[SalesForce] Salesforce Email are not received by recipient

We had a similar issue pertaining to email. What we found was that emails generated from Workflow were not reaching email addresses (specifically on the Gmail domain). Using the Email Log Files we determined that the sending user for emails sent by the Automated Process user was "rsandoval@ourorgid" with no ".com" appended. This meant that Gmail would ignore it and the email wasn't being delivered.

For this scenario the answer was to update the Email Alert's setting for "From Email Address" to use "Default Workflow User's email address" instead of "Current User's Email Address".

What is particularly interesting is that in each Org that uses the Automated Process user, the associated email is "Rsandoval@ourorgId". I'm guessing that "RSandoval" was the engineer that created the Automated Process global user when it was first created? Weird.

if no email is going out of the org, then You should check for the Deliverability of the Org.

No access: Prevents all outbound email to and from users. System email only: Allows only automatically generated emails, such as new user and password reset emails. Especially useful for controlling email sent from sandboxes so that testing and development work doesn’t send test emails to your users. Newly created sandboxes default to System email only. All email: Allows all types of outbound email. Default for new, non-sandbox organizations. Sandboxes created before Spring ’13 default to All email.
