Frequently Asked Question

Listed below are some sending and receiving limits to be aware of when using Gmail.

Message Size
The maximum size of a message is 25 MB, including all attachments. If your file(s) are greater than 25 MB, Gmail automatically adds a Google Drive link in the email instead of including it as an attachment. Learn more about sending attachments with Gmail and using Google Drive to send attachments.

Attachment Types
Google does not permit sending or receiving executable files (such as files with names that end in ".exe"). This includes executables that have been compressed (zipped) into files such as .zip, .tar, and .tgz.

Number of Recipients

• Using Gmail's web interface, the maximum number of recipients for one message is 500.
• Using Gmail through an email client, the maximum number of recipients for one message is 100.
• If you send messages to more than 300 external recipients in a 24-jour period, your account will be blocked for suspicious activity. You will not be able to send or receive mail until you contact the IT Service Desk. Be aware that LCC email addresses that are set up to forward to external addresses count towards this limit.
• There is no 24-hour limit on the number of messages you can send to LCC addresses that are not set up to forward externally.
• If you need to exceed the Number of Recipients limit, consider using an email distribution list.
