How SMS and Email Sending Limits Work

Source: autosoft-workshop/app/controllers/inspections_controller.rb, workshop_mailer.rb

Daily sending limits by subscription: Trial=9, Limited Active=249, Active=3000
Email uses different AWS accounts based on server region (AU vs other)
No queue or retry — if sending fails, it fails silently
Inspection approval emails set status to "requested_approval" — hangs indefinitely if customer doesn't respond

"Emails stopped sending" → daily limit hit, no warning shown
"Customer never got the inspection approval" → email failed silently or hit spam filter
