[Frequently Asked Questions](https://help.lendingwise.com/knowledge/frequently-asked-questions?hsLang=en) # SPF, DKIM and DMARC (2024 Changes) ## (DKIM Changes set by Email/Domain Providers) ### What is DMARC? - **Purpose**: DMARC (Domain-based Message Authentication, Reporting, and Conformance) is an email authentication protocol that allows domain owners to protect their domain from unauthorized use, commonly known as spoofing. - **How it Works**: DMARC builds on two existing email authentication mechanisms — SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) — to verify the identity of the email sender and specify how receiving mail servers should handle messages that fail authentication. ### Why Should You Set Up DMARC? - **Enhanced Security**: Protect your domain from phishing scams, spoofing, and business email compromise (BEC). - **Improved Deliverability**: Emails are more likely to end up in the recipient's inbox, not the spam folder. - **Visibility**: Receive aggregate and forensic reports showing which sources are sending email on behalf of your domain, making it easier to identify unauthorized senders. ### Steps to Set Up DMARC 1. **Confirm SPF and DKIM Are in Place**: Before setting up DMARC, confirm that SPF and DKIM are correctly configured and passing authentication for your domain. DMARC requires at least one of these to be in alignment to function. 2. **Create a DMARC Record**: Create a DMARC TXT record in your DNS settings. - Example: `v=DMARC1; p=none; rua=mailto:reports@yourdomain.com` 3. **Testing Mode**: It is recommended to start in monitoring mode (`p=none`) to collect data without affecting email delivery. Review reports for at least 2–4 weeks before moving to a stricter policy. 4. **Analyze Reports**: You will receive XML-formatted aggregate reports (RUA) via email, detailing authentication results for emails sent from your domain. Consider using a DMARC report analyzer tool to interpret these reports more easily. 5. **Policy Implementation**: After monitoring, switch to a stricter policy like `p=quarantine` or `p=reject`. ### Things to Consider - **Third-Party Sender Impact**: Implementing DMARC may affect third-party services that send email on your behalf (e.g., CRMs, marketing platforms, or transactional email providers). Ensure these services support SPF/DKIM alignment or are added to your SPF record before enforcing a strict DMARC policy. LendingWise supports SPF configuration through our SendGrid integration. DMARC configuration must be managed directly through your domain or DNS provider. If you have questions about SPF setup within LendingWise, our support team is happy to help.   LendingWise does not set up DMARC records on your behalf and is unable to provide direct assistance with DNS configuration. Please contact your domain registrar or DNS/hosting provider for help.  - [Overview of LendingWise Platform](https://help.lendingwise.com/knowledge/overview-of-lendingwise-platform?hsLang=en#main-content) -
