Understanding Substack Email Headers

Purpose of Email Headers

Substack email headers are an important component of any newsletter. They provide context for the reader and help establish a connection between the sender and the recipient. The purpose of a Substack email header is to give the reader a brief overview of what the newsletter is about and what they can expect to find inside. It should also include information about the sender, such as their name and contact details.

A well-crafted Substack email header can help increase the open rate of your newsletters, as it gives the reader a reason to open the email and read further. It also helps build trust and credibility with your audience, as it shows that you are a legitimate sender and not a spammer.

Components of a Substack Header

A Substack email header typically consists of several components. These include the subject line, sender name, sender email address, and any additional branding or design elements. The subject line should be concise and informative, giving the reader a clear idea of what the email is about. The sender name and email address should be easily recognizable and should match the name and email address associated with your Substack account.

In addition to these basic components, Substack email headers can also include additional branding or design elements, such as a logo or banner image. These elements can help establish a consistent brand identity and make your newsletters more visually appealing to your readers.

Overall, a well-crafted Substack email header can help increase the effectiveness of your newsletters and establish a strong connection with your audience. By taking the time to craft a compelling header, you can help ensure that your newsletters are read and engaged with by your subscribers.

Designing Your Substack Header

Creating a visually appealing email header can be the difference between a subscriber clicking on your newsletter or skipping over it. In this section, we’ll cover some key elements to consider when designing your Substack header.

Visual Elements

Your header should be eye-catching and easily recognizable. Consider using your publication’s logo or a unique font to make your header stand out. You can also add images or graphics to make your header more visually appealing.

Branding Consistency

Consistency is key when it comes to branding. Make sure your header aligns with your publication’s overall branding and messaging. This includes using the same color scheme, font, and tone of voice.

Header Size and Layout

Your header should be sized appropriately and have a clear layout. It should be easy to read and not cluttered with too much information. Consider using a hierarchy of information, with the most important information at the top and less important information at the bottom.

In summary, designing a Substack header that is visually appealing, consistent with your branding, and has a clear layout is crucial for engaging your subscribers. By considering these key elements, you can create a header that stands out and encourages your readers to engage with your newsletter.

Technical Aspects of Email Headers

HTML vs Plain Text

When it comes to Substack email headers, there are two main formats to choose from: HTML and plain text. HTML headers offer a more visually appealing and customizable design, with the ability to include images, colors, and different font styles. Plain text headers, on the other hand, are simpler and more straightforward, with no frills or distractions.

While HTML headers may seem like the obvious choice, it is important to consider that some email clients may not support HTML formatting, resulting in a broken or distorted header. In contrast, plain text headers are universally supported and will always display correctly.

Responsive Design

Another important aspect of Substack email headers is responsive design. With more and more people accessing emails on their mobile devices, it is crucial that email headers are optimized for smaller screens. This means using a responsive design that adjusts the layout and formatting of the header to fit the screen size of the device it is being viewed on.

By using responsive design, Substack email headers will not only look better on mobile devices, but they will also be easier to read and navigate, resulting in a better user experience for subscribers.

Header Optimization

Finally, optimizing Substack email headers is essential for ensuring that they are effective in capturing the attention of subscribers and encouraging them to open and engage with the email. Some key elements to consider when optimizing email headers include:

  • Clear and concise subject lines that accurately convey the content of the email
  • Personalization, such as using the subscriber’s name or location in the header
  • A visually appealing design that reflects the brand and style of the publication
  • A clear call-to-action that encourages subscribers to take action, such as clicking a link or upgrading to a paid subscription

By optimizing Substack email headers, publishers can increase open rates, engagement, and ultimately, the success of their email campaigns.

Content Strategy for Headers

When it comes to creating email headers, it’s important to have a clear content strategy in place. By doing so, you can ensure that your headers are personalized, relevant, and engaging. Here are a few key considerations to keep in mind:


Personalization is key when it comes to email headers. By addressing your readers by name, you can create a sense of connection and make them feel valued. You can also use personalization to tailor your headers to specific segments of your audience, based on their interests, behaviors, or location.

Clarity and Relevance

Your headers should be clear and relevant, so that readers know exactly what to expect from your email. Make sure that your header accurately reflects the content of your email, and avoid using clickbait or misleading language. It’s also important to keep your headers concise and to the point, so that readers can quickly understand what your email is about.

