Hi!
You’ve probably used a mailing platform before, probably what is written in this topic’s title. I will tell you a key difference Gmail and Yahoo Mail in this post.
In general, Gmail is the superior platform, because it is arguably more easier to use (I almost wrote “sue” here 
) and more secure than Yahoo Mail. That does not mean that Yahoo is bad though, just that it happens to be much more complex and often users of Yahoo Mail receive tons of scam or threat emails.
