Google has bumped up the attachment size limit for emails that you receive from 25MB to 50MB. However, the sending size limit for Gmail has not changed. Here's what you need to know.
The previous total attachment size limit for incoming and outgoing emails was 25MB. Now the incoming attachment size limit has increased to 50MB. However, Google has kept the outgoing email attachment size limit at 25MB. If you try to send more than 25MB worth of attachments in one go, you will be prompted to upload files to Google Drive and share them through the cloud storage service instead.
Google expects to complete a full rollout of this feature in the next three days.
