Social proof

Social proof is the use of testimonials, reviews, customer numbers and real cases to reduce hesitation in the purchasing decision. On WhatsApp, social proof delivered at the right time speeds up closing by 30-50%.

Types of social proof that work

• Video testimonial — 30-60s of the real customer speaking the result. Greater convincing power.
• Quote in text + photo — short quote + customer photo + name + company. Easy to send via WhatsApp.
• Aggregated numbers — "552 users on the Chrome Web Store"; "98% satisfaction"; "Active operation for 6 years".
• Customer logos — image grouping recognizable logos from the niche.
• Public Reviews — print of the note on Google Reviews, G2, Capterra, Reclame Aqui.
• Case Studies — link to detailed PDF with before/after.

When to send social proof on WhatsApp

1. Moment of objection — client said “I think it’s expensive” → send client case with quick ROI.
2. Comparison with competitor — client said "I'm looking at option X" → send a quote from someone who migrated from X to you.
3. Hesitation when closing — customer stopped responding → send video testimony.
4. Onboarding — new client receives cases from others in the same segment to see what is possible.

Good practices

• Always with authorization from the original customer — ask in writing before using name/photo.
• Match with the prospect’s profile — hospital case for hospital, not for dentist. Increases identification.
• Specific, not generic — "Reduced no-shows by 73% in 60 days" wins "Great tool!".
• Don't overdo it — sends 1 test per moment, not 10. Spam.

Social proof in quick message

Set up 3-5 social proofs as quick messages on Zapext. The attendant chooses the most relevant one at the time of the objection and sends it in 1 click. Reduces closing time and increases consistency.
