What is the maximum email size in Gmail?
Gmail maximum email size is 20MB (Megabytes)
This includes attachment also. Though they say 20MB you cannot attach a file exactly for 20MB. All the email providers encrypt the files attached with your email, so it will take another 1 MB or so.
So the real attachment size would anywhere around 18 to 19 MB
Yahoo only allows to attach 10MB
