Beyond Receipts: Transform Transactional Emails into Profit Machines

Every business sends transactional emails, but almost none of them maximize their potential. That’s a crime—and it’s costing you.

Transactional emails are those helpful emails your customers receive after purchasing your product or service or completing any other specific action. They are the confirmation they’ve followed through on all the necessary steps to do what they came to do. Most importantly, customers expect it these days, or they’ll assume something went wrong and lose trust in your website.

These emails aren’t JUST receipts or confirmations; they’re untapped profit machines. If you’re not using them to convert, you’re leaving money on the table—and letting your competitors snatch it up.

I’ve written a lot of direct mail marketing books in my decades of experience in the business. Most predate transactional emails, but all the strategies remain and apply to these email confirmations.

Below, I’ll show you how to use my timeless advice on transactional email so you don’t just confirm—you convert. Let’s look at how you can apply some of my 10 Commandments of Direct Response Marketing from my “No B.S. Marketing” book to transactional emails.

Transactional emails aren’t just about confirming a purchase—they’re about starting a conversation. Use them to tell a story. Personalize them with the customer’s name and purchase.

Done right, these emails say, ‘We care about you,’ not ‘Thanks for your money.’

Connect with your customers. Don’t just talk at them. Chat with them to build a relationship and earn their trust. Build trust, and you’ll build a loyal customer base.

Don’t just send one email. Send many emails spaced far enough apart that you don’t come off as spammy. Include helpful information so they don’t feel like they’re dollar signs to you.

Tell a story. Tell your brand story to become personable, or tell a user’s point-of-view story to showcase how your product or service helps in everyday life. You’ll connect to an emotion in them that wonders if they did the right things or made the right choice by buying your product.

Include a link or button for them to provide their feedback or success story. Make it easy for them to reach a human in your company, whether that’s a customer service or success representative.

Every transactional email is an opportunity to sell again. Include a call to action—always.

Whether it’s an upsell, cross-sell, or a simple reminder to check out your latest offering, make it clear, compelling, and impossible to ignore. Remember, a transaction is the beginning of the customer journey—not the end.

However, stay compliant with FTC rules and consider your customers’ points of view. Make this email primarily informational and less commercial.

Send a “thank you” email after a customer’s purchase. Upsell, cross-sell, and encourage repeat buying at the end of your emails, whether that transactional email is a receipt, shipping notice, or order confirmation.

It’s always a good idea to include validation from previous customers.

Let your happy customers do the selling for you. A short, punchy testimonial in a transactional email turns second-guessers into believers. 'Here’s what others are saying about their purchase' isn’t just validation—it’s persuasion. Use it to stamp out buyer’s remorse and fuel excitement for what’s next.

Why should you include a testimonial when the person receiving the transactional email has likely just purchased from you? Doing so builds trust and encourages repeat business.

How do you get more testimonials? Send a separate follow-up email (not the transactional email) asking for it. Tie a reward to leaving a review if your follow-up emails produce none, like a discount on their next order within so many days.

Include a line that goes something like “Here’s what others have to say about [insert purchase].” Include a short testimonial or two from satisfied customers.

Make it easy—no, make it effortless—for customers to reach you. Phone, email, chat, smoke signals—offer every option they might want. When customers feel heard and valued, they buy more, stay longer, and rave about your business to anyone who’ll listen.

Include your business phone number and a variety of ways to get in touch with your business in the footer of your email or within the copy. Include working links to online forms or purchase pages.

Don’t get comfortable. What works today might flop tomorrow.

Treat your transactional emails like a perpetual experiment. Test everything—subject lines, CTAs, design. Data doesn’t lie, and even small tweaks can drive big profits.

The worst mistake you can make? Thinking you’ve already nailed it. Tweak the copy, calls to action, or design elements so that your customers remain intrigued by you.

Test smart. Split-test your changes to see what elements perform better.

Transactional emails confirm purchases. But why stop there when they can also convert? Every email you send should serve a dual purpose: reassure your customer and push them toward their next action.

Think of it this way: If your transactional emails aren’t making you money, they’re wasting their potential—and yours.

Don’t settle for mere confirmation. Turn any communication, including a transactional email, into a conversion machine using my direct mail marketing advice. My direct mail marketing strategies apply to these emails just as much as to direct mail.

➢ Use transactional emails to continue building relationships with your customers.
➢ Always include an offer and a clear call to action for your customer to do something that helps your business earn more money.
➢ Personalize your communication with your customer even while using automated technology.
➢ Capture and use testimonials and reviews to reassure your customers that they made an excellent decision.
➢ Provide several ways for your customers to reach out to you.
➢ Never get too comfortable with your email design. Keep revising and testing.
