Files greater than 25 MB cannot be attached to emails. Most videos exceed this file size, and so cannot be sent via email.
Videos can be sent via media sharing platforms such as Google Drive or Dropbox. If you have a gmail account, attaching a file that greater than 25 MB size will automatically upload it on Drive and generate a shareable link.
If you do not use gmail, you can sign up and use Dropbox for free. Simply upload the video to Dropbox, get a shareable link, and email the link.
