SPF, DKIM, and DMARC are three widely recognized email authentication protocols. When properly implemented, they authenticate your email provider to send emails on your behalf and ensure your messages' integrity throughout the delivery process.
At the same time, improper implementation of these protocols can prevent your email from reaching the recipient's inbox. That's why it's important to understand the basics of each protocol, correctly configure the DNS records that come with each protocol, and update them whenever you change how emails are sent on behalf of your domain.
👉 SPF, DKIM, and DMARC are implemented by adding appropriate DNS records to your domain's configuration.
For simple cold email setups, such as when using a dedicated cold email domain to send emails via Hunter Campaigns, the best way to find appropriate DNS records is to follow your email provider's instructions.
