Missed-call text-back · custom build

Missed-call text-back, built around your stack

When a call goes unanswered, a text-back keeps the lead warm. We build this custom around the phone, CRM, and calendar tools your team already uses.

Why this matters

The cost of a missed call for a local business

  • Most missed callers never call back

    After-hours, lunch rush, double-booked staff — the call goes to voicemail and the lead moves on to the next result. The buyer was ready to book a minute ago; tomorrow they aren't.

  • Voicemail is the wrong channel for the way people talk now

    Texting is how people communicate with businesses. A short, branded text-back within seconds of the missed call meets the buyer where they already are.

  • Generic SaaS auto-responders don't fit your real workflow

    Off-the-shelf tools assume your phone, CRM, and calendar match their template. We build around the stack you already pay for so the text-back actually books the appointment.

What we build

A workflow wired into the systems you already use

We design a missed-call text-back flow around your existing phone provider, CRM, and calendar — not a packaged SaaS. The trigger fires on a missed call, the text goes out with your brand voice, the response lands in the inbox your team already watches, and the booking flows into the calendar your team already runs. We recommend a stack during scoping if you don't have one yet.

Proof

Concept
  • Illustrative flow

    Concept walkthrough of how a missed-call text-back can chain into intake, booking, and follow-up steps. Real implementation is scoped per engagement around your phone provider, CRM, and calendar.

  • Recommended-stack pattern

    When a buyer doesn't yet have a phone, CRM, or calendar combination, we recommend a stack during scoping based on the volume of calls, the team's daily tools, and the integrations the rest of the business needs.

Frequently asked

  • Does this lock me into a specific phone or SMS provider?

    No. We don't pre-pick Twilio, Telnyx, or any other vendor. We build around the provider your team already uses where practical, or recommend one during scoping if you don't have one yet.

  • How long does it take to set this up?

    Most engagements run in weeks rather than months. The exact timeline depends on which phone, CRM, and calendar tools we're wiring into and how the booking step is handled. We give you a written scope and budget range up front.

  • How is this different from off-the-shelf auto-responder tools?

    Generic auto-responders send a text and stop there. We design the full workflow — the trigger, the message, the response routing, the booking, and the follow-up — so the missed call actually turns into a booked appointment in the calendar your team already runs.

  • Who does the work?

    3sixs is founder-led, AI-native, and human-reviewed. The same team you talk to during scoping designs and ships the workflow. We're a Fort Worth studio serving the DFW area.

  • What happens after it ships?

    We stay engaged through the first weeks of real call volume to tune the message, the timing, and the routing. Long-term support is a separate written agreement when it makes sense.

  • What should I ask for on the contact form?

    Tell us the phone provider you use, where missed-call follow-up currently breaks down, and where the booking should land. Don't worry about specifying the integration — we'll work it out during scoping.
