Hi DelpClem,
Looks like you're having trouble with email delivery for your invoices. I see how important it is to make sure all invoices are sent and received correctly. I checked your account and saw you're using AccountRight, so I moved your post to the AccountRight board.
If you're sending emails from the desktop version of AccountRight, you might want to check this post for info on email history. If you're using the browser version, check out this thread for details on email activity.
Feel free to get in touch if there's anything else I can assist you with.
Cheers,
Princess
