yeah that should be more than enough thanks. I checked the data and file storage limits (sfdx force:limits:api:display) and it's 200MB and 50MB so that is tons as well.

What about single email limits? We had created a small email app before and I had to get that limit increased. If I was to do any further work on that feature I'd need that number to increase. 15 emails goes very quickly. I guess I could fire up a 2nd or 3rd scratch org...
