The demo went well, the prospect said “send everything over” — and then went quiet. Two weeks later you’re wondering whether a fourth message makes you persistent or annoying. Here’s what the measured data says about the field you’re competing against:
Messages go out when your calendar clears, not when the buyer is at their desk. Random timing reads as random effort.
“Just checking in” asks the buyer to re-read the thread, remember why they cared, and reply. Nothing new in the message means nothing new to answer.
Most reps stop right before the window where deals re-engage — when budget clears, the competitor’s contract lapses, or the internal fire burns out.
Read those numbers as a competitive map. In Harvard Business Review’s 2011 audit — old enough that everyone has had fifteen years to fix it, and most still haven’t — a quarter of companies never followed up on a hot inbound lead, most of the rest were slow, and the ones that reached out within an hour were about seven times likelier to get the decision-maker. The bar you have to clear to stand out is astonishingly low — which is exactly why a systematic sequence moves your rate so much.
The at-bats compound, and the math is worth seeing in full. If each touch has reply chance p, the share of leads that ever answer after n touches is 1 − (1 − p)n. Plug in any honest per-touch rate and compare a two-touch habit with the eight-touch clock:
| Reply chance per touch | 2 touches | 8 touches | Multiplier |
|---|---|---|---|
| 5% | 10% | 34% | 3.4× |
| 10% | 19% | 57% | 3.0× |
| 15% | 28% | 73% | 2.6× |
The model assumes a steady rate, and in practice per-touch replies decay as a sequence runs — later touches convert below earlier ones. That’s why the table uses modest rates, why “double” is the conservative end of the curve, and why your own by-touch numbers (below) are the ones to trust. Either way the cost side is lopsided: at $0.01–0.05 per SMS and fractions of a cent per email, touches three through eight cost pennies against a four-figure deal.
Then hold this post to its own standard: pull your last 100 leads and count touches per reply. If your average is two or three touches, the back half of the clock is where your doubling lives — and your own CRM will show it within a quarter.
Stop deciding when to follow up. Decide once, then let the schedule run:
| Touch | When | Channel | The job |
|---|---|---|---|
| 1 | Within 24 hours | Recap + one clear next step | |
| 2 | 3 days later | Proof — how someone like them fixed this | |
| 3 | 7 days later | Call, voicemail if missed | Real voice, real rapport |
| 4 | 10 days later | Email or SMS | A useful resource, no pitch |
| 5–7 | Every 10–14 days | Rotate | Stay present through their buying cycle |
| 8 | Final | Email or SMS | The permission close — an easy yes or no |
Speed matters most at the very start. The same HBR research found firms that attempted contact within an hour were about seven times likelier to have a meaningful conversation with the decision-maker than those that waited even sixty minutes. Treat the 24-hour ceiling on touch one as a fallback — for an inbound lead, the right delay is minutes, which is exactly the case for automating it.
Day and hour matter too. The original lead-response research behind that audit (Oldroyd’s Lead Response Management study) found Wednesdays and Thursdays clearly beat Mondays for making contact, and late afternoon beat mornings for reaching leads by phone. Whatever window you choose, set it in the prospect’s time zone and let the system hold it for every lead.
The permission close reads like giving up, but it converts a vague obligation into a one-word answer. Buyers who ghosted for a month will reply “not now — check back in Q2,” and that’s an answer you can schedule against.
When the touch-3 call goes to voicemail, leave one — short, no ask to call back, next step named:
“Dana, it’s Alex at Ridgeline Solar — I sent the HOA rundown Tuesday. No need to call back; I’ll try you Thursday afternoon. If texting’s easier, that works too.”
Touches 5–7 rotate three shapes so the middle stretch never repeats itself: something that changed in their world (“your utility filed new rates for next year — here’s what it does to the payback math”), one more resource aimed at their named objection, and one light check pinned to a date they gave you (“you mentioned re-budgeting in October — worth a quick look before then?”). New information each time; never “checking in.”
Plan for 8–12 touches over 3–4 months. That feels long until you list why a genuinely interested buyer goes quiet:
None of those mean no. They mean not this week — and the rep still present when the blocker clears gets the reply.
Each channel does one thing well. Email carries detail and gives them something to forward, a call builds rapport no text can, and SMS gets read almost universally — published industry studies (Mobilesquared, Campaign Monitor) put text open rates near 98% against email’s roughly 20% — once you’ve asked “mind if I text you updates?” and gotten a yes.
Two rules keep the mix working: ask permission before the first text, and keep every send compliant — consent, quiet hours, and instant opt-outs are covered in the TCPA compliance guide. For picking the channel per message, see the SMS vs email comparison; field teams can adapt the solar-rep cadence day spacing.
A voicemail after a missed call is a legitimate touch — your voice, without interrupting their day. If you use ringless voicemail drops to do it at scale, the consent rules are stricter than most reps assume and vary sharply by state; check where ringless voicemail is legal before adding it to the sequence.
The whole system exists to produce a reply — so the moment one arrives, automation gets out of the way. Answer fast while the interest is warm, and never let a scheduled touch fire into an active conversation. A “not now” goes back on the clock for the quarter they named; a question gets a human answer within the hour if you can manage it.
Everything else — the clock, the send window, the merge fields, the quiet-hours guardrails — automate without guilt, and keep the judgment human: which proof fits this buyer, when to call instead of type, and when a thread has earned a phone call.
FollowUp runs this system for you — the cadence, the send windows, the personalization, and the compliance guardrails — and its AI reads every reply so only the ones needing a human reach you. The leads are already in your pipeline; the system is what converts them.