Engagement Triggers

Finally, your headers should include engagement triggers that encourage readers to take action. This might include a call-to-action (CTA) button, a discount code, or a teaser for exclusive content. By giving readers a reason to engage with your email, you can increase open rates, click-through rates, and overall engagement.

Overall, a successful email header content strategy should focus on personalization, clarity and relevance, and engagement triggers. By keeping these key considerations in mind, you can create headers that resonate with your audience and drive results.

Testing and Analytics

A/B Testing Headers

One of the most effective ways to optimize email headers is through A/B testing. This process involves creating two different versions of a header and sending them to a small sample of your subscribers. You can then analyze the performance of each header to determine which one resonates better with your audience.

To conduct A/B testing, you can use Substack’s built-in testing feature. This allows you to create two different headers and send them to a small percentage of your subscribers. Once you have enough data, you can then choose the winning header and send it to the rest of your subscribers.

Analyzing Header Performance

Analyzing the performance of your email headers is crucial to improving your email marketing strategy. Substack provides analytics that allow you to track the open rates and click-through rates of your emails. You can use this data to determine which headers are performing well and which ones need improvement.

To access your email analytics, navigate to the “Subscribers” tab in your Substack dashboard and click on “Emails.” Here, you can view the open rates and click-through rates of each email you’ve sent. You can also view the performance of individual headers by creating segments based on the header used.

By analyzing the performance of your email headers and conducting A/B testing, you can improve the effectiveness of your email marketing strategy and increase engagement with your subscribers.

Best Practices for Substack Email Headers

When it comes to creating effective email headers for Substack newsletters, there are a few best practices to keep in mind. By following these guidelines, creators can create headers that are consistent, simple, and include a clear call to action.


One of the most important aspects of creating a successful email header is consistency. Subscribers should be able to easily recognize your newsletter by its header, so it’s important to keep it consistent across all emails. This means using the same font, color scheme, and logo in each email header.


Another key component of an effective Substack email header is simplicity. The header should be easy to read and understand at a glance, so it’s important to keep it simple and straightforward. This means avoiding overly complicated designs and using clear, concise language.

Call to Action

Finally, it’s important to include a clear call to action in your Substack email header. This can be as simple as encouraging subscribers to read the latest issue of your newsletter, or as specific as asking them to share your newsletter with their friends and followers. By including a call to action in your header, you can encourage subscribers to engage with your newsletter and help grow your audience.

In summary, creating effective Substack email headers requires consistency, simplicity, and a clear call to action. By following these best practices, creators can create headers that are both visually appealing and effective at engaging subscribers.

Common Mistakes to Avoid

When it comes to creating a Substack email header, there are a few common mistakes that writers should avoid. These mistakes can make your header less effective and could even lead to readers unsubscribing from your newsletter.


One of the biggest mistakes that writers make is overcrowding their email header. While it’s important to include key information like your newsletter name and logo, too much text or too many images can be overwhelming for readers. This can make your header look cluttered and unprofessional, and may even cause readers to delete your email without reading it.

To avoid overcrowding your header, focus on including only the most important information. Use clear, concise language and limit yourself to one or two images at most. Consider using a table or list to organize your information in a way that’s easy to read and understand.

Neglecting Mobile Users

Another common mistake is neglecting mobile users. With more and more people accessing their email on their phones, it’s important to make sure that your header is optimized for mobile devices. If your header is too large or too cluttered, it may not display properly on a mobile screen, making it difficult for readers to engage with your content.

To avoid neglecting mobile users, test your header on different devices and make sure that it looks good on both desktop and mobile screens. Keep in mind that mobile screens are smaller, so you may need to simplify your header or use a different layout to make it more mobile-friendly.

Ignoring Brand Guidelines

Finally, ignoring brand guidelines is another mistake that writers should avoid. Your Substack email header is an important part of your brand identity, and it’s important to make sure that it reflects your brand’s values and personality. If your header doesn’t match your brand guidelines, it can confuse readers and make it harder for them to connect with your content.

To avoid ignoring brand guidelines, make sure that your header uses the same colors, fonts, and images as your brand’s website and other marketing materials. If you’re not sure what your brand guidelines are, take some time to review your brand’s style guide or consult with a designer. By following your brand’s guidelines, you can create a header that’s consistent with your brand identity and helps to build brand recognition.
