All plans include a 7-day free trial. Starter costs $20 per user per month, Plus $35, Professional $50, and Enterprise uses Custom pricing; annual and monthly billing options are available.

AI output and automated actions can be inaccurate, biased, incomplete, unsafe, stale, or misleading, while services may process confidential, copyrighted, personal, voice, health, financial, educational, or regulated information. Check consent, retention, model-training, licenses, platform rules, renewal terms, accessibility, and security, and use qualified human review for high-impact work.

Cons

  • Granting an assistant inbox access exposes sensitive correspondence and metadata

  • A mistaken automation can archive; forward; label; or draft the wrong action
  • Voice-matched drafts may confidently reproduce an inappropriate tone
  • Users must review drafts before sending consequential messages
  • Bulk unsubscribe links can confirm an address to an untrustworthy sender
  • Plain-language rules can be ambiguous or conflict with one another
  • Self-hosting requires technical maintenance; security updates; and model configuration
  • Local Ollama models may produce weaker results on limited hardware
  • Starter pricing is significant for users with modest email volume
  • Higher tiers charge per user and increase team-wide cost
  • The Plus tier includes only two email accounts per user
  • Open source transparency does not automatically make a deployment secure
  • Calendar; CRM; Slack; and attachment integrations expand the permission surface
  • No-AI-training promises still require trust in each configured subprocessor
  • Organizations need retention; e-discovery; and approval controls before automation
