My playground will not send new users an email with their password reset links when the users are generated. The users are also not sent an email when selecting the option to reset their passwords. Users will not receive emails from flow Action "Send email". Users will receive an email when testing deliverability and using the Action "Email" from Actions and Recommendations.
Background:
I have been developing a flow that processes Account, Contact, and User information. In that process I create records for three custom objects. All records are created correctly and processed appropriately. At the very end of the flow I have a "Send Email" Action. The action does not send an email. I have checked my spam, Promotions, and Social inboxes.
When testing the deliverability through Setup I receive an email but I am simultaneously met with an error message "Failed to send email". I receive the "Do not reply" email from noreply@Salesforce.com.
When testing the "Email" Quick Action under Actions and Recommendations I am able to successfully send and receive the email. I receive the email from the Organization Wide Email Address (which is my email).
When examining the last set of email logs I noticed that the sender for the password generation "info@salesforcedevs.com" and for the Flow Application was from "info@salesforce.com", "noreply@salesforce.com" or the OrgWideEmailAddress that was set to my email address. The sender "info@salesforcedevs.com" resulted in a Delivery Status Notification that states the email was blocked due to the sender being unauthenticated. Is there any way to configure all of these senders? Is there a way to understand the inconsistency?
I have combed Salesforce help documentation, googled the issue in general, and even had an unhelpful call with Salesforce Technical Support. As this flow is in a playground they refused to help and directed me here. The research lead me to configuring Deliverability Settings to include "All Email" , setting my Organization Wide Email Address to be my own email address, turned off "Enable compliance with standard email security mechanism", sand combing through Requested Email Logs.
I am desperately trying to get the flow action "Send email" to work. Any and all help would be greatly appreciated.
@Max Chervinsky There are several considerations here... Regardless, See my community post, "How-To: Prevent Your Emails from Being Marked As Spam and Achieve High Email Deliverability Rates" for guidance.
