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).
