Do I need a Reddit API key?

No. FishOut collects Reddit itself; you add keywords, not credentials.

Can I limit it to certain subreddits?

Track keywords broadly and filter the inbox by subreddit. A narrower keyword such as your category plus “recommend” usually does more than a subreddit list.

How fast does a Reddit post reach Slack?

Reddit is checked hourly on every plan, and every 15 minutes for keywords you mark Fast on a paid plan.

Will it post comments as well as posts?

The alerts you see here are posts, which carry titles. A matching comment arrives without a title of its own today, so it is easiest to read in the FishOut inbox with its thread.

Reddit keyword alerts in Slack

Search “Reddit to Slack” and every result is an automation marketplace. Their recipes watch a subreddit, or a search, and post every new match. FishOut searches Reddit for your keywords across subreddits and reads each post before Slack sees it, so #brand-watch gets the threads where someone is asking for what you sell.

Checked hourly, or every 15 minutes for a Fast keyword on Plus and up. Slack alerts are on every plan.

[02] WHAT GETS FILTERED/ NOISE

What never reaches Slack

2 Reddit matches that go to Filtered instead, each with its reason.

Filtered · Reddit

r/AskRedditReddit

What is the most useless “acme” product you ever bought?

Filtered · Different meaning

Generic words in your brand name are everywhere on Reddit.

r/SaaSReddit

I built a shared inbox in a weekend, roast my landing page

Filtered · Below threshold

Self-promotion in your category — relevant, but rarely worth a reply.

[03] KEYWORDS THAT WORK HERE/ REDDIT

For Reddit, into Slack

More keyword shapes are on monitoring Reddit.

“looking for” + your category

The highest-intent Reddit posts describe a problem without naming a product. Your brand keyword never finds them.

Competitor + “alternative”, “price”, “renewal”

Reddit is where switching happens in public, usually with a number attached.

A floor of 70

Reddit is high-volume and high-intent. 70 keeps a team channel to posts worth a glance; send Reply now posts to a second channel at 90 if you want them faster.

Reply from your account, not from Slack

The alert links to FishOut, where a reply is drafted in your Voice and discloses who you are. You send it from your own Reddit account; FishOut never posts, which is what keeps accounts from being banned.

[05] A BUSY DAY/ DIGEST

When Reddit gets loud

A complaint thread about a competitor can produce a dozen new posts in a day across subreddits. The digest keeps them to one message per window, sorted by relevance, so the best one is on top.
