I have created a site to create case. I have a time dependent workflow in case object which will send email alert after one hour if the case is still at queue.
The Workflow action is triggered successfully and i can see it in Monitoring. but the user does not receive any email.
I have checked the email deliverable and i got 52 emails from salesforce. I have added the same email alert in immediate workflow action and i got email. This email alert has VF email template.
Can you help me on this? what could be the possibility of not getting email from sandbox?
Edit: I am using additional email address field only. I have tried with various email addresses.
