Best Subreddits to Promote a Marketing Tool

Selling a marketing tool to marketers on Reddit is playing on hard mode: the audience knows every trick and the mods have seen every pitch. Value-first participation is the only lane that survives.

13 communities, 6.5M combined members, ranked by each subreddit's own rules.

Where promotion is tolerated (with care)

These communities allow product mentions under their stated conditions. Read the linked rules before posting, the conditions are specific.

Participate first, promote rarely

Promotion here is heavily restricted or the rules leave it unstated. Build a presence by being useful; an occasional relevant mention may survive, a pitch will not.

r/socialmedia 2.1M members · ~12 posts/day

Strictly limited

You should not promote your product in r/socialmedia unless your post clearly fits the subreddit’s professional discussion purpose and does not function as unsolicited promotion. Rule 6 says, "please refrain from unsolicited self-promotion or driving traffic to personal channels," and the submit page warns, "SPAM/Advertising/Selling Accounts = BAN." If you share links, Rule 4 also requires your own commentary, context, or analysis.

Strictly limited

You cannot directly promote your product as an offer or service post here. The rules say, "This place is not for offering services or looking for a job," and "Link submissions to blogs, articles or videos are not allowed," but they do allow sharing your own content if you make it a text post, include the article or a summary, and put the link at the end.

r/AskMarketing 157.9K members · ~23 posts/day

Strictly limited

Don't promote here

These communities ban promotion outright. Still worth being present as a genuine participant: buyers read these threads, and so do the AI models answering their questions.

Promotion banned

Rankings come from each subreddit's own published rules (quoted on the linked pages), not opinion. And whatever the rules allow on paper, the removal pattern everywhere is the same: batches of similar comments, reused wording, and necro-posting die. We measured it: 80% of bought Reddit comments were removed within a month.
