Unimarket uses Postmark to manage email delivery, ensuring high security, reliable delivery rates, and professional bounce handling. To verify that emails sent by the system are authorized by your organization, Unimarket utilizes DKIM (DomainKeys Identified Mail) and offers a Custom Return Path configuration.
Email Authentication via DKIM
DKIM is the industry standard for email authentication. It uses a digital signature to prove to the recipient's mail server, that the email was indeed sent. By an authorized sender and has not been altered in transit. This setup ensures that when a supplier receives a PO notification, it appears to come directly from your domain (e.g., procurement@customerdomain.com).
Understanding "Mail From" vs. "From"
By default, email clients may display Unimarket emails in two different ways depending on your technical setup:
Standard Setup (Default): Unimarket sets the "MAIL FROM" header to
bounce@customer.unimarket.com. This ensures that if an email bounces, Unimarket can track it.- User Experience: The recipient may see
example@customerdomain.com via unimarket.com.
- User Experience: The recipient may see
Custom Return Path (Recommended): This authorizes Unimarket to send emails entirely on your behalf.
User Experience: The recipient sees only
example@customerdomain.com. The "via Unimarket" label is removed.
Return Path Setup (White Labeling)
Configuring a custom Return Path aligns your "MAIL FROM" address with your "FROM" address. This is the best way to prevent your emails from being flagged as spam by aggressive filters.
1. DNS Configuration (CNAME)
You must create a CNAME entry in your DNS settings. That points your custom bounce domain to Unimarket.
Target Domain:
bounce.customerdomain.comPoints to:
unimarket.com
2. Domain Alignment
The Return Path must share the same suffix as your primary email domain.
If your email is:
user@customerdomain.comYour Return Path should be:
bounce@pm.customerdomain.comorbounce@bounce.customerdomain.com.
Implementation Steps for Administrators
Coordinate with IT: Provide your IT or Network team with the CNAME requirements mentioned above.
Access Settings: Once the DNS record is live, go to Administration > Settings > Profile.
Enter Return Path: Locate the Email Delivery Authentication section and enter your Return Path address.
Validate: Click the Validate Return Path button. The system will check your DNS to ensure the CNAME is correctly mapped.
Benefits of Custom Return Path
Professional Branding: Removes the "via unimarket.com" tag from the sender field.
Improved Deliverability: Higher "sender reputation" since the email headers are fully aligned with your brand.
DMARC Compliance: Helps your organization meet strict DMARC policies by ensuring the Return Path domain matches the From domain.
