Why Voice Now (Even If You're SMS-First Today)
The wholesaler playbook of 2022-2024 was SMS-first. Cheap reach, decent reply rates, scaled fast.
The 2026 playbook is shifting because:
- Carrier filtering — 10DLC + carrier spam filters block more wholesale SMS
- State SMS regulations — TX, FL, OK, WV, and more adding A2P rules
- SMS fatigue — motivated sellers ignore unknown-number texts
- Reply rates dropping — 8-12% (2022) → 2-5% (2026)
- Voice AI quality crossed the threshold — indistinguishable from human in 2026
REI Reply was built for the SMS era. AgentSixx is built for what's next.
REI Reply + AgentSixx Stack

REI Reply: First-touch SMS to entire motivated seller list

↓
AgentSixx: Voice campaign to non-responders

When REI Reply Wins Alone
- You're brand-new to wholesaling, learning the funnel, and need cheap reach
- SMS is your defined channel and you don't want to add voice
- 10DLC + carrier compliance costs are fine for your margins
When AgentSixx Wins Alone
- You're past the SMS ceiling
- You want to consolidate your tech stack (one tool, not two)
- 10DLC compliance overhead isn't worth it for your volume
- You work probate / pre-foreclosure / absentee where voice converts higher
