Service interval reminders, $X off coupons, and quick-lube recall. Built for oil change shops.
Quick-lube wins on convenience and recall. The shop that lands a postcard the week your customer hits 5,000 miles past their last visit gets the bay. The one that doesn't? Loses to the chain on the corner.
Service Reminder — 2 waves, mileage-based timing, follow-up call after Wave 1
"Time for your next oil change." Specific oil type from last visit (5W-30 synthetic, 5W-20 blend). $5–10 off coupon. QR to online booking or call-ahead.
Outbound call 10 days after delivery. "Wanted to make sure you got the reminder — want to come in this week? In-and-out in 10 minutes." Pre-loaded script.
Second postcard for non-responders. Stronger offer (free top-off through next visit) and an upsell hook (free brake light check, free tire pressure check).
Four design styles, all themed for your oil change shop and ready to customize. Same offer, same call follow-up — just pick the look that fits your brand.

Choose "Service Reminder." Wave timing, call scripts, and postcard copy are pre-configured for oil change recall. You only customize the offer ($5 off, $10 off, free top-off) and your shop branding.
Export past customers from your point-of-sale (Mitchell 1, ROwriter, Lubeshop) as CSV. Filter by last visit 90+ days ago for conventional or 150+ days for synthetic. Our import wizard auto-maps name, address, phone, last visit date, and oil type.
Postcards mail automatically via USPS within 1–2 business days. Your call queue populates 7–10 days after delivery. Wave 2 schedules itself 35 days later for non-responders.
Scripts are pre-loaded. Staff logs call outcomes (booked, voicemail, declined). Booked customers drop out and re-enter on their next interval.
A typical oil change shop has 1,500 past customers in the last 12 months. Here's what a 2-wave service reminder campaign looks like:
2.5–4:1 ROI per cycle — and the same customers cycle back every 3–6 months, compounding the return.

Specific oil change shop campaigns
Most quick-lube point-of-sale systems (Mitchell 1, ROwriter, Lubeshop) record last visit date and odometer reading. Estimate annual mileage at 12,000 miles for typical drivers (1,000 miles/month). For full-synthetic customers, plan the reminder around 5,000 miles or 6 months — whichever comes first. For conventional oil customers, target 3,000 miles or 3 months. PostKnock supports custom CSV columns so you can include the recommended interval and recommended next service on each card.
First name, last name, mailing address, phone, last visit date, last odometer reading, and oil type (conventional, synthetic-blend, full-synthetic). Most quick-lube management systems export all of this in a single CSV. Phone is optional but enables the Wave 1 follow-up call that closes 30–50% of the booked visits.
PostKnock oil change postcards start at $1.05 per 4x6 postcard on the Free plan and drop to $0.79 on Pro. No setup fees, no minimums, no contracts. Pricing includes printing and USPS First-Class postage.
$5 off conventional and $10 off full-synthetic outperforms percentage discounts. Tie the discount to a specific service ("$10 off your full-synthetic oil change + free top-off through next visit") rather than a generic coupon. Customers respond to specifics. Avoid <$5 discounts on conventional oil — the response rate doesn't change much from $0 off because $5 off a $40 service feels like nothing.
Only if you have it in your data. If your POS exports the oil type from the last visit, include it on the card: "Time for your next 5W-30 full synthetic." The specificity converts much better than "time for an oil change." If you don't have oil-weight data, skip it — don't guess.
10 minutes is the gold standard ("in by 10, out by 20"). It matters for marketing because your direct mail can lean into convenience: "In and out in 10 minutes — no appointment needed." Quick-lube wins on convenience and recall. The competitor that mails the reminder before yours and promises a 10-minute visit gets the customer.
Stop guessing when customers will come back. Start mailing the reminder that gets them in this week.
