<b>What's that DKIM thing my email tool keeps nagging about?</b>

DKIM is basically a tamper-proof signature that tells inboxes your email really came from you and wasn't changed on the way. It's added invisibly to every message you send.

Why it matters: emails without DKIM look unverified, and Gmail now flat-out requires it for bulk senders. No DKIM often means straight to spam.

✅ Do this:
— In your email tool, find the "authenticate domain" or DKIM section
— Copy the record they give you into your domain's DNS settings
— Wait, then confirm it shows green in the dashboard

If SPF is the guest list, DKIM is the wax seal on the envelope proving nobody opened it.

Homework: open your email tool and check if DKIM shows as verified.
