LinkedIn DMs for social proof collection
Use LinkedIn direct messages instead of cold email when requesting testimonials or product feedback, leveraging profile credibility for 2.5x higher response rates.
Why this can grow a startup
When you ask for a favor (testimonial, feedback, or case study participation), prospects need to know you are a real person. LinkedIn's built-in credibility signals — photo, work history, mutual connections — instantly lower the prospect's guard in ways a cold email address never can. The 2.5x improvement in response rate means founders can build a social proof library dramatically faster, which compounds conversion improvements across every other channel.

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.
