How to secure your custom website, and domain email services for free using Cloudflare

You want a custom domain for your website and email, but you don’t want to pay someone to manage your email security?

Email security is important to protect your organization from phishing attacks and email fraud. There are several email security features that you can enable for your custom domain, including DNSSEC, SPF, DKIM, and DMARC. DNSSEC is a security protocol that authenticates DNS data and can help prevent DNS spoofing attacks. SPF is a security protocol that helps to prevent email spoofing by verifying that email messages come from authorized senders. DKIM is a security protocol that uses digital signatures to verify the authenticity of email messages. DMARC is a security protocol that helps to prevent email spoofing by verifying the alignment of SPF and DKIM policies. Enabling these email security features for your custom domain can help to protect you from email fraud and phishing attacks. As well as make sure that your legitimate email is not marked as spam.
