What are SPF, DKIM, and DMARC and do I really need them?

These three are email's ID checks that prove you're really you. Skipping them is the top reason beginners land in spam. Here's each in plain English.

SPF is a list of servers allowed to send for your domain. DKIM is a tamper-proof signature on each email. DMARC is the rulebook telling inboxes what to do if SPF or DKIM fail.

— Step 1: In your email tool, open the "authentication" or "verify your domain" section.
— Step 2: ✅ Follow its steps to add the SPF and DKIM records to your domain. The tool gives you exact text to paste.
— Step 3: Add a simple DMARC record once both pass.

Why it matters: without these, Gmail and Yahoo now treat bulk senders as untrusted by default.

Homework: log into your email tool and check if your domain shows "verified."
