Home care marketing in El Cajon:
a direct mail plan for senior care
By Best Direct Mail, San Marcos · Numbers from USPS and the US Census Bureau
El Cajon is a valley ringed by hills, and its older residents live in both. Down in the valley, around downtown and Bostonia, older houses share the streets with apartments and mobile home parks, some of them senior communities. Up on the edges, in Fletcher Hills, Granite Hills and on Mount Helix, many residents have owned the same home since the 1960s, 70s or 80s and want to stay there.
Two groups decide on senior care: the older adult and a grown son or daughter who helps. In El Cajon many of those children live nearby, in Rancho San Diego or the next town over, so a good plan reaches both. Below we start with the public numbers for each ZIP Code, then go neighborhood by neighborhood: who lives there, what to offer and how to mail it. After that come home care versus assisted living, a year of mailings and what every senior care postcard in California should include.

El Cajon by ZIP Code
| ZIP Code | Residents 65 or older | Residents 75 or older | Seniors living alone | Median household income |
|---|---|---|---|---|
| 92020 Central and west El Cajon, downtown, Fletcher Hills and the El Cajon side of Mount Helix | 16% | 6% | about 1,400 | $76,032 |
| 92021 North and east El Cajon, Bostonia and Granite Hills | 15% | 6% | about 2,360 | $74,013 |
| 92019 South El Cajon, Rancho San Diego and part of Granite Hills | 19% | 7% | about 1,540 | $101,973 |
What the columns tell you:
- Residents 65 and 75 or older: where older adults make up the biggest share of the neighborhood, and so where EDDM® wastes the fewest cards. The need for daily help grows with age.
- Seniors living alone: households of one person 65 or older. They are the people most likely to need help at home, and the ones whose families worry most.
- Median household income: higher incomes point to private-pay, live-in and full-service care. Lower incomes point to clear hourly rates, short visits and the benefits you accept.
These figures cover whole ZIP Codes, and single routes inside them can be quite different. Our EDDM® route planner shows income, age and household size for every route before you choose.
Residents 65 and 75 or older, seniors living alone and income are US Census Bureau American Community Survey 5-year estimates for the ZIP Code area. Seniors living alone are one-person households of someone 65 or older.
What a mailing costs: $2,682 for 5,000 homes with our recommended 8.5 × 11 EDDM® postcard, including printing and postage. See our EDDM® prices for other quantities.
What to mail in each neighborhood
Fletcher Hills (92020)
On the west side next to La Mesa and Grossmont College, Fletcher Hills has single-family homes from the decades after the war on curving streets that climb into the hills. Many owners bought in the 1960s, 70s and 80s and are now retired, which makes this one of the clearest home care areas in the city.
- What to offer: help that keeps people in their own homes: a few hours a week of help with meals, errands and housework, rides to appointments, and more care after a hospital stay. A free in-home assessment is an easy first step.
- How to mail: EDDM®, every month or so. Most routes are owner-occupied houses, so whole routes reach older residents for the lowest postage.
Downtown, Bostonia and the valley (92020 and 92021)
Around Main Street and north toward Bostonia, single-family streets from the 1940s to the 70s mix with apartments, duplexes and several mobile home parks, some of them for residents 55 and older. Many households look closely at cost.
- What to offer: clear hourly rates, short visits, and whether you accept long-term care insurance or veterans benefits. A friendly weekly visit and help with shopping go a long way here.
- How to mail: EDDM® to the routes closest to your office, or a mailing list by age to reach older residents on streets with many apartments. Mobile home parks for older residents can be mailed park by park.
Mount Helix and Granite Hills (92020 and 92021)
The El Cajon side of Mount Helix has custom homes on large hillside lots and winding roads, and Granite Hills has single-family homes from the 1950s through the 80s on larger lots. Many owners have been here for decades, and big lots and steep driveways are harder to manage alone.
- What to offer: full-service home care, live-in or around-the-clock care, memory care at home and a care manager the family can call.
- How to mail: a mailing list filtered by age and length of residence, since the homes are spread out and much of the area is unincorporated with El Cajon addresses.
Rancho San Diego (92019)
South of the city, Rancho San Diego was built from the 1970s on around Cuyamaca College and the shopping centers along Jamacha Road. Many households are families with children at home, and many of the parents are the grown children who help an older parent in the valley or the hills nearby.
- What to offer: peace of mind for the family: updates after every visit, respite care so the family caregiver can take a break, and evening and weekend calls. For assisted living, a tour with lunch the whole family can join.
- Timing: before Thanksgiving, when families get together, and in January, when many of them start calling.
- How to mail: EDDM® on the family tracts closest to your office or community.

