What is Claude in MunchReach?

Claude as the model behind AI personalization, and how it differs from the alternative.

Updated Sep 10, 2026 1 min read

Claude is one of the two AI providers MunchReach personalization can run on. The other is OpenAI. You choose one per campaign and connect your own key for it.

Available Claude models

  • Claude Haiku 4.5 — the default; fast and inexpensive, suited to volume generation
  • Claude Sonnet 4.5 — stronger writing, higher cost per lead
  • Claude Opus 4.1 — the most capable and the most expensive; reserve it for small, high-value lists

What Claude changes

Only the model that writes the personalization snippet. Every other part of the campaign — sequence, schedule, sending, suppression, analytics — is identical.

Important notes

Claude usage is billed to you by Anthropic against the key you connect. MunchReach does not resell it.
