LinkedIn DMs for testimonial and social proof collection
Use LinkedIn direct messages instead of cold email when requesting testimonials or product feedback, achieving 2.5x higher response rates.
Why this can grow a startup
When asking for a favor rather than selling, prospects need to verify you are a real human with a real product. LinkedIn's built-in credibility signals — photo, work history, mutual connections — instantly lower the recipient's guard in a way a cold email address never can. The social context makes the request feel like a peer-to-peer conversation rather than a marketing ask, which is why response rates more than double compared to email for non-sales requests.
Source-backed example
Indie hacker experiment documented in Wovly's 250+ case study analysis — switched from personalized cold emails (19% response rate) to LinkedIn DMs targeting the same user profiles and achieved a 50% response rate for testimonial requests.

When to use it
Use this when LinkedIn is relevant to 0-100, 100-1K and you can run a bounded test with a free budget.
When not to use it
Do not use it as a substitute for customer evidence, a clear owner, or a measurable stop condition. Local platform rules and market behavior still need checking.
How to do it
- Choose one target segment and define the exact next action this tactic should prompt.
- Adapt the tactic to LinkedIn, using evidence from wovly.ai as context—not as a promised result.
- Record a baseline for: Target users from this channel who complete the intended first action. Set a guardrail that would make you pause the test.
- Run a narrow pilot and choose a test window that fits the normal decision or use cycle; do not scale before you have observed the full cycle.
- Compare the signal with its baseline. Scale only if the intended action improves without crossing the guardrail; otherwise revise one variable or stop and record what you learned.
