in the group, including people who join later. Use it for the one thing the group keeps needing (the address, the plan), not a private note.
