What Is Transactional Email Marketing?

Transactional email marketing is the practice of turning automated, event-triggered messages — like order confirmations and shipping updates — into opportunities to deepen customer engagement and drive repeat revenue.

While traditional marketing emails are campaign-based and promotional, transactional emails are functional and expected, triggered by customer actions like purchases, signups, and returns. And because of that, they get opened — a lot. Transactional email campaigns, when thoughtfully put together, can do a lot for your brand.

Why Ecommerce Brands Should Care About Transactional Emails

Here’s the truth: transactional emails (actually all transactional notifications like transactional SMS too) have some of the highest open and click-through rates in all of ecommerce.

Email TypeAverage Open RateAverage Click Rate
Marketing Emails18–25%2–5%
Transactional Emails80–90%20–30%

That means you’re already capturing attention. The question is — what are you doing with it?

Most ecommerce brands use their ESP's default templates. That’s fine… until it isn’t.

Transactional email marketing takes these operational emails and makes them strategic — by turning them into brand moments, conversion opportunities, and retention drivers.

5 Best Practices for Transactional Email Marketing

1. Brand Every Email
Even though it’s triggered by a backend system, every email should feel like your brand wrote it — not your ESP. Use your tone, design, and messaging throughout.

2. Add Value First
Always lead with the core message (e.g. "Your order has shipped"), then thoughtfully layer in promotions, education, or content.

3. Make It Mobile-First
Most customers open these emails on their phone. Keep it readable, clean, and responsive.

4. Drive to a Branded Tracking Experience
Don’t just link to a carrier page. Use a branded tracking page that showcases products, FAQs, and upsells.

5. Analyze & Iterate
Like any good marketing channel, track open rates, click-throughs, and post-click behavior. Then optimize based on what performs.
