Check BIMI.
BIMI shows your logo next to the sender in Gmail and Yahoo. It requires strict DMARC, an SVG Tiny PS logo and, for Gmail, a VMC certificate. I check each condition.
What to fix, in this order
Nothing to fix in this check.
Before you ask.
Why does the logo not show in Gmail?
Gmail requires three things at once: DMARC with p=quarantine or reject and pct=100, an SVG Tiny PS logo at an HTTPS address and a valid VMC or CMC certificate. Yahoo shows the logo without a certificate.
What is SVG Tiny PS?
A restricted SVG profile: square logo, no scripts, no external references, with baseProfile="tiny-ps" and a title element. A plain export from a design tool usually does not meet it.
Does BIMI make sense for a small store?
Rarely. A VMC certificate costs a few hundred dollars a year and requires a registered trademark. Finish SPF, DKIM and DMARC first, they decide deliverability.
Would you rather have meset it up and watch it?
WooCommerce store support plans from 1,200 PLN net per month, no minimum term. For a 20-minute call I keep two fixed slots: Tuesday and Thursday, 18:00-19:00 CET.
