1. Set Up Authentication Protocols

To make sure email providers trust that you’re the real sender, you’ll need to set up a few "signatures" that verify your emails. You can set these up with your domain provider (like GoDaddy or Namecheap) and your email service provider (like Gmail, Yahoo, or a marketing tool).

Step 1: Set Up SPF (Sender Policy Framework)

  • Go to the place where you manage your domain (e.g., your GoDaddy or Cloudflare account).

  • Look for where you can add something called a “TXT record.”

  • Create a new entry (or “record”) that says only approved sources (like your email provider) can send emails from your domain.

Step 2: Set Up DKIM (DomainKeys Identified Mail)

  • Go to your email provider's settings, usually under "Security" or "Email Authentication."

  • Follow their instructions to create a “DKIM key.” This key is like a digital stamp that says, “This email is definitely from us.”

  • Add this key in your domain settings as a new “TXT record” so your emails show they’re legitimate.

Step 3: Set Up DMARC (Domain-based Message Authentication)

  • In your domain settings, create another “TXT record” that defines how Google, Yahoo, and others should handle emails that don’t pass the above checks.

  • You’ll also set up where reports should be sent if there are issues (like to a specific email of yours).
