Google mail is better than Yahoo Mail and Hotmail

I scanned all the documents needed for house loan and zipped them into one single zip file - about 15MB.Then, I tried to use Yahoo Mail to send the zip file to bank agents. Unfortunately, I failed to upload the file to Yahoo Mail. If I am not mistaken, Yahoo Mail has limit on file size for its free mail service. I change to use Google Mail. The uploading is very fast. I managed to send the file.
