Let’s get to it!

What Are Transactional Emails?

Before we delve into the details, let’s start with some definitions.

Transactional emails are the emails that are triggered by a specific action or event on your website. They are an essential medium of communication for any successful WordPress business.

WordPress site owners and developers will recognize common transactional emails such as new order emails, processing order emails and password reset emails amongst others.

Unlike promotional emails and email marketing campaigns, which are sent to a large group of subscribers, transactional emails are highly targeted and personalized. They are crucial for providing customers with important information and updates about their orders/accounts. Additionally, they help you and your customers maintain a record and build trust and loyalty for your brand.

For WordPress site owners and developers, it is important to have a reliable system in place for sending transactional emails. In the next section, we’ll talk about why that’s the case and how your transactional emails can help you improve your bottom line.

The Importance of Transactional Emails for WordPress

Transactional emails are not just a formality for WordPress businesses. They play a crucial role in the overall customer experience and can directly impact your bottom line. Here are some reasons why transactional emails are important for every WordPress business.

1. Provide Information to Customers

As mentioned earlier, transactional emails are triggered by specific actions or events, such as a purchase confirmation or shipping update. These emails provide customers with important information about their orders, such as order details and tracking numbers. This helps to keep customers informed and reduces the number of inquiries and complaints about their orders.

2. Create a Record

Transactional emails serve as a record for you and your customers to refer back to in case of any discrepancies, miscommunications or mishaps. These emails play a crucial role in maintaining a clear and reliable channel of communication between you and your customers, ensuring that both parties can easily access vital information whenever required.

3. Build Trust and Loyalty

Transactional emails are highly targeted and personalized, making them a great opportunity to build trust and loyalty with your customers. By providing them with timely and relevant information, you are showing that you value their business and are committed to providing a positive customer experience. This can lead to repeat purchases and positive word-of-mouth recommendations.

In addition, these emails also provide an opportunity to reinforce your brand identity. By ensuring that your transactional emails are consistent with your brand’s look and feel, you can create a cohesive and memorable brand experience for your customers. This can help to increase brand recognition and loyalty, leading to higher customer retention rates.

4. Upsell and Cross-sell Opportunities

WooCommerce businesses can also use transactional emails as a marketing tool to upsell and cross-sell products to customers. For example, a shipping notification email can include a section showcasing related products or a discount code for their next purchase. This can help to increase sales and customer lifetime value.

Furthermore, you can use these emails to promote other aspects of your business, such as your loyalty program or upcoming sales events. By integrating marketing messages into your transactional emails, you can leverage these communications to drive additional revenue and engagement from your customers.

5. Reduce Customer Support Tickets

Savvy WordPress business owners can use transactional emails to provide customers with additional information about their products, services and support. Including information such as return policies, sales terms, customer support contact details, and more can not only enhance the customer experience but also reduces the burden on your customer service team.

Why Aren’t My Transactional Emails Reaching My Customers?

That’s the million dollar EBITDA question, isn’t it?

In all likelihood, if you aren’t already using a dedicated email plugin, the reason that your transactional emails have been circling the cyberspace equivalent of a blackhole is simple: rate-limiting.

Your WordPress web host is focused on “housing” your website. You wouldn’t want your real estate agent delivering your mail, now would you? Even the very best WordPress website hosting services such as WPEngine and DreamHost, will limit the number, size and frequency of emails you can send.

That’s why you need a dedicated email plugin to ensure deliverability in a timely manner. In the next section, we’ll introduce you to the very best email service providers for WordPress so that your emails never end up in the spam folder.

My Transactional Emails Still Aren’t Reaching My Customers

If you’ve gotten a dedicated email service provider and your emails still are not getting to your customers’ inbox, don’t panic. There are any number of (simple) reasons why your transactional emails might still be landing in the junk box.

Let’s take a quick look at some of the simplest (but most often overlooked) reasons why your emails aren’t reaching their target, even after you’ve gotten a dedicated email service provider.

  1. Invalid Email Addresses

    When customers provide incorrect or invalid email addresses, your emails will fail to reach them. To tackle this issue, you can incorporate email validation during the registration and/or checkout process and encourage customers to verify their email addresses.

  2. Email Settings

    From your WordPress Admin account, ensure that you have the right settings for your transactional emails. If you’re using an ecommerce platform like WooCommerce, simply navigate to WooCommerce > Settings > Emails from your WordPress Admin Sidebar and click Manage next to each type of email.

  3. Content

    Review the content of your emails to ensure they don’t violate the email content guidelines of your host, CRM, or email service provider. Including too many links or suspicious links (i.e., links that are not associated with your domain) and large files like JS files may also cause your email service provider to flag the content.

  4. Compliance

    Ensure that you comply with email marketing regulations such as the CAN-SPAM Act and GDPR, depending on your target audience. Most CRMs and email service providers make this easy to do, so you shouldn’t have to get a law degree to resolve this issue.

  5. Low Sender Reputation

    Your sender reputation plays a crucial role in email deliverability. To improve your sender reputation: remove invalid and/or inactive email addresses from your list and use double opt-in to confirm email subscriptions.

  6. Email Domain

    Your email’s domain (i.e., the part of the email address that comes after “@”) should match your website’s domain. For example, if your website is “” then the email address from which you send your website’s emails should have the same domain, “”. Mismatched website and email domains are likely to get the attention of your email service provider and land your mail in the spam folder.

  7. Sender and Receiver Emails

    Your sender and receiver emails should not be the same. For example, if you send your website’s emails from “”, you should not also receive emails with this address. Most websites receive emails through their “support” handle unless they are going to a specific individual within the organization.

Run Your Email Campaigns with Uncanny Automator

Now that you have a dedicated email service provider, you can send out important email blasts to all of your contacts with absolute confidence. However, managing those emails at scale and getting them to fit into your existing website infrastructure and workflows is the next challenge you’ll face.
