There is a daily limit of 1000 single and 1000 mass emails in sandbox. You can check it yourself by going to workbench and logging with your sandbox credentials, Then do a GET request fot the limits like this:

  • You can send mass email to a maximum of 1,000 external email addresses per day per org based on Greenwich Mean Time (GMT).

    • Even if it is 1000(Unlimited Edition), it is lower for Professional(250), Enterprise(500) orgs .
