Quick answer: plan on mailing the same routes at least three times before you judge the campaign, typically 4 to 8 weeks apart for most local businesses (tighter for restaurants, looser for big-ticket home services). The single most expensive EDDM mistake isn't a bad design or a wrong route; it's spending the whole budget on one giant drop, getting a quiet first week, and quitting. Repetition is how mail works.

Why One-and-Done Mailings Underperform
Twenty years of running these campaigns has made us repeat the same advice to every new client:
- Familiarity does the selling. The first piece introduces you; the second feels familiar; by the third, you're "that pizza place that keeps showing up" when the household actually needs you. One exposure rarely catches a household on the day they're ready to buy.
- Mail has a long tail. Menus get pinned to fridges and service cards live in junk drawers until the AC dies in August. Judging a drop by week one undercounts it badly; give each wave time to land before reading the results.
- Timing is a lottery you can re-enter. Any single Tuesday, most households don't need a roofer. Mail quarterly and you're in the mailbox the week the hailstorm hits.
This is also why we'd rather see you mail fewer routes more often than more routes once. Seven great routes hit three times beats twenty routes hit once, almost every time, on the same budget. (Picking those seven is the carrier-route chapter.)
Cadence by Business Type
| Business | Suggested cadence | Why |
|---|---|---|
| Restaurants, pizza, coffee | Every 3 to 4 weeks | Short purchase cycle; menus expire from fridges |
| Home services (HVAC, roofing, lawn) | Every 6 to 8 weeks, heavier before peak season | Long consideration; be present when the need hits |
| Dental, medical, vets | Every 6 to 8 weeks | New-patient decisions are slow; steady presence wins |
| Retail, gyms, salons | Monthly, synced to promotions | Each wave carries a fresh offer or season |
| Real estate farming | Monthly | Name recognition is the entire game |
| Grand openings | 3 waves: 2 weeks before, opening week, 3 weeks after | Build anticipation, capture the moment, convert stragglers |
These are working defaults, not laws; the right cadence is the one your budget sustains for a full cycle. Three modest waves beat one impressive drop.
Making the Budget Stretch Across Waves
- Divide the budget by three first. Whatever the total, a third per wave on your best routes is the plan; expanding routes comes after the cadence proves out.
- Keep the design, rotate the offer. Consistent branding compounds recognition; a fresh deadline per wave gives each piece a reason to act now. Design is one place not to cut; a weak offer on a cheap-looking card wastes the postage behind it.
- Reuse the route map. The USPS tool saves orders and has a repeat-order button that reloads your exact routes, and we keep every client's route map on file; wave two is a phone call, not a project.
- Postage stays flat. Each Retail piece costs the same $0.247 whether it's your first wave or your fifth, and printing in combined runs lowers the per-piece print cost across waves. Postage at Catdi Printing is always a pass-through, what USPS charges and nothing more.

How to Tell the Waves Are Working
- Give every wave a trackable handle: a unique coupon code, a QR code, or a "mention this card" line, so responses attribute to mail and not luck.
- Watch the trend, not the wave. Response typically builds across a sequence as recognition compounds; flat-to-rising across three waves on good routes means keep going.
- Re-read your routes once a year. Neighborhoods change; an annual pass through the route demographics keeps the map honest.
Frequency FAQ
Is it too much to mail the same houses every month?
For short-cycle businesses like restaurants, no; a monthly menu or offer reads as useful, not spammy. For long-cycle services, every 6 to 8 weeks keeps presence without fatigue. The piece earns the cadence: useful offers welcome repetition.
Can I automate repeat EDDM drops?
USPS lets you save and repeat orders in the EDDM tool (drop dates schedule up to 30 days out), and we run standing wave schedules for clients: same routes, fresh artwork, on calendar autopilot.
Should every wave use the same postcard?
Same look, different hook. Keep colors, logo, and layout consistent so recognition builds, and change the headline offer and deadline so each wave creates new urgency.
How long before I see results from a wave?
Responses usually start within days of delivery and trickle for weeks; service businesses see the longest tails. Judge each wave after it's had a few weeks to breathe, and judge the campaign after the full sequence.
What if the first wave gets zero response?
First, check the mechanics: did the offer give anyone a reason to act, and were the routes a real fit (the fit test)? Fix the offer before abandoning the routes; geography rarely fails twice, weak offers usually do.
Put Your Neighborhood on a Schedule
The businesses that win with EDDM treat it like rent for mailbox real estate: paid on schedule, on the same routes, until the neighborhood knows them by name. We'll build the sequence, hold your route map, and handle every wave end to end. Request an EDDM quote, see our EDDM service, or call (713) 882-4629.
