Sending emails with large attachments, especially when reaching large batches of recipients, can cause a high server load on the email system. If mass mails are not sent appropriately, they may slow down any sending or receiving of emails of our users, or even result in overall suspension of email service in extreme cases. To help maintain the high quality of email service for the whole University, you should read the guidelines below before composing your mass email messages:
Convert image files from PNG to JPEG format before embedding into the email.
Include links of files, uploaded to CUHK hosting sites, instead of attaching files into the email.
Consider an alternative means of mass communication provided by ITSC, such as Mailing List Service and Mass Mail Service.
Provide receipients with a channel to
Enquire about the message content and
Remove them from receiving similar promotional messages.
When emailing a distribution list,
Observe the attachment size (including email content and attachment). Sending to a distribution list with more than 50 recipients should have size less than 5MB.
Dispatch the email during non-office hours to avoid imposing a heavy load on the email system.
