Previously, whenever you needed to send heavier documents or images you needed to use Google Drive. When you tried to send a file that’s maybe 5MB or 10Mb, Gmail would prompt you to store the file in Google Drive and then share the link to the file location. That caused problems for many who didn’t want to use cloud storage and would rather send the files as email attachments.
Google these days is prompting more people into using Gmail for business and Gsuite, and inability to send larger files may discourage many from adopting Gsuite.
Considering this, Google has increased the size of files that you can send within your Gmail messages. Now you can send a file of size 50MB in your Gmail messages.
