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:

  1. Carrier filtering — 10DLC + carrier spam filters block more wholesale SMS
  2. State SMS regulations — TX, FL, OK, WV, and more adding A2P rules
  3. SMS fatigue — motivated sellers ignore unknown-number texts
  4. Reply rates dropping — 8-12% (2022) → 2-5% (2026)
  5. 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

If you're already on REI Reply, the stack is:

REI Reply: First-touch SMS to entire motivated seller list
  ↓
SMS non-responders after 5-7 days
  ↓
AgentSixx: Voice campaign to non-responders
  ↓
Voice conversations → warm transfers to you → contracts

The same list produces 3-5x more closed deals.


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

Why Investors Switch From REI Reply

"Consolidated my stack — was paying REI Reply for SMS, Mojo for dialing, and an ISA for warm transfers. AgentSixx does all three. Saved $4,200/mo and increased closings." — [Wholesaler, AZ]
