I don't believe Slack does it. I think in Slack/GitHub/etc., the point of emoji reactions (vs. just sending a reply with an emoji in the reply) is to respond without triggering a notification to the other participants on the thread.

I guess I can see a case for wanting a notification about reactions to messages you yourself sent, though (but not have those notifications go to other folks). I'd like to get more feedback on this question and the use cases involved; I can imagine wanting an easy way to narrow to your messages with emoji reactions on them being something folks want.

If Zulip is a chat tool for developers, I don't think the author would like to be notified about the reactions but if yeah a checkbox could be added to streams setting to enable or disable reaction notification

So I'd say that adding an extra feature would increase the number of features Zulip supports, therefore improving the product. On my opinion this may be be implemented using a checkbox

There a lot of product managers that would argue that sometimes adding new features can make a product worse :).

If someone wants to work on this direction, I'd probably started with adding a narrow, since I think that would be fairly easy and useful. Maybe has:reaction as the keywords?

@timabbott
We would like to introduce emoji as a response to a request in my teamwork environment.
For example:
:thumbs up: to inform the initiator that you "understand the message", "like the idea", or "take the action".
:check mark: to inform the initiator that you "finish the request" or "terminate the discussion".

The notification on emoji would make the communication simpler and more efficient.
Does this kind of usage/idea make sense to you?
Thanks.

This issues looks like related to #14869.

Like @wolfsonchuang suggested:
I'd like to have a feature that the first emoji reaction should trigger a notification (limit to first, cause in streams there could be really many emoji reactions.

Cause in my zulip at work the emoji is always used when a yes/no question is raised.

I asked for something like this at https://chat.zulip.org/#narrow/stream/137-feedback/topic/I.20want.20to.20be.20able.20to.20see.20all.20reactions

For myself, the important part isn't notification so much as being able to see all the reactions in aggregate. This is how Slack does it (in response to @timabbott's comment above.)

My users have requested this too. An opt in feature to be able to get notified when someone reacts to your post would be great. Many people post something in our group, get lots of "likes" but the original poster never gets notified because there was no need to respond anything but a thumbs up or other confirming emoji..

Yes, this is needed. Otherwise, authors don't know people reacted to their messages.

For reference, this is what Slack does:

Tim wrote above (back in 2017):

Yeah, I think that last is the key point. A reaction still doesn't bump the thread for everyone else, but it gives feedback for the one person who sent the message you're reacting to.

I often feel like I miss signals from reactions — I happen across some thread a while later, and only then see that people reacted to one of my messages. Conversely, sometimes I find myself manually going and looking back at a thread to see if there are reactions. This feature would make sure those signals don't get dropped.

Fully agree... much needed!

Hello!
This question is very relevant now. Please add this functionality. As previously discussed, push notifications should only come to the author of the message.

Closing in favor of two specific issues for implementing this feature request: #27327, #27328. Any comments on the relative importance of these two pieces would be very helpful!

I have the same situation that has been written about before. I have to go to a topic to see how people reacted to my suggestion or idea. The fact that I am left in the dark makes me tense.
