Email Copilot

Limits, Credits and Retention

Last updated: July 14, 2026

Email Copilot operations consume message credits from your monthly quota.

Message credit usage

  • Suggest Response - the credit cost depends on the AI model and context size selected for your chatbot
  • Translate incoming email - 1 credit per translation
  • Translate response draft - 1 credit per translation
  • Sending emails - does not cost message credits

The credit cost tooltip appears when you hover over the question mark icon next to the Suggest Response button.

Limits and quotas

  • Maximum emails stored per account: 500
  • Default email retention: 1 day
  • Maximum email retention: 10 days
  • Daily send limit: 1 - 300 (configurable, default 100)
  • Maximum recipients per email (To + Cc + Bcc): 20
  • Maximum attachment size per email: 10 MB total
  • Maximum email body size: 2 MB
  • Trash folder capacity: 50 emails
  • Email fetch interval: every 30 minutes (automatic)

Email retention and cleanup

Emails are automatically cleaned up based on two rules:

  1. Age-based cleanup - emails older than the configured retention period are deleted nightly. Default is 1 day, adjustable from 1 to 10 days
  2. Count-based cleanup - if the inbox exceeds 500 emails, the oldest are removed regardless of age

Adjusting the retention period

Select your chatbot and navigate to Danger Zone, then scroll to the Email Messages section. Use the slider to set the retention period between 1 and 10 days, then click Save Changes.
