How Does Domain Validation Work?
Domain validation typically involves verifying DNS records like SPF, DKIM, and DMARC. These records help in authenticating the email sender’s domain and ensuring that it is not being spoofed by malicious actors.
SPF: Specifies which mail servers are permitted to send emails on behalf of your domain.
DKIM: Adds a digital signature to your emails, allowing the recipient’s server to verify that the email hasn’t been tampered with.
DMARC: Provides instructions to email servers on how to handle emails that fail SPF or DKIM checks.
