Image caching plays a crucial role in email deliverability and the overall effectiveness of email campaigns. Here are some reasons why image caching is important:
Improved Load Times: Cached images load faster, providing a better experience for the recipient. Reduced Server Load: By caching images, the load on the original server is reduced, which can be significant during large-scale campaigns. Consistent Display: Cached images ensure that recipients see the same images, even if the original source is updated or removed.
