Concept: Email Deliverability

Workday incorporates features that reduce the number of emails sent to invalid email addresses. You can use reports to view unsent emails and to identify invalid email addresses so that you can correct them. These tools help to improve the rate of successful email delivery to email recipients.

Workday Email Block List

Workday uses an email block list to validate recipient email addresses for all emails sent from your Workday tenant, whether you use a Workday or custom SMTP. Workday doesn’t deliver emails sent to email addresses that match specific criteria on the block list, such as invalid domains. Workday classifies a domain as invalid if it contains a typo or lacks a mail exchange (MX) record.
When you set up an email redirect restriction on the
Edit Tenant Setup - Notifications
task, and the email address of the original recipient is invalid, Workday doesn't send an email to the redirect email address.
You can use these reports to view the undelivered email notifications:
Report
Description
Emails Not Sent Due to Blocked List
View the most recent email notifications with email addresses that matched criteria on the blocked list. You can filter the results of the report by date range. You can also determine whether an undelivered email address belongs to a specific contact or a static email address.
Business Process and Integration Notifications Indexed
View all email notifications sent from your Workday tenant. Use the
Emails Not Sent Due to Blocked List
column to determine whether Workday delivered the email notification or blocked it.
Using these reports, you can identify email addresses in your tenant that you need to update to ensure successful email delivery.
