BIMI puts your logo next to your emails in supported inboxes. That is the whole of it, and the reason it gets more attention than it deserves is that it looks like a deliverability feature.

It is not. BIMI is a reward for getting your authentication right, not a fix for getting it wrong. The logo only appears once SPF, DKIM and DMARC are already in order, which means every business that successfully implements it had already done the valuable part before the logo showed up.

Worth doing, for some businesses, for reasons that have nothing to do with placement. What follows is everything involved, including the parts most guides leave out.

 

## What this covers

1. What BIMI is, in one paragraph.
2. Where your logo appears, where it does not, and the Apple scheme that is not BIMI at all.
3. VMC, CMC and self-asserted, and what each one buys you.
4. Whether it helps deliverability, which is the question everybody everybody really asks.
5. The process, the failure points, and the real cost in pounds.
6. And a decision guide, because for plenty of businesses the answer is no.

 

 

 

# The basics

## What BIMI is

Brand Indicators for Message Identification is a standard that lets a mailbox provider display your logo beside your messages. You publish a DNS record pointing at a hosted logo file and, in most cases, a certificate proving the logo is yours. The provider fetches both, validates them, and shows the logo if everything checks out.

The entry requirement is the important bit. BIMI only works on domains with DMARC at enforcement, meaning a policy of quarantine or reject applied to all of your mail. A domain sitting at p=none does not qualify, and no certificate will change that.

 

# Where it shows

## Support varies more than most guides admit

- Gmail: yes, with a certificate. A VMC or a CMC will display your logo. The blue verified checkmark requires a VMC specifically. A CMC gets you the brand avatar and no tick.
- Yahoo and AOL: yes, and a certificate is not always required. Yahoo can display a self-asserted logo without a certificate, subject to passing their own reputation and bulk sender checks. The cheapest route to a visible logo anywhere.
- Apple Mail: yes, but VMC only. Apple requires a Verified Mark Certificate backed by a registered trademark, and will not accept a CMC. Supported since late 2022 across iOS 16, iPadOS 16, macOS Ventura and iCloud.
- Fastmail, Zoho, GMX, La Poste and others: supported in some form. Smaller audiences, and worth checking individually if one of them is a meaningful share of your list.
- Outlook and Microsoft 365: no. No receiving-side support and no published roadmap for it.

 

### And the thing most BIMI guides have not caught up with

Apple now runs its own branding scheme, separate from BIMI, called Apple Branded Mail. It works through Apple Business Connect, needs no VMC and no registered trademark, and shows a Mail Verified badge rather than the blue checkmark. You register the brand, verify domain ownership and submit the logo, and it applies to recipients on iOS 18.2 or later.

It only works in Apple Mail, so Gmail and Yahoo do not participate. For a business with an Apple-heavy consumer audience and no trademark, it changes the maths considerably, because the expensive route to Apple Mail is no longer the only route.

 

# The certificates

## VMC, CMC and self-asserted

 

### Verified Mark Certificate

- Requires a registered trademark. Which is the real gate. No trademark, no VMC, regardless of budget.
- Gets you the most. Logo in Gmail, the blue verified checkmark in Gmail, and Apple Mail support.
- And costs the most, in money and in time. Trademark registration takes months if you do not already have one.

 

### Common Mark Certificate

- No trademark required. Instead you need evidence of at least twelve months of continuous public use of the logo on your domain. Certificate authorities verify this, including through web archive records.
- Gets you the logo in Gmail. No blue checkmark, and no Apple Mail.
- Cheaper, and the sensible starting point for most. Particularly for businesses whose audience is Gmail-weighted.

 

### Self-asserted, with no certificate

- Free. You publish the DNS record and host the logo, with nothing proving ownership.
- Yahoo and Fastmail only. Gmail and Apple will not display it. Still worth doing if you are already at DMARC enforcement, because it costs nothing but an afternoon.

 

# The myth

## Does BIMI improve deliverability?

No, not directly, and anybody selling it to you on that basis is overselling.

- There is no measurable placement lift from the logo itself. Mailbox providers do not reward you for displaying a certificate. The logo is an output of trust you had already established, not an input to it.
- The real benefit is what you had to do to get there. You cannot have BIMI without DMARC at enforcement, and DMARC at enforcement does protect your domain and your reputation. The value is in the prerequisite.
- Display is never guaranteed, even set up perfectly. Providers apply their own reputation checks on top. A technically flawless BIMI implementation from a sender with poor engagement will show nothing.
- Where it does help is before the open. Recognition in a crowded inbox is a real effect. Your sender name and a familiar logo are doing the work in the half second somebody decides whether your email is for them, and familiarity is what makes somebody choose you when the need arrives.

