What Should Electricians Put on a Direct Mail Postcard?

An electrician postcard should tell the recipient three things quickly: what electrical service is being promoted, why it may matter to them, and what they should do next.

The message changes with the job. A panel-upgrade postcard should not read like a standby-generator card. EV charger installation creates a different homeowner trigger, different technical questions and usually a different online destination.

The postcard also needs to represent the electrical work accurately without claiming to know something about the recipient’s property that the contractor has not inspected. Oklahoma adds another consideration: the Electrical Contractor State License Number must be displayed on advertising.

Name the Situation, Not a Diagnosis

Panel and service-upgrade campaigns are strongest when they begin with something the homeowner already knows is happening, such as:

• Planning an EV charger installation
• Adding a hot tub, workshop or other equipment
• Remodeling or adding living space
• Having an insurer or home inspector flag an electrical concern

Those situations can create a reason to have the electrical system evaluated, but they do not prove that a particular panel is unsafe, undersized or defective.

A headline such as Planning to Add an EV Charger? can naturally introduce an electrical evaluation. Your Electrical Panel Is Unsafe makes a specific condition claim about a property the advertiser may know nothing about.

The postcard should give the homeowner a reason to contact the contractor. The electrician makes the electrical determination.

Generator Postcards Need Careful Claims

Standby-generator advertising requires similar discipline. Terms such as whole-home backup, equipment runtime, automatic operation and specific coverage claims can imply technical performance.

Those statements should match the equipment being offered and the way the contractor designs and installs the system.

Useful generator postcard content can focus on:

• Standby-generator installation
• Backup-power planning
• Consultation or estimating
• Installation territory
• A clear way to schedule an evaluation

Technical performance language should come from the contractor or approved manufacturer information rather than being added simply to make the mailpiece sound stronger.

EV Charger Postcards Should Anticipate the Electrical Question

Someone considering an EV charger already understands the product they want. The electrical question is whether the home’s existing system is appropriate for the installation and whether additional work may be needed.

That can be handled without implying that every charger requires an upgrade.

Headline:
Adding a Home EV Charger?

Supporting line:
Have your electrical system evaluated as part of planning the installation.

Any tax credit or rebate mentioned on the postcard also needs the current-source check described below before the piece is printed.

Rewiring and Older-Home Campaigns Need the Same Restraint

Older housing can help define an audience without proving that an individual property needs rewiring.

A campaign can introduce rewiring, renovation-related electrical work or electrical evaluations with language such as:

Updating an Older Home? Ask About Electrical Upgrades During the Project.

That identifies a recognizable homeowner situation without claiming that the recipient’s wiring is defective or requires replacement.

Oklahoma Requires the Electrical Contractor State License Number on Advertising

Oklahoma Administrative Code 158:40-5-4(b) states that the Electrical Contractor State License Number must be displayed on all advertising, contracts and bids.

The section excludes uniforms and promotional items such as pens, pencils, key chains and tape measures from its advertising requirement. A direct-mail postcard is not listed among those exclusions.

The rule does not prescribe a special type size or format for the license number on ordinary advertising.

Separate requirements in subsection (a) apply to contractor vehicles. Vehicle displays must use the “OK” prefix and meet minimum lettering requirements. Those vehicle provisions should not simply be transferred to postcard artwork.

For direct mail, keep the contractor license number legible and near the company-identification information instead of burying it in tiny copy.

Before printing, confirm that the number displayed is current and is the correct Electrical Contractor State License Number associated with the firm.

What Should Go on the Front of an Electrician Postcard?

The front should identify the electrical job quickly.

1. The homeowner trigger or service

Examples include:

Planning to Add an EV Charger?

Considering Standby Power?

Remodeling and Need Electrical Upgrades?

Need a Panel or Service Evaluation?

2. A relevant image

The image should show the kind of work being promoted. Generator campaigns should show generator work. EV charger campaigns should show a believable residential charger installation. Panel campaigns should use relevant electrical-project imagery.

Actual contractor project photographs can provide stronger proof when they are clear, current and approved for advertising use.

3. Company identification

The contractor’s name should be easy to find without overwhelming the service message. The recipient should understand what the card is about and who sent it before turning it over.

What Should Go on the Back?

The back should answer the questions created by the front.

Include:

• A concise explanation of the service
• Geographic service area
• Appropriate proof
• Electrical Contractor State License Number
• One dominant response method
• Phone number and website as appropriate
• QR code or short URL when it leads to useful supporting content

Useful proof can include current review information used accurately, years in business, appropriate credentials, authorized manufacturer status, actual project photography or a genuine service warranty.

Match the Postcard Content to the Electrical Job

If the headline, photograph, proof and QR destination appear to belong to different campaigns, the postcard probably lacks a clear objective.

