Disclaimer: If you have a Google Workspace account with Rocketspark please refer to this guide: Gmail receiving limits in Google Workspace
The maximum size of a file attachment that you can send with a single email is 50MB on a Rocketspark email account.
The overall storage limit on a Rocketspark Basic email account is 25GB (this includes stored emails in your inbox, outbox etc.).
What if I need to send a file larger than 50MB?
Sending a huge amount of data over an email is not ideal and often very slow. If you need to send an attachment greater than 50MB, we would recommend an online file sharing and storage service such as Dropbox.
