Invoices are queued to be emailed - why are they not being sent?

The email service runs on a scheduled task and is programmed to send emails every few minutes. If after an unexpected amount of time the emails are still not sent, there could be a problem with the SMTP settings, the email service or similar. Your first point of contact here would be your technical department.

Refer to docs.varibill.com for more information on emailing invoices and the email activity log.
