The Reminder Cadence VA Horizon Already Runs, and Where It Starts
VA Horizon runs a three-touch confirmation cadence on every booked solar appointment: a two-way text at 24 hours out asking the homeowner to confirm, a second touch at 2 hours out as the rep is getting ready to head over, and a final check-in at 15 minutes before the rep is committed to the drive. That sequence, and the research behind why each touch is timed where it is, is documented in full on a dedicated post about reducing solar appointment no-shows. This article is about the gap before that cadence begins, the stretch between when an appointment first gets set and when the 24-hour reminder fires.
Why the Gap Between Booking and the First Reminder Matters
A solar consult is not always booked the same day it gets set. Depending on rep and homeowner calendars, an appointment can sit for days, sometimes longer, before the 24-hour reminder is the first thing the homeowner hears from anyone again. A homeowner who goes quiet, forgets which company they spoke with, or starts to second-guess the appointment somewhere in that gap is a different problem than one who simply forgets after a same-week confirmation. The existing three-touch cadence is built to close the gap right before the appointment. It is not built to touch the gap that can open up right after the appointment is set.

Book a Solar CallWhat the General SMS Evidence Supports
The evidence for SMS as a reminder channel is well established. SMS reminders reduce no-show rates by 38 to 50% generally, with some programs reaching 60 to 70% reduction when combined with an easy-cancellation option. SMS carries a 98% open rate versus roughly 20% for email, and text messages are typically read within 3 minutes of delivery (Etisia). Timing matters as much as the channel: a 24-hour-before touch is rated the single most effective timing, a 2-hour-before touch is strong for catching last-minute cancellations, and a same-day-morning-only touch with no earlier reminder is comparatively weak. All of that evidence describes reminder effectiveness in the window immediately before an appointment, the exact window VA Horizon’s existing cadence already covers.
The Reasoned Case for a Warm-Up Text, and Its Limits
No source in this research specifically measures a pre-booking or early-funnel warm-up text’s effect on no-show rates as its own tactic. What can honestly be said is a reasoned extension: the same properties that make SMS an effective reminder channel, near-instant delivery, a 98% open rate, and a 3-minute typical read time, plausibly help an early message do a different job, not reminding a homeowner of a time they already agreed to, but confirming who called them, restating why they are getting a visit, and setting expectations for the reminders still to come. That is inference built on established SMS-channel evidence, not a directly measured result for this specific tactic, and it should be presented to a sales team that way.
Fitting a Warm-Up Text Around the Confirmation System, Not Into It
A warm-up text belongs right after an appointment is first set, or right after the initial qualifying contact if the exact time is not locked yet, not layered on top of the existing 24-hour, 2-hour, and 15-minute cadence. Sending a warm-up message the same day as the 24-hour reminder just adds a redundant touch and risks message fatigue instead of closing the actual gap. The two systems should never overlap: one covers the days or weeks between booking and the appointment, the other covers the hours immediately before it.
The Same Consent Rules Apply to an Earlier Text
A warm-up text is still an outbound message subject to the same consent requirements as any other text a solar sales org sends, timing does not create an exemption. A 2024 FCC rule lets consumers revoke calling or texting consent using any reasonable method, at any point, which means a homeowner who agreed to be contacted when the appointment was set has not necessarily agreed to be contacted indefinitely afterward (Nixon Peabody). Sending an early warm-up text does not require separate consent from the appointment-booking consent already given, but it is still bound by the same revocation rule as the reminder cadence that follows it, and a sales org should not treat an earlier touch as somehow lower-risk than a later one.
