Hello ScottRoach, and thank you for your question.
Our max email attachment limit is set at 50MB for the total attachment size of your email messages.
Typically email isn't the best medium for large file transfers these days, and you might also want to take a look at collaborative file storage services such as Google Drive, DropBox, or Box, depending on your team's needs.
If you had any other questions at all, please don't hesitate to let us know!

It depends on the email account you have from the service or hosting provider you are using. For most platforms you can have extra plugins from third party organizations that help you send large files. You might also consider cloud hosting storage services.
