Email Marketing Templates: How to Write Emails That Actually Convert

People have been calling email “dead” for over two decades. If that were true, it would’ve vanished by now. Instead, email remains one of the few channels that consistently delivers measurable returns. Omnisend’s 2025 E-Commerce Marketing Report found automated emails made up just 2% of all volume, yet drove a massive 37% of total email-driven sales. Now, that’s a headliner.

And the reason is simple: automation works. Flows like welcome sequences, cart recovery, and reactivation aren’t just convenient. They get results. Omnisend reports they deliver 52% higher open rates, 332% more clicks, and more than 20 times the conversions compared to manual campaigns. Those kinds of gains are what separate “just sending emails” from actually driving revenue. (Source: Omnisend)

Reliability Isn’t the Same as Performance

Owning your own email list is a huge advantage. Unlike social media or paid ads, nobody can take it away overnight. However, possession doesn’t equal engagement. Just because you can reach people doesn’t mean they’re reading or clicking.

HubSpot’s 2025 benchmark shows average open rates hover around 42%. Open rates below that usually point to issues, such as weak subject lines, bad timing, or an unengaged list. And with most people getting over 100 emails a day, your message has only seconds to stand out before it’s ignored. (Source: HubSpot)

Benchmarks aren’t about chasing vanity numbers. They’re reality checks. They show you where to improve. If you’re lagging, take it as a sign to sharpen your subject lines, trim your list, or rethink when you send. The goal isn’t to brag about a percentage, it’s to actually get noticed.

Your First Chance: Subject Lines

Most emails never get read, and the subject line usually decides the outcome. You only have a few seconds to earn attention, which is why relevance consistently outperforms clever wordplay.

The data backs this up. Experian found that personalized subject lines can drive up to six times more transactions. People respond when an email feels like it was written specifically for them. This matters even more on mobile, where the majority of email opens happen. OptinMonster notes that nearly half of users delete emails that don’t display properly on their phones. If your subject line gets cut off or your preview text fails to add value, your message is lost before it even begins.

This is why subject lines must be clear, relevant, and strategically crafted. They set the tone, determine whether the rest of your email gets read, and shape the first impression of your brand in a crowded inbox. The most effective subject lines are:

• Clear, not cryptic – tell the reader exactly what they’ll get if they open.

• Urgent, but not desperate – create a reason to act now without sounding gimmicky.

• Personalized and contextual – tie the message to behavior, history, or timing.

• Tested, not assumed – run A/B tests to see what resonates with your audience instead of guessing.

If you think of subject lines as headlines for your brand, you stop treating them as an afterthought. Every open begins here. And without the open, nothing else in your email matters.

From Open to Action: The Role of Templates

Getting someone to open an email is only half the battle. The real test comes next: does the template make it easy to act, or does it leave people drifting away? It determines what happens next.

Abandoned cart emails show just how effective a focused template can be. Omnisend’s data reveals that when a customer clicks a cart recovery message, about 42% of those clicks result in a conversion or completed purchase. On average, abandoned cart campaigns deliver conversion rates around 2.7%, well above the performance of typical promotional blasts. This is possible as these emails reach customers at the point of intent and make it easy to finish what they already started.

The most effective templates share a common structure:

• Urgency in the subject line – a nudge that the item may not be there forever.

• Reassurance in the body – highlighting what’s at stake (availability, savings, or convenience).

• One clear call-to-action – a single button that takes them directly back to their cart.

There are no distractions. The simplicity is deliberate. Effective templates don’t overwhelm with fancy visuals or multiple options. They simplify the path forward and remove friction. And when every part of the design works toward the same goal, results follow.

Automation and Testing: The Compounding Effect

Automation gives you the scale to reach people consistently, but testing is what keeps things from going flat. Together, they turn email into a channel that compounds gains over time.

Omnisend’s 2025 report shows it clearly. Automated flows beat manual campaigns on opens, clicks, and conversions. Testing pushes those results even further. EmailMonday found that regular A/B testing can lift ROI by more than 80%. The changes don’t have to be big. You may start with a new subject line, a different send time, or a button tweak, and it can all make a difference. Over time, those small adjustments add up to a framework tailored to your audience , not assumptions, which is an edge your competitors can’t replicate.

Breaking Out of Stagnation

Most companies don’t have a broken email program. Rather, they have a stagnant one. They push out the same newsletter each month, check the box, and then wonder why performance declines.

The brands that separate themselves take a different approach. They design emails as part of a system, not a schedule. They build around customer behavior instead of dates on a calendar. They design mobile-first, ensuring every subject line, image, and CTA works on the device people actually use. They automate, so messages reach the right person at the right moment, and they test continuously to sharpen results. In this model, templates aren’t just visuals, they’re the blueprint that makes the entire system scalable.
