TL;DR
50 subreddits sorted by niche: SaaS, ecommerce, startups, side projects, marketing, and more. Each with subscriber counts, promotion rules, and what actually gets traction. The best subreddits aren't the ones that "allow promotion" but the ones where your target audience asks for recommendations.
Or skip the manual research: Reppit AI ($25/mo) analyzes your URL and discovers relevant subreddits automatically.
How to Use This List
Not every subreddit on this list will work for your product. The goal is to find communities where your target customers hang out and discuss problems your product solves. A CRM tool doesn't just belong in r/CRM. It belongs in r/sales, r/smallbusiness, r/realestate, and r/consulting where salespeople discuss their workflow problems.
For each subreddit below, I've noted whether the community is friendly to product mentions, what kind of content performs, and what to avoid. For deeper subreddit research methodology, see our USP method guide.

The Rules That Apply Everywhere
Regardless of which subreddits you target, these rules apply to every community:
Read the rules before posting. Every subreddit has unique rules in the sidebar. Violating them gets your post removed and damages your CQS.
Comments > Posts. Replying to someone who's asking for help converts better than creating your own promotional post. Find the right conversations to join.
90/10 rule. For every 1 promotional comment, have 9 genuine interactions. This protects your account and builds trust.
Max 20 subreddits per account. Scale by adding more accounts, not more subreddits per account.
The best subreddit is the one where your customer is asking for help right now. That's what buying intent scoring finds.
Skip the Manual Research
This list gives you a starting point, but the subreddits that convert best for your specific product might not be on any list. They're the niche communities where your exact target audience discusses their exact problems.
Reppit AI ($25/mo) skips the manual research entirely. Enter your URL, and the AI discovers relevant subreddits and keywords automatically. Then it scans those subreddits daily, scores every conversation 0-100 by buying intent, and generates smart comment drafts. You post from your own account in the threads that matter most.
Frequently Asked Questions
What are the best subreddits for marketing?
Depends on your niche. SaaS: r/SaaS, r/startups, r/Entrepreneur. Ecommerce: r/ecommerce, r/shopify, r/dropship. Marketing tools: r/marketing, r/SEO, r/GrowthHacking. The best subreddit is wherever your customers are asking for solutions. See the full list above.
Can I promote my product on Reddit?
Yes, through helpful comments in recommendation threads. Most subreddits ban overt promotion but welcome genuine recommendations in context. The key is answering a question where your product is a real solution, not broadcasting ads.

Max 20 per account. Aim for a mix: 3-5 large (500K+), 10-12 mid-size (50K-500K), 5-7 niche (10K-50K). Scale with more accounts, not more subreddits per account.
