BIMI is a new email authentication standard that allows a brand’s logo to be displayed next to its messages in recipients’ inboxes. <\/strong><\/p>\n\n

The acronym BIMI stands for Brand Indicators for Message Identification<\/strong>. <\/p>\n\n

Essentially, BIMI adds an extra layer of security and brand recognition<\/strong> to your email marketing<\/strong> campaigns: when you send an email, if your domain is properly authenticated, your company logo is displayed as the sender’s avatar, providing visibility and trust.<\/strong><\/p>\n\n

This protocol works in conjunction with existing authentication systems (primarily SPF<\/a>, DKIM<\/a>, and DMARC<\/a>). <\/p>\n\n

First, you ensure your emails are authenticated<\/strong> using these technologies; then, BIMI uses that verification to confirm that the message truly comes from your organization. <\/p>\n\n

Once verified<\/strong>, major supported email providers and clients (such as Gmail<\/a>, Yahoo Mail<\/a>, or Apple Mail) will display your brand logo next to the message<\/strong>. <\/p>\n\n

This way, users can recognize at a glance who is sending the email<\/strong>, which is highly useful for differentiating your legitimate communications from phishing attempts or spam.<\/p>\n\n

In other words, BIMI gives your company control over the image that appears in the user’s inbox. <\/p>\n\n

Previously, many emails only displayed generic initials or default icons<\/strong>; with BIMI, you can ensure that your subscribers identify your actual logo when checking their emails. <\/p>\n\n

This not only reinforces your brand’s presence in the email channel but also improves the overall security of the email ecosystem by making it easier to identify trusted senders.<\/p>\n\n

Benefits of implementing BIMI in email marketing<\/h2>\n\n

Adopting BIMI <\/strong>brings multiple advantages from both a marketing and security standpoint. <\/p>\n\n

Here are the main benefits of implementing BIMI in your email campaigns:<\/p>\n\n

Increased trust and credibility: <\/h3>\n\n

Seeing your company logo allows recipients to immediately recognize the sender. <\/strong><\/p>\n\n

This visual recognition builds trust, as it confirms the email truly comes from a legitimate source (your brand) and not an impersonator. <\/p>\n\n

In times when phishing<\/a> and fraudulent emails are common, this visual seal of authenticity provides peace of mind to your subscribers.<\/p>\n\n

Strengthened brand identity: <\/h3>\n\n

BIMI turns every email into a branding opportunity. <\/p>\n\n

Having your logo present in the inbox<\/strong> reinforces your brand identity in the consumer’s mind. <\/p>\n\n

Even if the user doesn’t open the email immediately<\/strong>, they will see your corporate emblem, helping to keep your company top-of-mind and recognizable. <\/p>\n\n

This differentiates you from other messages<\/strong> in the same inbox that lack any visual brand elements.<\/p>\n\n

Potential improvement in open rates: <\/h3>\n\n

While the success of an email campaign depends on many factors (content relevance, an engaging subject line, proper segmentation, etc.), having your logo visible can positively influence<\/strong> open rates. <\/p>\n\n

Subscribers might feel more inclined to open an email if they clearly identify that it comes from a brand they know and trust. <\/p>\n\n

In early studies, companies that adopted BIMI have observed increases in user interaction with their emails, including more opens and clicks.<\/p>\n\n

Higher deliverability and sender reputation: <\/h3>\n\n

Implementing BIMI implies that you have taken the necessary steps to properly authenticate your domains (SPF, DKIM, and DMARC). <\/p>\n\n

These protocols and the BIMI policy send a strong signal to email providers<\/a> that you are a reliable sender. <\/p>\n\n

As a result, it improves your sending reputation<\/strong>, which can translate into better deliverability (meaning more emails reaching the inbox<\/strong> rather than the spam folder). <\/p>\n\n

In short, BIMI helps demonstrate to services like Gmail or Outlook that your messages are legitimate, making it easier for them to pass security filters.<\/p>\n\n

Differentiation from the competition: <\/h3>\n\n

Relatively few companies have incorporated BIMI into their email strategies so far. <\/p>\n\n

If you decide to use it, your brand will visually stand out among many other emails in your customers’ inboxes. <\/p>\n\n

This differentiation can give you a competitive edge, as your campaigns will look more professional and polished by displaying your organization’s verified logo. <\/p>\n\n

In information-saturated markets, any element that draws positive attention adds points toward getting your message noticed.<\/p>\n\n

Together, these benefits make BIMI an attractive addition to any modern email marketing strategy. <\/p>\n\n

It combines branding improvements with increased security and potentially higher campaign performance, all with a relatively straightforward implementation if you already meet the authentication requirements.<\/p>\n\n

How do you implement BIMI?<\/h2>\n\n

Implementing BIMI requires meeting certain technical requirements and following a series of steps to configure it correctly. <\/p>\n\n

Although it might sound complex, once set up, maintenance is minimal. <\/p>\n\n

Below are the basic steps to start using BIMI on your domain:<\/p>\n\n

Authenticate your domain with SPF, DKIM, and DMARC: <\/h3>\n\n

The first thing is to ensure that your sending domain is properly authenticated. <\/p>\n\n

