Email design is notoriously difficult due to Varying support across clients like Outlook, Gmail, and Apple Mail. Base64 encoding offers a unique solution for ensuring your visual elements render correctly every time.
Why Use Base64 in Email?
The primary advantage is that the image data is embedded within the email's HTML. This means the client doesn't need to make an external request to load the image.
Advantages:
- Bypass Image Blocking: Display logos and icons instantly.
- No Broken Links: The image travels with the email.
- Offline Viewing: Users can see the visuals even without an internet connection.
When to Avoid Base64 in Email
