Fill your busy season before it starts. Edit a headline, offer, call-to-action and QR code, then mail it — with optional front-desk follow-up calls. Start on the free plan, no credit card required.
Start Free — No Credit CardDemand for most service businesses moves with the calendar — the first cold snap, the pre-summer rush, the holiday gifting window. A postcard that lands a few weeks before the season starts puts your offer in front of customers right when they're about to need you. Mail it ahead of the wave instead of competing in the middle of it, and pair it with a follow-up call to lock in the booking.
A time-bound seasonal deal — pre-season tune-up, holiday package, spring cleanup — creates a reason to act now. Schedule the mailing to drop just before demand peaks so you're first in the door.
Industry studies (ANA Response Rate Report) typically report direct-mail response in the low single digits, with house lists at the higher end of that range — well above typical email. Treat any figure as an estimate, not a promise.
A postcard plus a phone call from your front desk a few days later (the built-in Call Queue, a Pro feature) consistently outperforms either channel alone. PostKnock sequences both for you.
Response and ROI vary widely by industry, offer, timing, and list quality. Figures above are industry-standard ranges, not PostKnock results.
Each is a 4×6 front design with an editable headline, offer, call-to-action, and a real QR code (link it to your booking page or phone number). Open any one in the Design Studio and make it yours — for free.

Export customers or prospects from your existing system as a CSV and import the file — the wizard auto-maps name, address, and phone columns. PostKnock does not connect to your CRM directly; it's a CSV import. Or use EDDM-style saturation mailing to blanket nearby ZIP routes without a named list.
Postcards print and mail via USPS First-Class, with QR-scan tracking built in, so you can drop them ahead of the season. On Pro, layer in front-desk follow-up calls through the Call Queue and run a multi-touch wave sequence (up to 5 waves) from a pre-built playbook.

Seasonal resources & industry templates
Yes. Editing any template in the PostKnock Design Studio is free, with no credit card required. You only pay per piece when you actually mail — from $1.05 per 4×6 card on the Free plan and from $0.79 on Pro. Printing and USPS First-Class postage are included in that per-piece price.
Aim to land in mailboxes a few weeks before demand peaks — ahead of the heating or cooling season, before the holidays, or just before spring cleanup. First-Class mail typically delivers in a few business days, so build in lead time for printing and transit when you schedule the drop. The goal is to reach customers while they're deciding, not after they've already booked elsewhere.
A clear seasonal hook ("Beat the first cold snap"), a specific time-bound offer with a deadline, your business name and phone number, and an easy next step — a QR code to your booking page works well. A firm "book by" date gives customers a reason to act now instead of later. Every field in these templates is editable.
Results vary by industry, offer, timing, and list quality, so treat any number as an estimate. Industry studies (such as the ANA Response Rate Report) typically report direct-mail response in the low single digits, with house lists — like your own past customers — landing toward the higher end of that range. Pairing the postcard with a follow-up phone call generally lifts response further.
PostKnock includes pre-built playbooks and starting designs for 50+ industries — HVAC, med spa, lawn care and landscaping, dental, optometry, pest control, pool service, auto repair, and many more. The three above are examples; you can adapt any template to your business and season in the Design Studio.
Yes. If you want to reach an area rather than a named list, EDDM-style saturation mailing lets you blanket nearby USPS carrier routes without uploading individual addresses. If you do have a customer or prospect list, export it from your existing system as a CSV and import it — the wizard auto-maps the columns. PostKnock does not connect to your CRM directly; the supported path is CSV export and import.
Yes, on the Pro plan. After a postcard is delivered, the built-in Call Queue populates so your front desk can work a daily list of follow-up calls using per-wave scripts. You can also run multi-touch wave sequences (up to 5 waves) so non-responders automatically advance to the next touch during the season.
PostKnock supports three sizes: 4×6, 6×9, and 6×11. The templates above are shown at 4×6, the most common and lowest-cost option. Larger 6×9 and 6×11 cards give a seasonal offer more room to stand out in the mailbox — you can switch sizes in the Design Studio.
Customize a seasonal promo template free, then mail it — with optional follow-up calls.
