Secure Email Relay
When it comes to deliverability, it’s important to separate your user-based email from application email, while still achieving the same levels of protection.

Proofpoint’s Secure Email Relay service is an advanced solution for your transactional email being sent from applications or sent on your behalf by third-party partners. It supports migration from your on-prem relays to the cloud, provides standardization and centralized control for applications that send email, and protects your trusted domains from being abused by vulnerable apps or compromised email service providers. And Secure Email Relay can also accelerate your DMARC implementation by DKIM signing your transactional messages before being sent.

Secure your application email and accelerate DMARC implementation

Send secure application email
Protect your email recipients by only allowing approved sources to connect to your relay. And scan messages for malicious content and apply DKIM signing before sending.

- Provides a single, centralized, solution to secure email being sent from internal applications, multifunction printers and third-party partners
- Reduces the attack surface surrounding identity takeover by scanning application email with anti-spam and anti-virus tools
- Simplifies the authentication of application senders by DKIM-signing email that uses your domain to achieve DMARC compliance
- Protects against data leaks and secures sensitive data, such as personally identifiable information (PII) and personal health information (PHI), by applying optional payload encryption and/or data loss prevention (DLP) to application email

Better manage your third-party senders
When third-party senders are sending application email on your behalf, it puts your trusted domains at risk. But you can regain control through consolidation and centralized management.

- Secure application email from SaaS providers, such as ServiceNow, Salesforce, and Workday, that send on your behalf
- Gain visibility into application email by validating third-party senders who are sending emails using your domains
- Provide DKIM-signing to senders who use your domain to achieve DMARC compliance
- Have the power to shut off sending from any compromised third-party sender
