Session Rules

Session rules define how QuantixOne groups email messages into conversation threads. Configuring these correctly ensures replies land in the right conversation.

SettingDescription
Session TimeoutHow long a conversation stays "active" after the last message. After this period, a new email from the same contact starts a new conversation.
Reply ThreadingWhether replies to an email are grouped into the original thread using In-Reply-To headers.

Session rules section with timeout field and threading toggle Adjust session timeout and reply threading to control conversation grouping.

  • Session Timeout: 24–48 hours for most businesses. Set to 7 days for long sales cycles.
  • Reply Threading: Enable this for most use cases so replies stay in context.

Default Sender Settings

SettingDescription
Default From NameThe display name used when no specific sender identity is selected
Reply-To AddressAn optional address where replies are directed if different from the From address
Email FooterOptional text appended to every outgoing email (e.g., legal disclaimers or unsubscribe instructions)

Unsubscribe Handling

This is recommended for bulk emails and campaigns to comply with email regulations (CAN-SPAM, GDPR).
