Question 1

Why is my logo not showing in Gmail?

Accepted Answer

Gmail shows your brand logo only when mailbox conditions are met: enforced DMARC (anti-spoofing), a valid SVG Tiny PS logo, and usually a VMC. Without those, the logo will not appear - even if a BIMI DNS record exists. This checker shows which condition still blocks display.

Question 2

Does Microsoft 365 support BIMI?

Accepted Answer

Not in the standard Outlook / Microsoft 365 inbox experience. BIMI is mainly useful for Gmail, Yahoo, Apple, Fastmail, Onet Poczta, and similar participating providers.

Question 3

What is SVG Tiny PS?

Accepted Answer

A restricted SVG profile for BIMI logos: tiny-ps baseProfile, viewBox, no scripts or external references. Most logo export tools need manual cleanup.

Question 4

Do I need pct=100 with p=reject?

Accepted Answer

This checker requires pct=100 (or omitted pct) for both quarantine and reject so coverage is complete. Partial pct is flagged as an error.

Question 5

Where will I see the BIMI logo?

Accepted Answer

In supporting mailbox UIs on received, DMARC-aligned mail - most visibly Gmail (logo; blue checkmark typically needs a VMC), Yahoo Mail, Apple Mail / iCloud, Fastmail, and Onet Poczta. You will not see BIMI logos in standard Microsoft 365 / Outlook. The logo appears next to the sender in the inbox or message view, not as a website badge or in every provider screen.

Question 6

Which companies in Poland use BIMI?

Accepted Answer

Examples include allegro.pl, mbank.pl, and mediaexpert.pl - they publish BIMI in public DNS (logo URL plus certificate). The list changes; this checker confirms the live record for any domain.

Question 7

Does Onet Poczta support BIMI?

Accepted Answer

Yes - as a Polish mailbox provider, Onet Poczta can display BIMI logos for senders.

Question 8

Does Yahoo require high sending volume for BIMI?

Accepted Answer

Yahoo does not publish a fixed message-count threshold, but official Sender Hub guidance says logos appear for bulk mail to a large number of recipients - not personal one-to-one mail - and only when reputation and engagement look sufficient.

Question 9

Which companies use BIMI globally?

Accepted Answer

Among others, public DNS currently publishes BIMI for paypal.com, apple.com, amazon.com, linkedin.com, visa.com, mastercard.com, cloudflare.com, booking.com, adobe.com, and americanexpress.com - and many other well-known brands that invest in email security and standing out to customers in the inbox.
