The alert is the easy part. What takes work is knowing that the mention was answered in the thread, reacted to or deleted, keeping a list of what is still open per person, and sending it at hours each person picked, in their timezone. Mention Reminder does all of that and clears each item on its own.
Mention ReminderComparison
Slack Workflow Builder, Zapier and Power Automate vs Mention Reminder
Workflow Builder, Zapier and Power Automate let you build your own chat alerts. An alert is only the first step: maintaining a list, recognising replies and scheduling reminders for each person require additional logic and maintenance.
⚖️ The short answer
Build an automation for a simple alert or to connect chat with another system. Use Mention Reminder for a ready-made list that reminds selected people and clears items after their replies.

What it is
What these automation tools can do with mentions
Slack Workflow Builder is included in paid Slack plans. A workflow can start when a message containing keywords you choose is posted, when an emoji reaction is used in a channel, on a schedule and in a few other ways, and then send messages or call connectors. There is no trigger for a specific person being mentioned.
Zapier connects Slack, Teams and Discord with other apps. Its Discord integration includes a New Mention trigger and a Send Direct Message action. Available events and capabilities depend on the integration and account. The free plan includes 100 tasks a month; paid plans offer higher limits and more advanced automations.
Power Automate’s Teams trigger When I’m @mentioned applies to the connected user and a selected chat or channel. Reading replies, maintaining a list and clearing reminders require extra logic. These can be built, but are not ready-made features of a simple mention alert.

When it is enough
When building it yourself is enough
- You want an alert for one busy channel or one keyword, not reminders for the whole team.
- Someone on the team enjoys building flows and will keep them running.
- What you need to be reminded about is not a mention at all, such as a form submission or a new ticket.
When to add Mention Reminder
When to add Mention Reminder
- You want each reminder to close itself on a reply, a reaction or a deleted message, without building that logic.
- You want every covered person reminded at their own hours, in their own timezone, from one install.
- You would rather not pay per task or run every time somebody is mentioned.
- Your team spans Slack, Teams and Discord and you want one inbox per person, not three sets of flows.
🤝 Using both
Using both
Keep your automations for what they are good at: routing requests, posting summaries, connecting chat to other systems. Let Mention Reminder handle the @mentions themselves, so nobody has to maintain a flow that watches for them. The two do not interfere: the only thing Mention Reminder adds to a message is a 🔔 reaction, and if a workflow of yours reacts to emoji, leave the bell out of its trigger.
The When I’m @mentioned trigger applies to the account used in the connection, so it does not cover every colleague by itself. A wider solution needs additional design. In Mention Reminder, the admin chooses people in the panel and the bot maintains their reminders.
It depends on usage, actions and services. Zapier counts tasks, so more activity can increase consumption. Mention Reminder charges per person with reminders enabled: Starter is free for up to 5 people, and Team costs $3 monthly billed quarterly or $2.50 billed annually per person.
No. Mention Reminder is a Slack app and works on free Slack workspaces too, as well as in Microsoft Teams and Discord.
