How to use Reddit for customer interviews
By MentionLeads · July 21, 2026 · 4 min read
In short: Recruit customer interview participants on Reddit by commenting helpful content in relevant subreddits, then inviting interested users to a direct message. Never post a recruitment link publicly. Use subreddits like r/SaaS, r/startups, and r/Entrepreneur — but always read the rules first. A 70% response rate is achievable if you offer value before asking.
Reddit is one of the best places to run customer interviews because users are already discussing their problems openly. But most founders get banned within a week. The mistake: posting a survey link or a "looking for interviewees" thread. Subreddit moderators treat that as spam. Instead, you need to recruit through genuine participation.
Which subreddits allow customer interview requests?
No subreddit explicitly allows "come interview me" posts. But some have weekly feedback or market research threads where you can ask. r/SaaS has a "Feedback" thread every week. r/startups has a "Share Your Startup" thread. r/Entrepreneur has a "Small Business Questions" thread. Post a short comment there: "Building a tool for [target audience]. Would love to chat with 3 founders for 15 minutes. DM me if you're open to it." That works because you're responding to the thread's purpose.
How to find the right users without posting publicly
Search for users who are actively complaining about the problem your product solves. Use Reddit's search with keywords like "I'm struggling with" or "anyone else having trouble with". For example, if you sell a CRM for freelancers, search r/freelance for "client management" and sort by new. Comment on their post with a helpful resource — not a pitch. Then after they reply, send a DM: "Hey, saw your post about client management. I'm working on a tool for that and would love your take in a 15-min call. No sales pitch, just your honest opinion. Does that work for you?" This approach yields a 50-70% response rate.
The exact DM template that gets replies
- Subject line: Keep it blank or use their username. Reddit DMs don't show a preview well, so the first line matters. - First line: Reference their specific post or comment. "Saw your comment in r/freelance about chasing invoices." - Second line: State your ask clearly. "I'm building an invoicing tool and want to interview 5 freelancers for 15 minutes. No pitch. Just your opinion." - Third line: Offer something in return. "As thanks, I'll share the aggregated findings with you." - Close: "Are you open to a quick call this week?" Never send the same template to more than 10 users per day. Reddit’s anti-spam system flags identical messages sent in bulk. Change one or two words each time.
How to avoid getting banned or shadowbanned
Reddit’s content policy bans self-promotion and spam. The key is to never post a link to your product or a survey in a public thread unless the subreddit has a designated thread for it. Even then, keep it to a comment, not a post. If you send DMs, space them out. Sending 50 identical DMs in an hour will get your account shadowbanned. Use a separate account for recruitment that has history — at least 100 karma and some genuine comments. Accounts created yesterday with 1 karma sending DMs get flagged immediately.

How to run the interview itself on Reddit
You can conduct the entire interview via Reddit DMs, but it's better to move to a voice or video call. DMs are asynchronous and low-pressure, but you lose tone and body language. Send a Calendly link (or just ask for a time) in the DM. If the user is hesitant, offer to do the interview right there in the chat. Keep it to 10-15 questions. Start with: "What's the biggest frustration with [problem area]?" Then dig into: "How do you handle it now?" and "What would a perfect solution look like?" Record the answers in a spreadsheet. After 10 interviews, you'll see patterns.
What to do with the interview data
Tag each pain point, current solution, and desired outcome. Look for the top 3 frustrations that appear in at least 7 out of 10 interviews. Those are your product priorities. Also note the language users use — copy those exact phrases for your landing page. Reddit interview data is raw and unfiltered, which makes it more reliable than survey responses.
Frequently asked questions
Can I post a link to a survey on Reddit?
Almost never. Most subreddits ban survey links outright unless you message the mods first and get explicit permission. Even then, expect low response rates. Surveys feel like spam. Interviews feel personal. Always choose DMs over public survey posts.
How many DMs should I send per day to avoid getting flagged?
Start with 5 per day from a new account. Increase to 10 after a week if no issues. Never send more than 20 identical DMs in a day. Reddit’s spam filter is aggressive — even 30 similar messages can trigger a shadowban. Rotate wording and vary recipients across different subreddits.
Should I pay Reddit users for interviews?
You don't have to, but offering a $10 Amazon gift card or a free month of your product increases response rates by 40%. Mention the incentive in your DM. If you can't pay, offer to share the results. Many users participate just to help or because they're curious about new tools.
