The email you received tells you what to do:

"If you expected this email, please contact [put sender here] to correct the problem."

SPF is part of DTC's security to protect its email and you.

Here is why:

- Sender Policy Framework (SPF) is used to authenticate the sender of an email. With an SPF record in place, Internet Service Providers can verify that a mail server is authorized to send email for a specific domain. An SPF record is a DNS TXT record containing a list of the IP addresses that are allowed to send email on behalf of your domain.

Why is SPF Important?

- SPF has become exceedingly vital to help verify which sending infrastructure can relay email on behalf of your domain.

SPF for email provides major benefits:

- Increases domain reputation and email deliverability.
- Fights domain impersonation and email spoofing to protect your brand reputation.
- One of the foundational methods of email authentication for DMARC.
