That’s a lot of transactional emails!

8 transactional email examples #

Transactional email is a type of one-to-one, automated email a business sends to an individual user after a specific trigger or event such as a new sign-up, a password reset request, or an online purchase (unlike bulk or marketing emails, where the same message is distributed to an entire email list simultaneously).

Depending on the shape of your business, there may be dozens of transactional emails you can send, but a few must-haves include:
1. Welcome email
2. User invitation email
3. Password reset email
4. Payment invoice or receipt email
5. Payment failure notification email
6. Order confirmation email
7. Daily, weekly, and monthly digest emails
8. Enabling 2FA confirmation email

1. Welcome email #

If you ask new customers to sign up for or verify an account, you will probably send them a welcome email as soon as they’re done. You want this email to A) get delivered really quickly, B) be extremely useful, and C) look and feel like it’s coming from your brand: first impressions count.

In our welcome email, which we send out once a Postmark account is approved, we use a dedicated illustration to welcome customers to the Postmark family, offer some information about what they can expect from our service, and share a few useful links that help them reach their account and get started asap.

The subject line: Welcome to the Postmark family

If this was your welcome email → in addition to making your welcome message consistent with your brand tone & style, you could summarize your customers’ main details and list the next steps they should take. For more tips and best practices, check out our welcome email best practices guide.

2. User invitation email #

If you offer customers the option to invite their colleagues or clients to an account, then you’ll need an account invitation email. In our example, we use another dedicated illustration to make the invitation look official, and share the name of the person who invited the recipient.

An example of transactional email: a Postmark email inviting teammates to the account
The subject line: You’ve been invited to Postmark

If this was your account invitation email → you would, like us, make sure to give a clear call to action so the invitee knows what to do to set up their account.

3. Password reset email #

Password reset emails are some of the most succinct and yet helpful emails you can send. They have one simple goal: help a user securely re-establish access to their account.

In our password reset email, we keep our message short and to the point, giving clear instructions about what steps our customers need to follow—and how long the email will be valid for (30 minutes). Note that our email also has a clear “From” name and subject, which helps a customer quickly identify the correct message in their inbox and take action.

An example of transactional email: a Postmark password reset email
The subject line: Postmark password reset

If this was your password reset email → you’d want to make extra sure your email gets delivered super fast, so you need an extremely reliable transactional email service… just like Postmark. 😉 For more info and tips on how to design your password reset emails, check out this really in-depth guide to password email reset best practices.

4. Payment invoice or receipt email #

At some point, your business will need to process payments and send relevant receipts. A well-designed receipt can make a great impression and even help generate additional revenue: in our example, we introduce a separate call to action that recommends a companion service and offers a 14-day free trial.

An example of transactional email: a Postmark payment receipt
The subject line: Your [month] 2022 receipt

If this was your payment receipt email → ​​you’d want to give a useful and valid record of the expense for accounting purposes (for example, attach a printable PDF to your email or give customers access to an online repository they can download it from).

For more tips on how to structure your receipts, this invoice and receipt email best practices guide will be a great starting point.

5. Payment failure notification email #

A common phenomenon faced by all subscription businesses is involuntary churn, when customers fail to pay for a product or service not because they’re unhappy with it, but because of (preventable) payment and billing issues.

At Postmark, we solve this problem with a 3-email dunning sequence that informs our customers of the issue and invites them to solve it within a specific timeframe. Below you see the first email, but you can take a look at our entire dunning sequence to see how we make it work.

An example of transactional email: a Postmark dunning notification
The subject line: Action required: We couldn't process your payment

If this was your payment failure/dunning sequence → you’d want to make sure you give your customers clear directions to change their billing details and ample time to do it—so they can avoid bad surprises like suddenly finding themselves with a suspended account or locked out of it entirely due to a missed payment. Yikes. If you need some inspiration, check out some more examples, tips, and a template to create the perfect dunning sequence.

6. Order confirmation email #

Speaking of payments: sometimes your customers change their plans (...literally!), and you’ll want to notify them when their order has been successful. Whether it’s an upgrade or a downgrade, an order confirmation email like ours below clearly recaps what the customer changed and confirms how their billing cycle/preferences have been updated as a result.

An example of transactional email: a Postmark order confirmation
The subject line: Your new Postmark plan

If this was your plan change notification email → ​​you could give your customers a handy link to their account dashboard where they can see their current usage and costs.

7. Daily, weekly, and monthly digest email #

Digests (sometimes mis-labeled as newsletters) are single emails that summarize account activity during a specified timeframe. For example, we send out a weekly digest that summarizes the number of emails sent, bounced, and that were reported as spam—and we like to see the count stay at 0 for the latter two. 😉

An example of transactional email: a Postmark weekly digest
The subject line: Weekly digest for [business name]

If this was your email digest → ​​you’d want to include relevant data points your customers (and their stakeholders) will find valuable. Instead of requiring them to visit their dashboard every time they want to check on a project’s status or progress, you can conveniently deliver the same information via email. That’s a great service!

8. Enabling 2FA confirmation email #

Sometimes, for extra security, you’ll ask your customers to set up two-factor authentication (2FA). Here at Postmark, we offer this extra layer of account security as well, and once you set up 2FA you will receive an email that confirms you’ve been successful.

An example of transactional email: a Postmark 2FA confirmation message
The subject line: Two-factor authentication enabled

If this was your 2FA confirmation email → ​​ you could send a succinct reminder of the new details your customer shared (e.g. the phone number associated with their account). Bonus points if you like to be extra-safe, like us, and give customers a way to contact support immediately if they received this email without first taking action.
