HTML Email Guidelines

Follow these best practices for a quick, error-free custom HTML template setup.

At FeedOtter, we’re excited to help you turn your custom HTML email into an automated newsletter. To ensure a smooth setup and high-quality results, it's important to follow the HTML email best practices outlined below.

Acquire a Clean, High-Quality HTML Email File

• Work with your email designer or developer to create a clean, responsive HTML email.

• Test your HTML using a tool like Litmus to ensure compatibility with all major email clients.

• Ensure your logo, footer text, and other static elements are coded in place.

• Use placeholder text and images for areas where blog posts and dynamic content will appear (more on that shortly).

Acceptable sources for your HTML code:

• HTML files exported from your ESP

• HTML direct from your email developer

What NOT to send us:

• EML files or files downloaded from email clients such as Gmail

What Your Email Must Contain (Short Version)

• All images must be visible when your HTML is viewed in a browser.

• All images that should be linked must have anchor tags (links), including article featured image placeholders.

• All text that should be linked must have anchor tags (links), including article placeholder text (titles, "Read More," etc.).

• Your HTML email must be tested using Litmus or another suitable testing tool.

Meeting these requirements ensures our team can provide a timely, high-quality automated newsletter setup.

We cannot accept emails that fail a basic Litmus check or are missing any of the elements outlined above.

If your HTML email meets these criteria, you can start a new setup project with our team here.
