Message size limit

You can send and receive emails up to 25MB in size with Yahoo Mail.

This means that the total encoded size of the email message you're sending can't exceed 25MB. Attachments sent with emails have to be encoded into a format other email programs can read. This encoding adds about 33% to the original size of the attachment. So a 1.5MB attachment will end up being about 2MB after encoding.

Keeping your emails, attachments and all, under 25MB will help make sure they get where you want them to go quickly.
