New Features

  • Warm Transfer over Voice: Apten now supports warm-transfer mid-call hand-offs on the voice channel, briefing the human agent on the conversation before bridging the lead through.
  • Bulk Send-Message via CSV: Send a personalized first message to many leads at once by uploading a CSV. The bulk endpoint also supports variables.
  • Common Objections Analytics: A new optimization view clusters customer replies into common objections so you can see what leads push back on most often, and refine your prompts in response.
  • Backup Transfer Number: Configure a fallback transfer number that Apten will dial if the primary agent leg goes to voicemail or doesn’t pick up.
  • Profile-Level SMS Transfer: SMS transfer is now configured per customer profile (previously a single org-wide flag) so different brands or teams can route to different agents.
  • Update Lead API: New API endpoint for updating arbitrary lead properties without re-importing.
  • Email Forwarding for Attachments: Inbound emails with attachments can now be forwarded to a configured destination address (useful for routing into ticketing or CRM systems).
  • Configurable Short-Transfer Threshold: Define how short a transferred call has to be before Apten treats it as a non-connection and re-engages the lead.
  • One-Click Unsubscribe in Outbound Emails: Outbound emails now include the headers required for native one-click unsubscribe in the recipient’s inbox. This brings outbound email into compliance with bulk-sender requirements from major email providers and helps protect deliverability.
  • 2026 SMS Holiday Calendar: Holidays are automatically applied to outbound SMS scheduling so messages don’t go out on major US holidays.

Improvements

​
Voice Bot Enhancements

  • Faster Guardrail Decisions: Critical guardrail and reply-decision steps are now sub-second with automatic fallback for higher reliability.
  • Business Hours in Voice Agent: The voice agent is now aware of your configured business hours so it answers scheduling questions correctly mid-call.
  • Smarter Voicemail Detection: New voicemail detection on outbound AI calls for higher accuracy across carriers.
  • Phone Number Validation: Invalid phone numbers and unsupported regions are caught and surfaced as clear errors instead of silent failures.
  • Cold Transfer Greeting: Leads now hear a customizable greeting on the SMS-initiated cold-transfer path.

​
Conversations & Automations

  • Follow-Up Reply Tracking: Each follow-up step (SMS, email, call) now tracks whether it produced a reply, powering richer analytics.
  • Email Bounce Handling: Bounce-back emails no longer raise errors and are filtered out of the conversation thread.
  • Inbound Email 100-Message Limit: Long inbound email threads are now safely capped to prevent runaway processing.
  • Stay-on-Node Behavior: When a node has no children, the agent stays on that node instead of transitioning to an end-state, supporting open-ended branches.

​
UI/UX Improvements

  • Webhook Secrets in Settings: Webhook URLs and signing secrets are now displayed (with copy buttons) in the developer settings table.
  • Email Unsubscribe Field in Integrations: New CRM-integration setting to map an unsubscribe field, with redesigned integration settings layout.
  • Customer Profile List Pagination: The customer-profile list now paginates correctly for large workspaces.
  • Phone Number Type Badges: Improved visual badges and explanatory copy for phone-number types in settings.
