Mail Gets Noticed, Email Gets the Click: How Dealers Lift Response 27%

Email is one of the most cost-efficient ways a dealership can put an offer in front of a shopper, and the sales data proves it generates results. Across 1.6 million Mudd Advertising dealer emails sent from August 2024 to October 2026, 3,626 vehicle sales were matched back to the emails buyers received.

Still, too many dealers treat email as an afterthought: a monthly newsletter, or a last-minute blast with no plan behind it. That leaves sales and service revenue on the table.

After 45 years working only with car dealerships, we've seen what separates email that gets ignored from email that fills the showroom. This article covers why email belongs in every dealership campaign: for your existing customers, for conquest shoppers, for the service drive, and above all, as part of a coordinated campaign with direct mail and your digital channels.

Email Sells Cars, Not Just Opens

Dealer email produces 2.2 cars sold per 1,000 emails, close to the 2.4 - 2.8 per 1,000 that direct mail typically delivers. That puts a low-cost digital channel within reach of the response rate of the industry's most trusted one.

Open and click rates matter, but they aren't the goal. The goal is a sold vehicle or a repair order. That's why Mudd measures email with matchback reporting, connecting the households that received an email to the vehicles they actually bought.

Three out of four campaigns selling at least one car is the number that should get a dealer's attention. Email isn't a branding exercise. Planned and targeted well, it's a sales channel.

Marketing to Your Existing Customers

Your own customer database is the warmest audience you have, and email is the fastest, least expensive way to reach it. In a recent week of Mudd database email across 15 dealers, 20% of customers opened and 17% of those openers clicked, well above the roughly 11% click-to-open rate typical for automotive email. Deliverability reached 99.4%.

These customers already know your store, your staff and your service drive. A well-timed email keeps that relationship active between purchases and puts your dealership first in line when they're ready to buy again. Database email works especially well for:

• Lease pull-ahead and equity offers. Reach owners who can upgrade now, often with little or no change to their monthly payment.

• Vehicle acquisition. Invite customers to get an appraisal and trade up, which also restocks your used inventory.

• Loyalty and owner communications. Model-year updates, owner events and appreciation offers that build retention.

• Service reminders. Covered in detail below, and often the highest-frequency reason to email your customers.

The outcome is retention. Every customer who buys their next vehicle from you, instead of the store down the road, is a sale you didn't have to win from scratch.

Database email results: October 26 to 30, 2026, 15 dealers, 44,700 emails sent.

Conquest Email: Reaching Shoppers Who Aren't Yours Yet

Conquest email puts your offer in front of in-market shoppers who have never bought from you, and it outperforms the benchmarks competitors advertise. Across 12.9 million Mudd conquest emails in 249 campaigns from 2025 through 2026 year to date, 16.8% were opened and 1.8% were clicked. Competing providers commonly advertise 12% to 15% open rates and a 1.5% click minimum.

The difference starts with the audience. Mudd builds conquest lists with the same audience tools used for our direct mail and digital campaigns, so email reaches households that are actually shopping, not just anyone with an inbox. Then each email is built around one clear action.

Two recent conquest campaigns show what that looks like:

The Chevrolet email featured specific trucks by stock number with savings, so 920 shoppers clicked straight through to discounted inventory. The Kia email asked owners about their current vehicle, and 653 clicked to see what it was worth. Each is a qualified lead for the sales or used-car team.

Conquest email works best for new inventory and incentive promotions, vehicle acquisition, model-year closeouts and sales events. Individual results vary by market, list and offer.

Service Offers Keep the Service Drive Full

Service email is the most repeatable revenue opportunity in a dealer's email program, because every vehicle on the road needs regular maintenance. Fixed ops brings steady gross profit between vehicle sales, and email reaches customers at exactly the moments they need service.

Effective service emails include:

• Maintenance reminders timed to mileage or months since the last visit.

• Recall notices that bring owners back in and create a chance for additional work.

• Seasonal service specials such as tires, batteries, brakes and winter or summer prep.

• Declined-service follow-ups that remind customers of work recommended on a prior visit.

Every email should link directly to your online service scheduler, so a customer can book an appointment in one click.

Service email gets even stronger alongside a service mailer. Mudd's direct mail service campaigns have shown how much revenue the service drive can generate: one Honda service mailer produced 283 repair orders and $57,435 in service revenue from 1,829 pieces. Following a service mailer with an email gives that same offer a second, clickable touch.

Service visits also feed sales. A customer who keeps coming back for service is far more likely to buy their next vehicle from the same store.

Better Together: Email, Direct Mail and Other Channels

Email delivers its biggest return when it works alongside direct mail, not in place of it. Industry research shows direct mail response improves by 27% when a mailer is followed by an email three to five days later.

The reason is simple. Mail gets noticed: it lands in the customer's hands and often stays on the kitchen counter for days. Email gets the click: it puts the same offer in front of them again, with a button that goes straight to your inventory, trade-in tool or service scheduler. When one household sees one offer in two channels, more of them respond.

Mudd sequences mail and email in three steps:

1. Day 0: the mail drops. A direct mail piece lands with a clear, compelling offer.

2. Days 3 to 5: the email follows. The same offer reaches the inbox while the mailer is still top of mind, reinforcing it instead of competing with it.

3. Customers respond. One click takes them to inventory, a trade-in appraisal or the service scheduler.

The same principle extends to every channel. When email, direct mail and digital advertising all target the same in-market households with matched creative and a consistent offer, each touch makes the next one more effective. A shopper who saw your mailer, then your email, then your display or social ad, has heard one clear message three times.

That coordination is hard to pull off with separate vendors for each channel. It works best when one partner builds the audience, designs the creative, times the drops and reports on sales across all of them.

Best Practices for Dealership Email Campaigns

The dealers who get the most from email follow a handful of consistent practices:

• Give every email one job. Acquisition, inventory, service, lease pull-ahead or a sales event. One clear goal and one clear call to action beat a newsletter that tries to do everything.

• Be specific. Feature real models, stock numbers and savings so shoppers can click straight to the vehicle they want.

• Time it to your mail. Send follow-up email three to five days after a mail drop, while the offer is still fresh.

• Match the creative. Use the same offer, imagery and branding as your mail piece, within your OEM's brand guidelines, so customers recognize it instantly.

• Test subject lines and offers. A/B testing shows what actually gets your customers to open and click.

• Use the right list for the goal. Database email for retention and service, conquest email for growth, or both together.

• Measure sales, not just opens. Matchback reporting connects emails to sold vehicles and repair orders, so you know what the channel actually earned.

Make Email Work Harder for Your Dealership

Email sells cars at nearly the rate of direct mail, keeps your own customers loyal, reaches conquest shoppers at better-than-benchmark rates, fills the service drive and lifts the response of every mail drop it follows.

Mudd Advertising has worked exclusively with car dealerships for 45 years and served more than 10,000 dealers. Our in-house team builds the audience, designs and writes every email to match your mail piece and OEM guidelines, times each send to your campaign, and reports the cars sold matched back to your emails.
