On Tuesday afternoon someone asked you a question in a client channel. It was a normal message in a busy thread. You saw it between two calls and meant to come back. By Wednesday there were sixty messages below it.
Email at least keeps the ask in a list. Slack is a river. A request there is not open or closed. It is just further up.
What Slack gives you
| Slack feature | What it finds | What it misses |
|---|---|---|
| Activity (mentions and threads) | Messages that @mention you, and replies in threads you are in | A question that did not mention you |
| Later (saved items) | Whatever you chose to save | Anything you did not save |
| Unreads | Messages you have not opened | Everything you read on your phone and did not answer |
| Search | Anything, if you know what to look for | You have to know what to look for |
Searches worth saving
Slack search takes modifiers. These three cover most of it:
@yourname after:2026-09-24for everywhere you were mentioned in the last week. Change the date.in:#client-channel after:2026-09-24to read back through one client channel for the week.from:@client-contactfor everything a specific person wrote.
And one habit: when you read a request you cannot answer now, save it to Later. That is Slack’s version of flagging an email.
Where the manual way stops
Every method above depends on one of two things: you were mentioned, or you remembered to save it. The request that hurts is the one where neither happened. You read it, it was not addressed to you by name, and the channel moved on.
Asking who is waiting on you
alfred_ is an AI personal assistant for work. Connect Slack and it reads the channels and DMs you are in, so a question someone asked you there does not slip.
# ops
Dana Kim
@Chris did the Acme invoice go out? Need it before Friday.

Anything in Slack waiting on me?
Delivered
Two things. Dana asked in #ops yesterday if the Acme invoice went out.
Luis asked for the signed SOW in a DM on Monday.
Remind me about Luis at 4
Delivered
Got it. I'll text you at 4:00 PM.
It answers with the message itself, who sent it and when, so you can go straight to it. And because it also reads your email, the same question covers both:
- “Is anyone waiting on an answer from me?” returns Slack and email together.
- “Catch me up on #harbor-facilities since Monday.”
- “What did the team decide about the walkthrough?”
What did the team decide about the Harbor walkthrough?

It moved to Thursday at 10. Dana confirmed it yesterday, and Luis said he'd bring the updated quote.

From found to handled
- “Remind me about Luis at 4” sets a reminder.
- “Add a to-do to send the signed SOW” puts it on your list, with a date if you give one.
- You answer in Slack yourself. alfred_ does not post as you.
What it does not do
It reads the channels and DMs you are in, not the whole workspace. It does not post, react or mark messages read. Plans start at $29.99 a month with a 7-day free trial; setup is on the Slack page.
