One of the biggest challenges of using email attachments is the file size limit. Most email providers have a maximum limit of 25 MB per email, which means that you may not be able to send large or multiple attachments at once. This can cause frustration, delay, or rejection for both you and your recipients. To avoid this problem, you should optimize the file size of your attachments, by reducing the resolution, quality, or length of your content, or by using compression tools or online services that can shrink your files without compromising their quality. You can also use alternative methods, such as cloud storage, file sharing platforms, or online portfolios, that can host your files and provide a link to access them. Optimizing the file size will help you ensure a smooth and fast delivery and reception of your attachments.