EDDM Changes What Fits on an Electrician Postcard

USPS Every Door Direct Mail works at the carrier-route level. Its online tool provides route-level information including residential delivery counts and Census-derived averages for factors such as age, household size and household income.

Those numbers describe a route. They do not identify individual homes that need electrical work.

EDDM can be configured for residential-only delivery or for residential and business addresses on selected routes. Residential-only delivery still does not distinguish homeowners from renters.

That matters for services such as panel upgrades and standby generators, where the person receiving the card may not have authority to approve work on the property.

If an EDDM campaign is specifically aimed at owners, the creative can make that audience clear: Homeowners Planning an Electrical Upgrade…

The mailpiece also needs room for the appropriate postal indicia and addressing treatment, so postal requirements should be considered before the back of the postcard is filled with content.

For route selection, list strategy and postal logistics, visit Mercury Press Plus’s Direct Mail Marketing Services page. USPS also provides its Every Door Direct Mail route-selection tool.

Send the QR Code Somewhere Specific

The QR destination should continue the subject introduced on the postcard:

Panel postcard → panel/service-upgrade page

Generator postcard → generator page

EV charger postcard → EV charger page

Professional-referral piece → appropriate professional contact page

Sending every campaign to a homepage makes the recipient search again for the service that brought them there.

Scan the QR code from the final proof before printing and verify the destination on a phone.

Make One Response Method Dominant

A postcard can contain a phone number, website and QR code, but one should normally have visual priority.

If calls receive the fastest response, emphasize the phone number. If the company reliably handles service-specific online inquiries, emphasize the relevant QR code or URL.

Campaign-specific landing URLs, QR destinations, promotional identifiers or appropriately configured tracking numbers can also help distinguish direct-mail responses from other leads.

Should an Electrician Put Prices on a Postcard?

Be cautious when the final project scope cannot be determined without evaluating the property.

Panel replacement, generator installation, rewiring and many EV charger projects can vary substantially based on the existing electrical system and job conditions. A fixed price can create an expectation the contractor cannot honor.

Pricing is more defensible when the contractor offers a genuinely fixed-scope product or clearly defined promotion and can accurately state the applicable terms.

Otherwise, the call to action can focus on requesting an evaluation or estimate.

Manufacturer Logos and Incentives Need a Final Check

Before a postcard carrying manufacturer or incentive information goes to press:

• Confirm permission to use logos and trademarks
• Verify current dealer or certification status
• Follow applicable co-op advertising rules
• Check rebates, credits or utility programs against a current authoritative source
• Include required terms or expiration dates
• Have the contractor approve the final representations

Printed information cannot be corrected once those pieces are circulating, so temporary programs and outside claims deserve a final verification at proof.

What Should a Postcard to Realtors or Home Inspectors Say?

Professional-referral mail should be written for the referral relationship rather than copied from a homeowner campaign.

A realtor, home inspector or property manager may need to know:

• What electrical work the contractor handles
• Geographic service area
• Who to contact
• How evaluations or estimates are scheduled
• Whether the contractor can provide relevant documentation after completed work
• Any response-time representation the contractor can substantiate

A CTA such as Save this number for electrical repair referrals speaks directly to that audience.

Pre-Print Check for an Electrician Postcard

Electrical and content checks

Confirm:

• The postcard promotes the intended electrical service
• The homeowner situation is accurate and is not presented as a diagnosis
• Technical claims have contractor approval
• Generator, EV, panel and safety claims are supportable
• Manufacturer logos or credentials are authorized
• Any rebate or incentive is still current
• The correct Electrical Contractor State License Number is displayed
• Service territory, offers and pricing statements are accurate

Production and response checks

Confirm:

• Business name, phone and website
• Primary call to action
• QR destination
• Landing-page or phone response process
• Postal indicia and addressing space
• Mailing format
• Campaign tracking method, when used

These checks are considerably cheaper before production than after the mailpieces have been printed.

Questions Electricians Ask Before Printing

What size postcard should an electrician use?

There is no universal electrician postcard size.

The format should follow the mailing method, amount of content, photography and desired visual hierarchy. For EDDM, the piece must meet applicable USPS flat-size requirements, so the mailing method should be established before the artwork is finalized.

Mercury Press Plus can confirm the production formats available for a particular campaign before design begins.

Does the license number still matter when mailing existing customers?

OAC 158:40-5-4(b) applies to all advertising, contracts and bids and does not create a separate advertising exception for mail sent to existing customers.

If the mailpiece advertises the electrical contractor’s services, include the correct Electrical Contractor State License Number.

When should incentives and QR destinations be checked?

Check them again during final proof, immediately before production.

A rebate, tax credit, manufacturer program or landing-page URL can change between the initial design and the mail date. The final proof is the appropriate point to confirm that outside claims remain current and that every QR destination still works.
