Reddit alerts for the keywords you choose

Updated 31 August 2026

Can you set up Reddit alerts?

Not for keywords, from Reddit itself. Reddit's own notifications are about your account and the communities you have joined: replies to your posts, activity in a subreddit you follow. There is no setting that says tell me whenever anyone anywhere on Reddit writes this word.

That is what a keyword alert tool is for. You give it the terms and the communities; it reads what is posted there and tells you when one of your terms shows up.

The problem with keyword alerts

A keyword alert is cheap to send and expensive to read. Any term that comes up often produces a stream of notifications, most of them somebody using the phrase in passing, a resale listing or a job post. You still have to open each one to find out which is which.

The two usual fixes both cost you something. Narrow the keyword until it stops firing and you lose the threads you wanted. Cap how many alerts a keyword may send in a day and the one that mattered might have been the eleventh.

Redwatcher scores the match first, then decides whether it is worth sending.

What a scored alert contains

Every match is scored from 0 to 100 for relevance in context, and the alert carries the reasons behind the number. Someone weighing up two products in your category and someone selling one second-hand both mention the same brand. The score tells them apart, and shows its reasoning.

You set the bar. What clears it is sent. What does not stays in the app and is counted, so nothing disappears without you being able to see it.

When a score is wrong, one click corrects it. The correction is written into your scoring rules and applied to every later match, so the alerts get closer to what you want as you use them.

Where a Reddit alert can go

Email, Slack, Telegram and a signed webhook, on every plan. Slack and Telegram install in one click, and every channel has a test button that sends a real message, so you know it works before the first real alert.

The webhook is signed and carries the thread, the score and the reasons, which is enough to route an alert into Zapier, Make or your own system without a second lookup.

How quickly an alert arrives

Every tracked subreddit is checked around the clock, multiple times every hour, on every plan. Median freshness is about 15 minutes.

Every plan is checked on the same schedule. What changes with the size is how many keywords and subreddits you may track.

No cap on what reaches you

There is no per-keyword daily limit and no monthly quota on matches. When a term has a busy week you get all of it, and the score you set decides how much of it reaches you.

What to alert on

• Your brand and its spellings. However people actually write it, including the ways they get it wrong.
• Your competitors. Every competitor you track counts as one keyword against your allowance.
• The problem you solve. The phrases people use when they are choosing something, before they know your name.

Setup will propose all three from your website, along with the subreddits where they come up, and each suggested subreddit is checked against Reddit as you accept it.

What it costs

Price is per project, and each project is bought at a size.

Larger volumes are priced case by case. Scoring, all four alert channels and unlimited team members are on every size; only the two allowances change. Seven-day trial, no card.

Reddit alerts: questions people ask

Can you set up Reddit alerts for a keyword?

Not through Reddit. Its notifications cover your own account and the communities you follow, not words appearing anywhere on the site. A monitoring tool does that part: you name the terms and the subreddits, and it tells you when they meet.

How do I get alerted when someone posts on Reddit?

Name the subreddits you want watched and the terms you want to hear about. Redwatcher reads posts and comments in those subreddits around the clock, multiple times every hour, and alerts you by email, Slack, Telegram or webhook when a match clears the score you set.

How can I monitor keywords on Reddit?

Score the matches before they are sent, instead of narrowing the keyword until it stops firing. Every match is scored 0 to 100 in context, you set the bar, and anything below it is kept and counted in the app instead of mailed to you.

How to set up keyword alerts?

You need three things: the words, the places, and the bar. Put in your brand and its spellings, your competitors and the phrases people use for the problem you solve. Name the subreddits to watch. Then set the score a match has to beat before it interrupts you. Setup proposes the first two from your website.

Is there a Reddit alert app available?

Redwatcher runs in the browser and sends alerts to email, Slack, Telegram or a webhook, so they arrive where you already work and not in one more app to check. Phone apps exist for following subreddits, but they notify you about communities you joined, not about a word appearing anywhere.

What do Reddit alerts cost?

$29 a month for 25 keywords and 25 subreddits, $49 for 50 and 50, and $89 for 100 and 100. Scoring, all four destinations and unlimited team members are on every one. Seven days free, no card.

Is Reddit keyword monitoring the same as Reddit keyword alerts?

They are two halves of the same job. Monitoring is the reading: every post and comment in the subreddits you named, checked around the clock. The alert is what comes out of it once a match has been scored and cleared your bar.

Do Reddit alerts cover comments?

Both posts and comments. Most of the conversation you could answer happens down in the comments, so alerting on posts alone leaves most of it unseen.

How fast do the alerts arrive?

Median freshness is about 15 minutes, and every plan is checked on the same schedule.