Home care or assisted living: who to mail in El Cajon
- Home care agencies can mail every home on the routes they serve with EDDM®, or use a mailing list to reach households by age and how long they have lived in the home. The table above shows where older residents and seniors living alone are most common.
- Assisted living and memory care communities do best mailing every home within a few miles, since families want a parent close by. Pick the routes around your community in our EDDM® route planner, including La Mesa, Santee and Lakeside if you are close, and keep the card about the community itself.
- Both should mail the same homes again and again. Families often take months to decide, and the card on the counter when they are ready is the one they call.
Mail also works well beyond homes. Doctors' offices, discharge planners at Sharp Grossmont Hospital in La Mesa and other nearby hospitals, and senior centers refer families every week, and a card or letter to them a few times a year keeps your name in mind. Ask us about a mailing to referral partners in El Cajon and the rest of East County.

A year of senior care mailings in El Cajon
| When | Who gets it | What the card says |
|---|---|---|
| Every 4 to 6 weeks | The same routes around your office or community | Who you are, what you help with and one low-pressure next step |
| January to February | Neighborhoods with many older residents and the family neighborhoods nearby | After the holiday visits: a free in-home care assessment or a tour |
| Spring | Neighborhoods with many people living alone | Help around the house, rides to appointments and a friendly visit each week |
| Summer | Family neighborhoods | Respite care while the family caregiver takes a vacation |
| September to October | The routes around your community | An open house, a lunch or a talk for family caregivers, mailed 2 to 3 weeks ahead |
| November | Family neighborhoods and the routes closest to you | Coming home for the holidays? What to look for when you visit, and how to reach you |
You don't need every mailing. Most El Cajon agencies and communities start by mailing the same nearby routes every month or so, then add the seasonal cards. Our senior care direct mail guide has more ideas for each one.
What every El Cajon senior care postcard should include
- Your license number. Home care organizations and assisted living communities (Residential Care Facilities for the Elderly, or RCFEs) in California are licensed by the Department of Social Services. Showing the number tells families you are legitimate.
- Who pays, said plainly. Medicare generally does not pay for ongoing non-medical help at home or for assisted living. Don't suggest that it does. Say whether you accept long-term care insurance or veterans benefits, if you do.
- Offers spelled out: what a free assessment or a move-in special includes and when it ends.
- For assisted living, describe the community, not the residents you want. Rooms, care, meals, activities and your location. Communities are housing, and fair housing rules apply to their advertising.
- Large type and a phone number a person answers. Many readers are older, and many callers want to talk to someone right away.
- Where you are in El Cajon, with a landmark people know and the areas you serve.
These are general points, not legal advice. Your licensing office or an attorney can confirm the exact wording, and we adjust any design to match.

Frequently asked questions
Where do most older residents live in El Cajon?
Many live in Fletcher Hills, Granite Hills and on Mount Helix, where owners have often been in their homes for decades, and in the valley around downtown and Bostonia, which has several mobile home parks, some of them for residents 55 and older. The table above shows the share of residents 65 and 75 or older and the number of seniors living alone in each ZIP Code.
Should a home care agency use EDDM® or a mailing list in El Cajon?
EDDM® is the cheapest way to cover owner-occupied routes like Fletcher Hills. A mailing list filtered by age and length of residence works better on Mount Helix and in Granite Hills, where homes are spread out, and on valley streets with many apartments.
Should I mail the mobile home parks in El Cajon?
Yes, if you serve the area. Some parks are senior communities, and a simple, friendly card about help at home, rides and a weekly visit can reach every resident. Mail the parks closest to your office first.
How often should senior care postcards be mailed?
Every four to six weeks to the same homes. Families often take months to choose care, so being there again and again matters more than reaching a big area once.
Do you mail in El Cajon?
Yes. Our print shop is in San Marcos, and we mail EDDM® across San Diego County, including El Cajon and the rest of East County, taking your postcards to the Post Offices that deliver your routes.
