I have a premium account and we have integrated your API with our software we need to increase the 20MB limit to 50MB limit on fax as we have to send bulk faxes on a daily basis.

I came here from Discord. Without a paid plan, it's 8 mb. You can't even share videos longer than a minute due to the file limit. Lol, maybe use a file sharing service and send your faxes through links? @sandy-durst
