What are transactional emails?

A transactional email is an automated email sent to an individual following a specific action or transaction, such as a purchase or password reset. Unlike promotional emails, transactional emails provide necessary information and updates to the recipient and are exempt from anti-spam laws.

How are transactional emails different from marketing emails?

Transactional emails, such as account registration emails, billing emails, etc., are usually needed for online businesses like eCommerce, SaaS, etc. In comparison, marketing emails sell any product or service for lead conversions.

The content of transactional emails depends on each customer's activity, such as finishing a pending transaction or inquiring about order shipment.

In contrast, marketing emails are used to increase multi-channel engagement for your business, which is why their content can be specific to different audience groups.

7 Transactional email best practices to boost email marketing performance

Here are seven best practices for transactional emails you can employ:

1. Don’t use “no-reply” email addresses

As a customer, there’s nothing more frustrating than having a question in your mind and not knowing where to get it answered. When sending transactional emails from a no-reply email address, you limit your customers’ interactions.

On the other hand, adding a “reply-to email address” offers these two major benefits:

  • It shows customers you welcome any communication and are all ears for what they say.

  • If your customers reply, that email is automatically added to your subscriber list.

2. Provide clear and relevant details

Here are some of the things you should do to ensure transactional emails offer value to the user:

  • Include a clear “from” address. This gives your recipient an idea about the email and helps with inbox management. For example, “” is used to reply to any queries (technical advice, instructions, etc.) users might have.

  • Write a clear and concise subject line telling the user what the email is about. The recommended subject line length is around 60 characters or nine words.

  • Use relevant preheader text to tell the reader further what the emails contain.

3. Safeguard your email message

Avoid potential email breaches and loss of customer trust by safeguarding your emails. You can do that by using these three authentication protocols:

  • Sender policy framework (SPF)

SPF is an email authentication standard that protects you against phishing, spoofing, and spam.

  • Domain keys identified mail signature (DKIM)

DKIM is an email security standard used to ensure messages are not modified while traveling between the recipient and sending servers.

  • Domain-based message, authentication, reporting, and conformance (DMARC)

DMARC is a protocol that builds on DKIM and SPF to tighten the protection of your domain from fraudulent emails.

You should not limit your transactional emails to just confirmation and acknowledgment of interactions with a user. They can also act as a marketing email by updating you on items on your wishlist.

Social media link sharing in a transactional email helps keep your customers engaged after the email is closed. Even if there’s no clear CTA, they could always check your social media profiles for more deals and prices.

Another benefit is that if the recipient is not interested in what you are offering, they might follow your socials to get similar deals in the future.

5. Use a separate domain and IP address

Your transactional emails should be sent from a different domain and IP address than your bulk marketing emails like promotional, cart abandonment, re-engagement, etc.

Why? Marketing emails are more likely to receive complaints and be flagged as spam.

If your transactional emails are sent from the same IP and domain, they may be considered similarly.

While screening emails, whether marketing or transactional, mailbox providers consider domain and IP reputation. If you pick a bad one, your emails will land in promotions or spam folders.

Now, how can you keep your transactional and marketing emails separate? By following these tips:

  • By providing separate IP addresses for transactional and marketing emails. For example, for transactional emails and for marketing emails.

  • Avoid using the same domain or subdomain names for both types of email.

  • Use different servers to send transactional and marketing emails to prevent blacklisting issues.

6. Always include a plain text version of your email

Giving your readers the option of receiving plain text emails rather than image-filled versions is always a smart idea. Your email’s deliverability and accessibility will both increase due to this.

While creating the plain text version, keep in mind that the text and HTML email content should not differ much.

7. Choose a reliable email services provider

There are a lot of transactional email providers out there. So, do a little bit of digging to choose one that fits your needs and gives the quality you need while staying within your budget.

Examine the benefits and drawbacks of each transactional email service you’re considering to find the best fit for your needs.
