80MB is not even close to what you can send with most mail providers.
I see two likely paths forward:
1. Figure out what you would need to do in general to compress the file sufficiently, and then we can see how this would translate into NiFi
2. If the above is simply not feasible, consider writing the file to a file storage (e.g. S3 or HDFS) and only mailing the link or path. Do give some thought to security of course.
Sidenote: In general, the recommendation for urgent functional questions is to contact your account team directly.
