Using Video Testimonials in Cold Outreach Without Hurting Deliverability

The Core Issue

Embedding or attaching video/GIF testimonials in cold outreach significantly damages deliverability rates.

Recommended Approach: Two-Email Strategy

First email:

  1. Personal opener
  2. Social proof (one sentence maximum) — e.g., "helped X, Y, Z get 3–5x conversion improvements"
  3. Call-to-action

Follow-up email:

  • Include link to video testimonial only after they reply or engage

If You Must Include Video in First Email

Use a text-only link formatted as a case study instead of a video link.

What NOT to Do

  • ❌ Embed videos directly
  • ❌ Attach video files
  • ❌ Use GIF previews
