Note: Don't spam communities, instead ask for feedback on your business! You should not just post a link or hard-sell your product. Instead, provide valuable content, and then you can add your CTA / lead magnet. And that’s where message templates come into picture

A reality check on "promote here" lists
Communities like r/RoastMyStartup, r/Promotereddit, and r/Freepromote are useful for one thing: a low-risk place to practice and get early feedback without annoying anyone. But be honest about what they are — they're mostly other founders promoting to each other. Real customers rarely browse them. Treat them as a sandbox, not a growth channel.
The channel that actually moves the needle
Your best subreddit is almost never one with "startup" or "promote" in the name. It's the niche community where your specific buyer already discusses the problem you solve — r/juststart for a bootstrapped SEO tool, r/FulfillmentByAmazon for an Amazon-seller app, r/msp for IT-provider software. The self-promo bar is higher there, but so is the value of landing well.
How to vet a subreddit before you commit
- Subscriber count is a vanity metric. A 20k-member sub with 50 daily active commenters beats a 2M-member sub where nothing gets traction.
- Check the self-promo ratio in the rules — many state an explicit "9:1" or "no links in posts" policy.
- Look for founders who survived. Search the sub for "I built" or "I made" and see whether those posts have positive scores or removal notices.
Run any candidate through the Subreddit Finder for live activity and self-promo tolerance, and check a specific draft against its rules with the Rules Checker. Related reading: best subreddits for SaaS founders.
