How to Optimize Transactional Emails: 10 Tips for Maximum Impact

Transactional emails are the unsung heroes of your email marketing strategy.

While promotional emails often steal the limelight, transactional emails play a critical role in delivering essential information and nurturing customer relationships.

There are many benefits of transactional emails, but they just don’t get the same appreciation that marketing emails do.

From order confirmations and shipping notifications to password resets and account updates, these emails have a direct impact on user experience, customer satisfaction, and even conversions.

But are you making the most of this valuable communication channel? Are your transactional emails optimized?

Those questions bring up another important question…

What am I optimizing my transactional emails for?

You’d be forgiven for thinking that transactional emails are just a way to react to a customer’s action, but they can be so much more than that.

Transactional emails are a great way to nurture customer relationships, mainly because you aren’t reaching out to the customer unprompted.

Unsolicited marketing emails can turn customers off to your brand, but since transactional emails are triggered by actions taken by the customer, they are expecting your communication and most likely want to see your email in their inbox.

Because of that, transactional emails are prime real estate for marketing, even if they aren’t being sent with the intent of marketing in the first place.

As transactional emails tend to have higher open rates than marketing emails, you can get more eyes on your marketing material or anything else you want customers to see by including some of that material in your transactional emails along with whatever pertinent information the customer needs.

In short, transactional emails will generally have higher open rates than your marketing emails, and you can take advantage of that valuable virtual real estate to increase brand awareness, upsell or cross-sell your customers, and much more which I’ll mention below.

Now that you know why you should optimize your transactional emails, here are 10 tips to optimize transactional emails for maximum impact.

1. Provide Relevant Information

This one is pretty intuitive; include all necessary details related to the transaction.

For example, if a customer makes a purchase, include order confirmation, shipping information, and expected delivery dates. Additionally, anticipate common customer questions and address them proactively.

2. Personalize the Content

Again, a fairly standard practice: use dynamic tags to insert personalized information into your messages, like the recipient’s name, order details, or account information.

Personalization increases customer interaction and engagement and, in combination with transactional emails generally being opened more often than marketing emails, you can get high open rates on any marketing content you might add to your transactional emails.

3. Optimize Subject Lines

The best way to get people to click on your transactional emails is to be as clear as possible with the purpose of your email.

Create concise and compelling subject lines that clearly convey the purpose of the email, and incorporate relevant keywords to improve visibility and click-through rates.

4. Ensure Email Deliverability

This one is very dependent on your transactional email service provider, and their associated deliverability rates.

Personally, I recommend MailerSend by MailerLite for its high deliverability rates.

If your email deliverability is failing then there are some customers who just won’t receive your transactional emails, which is a great way to reduce customer trust in your brand.

5. Use a Clear Call-to-Action (CTA)

Particularly if you’re upselling or cross-selling your customer after they’ve made a purchase, clearly indicate the desired action you want recipients to take. Use contrasting colors, prominent buttons, and persuasive language to encourage clicks and conversions.

If a customer has made a purchase with your brand and is satisfied with that purchase, chances are they’ll come back to you.

You can expedite that process by presenting your customers with upsells or cross-sells in your post-purchase emails.

6. Mobile Responsiveness

According to SuperOffice, as of October 20, 2022, 81% of all emails are now opened and read on mobile devices. Thus, if your emails are poorly formatted or non-responsive on mobile devices, then you won’t leave a great impression on your audience.

Ensure the email layout and font sizes are mobile-friendly and easy to read.

7. Brand Consistency

Considering how many people will see your transactional emails, you’ll want to put some serious effort into making sure they aesthetically align with your brand’s image.

Use your company logo, colors, and typography to reinforce brand recognition and trust.

The more that those things are seen by a customer, the more your brand identity will be reinforced in their minds.

8. Keep Emails Concise and Scannable

Transactional emails should be clear and to the point.

Use bullet points, headings, and short paragraphs to make it easy for recipients to scan and understand the information quickly.

9. Add Social Sharing Options

Encourage recipients to share their positive experiences on social media platforms by including social sharing buttons. This can increase brand visibility and potentially attract new customers.

10. Monitor and Analyze Performance

Use email analytics to track the performance of your transactional emails. Measure open rates, click-through rates, and conversion rates to identify areas for improvement and optimize future campaigns.


This isn’t an exhaustive list, and there are likely a handful of other things you could do to fully optimize your transactional emails. However, I hope this article has informed you not only about how you can optimize your transactional emails, but why you should consider doing so in the first place.
