Concept: Email Delivery

This topic provides details on how to ensure workers receive emails from Workday Peakon Employee Voice.

Peakon sends emails using Amazon Web Services (AWS), specifically Simple Email Service (AWS SES).

Peakon emails have appropriate SPF and DKIM records. We use DMARC to track delivery and deliver emails over TLS if your email server supports it.

We send emails from these IP addresses:

Hosting Option	IP Addresses
EU	54.240.54.100 54.240.54.101 54.240.54.102 54.240.54.103
US	54.240.115.242 54.240.115.243 54.240.115.244 54.240.115.245
UK	76.223.133.166 76.223.133.167 76.223.133.168 76.223.133.169

These IP addresses should remain the same. Peakon could add additional IP addresses in the future.

All Workday Peakon emails come from the no-reply email address app@peakon.com.

We track email bounces using the <example>@bounce.peakon.com Return Path for EU-hosted tenants, <example>@bounce-us1.peakon.com Return Path for US-hosted tenants and <example>@bounce-eu2.peakon.com Return path for UK-hosted tenants, enabling us to provide alerts about email bounces so you can correct invalid emails.

Hosting Region	Emails
EU	*@bounce.peakon.com app@peakon.com
US	*@bounce-us1.peakon.com app@peakon.com
UK	*@bounce-eu2.peakon.com app@peakon.com

For Office 365 Advanced Threat Protection, set up mail flow rules to enable Office 365 to bypass safe links when scanning emails from Peakon:

Set the message header to: X-MS-Exchange-Organization-SkipSafeLinksProcessing and set the value to 1.

When emails soft-bounce, Peakon continues attempting to send emails, increasing the delay between each attempt. Emails can soft-bounce because of internet connectivity issues, target email server issues, or other temporary problems, so you don't need to take any action.

When emails hard-bounce or permanent bounce, Peakon stops sending emails to that address, and flags it as a bounced email address. Typos in email addresses, former employee email addresses, or incorrect spam rejections can cause hard bounces. If the email address is valid, you can clear the flag from the employee list.

We recommend that you test email delivery by sending test emails to a small group of employees. This enables you to troubleshoot if you encounter any issues.

Peakon enables you to select a sender for survey emails. We recommend that you review your email filters to ensure that they don't interfere with survey emails from specific addresses. Example: An organization configures their email server filters to identify mass emails from a single address as a spam incident. The filters block the organization's survey emails from the CEO.

Consider reviewing other email settings that could interfere with email delivery.

Peakon enables you to add certificates to emails. See: Reference: Company Account Settings.
