When it comes to email marketing, the use of inline images can greatly enhance the visual appeal and effectiveness of your messages. However, there are certain best practices to follow to ensure that your images display correctly, are user-friendly, and comply with email standards and regulations. Here are 17 best practices for using inline images in Mailgun emails.

1. Optimize Image Size

Large images can slow down email loading times, frustrating recipients. Always compress and optimize your images for web use, ensuring they strike a balance between quality and file size.

2. Use the Right Format

Choose the most suitable image format. JPEGs are great for photographs, while PNGs offer better transparency options. GIFs are ideal for simple graphics or animations.

3. Inline or Attached?

Understand the difference between inlining an image (embedding it directly in the email body) and attaching it as a separate file. Inlining is generally preferred for a seamless user experience.

4. Alt Text Is Key

Always include alternative text (alt text) for your images. This not only helps with accessibility but also ensures that recipients can understand the image content if it fails to load.

5. Consider Mobile Devices

With mobile email usage on the rise, ensure that your images are responsive and display correctly on various screen sizes.

6. Avoid Spam Filters

Excessive or poorly implemented images can trigger spam filters. Use a balanced ratio of text to images and avoid using too many large images.

7. Link Images Strategically

If you're linking images to external URLs, ensure that the links are relevant, trustworthy, and add value to the recipient's experience.

8. Test, Test, Test

Send test emails to yourself and colleagues to check how the images appear in different email clients and devices.

9. Use a Reliable Email Service

Utilize a trusted email service like Mailgun that supports high-quality image handling and delivery.

10. Follow CAN-SPAM Act

Ensure that your email marketing practices, including the use of images, comply with the CAN-SPAM Act to avoid legal issues.

Maintain brand consistency by using images that align with your brand's visual identity.

12. Clear Call to Action

If your image includes a call to action, make sure it's clear, concise, and easy to understand.

13. Avoid Stock Images

Generic stock images can make your emails look impersonal. Use original, high-quality images that resonate with your target audience.

14. Accessible Design

Ensure that your email design, including images, is accessible to all users, including those with visual impairments.

15. Balance Creativity with Simplicity

While creativity is encouraged, don't overcrowd your emails with too many images or complex designs. Simplicity often leads to better engagement.

16. Track and Analyze

Utilize email tracking tools to analyze how recipients interact with your images, and use this data to optimize future campaigns.

Keep abreast of the latest email marketing trends and best practices, especially regarding image use, to ensure your campaigns remain effective.
