Key takeaways
- Hangers suit streets near your jobs; mail reaches a targeted list across wider areas.
- Never put hangers in mailboxes, and always skip homes with no soliciting signs.
- Give each piece its own tracking number or code so results are measurable.
A door hanger and a postcard can carry the same offer and still do completely different jobs. One arrives by hand, usually on a street where your crew has just been working. The other arrives with the day's mail, sent to a list you chose on purpose. Treat them as interchangeable and you end up with hangers scattered across streets where nobody has heard of you, and postcards going to renters who cannot change the locks.
This guide walks through when each format makes sense for a security dealer, locksmith or smart home installer, how to design both, where the legal and courtesy lines sit, and how to tell whether any of it is working.
Two formats, two jobs
Door hangers work at close range. They make the most sense on the streets around a job you just finished, where neighbors saw your van in the driveway and may already be curious. A hanger that says, in effect, "we just helped a neighbor on this street" is local by definition. The cost is mostly labor and time, and the reach is limited to how many doors your team can walk.
Direct mail works at a distance. It lets you reach a specific set of homes spread across your whole service area, such as recent buyers, owner-occupied homes or houses built before a certain year. The cost is mostly printing and postage, and the targeting is only as good as the list behind it.
Many dealers end up using both: hangers to build familiarity around active jobs, and mail to reach the particular homeowners who are most likely to need what they sell. The mistake is expecting one format to do the other one's job.
Designing a door hanger that gets read
A hanger gets a few seconds of attention as someone pulls it off the knob on the way inside. Design for that moment.
The front
Keep it to a short headline, one sentence of explanation and a phone number big enough to read from the porch. A friendly photo of your actual crew or truck, used with permission, does more than a stock image of a masked figure. Skip scare imagery entirely. It makes a local business look like a gimmick.
The back
The back is where you can add a little detail: the services you offer, your service area, your license number where your state requires it, and an honest reason to call soon. A seasonal lock check, a free inspection for new owners, or a note that the crew is working nearby this week are all fair reasons. Countdown deadlines and invented scarcity are not.
Print on stock heavy enough to survive a damp morning, and make sure the die-cut hole actually fits common door handles. It sounds minor until a whole box of hangers slides off the knobs in the first breeze.

Choosing a direct mail format
Postcards are quick to read and need no opening. They suit simple messages, like a welcome to new homeowners or a reminder about rekeying. Letters in envelopes give you room to explain, which helps when the offer needs context, such as inspecting and resetting equipment a previous owner left behind. Folded self-mailers sit somewhere in between.
Whatever you choose, the piece should look like it comes from a local business, because it does. Never design mail to resemble a bill, a past-due notice, a government form or a message from the homeowner's lender or insurer. Beyond being dishonest, mail that imitates official or financial documents can run into federal and state rules.
If a mail piece is the first step before a phone call from your team, the call still has to follow the rules. Check numbers against the National Do Not Call Registry and your internal do-not-call list, and remember that automated calls and marketing texts generally require the person's prior express written consent.
Where hangers can and cannot go
Door-to-door distribution comes with rules, and they differ from place to place. A few apply almost everywhere in the US, and the rest you have to look up locally.
- Mailboxes are off limits. Federal law reserves the mailbox for postage-paid mail, so nothing goes in it, on it or tucked under its flag.
- Respect "no soliciting" and "no flyers" signs. Walk past those houses and note them so the next route skips them too.
- Check city and county rules. Some places require a solicitor or distributor permit, limit hours, or regulate how printed material may be left at homes.
- Ask before entering private communities. Gated neighborhoods and many HOAs have their own policies.
- Leave the hanger on the front door handle. Do not open storm doors, reach into enclosed porches or cut across lawns and garden beds.
- Carry identification. Crews should have company ID and a copy of any required permit.
Hangers that blow into the street become litter with your name on it. Pick up any strays on the walk back to the truck.
Tracking what comes back
If you cannot tell which piece produced a call, you cannot decide what to print next. Give each campaign its own way to respond: a separate phone number, a short web address or a code the caller mentions. Train whoever answers the phone to ask how the caller heard about you and to write it down every single time.
Say, purely as a hypothetical, you run hangers around three finished jobs in one month and send a postcard to recent buyers across your service area in the same month. If both pieces share one phone number, the calls blur together. With separate numbers, you can see which one led to booked appointments and, just as useful, which one led to installs rather than quick price questions. Over a few campaigns, that record tells you where your time and print budget belong.
Questions to ask your printer or mail house
Before placing an order, it is worth asking:
- What paper weight and coating do you recommend for hangers that sit outside?
- Can you test the die cut on an actual door handle before the full run?
- How do you handle address hygiene, such as removing undeliverable or duplicate addresses?
- Can you remove a list of addresses that have asked not to receive mail from us?
- What postage options do you offer, and how long does delivery usually take for each?
- Can you print a different tracking number or code on separate batches?
- Who owns the mailing list after the job, and do you keep or reuse our data?
Keeping the list honest
Hangers depend on good routes and mail depends on a good list. SecureYrHome provides homeowner and property data tools that security businesses use to build mailing lists by area and property details and to plan canvassing routes, which makes both formats easier to aim. The offer, the design and the courtesy at the door are still what lead a homeowner to call.
