LinkedIn DM for social proof collection
Use LinkedIn direct messages instead of cold email to request testimonials and feedback, achieving 2.5x higher response rates thanks to built-in identity trust.
Why this can grow a startup
When asking for a favor like a testimonial or feedback, prospects need to see you are a real person. Cold email addresses carry no built-in credibility. LinkedIn's profile photo, work history, mutual connections, and company affiliation instantly lower the recipient's guard. The medium signals that you are a real professional making a genuine request rather than an automated outreach bot. This makes LinkedIn uniquely effective for trust-based asks where social proof matters more than scale.
Source-backed example
Indie hacker experiment documented in Wovly's 250+ case study analysis (March 2026) — personalized cold emails for testimonials hit only 19% response rate, but switching to LinkedIn DMs targeting the same user profiles achieved 50% response rate.

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.
