If an email is sent it will also show in the Timeline when you are in the Dashboard on the Web Portal. This reflects any action/s taken over a time period.
If an email communication has been sent out in relation to a job this will show under Communications in the job. Go to Jobs > View Jobs > Edit Arrow for the selected job > Communications. > Email / SMS. There will be a list of emails that were queued, and whether they were sent successfully or failed to send.
You are also able to view whether a submitted form has been emailed in the Submitted Form Email Log. To do this in your Web Portal, go to Forms > Submitted Forms > Select the Edit Arrow for the submitted form you want to see the email log for > Email Log.
The Forms email log is also visible in your Web Portal, by going to Settings cog > Email & SMS > Forms Email Log.
Or by going to Tools > View Email Log > Forms Email Log.
If you want to view CRM emails (email reminders sent for jobs, or invoice / quote emails), select the CRM Email Log tab.
