Title: Allow User-Level and Account-Level Default Reply Channel (e.g., Always Default to Email) Description: In the current Conversations UI, the reply composer defaults to SMS, WhatsApp, or Email based solely on the last inbound message. This behavior cannot be overridden by the user and there is no setting—agency-wide, account-wide, or user-level—to make Email the default reply channel. This creates friction, inconsistency across teams, and increases the risk of replying on the wrong channel. Requested Enhancement: Add a configurable setting that allows users and account administrators to define a default reply channel for Conversations. For example: Proposed Settings: User-Level Default -- Default Reply Channel: Email / SMS / WhatsApp -- Optional toggle: “Always default to this channel (ignore auto-detect)” Sub-Account-Level Default -- Apply a default channel for the entire team -- Override per user if needed Agency-Level Default Enforce channel preferences across all sub-accounts Optional Safeguard Setting: “Warn before sending SMS when Email is available” This prevents accidental SMS replies that incur cost or break compliance workflows. Why This Matters Operational Efficiency Teams that primarily communicate through Email must constantly switch the composer from SMS to Email—sometimes dozens or hundreds of times per day. Prevents Accidental SMS Replies A contact may have previously texted once, and the system silently defaults to SMS—even when the user intended to send Email. This results in: -- Unintended SMS charges -- Mixed communication channels -- A2P compliance issues Consistency Across Teams Agencies want to enforce consistent communication standards (e.g., always email for client support). Better UX for Large Teams Reduces mistakes and additional steps, improving the user experience and reducing support tickets. Impact Without This Feature -- Increased risk of replying via SMS when Email was intended -- Inefficient workflows and time wasted switching channels manually -- Difficulty maintaining communication standards -- Higher SMS cost and possible A2P compliance exposure Summary Please allow users and account admins to set a default reply channel (such as Email) in Conversations, and optionally force or enforce that default unless explicitly overridden. This would immediately improve consistency, efficiency, and accuracy in messaging workflows.
