Setting up BIMI at webgo — Step-by-Step Guide (2026)

Last updated: July 2026

In short: BIMI displays your verified corporate vector logo right next to your emails inside recipient inboxes. You enable this visual seal by publishing the public URL of your logo as a TXT record on the default._bimi subdomain inside your webgo DNS settings.

Prerequisites

A webgo web hosting or email plan with an attached domain
Access to the webgo customer portal (https://login.webgo.de) or Webspace-Admin
An active, strict DMARC policy (p=quarantine or p=reject) configured on your domain (DMARC at webgo)
A brand logo exported specifically in the SVG Tiny PS format, publicly accessible over HTTPS

What is BIMI?

BIMI (Brand Indicators for Message Identification) attaches visual brand verification to strong email security practices. Supporting mail providers (such as Gmail, Apple Mail, and Yahoo) check whether incoming messages originate from a domain publishing a valid BIMI record — and display the verified logo next to the subject line in the inbox.

Beyond branding, BIMI provides visual protection against spoofing. Mail clients only display the logo if two strict authentication requirements are satisfied:

Your domain passes strict SPF alignment and carries valid DKIM signatures.
Your domain enforces a strict DMARC policy (p=quarantine or p=reject). If DMARC remains in monitoring mode (p=none), the logo is ignored.

As webgo notes regarding resource records in DNS: Der TXT-Eintrag erlaubt das Speichern von beliebigen Textinformationen. Häufig wird er verwendet, um Domains bei Diensten zu verifizieren oder das E-Mail-Verhalten zu verbessern (SPF, DKIM, DMARC).

The starting point at webgo

You configure BIMI records inside your domain’s DNS management table in the webgo customer portal or Webspace-Admin (Der TXT-Eintrag erlaubt das Speichern von beliebigen Textinformationen. Häufig wird er verwendet, um Domains bei Diensten zu verifizieren oder das E-Mail-Verhalten zu verbessern (SPF, DKIM, DMARC).).

The entry is published as a TXT record attached to the reserved subdomain default._bimi. The canonical structure of the entry is:

v=BIMI1; l=https://example.com/logo.svg

Step-by-step guide

1. Verify your DMARC enforcement level

Before publishing your BIMI record, check via terminal or MXAudit that your DMARC policy is set to p=quarantine or p=reject. If your DMARC record reads p=none, email clients will refuse to render your logo.

2. Host your logo in SVG Tiny PS format

Your logo file must adhere strictly to the SVG Tiny PS profile (square aspect ratio, pure vector paths, no external links, scripts, or bitmap references). Upload this file to your webgo web hosting space so that it is publicly reachable via a secure HTTPS URL (for example, https://example.com/logo.svg).

3. Open DNS management at webgo

Log in to the webgo customer portal (login.webgo.de), select your package, and open DNS-Verwaltung (DNS management inside your customer dashboard or in Webspace-Admin under Domain / DNS).

4. Add the TXT record for default._bimi

Inside your DNS management table, add a new entry with the following parameters:

Type: TXT
Subdomain / Host: default._bimi
Text value / Content:
```
v=BIMI1; l=https://example.com/logo.svg
```

(Replace https://example.com/logo.svg with the actual public HTTPS link where your vector logo file is stored).

Save your new DNS entry.

The components of the BIMI record

Component	Meaning
`default._bimi`	The default selector (`default`) inside the BIMI technical namespace in your domain’s DNS
`v=BIMI1`	Protocol version tag (must strictly appear at the very beginning of the TXT string)
`l=https://...`	Absolute HTTPS URL pointing to the publicly hosted SVG Tiny PS vector file

Verification

Once you save your record inside webgo’s DNS settings, immediately test your setup using the free MXAudit scanner — check your BIMI syntax and verify that your logo file passes SVG validation.

You can also use your terminal to confirm that nameservers are serving your new record:

dig TXT default._bimi.example.com +short

The output should match "v=BIMI1; l=https://example.com/logo.svg".

Common mistakes

Leaving DMARC in p=none: This is the most common reason why logos fail to appear in Gmail or Apple Mail. BIMI strictly requires DMARC enforcement (p=quarantine or p=reject).
Uploading incompatible image formats: Standard PNG, JPG, or unoptimized SVG files are rejected silently by receiving mail clients (Der TXT-Eintrag erlaubt das Speichern von beliebigen Textinformationen. Häufig wird er verwendet, um Domains bei Diensten zu verifizieren oder das E-Mail-Verhalten zu verbessern (SPF, DKIM, DMARC).). Your graphic must be exported Specifically using the SVG Tiny PS profile.
Placing the record on root (@): If you create the TXT record on your root domain instead of the default._bimi subdomain, external mail servers will not discover your visual branding.
