Does your business send out emails confirming an order, password recovery, membership renewal, and similar messages to your customers? Every day, businesses worldwide send out thousands of such emails, most of which are clicked, opened, and read.

These emails, if optimized, can provide powerful marketing opportunities to your business. Here we are discussing transactional emails and how you can harness the ones you send out for your business's benefit. But first, the basics.

What is a Transactional Email?

Also referred to as "triggered email," transactional emails are action-triggered emails that businesses have to send to a recipient pertaining to a transaction or interaction. We call them transactional because these messages are triggered when a customer or a prospect transacts or interacts with an app or a website. Confirmation emails, password recovery emails, invoice emails, etc., are some common examples.

What are the benefits of Transactional Emails?

Though transactional emails are different from marketing emails, these emails carry quite some potential for businesses. Here's how:

1. Boosting conversion

These are the messages that your customer considers a must-open in response to an ongoing transaction with your business. That's why these emails have 8 times more open and engagement rate than your usual marketing emails, all of which provide a solid ground for more conversion for your business.

2. Developing customer trust

Transactional emails provide your customers with important confirmation and communication throughout their buying journey. And so, these emails eliminate your customers' doubts and address their concerns at different touchpoints during the transactions, thereby helping them trust your brand for its exceptional cooperation and communication.

3. Improving brand recognition

Another benefit of transactional emails is that you can plant your brand's visuals and elements in your prospects' minds through these one-off messages. When they see your logo, colors, typography, etc., often, it'll be easier for them to remember your brand in the future.

4. Timing

One of the best benefits of transactional emails is that they are sent in real-time, which means that with effective email marketing, you can prompt the user to take any action and even turn them into buyers.

5. Relevance

With the help of transactional emails, you can garner behavioral data that’ll help you gain more perspective on how your user is responding. You can then create personalised emails that adds real value to the emails that you send out to your segmented customers and have them interact with your brand.
