Paid subscription required to send emails.
The number of emails you can send is dependent on your subscription status:
If you have a trial QuickBooks account, and a trial Method account, you will not be able to send emails.
If you have a QuickBooks account, but a trial Method account, you will be able to send 100 emails. After that, emails will be blocked.
If you have a paid subscription with Method (regardless of your QuickBooks account), you will be able to send up to 5000 emails (unless you have the paid tier).
