BIMI across 9 providers: who actually renders your logo?

Brand Indicators for Message Identification — BIMI — is the only standard that lets your logo appear next to your sender name in the inbox. The marketing pitch is universal. The reality in 2026 is that fewer than half of major mailbox providers render it at all, and the gap matters when you weigh the cost of a VMC certificate.

BIMI prerequisites are non-trivial: DMARC enforcement atp=quarantine or stricter, a published SVG logo with the BIMI profile, and (at most major providers) a VMC or CMC certificate that costs around $1.5K/year. Before paying, check which mailboxes your audience actually uses — not every provider renders the result.

TL;DR

Render-supporting in 2026: Gmail, Yahoo Mail, AOL, Apple Mail (iOS 16+ / macOS 13+). Limited or in preview: Outlook (paid Microsoft Defender for Office 365), Fastmail, La Poste. No support: GMX, T-Online, Mail.ru, Yandex, iCloud's older clients, most enterprise webmail.

Providers that render BIMI today

  • Gmail: renders BIMI with VMC required. Avatar shows in the inbox list and message header. Both Gmail mobile and web display it.
  • Yahoo Mail: renders BIMI; VMC optional but recommended. Logo shows in inbox and message header.
  • AOL: shares Yahoo's implementation — same support, same defaults.
  • Apple Mail (iOS 16+ / macOS 13+): renders BIMI with VMC. Notably this is client-side — the logo only shows in Apple's native Mail app, not in third-party clients reading the same iCloud account.

Providers in preview / limited support

  • Outlook / Microsoft 365: BIMI is gated behind Microsoft Defender for Office 365 plans. Consumer Outlook.com does not render BIMI in 2026.
  • Fastmail: renders BIMI with DMARC-only, VMC not required. Niche but technically forward.

Providers that do not render BIMI

  • GMX, web.de, mail.com, T-Online: no BIMI support announced. United Internet has not published a roadmap.
  • Mail.ru, Yandex Pochta: no BIMI support and no public roadmap. Both providers do their own sender-branding via verified-sender programs that are not BIMI-compatible.
  • iCloud (third-party clients): if the user reads iCloud mail in something other than Apple Mail (e.g. Outlook for Mac, Spark, Mimestream), BIMI is not rendered.
  • Most enterprise webmail (Zimbra, Roundcube, OpenXchange) does not render BIMI by default.

BIMI prerequisites — the real cost

  • DMARC p=quarantine orp=reject on the From-domain. SPF and DKIM must align in production traffic.
  • SVG Tiny PS profile for the logo, hosted at a stable HTTPS URL. Use the BIMI Inspector to verify before publishing.
  • BIMI DNS record atdefault._bimi.example.com pointing at the SVG (and, when used, the VMC).
  • VMC or CMC certificate from a participating CA (Entrust, DigiCert). Annual fee around $1.5K. Required at Gmail and Apple Mail; optional at Yahoo/AOL but increasingly recommended.

Is BIMI worth it for you?

Map your audience by mailbox provider before paying for a VMC. If your contacts are mostly on Gmail and Apple Mail, the answer is usually yes — the inbox-list logo is a measurable open-rate lift on first impression. If your audience is DACH-heavy (GMX, T-Online), CIS-heavy (Mail.ru, Yandex), or enterprise Outlook-only, the visible benefit is small enough that the VMC cost is hard to justify. Run the inbox-placement test against your audience first; the email-stats reports page on this site has a daily snapshot of which mailbox provider is most common across the Tranco top-1M.

Either way, getting your domain BIMI-eligible (DMARC enforcement, aligned DKIM, published SVG) is most of the work — and that work has standalone deliverability benefits across every provider, BIMI or not. Test before and after with our free inbox placement test to confirm the DMARC tightening did not accidentally break a sub-domain.

Will Mail.ru or Yandex add BIMI?

No public roadmap as of 2026. Both providers run their own verified-sender programs that are not BIMI-compatible. Plan for years, not quarters, before betting on parity.

Can I use BIMI without a VMC?

Only at Yahoo, AOL and Fastmail. Gmail and Apple Mail require a VMC certificate. Without one your logo will not render at the largest BIMI-supporting providers.

Does BIMI affect inbox placement?

Indirectly. BIMI itself is not a placement signal, but its prerequisite (DMARC enforcement with passing alignment) is. Senders who go through the BIMI work usually see placement improvements from the underlying DMARC tightening, not from BIMI itself.
