Hello,
We experienced an email loading time issue that is different from each mail providers. We already tried to optimize the image (under 5MB), but the performance still not optimal. We have some questions regarding the email image attachment backend process in Dynamics 365 Marketing :
Thank you,
Gogo
Thank you for your question. The recommended size of image asset for optimal performance is less than 1MB. Performance is a complex topic that is dependant also on the internet connection of the end recipient, the type of device and more.
Overall, assets are stored in either Azure Blob Storage or Dataverse (based on number of conditions) and served using CDN for the best performance. The end recipient will then be able to access the image via image links that are generated and given these are served using CDN, they are publicly available and no authentication mechanism is needed.
If you need any further help, please reach out to us via support.
Thanks,
Tereza Kirk

Hi Gogo,
Do you mean the images and videos which has already been inserted into a marketing email?
The images in Files are stored in dataverse (msdyncrm_file entity).
