Attachment Limits on Emails
As far as sending various files in the form of photos, documents and spreadsheets, size will always matter. Some free mail accounts used to put limits as far as sending is concerned but not anymore. Today, you can send at most 10MB worth of file sizes to anyone but the next problem would be uploading and downloading them.
For sure, this will drive impatient online users crazy. Apparently, some people just want fast ways of sending and receiving stuff online. But logically, if your file is big, expect waiting time to be a bit delayed. We are not yet that advanced where instant sending can be done.
