In other words, files that can be sent as attachments can not be sent over 25MB in size. If you send attachments in the traditional way, if the contents are incorrect after the send, or if the sent attachments are modified, you have to resend them.
However, with GMail, attachments can be sent as links via Google Drive.
The original file exists in my Google Drive and only the link information of that file is sent. This allows G Suite users to send links up to 5TB.
I upload all attachments on the drive and send them in a link. In particular, PDF files and MS Office document files will be sent by this link method. Sometimes, after sending a link to an MS Office document or a PDF file, the originals may be wrong and you may need to resend the revision.
In the old days, you would need to modify the file and send it back to the recipients, but with version control in Google Drive, you can use version control to add the latest version of the file to the document Just upload.
When sending attachments from Gmail, send them via Google Drive as in the image above.
Like PDF documents, non-Google document formats on Google Drive can take advantage of version control. You can upload and maintain multiple versions of a document. These documents, which are delivered as links, will maintain the latest version of the document if the uploaded version of the file is uploaded without any changes to the link.
