What are the implications of using different types of media (e.g., images, videos, documents) within message templates concerning file size limits and delivery rates?

Using different types of media in message templates carries implications regarding file size limits and delivery rates. WhatsApp imposes file size restrictions on media attachments to ensure optimal performance and prevent abuse. 'Media attachments' include images, videos, and documents included in a message template. Exceeding these limits can cause messages to fail to send. Images and videos generally have stricter size limits than documents, often a few megabytes. Larger files may need to be compressed or hosted externally, with a link shared in the template. Secondly, delivery rates can be affected by media type and size. Larger files take longer to download, especially on slower network connections. This can lead to lower delivery rates and delayed message delivery, particularly in regions with limited bandwidth. Thirdly, different media types may have varying levels of support across different devices and operating systems. Ensure that the media types used are widely supported to avoid compatibility issues. Fourthly, the use of certain media types may be subject to additional scrutiny by WhatsApp's content moderation policies. For example, videos containing inappropriate content may be flagged and rejected. Finally, consider the user experience. While rich media can enhance engagement, avoid overloading messages with excessive media, which can be perceived as intrusive or annoying. For instance, sending an order confirmation with a high-resolution image might improve the experience, but a large video that takes a long time to download would be less effective. File size limits are designed to promote the proper use of images, videos, and documents.
