Most e-mail services have size limits, although a few don’t. But even if your e-mail were not to have a size limit, the chances are ... that the receiving e-mail won’t take it, because of the size. So, it’s not only the sending e-mail that a problem, it’s the receiving one that’s the problem too.
And so, if either one (sending or receiving) has a problem, then you have to go outside of e-mail to do it.
The way you go outside of e-mail is that you load the file on some website, where you can provide a “link” to the receiver of your e-mail. That way, they go to the link and download it.
The website can be a service you get, which will then provide you with this ability, or you use your own website, which you might already have through your ISP (most of them give you web space).
The bottom line is, if your mail service won’t handle the size, you have to load it on a website to have the receiver pick it off there. And again, it’s just not “you” the sender who must accommodate the size, it’s the RECEIVER who must accommodate the size!
I hope that helps.
Best advice I’ve seen so far.