 

# The process

## Six steps, in order, and the fifth one is where people stall

1. Get SPF and DKIM passing and aligned. Alignment matters as much as passing. The authenticated domain has to match the From domain your recipient sees.
2. Move DMARC to enforcement. A policy of quarantine or reject, applied to all of your mail. A policy of none does not qualify, and neither does enforcement applied to only part of your volume. Ramp it using your aggregate reports rather than switching it overnight.
3. Then wait. Providers generally want to see the policy stable at full enforcement for around thirty days before BIMI is considered. Publishing the record the same afternoon you flipped the policy achieves nothing.
4. Convert your logo to SVG Tiny PS. A specific, restricted SVG profile. A standard export from Illustrator or Figma will almost certainly fail validation, and this step surprises people more than any other.
5. Get your VMC or CMC. From a Mark Verifying Authority recognised by the BIMI Group. Expect identity verification, and for a CMC expect to evidence twelve months of prior logo use.
6. Publish the BIMI DNS record and test. A TXT record at default.\_bimi.yourdomain, pointing at the hosted SVG and the certificate, both served over HTTPS.

 

### Why is my logo not showing?

- DMARC is still at none, or not applied to all mail. The most common cause by a distance.
- The SVG is not Tiny PS. Or it is, but it no longer matches the asset the certificate authority validated. Changing the logo without revalidating breaks it.
- No certificate, and you are expecting Gmail to display it. Self-asserted works at Yahoo, not at Gmail.
- Your sending reputation is not good enough. Providers apply their own judgement on top of the technical checks.
- Or something failed silently. Which is the general case. BIMI failures do not produce errors, the logo simply does not appear, so testing is the only way to know.

 

# The cost

## What you will pay, all in

Certificates are priced in US dollars, so the figures below are approximate conversions and will move with the exchange rate. Prices checked October 2026.

- VMC, buying direct: roughly £1,100 to £1,400 a year. DigiCert sits at the top of that range, with GlobalSign and SSL.com below it.
- CMC, buying direct: roughly £800 to £1,100 a year. Same providers, consistently cheaper than their VMC equivalent.
- Through a reseller: considerably less. Reseller pricing for the same certificates runs from around £700 for a VMC and around £590 for a CMC. The gap between the cheapest reseller and the most expensive direct purchase is roughly double, for an identical product.
- So shop around, and negotiate. Published list prices are a starting position. Businesses routinely pay considerably less than the first quote they are given.

The costs nobody quotes you

- The trademark, if you want a VMC. A UK IPO application is around £170 for one class online, and takes months. Check the current fee before you budget, and factor in legal advice if the mark is at all contested.
- Getting to DMARC enforcement. Usually the largest cost by far, measured in internal time rather than invoices. For a business with several sending systems and no clear inventory, it is a project rather than a task.
- Annual renewal. A subscription, not a purchase.
- And logo changes. A rebrand means revalidating, which means paying again.

# Weighing it

## The case for and against

### For

- It forces you to finish the authentication job. Plenty of businesses have had DMARC at p=none for three years. A visible reward at the end is sometimes what gets the budget approved.
- Recognition in the inbox is real. Especially for consumer brands competing in a crowded Promotions tab where everything else looks the same.
- The blue checkmark carries weight with some audiences. A visible verification signal, from Google, that you are who you say you are.
- And it is a defence against impersonation. Not technically, since DMARC does that work, but visually. A customer who expects your logo may notice when a fake lacks it.

### Against

- No deliverability benefit. The thing most people are buying it for is the thing it does not do.
- A large share of audiences cannot see it. No Microsoft support, no roadmap. For B2B that is frequently most of your list.
- The cost recurs and the trademark gates the best version. Four figures a year, plus a months-long trademark process for the full benefit.
- Display is never guaranteed. You can do everything correctly and still show nothing, with no error message explaining why.
- And the money has alternative uses. A year of VMC costs about the same as a proper deliverability audit, and one of those two things will change your results.

# The answer

## Should you bother?

- Yes, probably. Consumer brand, Gmail and Apple-heavy audience, trademark already registered, DMARC already at enforcement. The work is mostly done and the audience can see it.
- Start with a CMC. No trademark yet, Gmail-weighted list. You get the logo where most of your audience is, for less money and without a months-long trademark application.
- Do the free version first. Already at enforcement but not sure it is worth paying? Publish a self-asserted record. Yahoo and Fastmail will display it, it costs an afternoon, and you will have the plumbing in place.
- Look at Apple Branded Mail instead. Apple-heavy audience, no trademark, no appetite for a VMC. Free, and it reaches the inbox a VMC was the only route to.
- Not yet. Still at p=none. Fix that first, because it matters more than everything else on this page combined.
- And probably not. B2B with a mostly Microsoft audience. You would be paying four figures a year for something most of your recipients cannot see.

## The conclusion

BIMI is the cherry, not the cake. The cake is authentication, list quality and sending behaviour, and a business that has those things will do perfectly well without a logo. A business that lacks them will not be rescued by one.

Where it earns its place is as the visible end of a project worth doing anyway. If the promise of a logo is what finally gets DMARC moved to enforcement in your organisation, then it has paid for itself before it ever displays.

Just do not buy it expecting your email to land better, because it will not.
