channel compare की सबसे common गलती - सिर्फ open rate। हाँ, WhatsApp ज़्यादा खुलता। हमेशा सस्ता नहीं। एक WhatsApp contact email से 40–80× महँगा हो सकता। कौन सा funnel stage pay back करता - यही लेख।
open rate = funnel entry, outcome नहीं। 90% open + zero conversion + expensive delivery हारता 20% open पर जहाँ opener buy करे।
सही order: contact cost → reply cost → deal cost।
opens: WhatsApp email से आगे। contact cost gap - huge।
| metric | ||
|---|---|---|
| open | 18–28% (B2C ~33%, B2B ~29%) | 60–90%+ |
| CTR/replies | 2–4% | 10–25% |
| 10k sends cost | ~$5–15 | ~$400–800 WABA |
| unit gap | - | 40–80× higher |
market benchmarks, fixed tariffs नहीं।
takeaway: WhatsApp noticeably better convert करे तभी pay back。
sleeping base reactivation. long inactive client messenger personal reply > promo email open। reactivation में response gap often contact cost gap cover。
operator example: 3000 sleeping; email 18% open, 2.1% click, 12 orders; WABA live question 84% read, 28% reply, 114 orders。practice observation。
hot lead nudge. form no buy - one WA question > email reminder chain; speed critical。
urgent offers - lock screen push vs inbox wait。
long content sequences - 10–12 emails few dollars; same cadence WA = irritation + reports。
scale low ticket - $20–50 product, $0.05–0.09 WABA session - margin tight; email large list cheap contact।
regular retention content - weekly digest classic email; WA rhythm → Quality Rating drop।
email: domain/IP gradual; spam folder。
WhatsApp WABA: 7-day audience reaction; red → templates blocked。both need clean list + relevant content; speed differs。
| scenario | best |
|---|---|
| long warm 10+ touches | |
| educational sequence | |
| large base low ticket | |
| sleeping reactivation | |
| hot lead nudge | |
| urgent deadline | |
| high ticket short cycle | |
| B2B long cycle | Email + WA |
Email warm → opened no reply → targeted WA question。
saves WA sessions; warm segment only。rule: WA where high reply probability; no-reply blasts cut QR。
«90% WA open - all marketing there» - digests irritate; reports degrade。
«email dead» - cheapest regular touch large base。
«no spam on WA» - account/template blocks。
one scenario - reactivation/nudge/warm-up - reply cost per channel (not send cost) calculate。
व्यावहारिक नियम:
open rate = attention, money नहीं। reply cost गिनो - सही channel खुद मिलेगा।
