Now it has become easier by Gmail to send the attachments from 20MB to 25MB. Therefore, we can send and receive the file in size up to 25Megabytes. Another thing to be noted, we are not able to send bigger size of attachments to those who are using other email accounts without facility to send or receive such bigger attachments. Besides, you can invite them to Gmail if your attachment mails bounce.
