This is a good undocumented feature for choosing which emails to delete in Gmail: >Gmail supports an undocumented “size” search operator that you can use to quickly find all the big emails in the mailbox whose size exceeds a particular threshold. The search syntax is: >size:[size in bytes] >To give a real example, a Gmail search query like size:5242880 will list all big emails who size is 5 MB or greater while size:10485760 will list email messages that are bigger than 10 MB. >You may specify the size in MB as well which makes it a lot easier. For instance, size:5MB (or say size:5M) will find all Gmail messages that are 5 MB or greater in size. https://www.labnol.org/internet/gmail-size-search/26669/ https://www.labnol.org/internet/gmail-size-search/26669/
