Keep in mind!
For an email, the individual attachment file that is supported is up to 10 MB.
The total email size limit should not exceed 25 MB.
Note that file types supported by the NetSuite API are different than those supported natively in their UI. This means that certain file types can be added in the UI but cannot be added via apps like ExtendSync that need to communicate via the API.
