In short: BIMI shows your brand logo next to your emails. After this guide you publish the
default._bimiTXT record in the Hetzner Console — and know the prerequisites: DMARC, SVG logo, certificate.
Prerequisites
- A DNS zone at Hetzner
- DMARC at enforcement (
p=quarantineorp=reject) - Logo as SVG Tiny PS and (for Gmail & co.) a VMC
- An HTTPS server for the logo and certificate
What is BIMI?
BIMI (Brand Indicators for Message Identification) is a TXT record that points to your brand logo. Gmail, Apple Mail, and Yahoo show it next to your authenticated emails. BIMI is not a security method of its own, but the visible reward for clean SPF, DKIM, and DMARC — the last step.
The real work isn’t in the record
As a DNS service, Hetzner is the ideal place to publish the BIMI record — but the prerequisites lie with your mail infrastructure. The BIMI Group names them clearly:
- DMARC at enforcement. Your policy must “be at enforcement on the organizational domain and subdomains” — a
p=noneor apctunder 100 “policies or ‘pct’ less than 100 percent are not accepted”. See DMARC for Hetzner. - SVG logo. “Produce an SVG Tiny PS version of your official logo” — square, over HTTPS.
- VMC or CMC. In practice needed for display at Gmail & co. (“highly recommended, but Optional”). Self-asserted BIMI “records have limited support across the various Mailbox Providers”.
Step-by-step guide
1. Check the prerequisites
With the free MXAudit scanner you check SPF, DKIM, and DMARC — DMARC must be at quarantine/reject.
2. Provide the logo and (optionally) certificate
Place the logo as SVG Tiny PS over HTTPS, obtain a VMC/CMC, and serve the .pem file over HTTPS.
3. Create the BIMI TXT record in the Hetzner Console
As with the SPF and DKIM record:
| Field | Value |
|---|---|
| Type | TXT |
| Name | default._bimi |
| Value | "v=BIMI1; l=https://example.com/logo.svg; a=https://example.com/vmc.pem" |
As with all TXT records in the Hetzner Console: the value must be in quotation marks. Basic scheme per the BIMI Group: default._bimi.[domain] IN TXT "v=BIMI1; l=[SVG URL]; a=[PEM URL]". Without a certificate you leave out a= — it’s “currently optional”. A real record (ebay.com):
v=BIMI1;l=https://vmc.digicert.com/….svg;a=https://vmc.digicert.com/….pem
4. Wait and check
After DNS propagation, check the record with the MXAudit scanner or the BIMI Inspector of the BIMI Group.
Common mistakes
Forgot the quotation marks. In the Hetzner Console the TXT value goes in quotation marks.
BIMI without DMARC enforcement. p=none isn’t enough; quarantine/reject is mandatory.
Wrong SVG format. Only SVG Tiny PS, square.
No VMC, expecting Gmail display. Without a certificate the logo usually stays invisible at the large providers.
