How to Implement Authentication Tokens in Email Marketing?
To implement authentication tokens, follow these steps:
Set up DKIM: Generate a pair of cryptographic keys (public and private). Add the public key to your DNS records and configure your email server to sign outgoing emails with the private key. Configure SPF: Create an SPF record in your DNS settings to specify which mail servers are allowed to send emails on behalf of your domain. Enable DMARC: Create a DMARC policy in your DNS settings to instruct receiving servers on how to handle emails that fail DKIM or SPF checks.
