Which is right for me?

  • Your call volumes are low enough that 10s minimum billing and token surcharges aren't material
PeakSend AI logoChoose PeakSend if…
  • You run outbound sales campaigns and need to maximize contact and conversion rates
  • Your calls are revenue-generating — you want to optimize for results, not just the lowest rate

  • You run high-volume outbound campaigns where billing efficiency and DID health matter

FAQ

Frequently asked questions

PeakSend's voice AI costs $0.11-$0.16/min with no hidden fees. Retell's base rate starts at $0.115–$0.20/min, but token surcharges and lower latency surcharges can push the effective rate higher. Retell also bills a minimum of 10 seconds per call — which adds up fast for outbound sales campaigns with many short or unanswered calls.

Retell AI is a general-purpose voice AI platform designed for developers building custom voice applications. It does not include sales-specific features like objection-handling AI models, local presence dialing, DID reputation management, or intelligent follow-up cadences. PeakSend includes all of these as a built-in sales enhancement layer.

Retell charges $2/month per phone number but does not provide built-in DID management — you need to build your own number rotation, spam detection, and call routing. PeakSend charges $0.02/call for phone numbers (amortized from ~$1.40/mo per number) and $0.03/call for DID management, which includes automatic DID rotation, spam-likely detection, local presence dialing, intelligent follow-ups, and unlimited concurrency.

Most teams are up and running on PeakSend within a few days. Our team handles the migration, including setting up your sales scripts and configuring DID management. You don't need any engineering resources to get started.
