I normally have a flood of payments by now but there are none - how can I check they were all sent. I am worried that your 10 day flushing rule is approaching…
Are you referring to automatic reminders or recurring invoices? What emails are you expecting to be sent?
How do you send your emails - SMTP or QuickFile servers?
Whatever the email, they usually appear in the Events Log - either at the bottom of your dashboard, or you can go into Account Settings and select Event Log Browser.
As @Parker1090 mentions the event browser would be the best place to look in either case. You will find this in the account settings area.