You must have valid SPF and DKIM records in your DNS, and configure an active DMARC policy. <\/p>\n\n

Important: the DMARC policy must be set to “quarantine” or “reject” (not “none”)<\/strong>, as BIMI only works if you are actively applying DMARC protection to your messages.<\/p>\n\n

Prepare the logo in the appropriate SVG format: <\/h3>\n\n

BIMI uses a vector image file of your logo. <\/strong><\/p>\n\n

You will need to convert your logo to SVG Tiny PS format<\/strong> (a specific SVG version recommended for BIMI). <\/p>\n\n

The logo must meet certain criteria: <\/strong><\/p>\n\n

    \n
  • Be square (1:1 aspect ratio)<\/li>\n\n\n\n
  • Transparent background<\/li>\n\n\n\n
  • No small text (as it wouldn’t be legible when displayed at a reduced size) <\/li>\n\n\n\n
  • And preferably under ~32 KB in size to ensure fast loading<\/li>\n<\/ul>\n\n

    Basically, it should be a simplified and clear version of your logo that looks good at icon size.<\/p>\n\n

    Obtain a Verified Mark Certificate (optional but recommended): <\/h3>\n\n

    Some email providers, especially Gmail, require a Verified Mark Certificate (VMC) or a Common Mark Certificate (CMC) to display the BIMI logo<\/strong>. <\/p>\n\n

    These digital certificates, issued by certificate authorities, confirm that you legally own the logo and the brand. <\/p>\n\n

    While obtaining a traditional VMC<\/strong> can be costly and requires your logo to be a registered trademark, CMCs<\/strong> (a more affordable alternative that doesn’t require a registered trademark) have recently been introduced to facilitate BIMI adoption by smaller companies. <\/p>\n\n

    Having one of these certificates <\/strong>will increase the likelihood that your logo is displayed across all supported email clients.<\/p>\n\n

    Publish the BIMI record in your DNS: <\/h3>\n\n

    With all the above ready, you must add a BIMI TXT record to your domain’s DNS configuration. <\/p>\n\n

    By convention, this record is created using a default selector named default._bimi. <\/p>\n\n

    In the content (value) of the TXT record, you will include at least the version and the URL of your SVG logo. <\/p>\n\n

    For example, a basic BIMI record might look like this:<\/p>\n\n

    default._bimi.yourdomain.com TXT “v=BIMI1; l=https:\/\/tudominio.com\/ruta\/logo.svg; a=https:\/\/ruta\/vmc.pem”<\/em><\/p>\n\n

    Where v=BIMI1 indicates the version, l= points to the public location of your SVG file, and a= (optional) points to the VMC\/CMC certificate in PEM format if you have one. <\/p>\n\n

    After publishing this record, it may take a few hours to propagate.<\/p>\n\n

    Verify the configuration: <\/h3>\n\n

    Once the record is added, it is advisable to check that everything is in order. <\/p>\n\n

    You can use online tools (like the BIMI Group’s BIMI Inspector, or DNS checkers) to validate that your BIMI record is properly formatted and accessible. <\/p>\n\n

    These tools will tell you if your SPF\/DKIM\/DMARC protocols are correct and if the logo meets the requirements. <\/p>\n\n

    If everything is fine, all that’s left is to wait for the major providers to detect your BIMI. <\/p>\n\n

    Keep in mind that each provider updates their records on different schedules, so the logo won’t be immediately displayed in all cases (it can take 24-48 hours after correct configuration).<\/p>\n\n

    Once these steps are completed, your email campaigns will start displaying the logo to users on platforms that support BIMI. <\/p>\n\n

    Currently, services like Gmail, Yahoo Mail, and the Apple Mail app<\/strong> support this feature, covering a large portion of email users worldwide. <\/p>\n\n

    On the other hand, Outlook.com and other Microsoft services don’t currently offer this feature, so your emails will continue to be displayed without a custom logo on those platforms. <\/p>\n\n

    Even so, by implementing BIMI you are improving the authentication and security of your domain for all email providers, which is beneficial overall.<\/p>\n\n

    Conclusion<\/h2>\n\n

    BIMI represents an interesting convergence of marketing and cybersecurity in the email space. <\/p>\n\n

    On the one hand, it adds value to email marketing strategies by making your communications more eye-catching and aligned with your brand identity. <\/p>\n\n

    On the other hand, it elevates the level of security, since using it requires following email authentication best practices, making it harder for malicious third parties to spoof your identity.<\/p>\n\n

    Although its implementation requires some technical coordination (especially in DNS and certificate configuration), the results can be well worth it. <\/p>\n\n

    Imagine the professional impression you give the recipient when they see your official logo in their inbox<\/strong>: it conveys reliability, trust, and a commitment to transparency. <\/p>\n\n

    Additionally, since it is still relatively new, taking advantage of BIMI can differentiate you in a crowded inbox, increasing the chances that your messages will be opened and remembered.<\/p>\n\n

    Ultimately, BIMI is a modern and growing tool that any company focused on email marketing should consider. <\/p>\n\n

    If you already properly manage your email authentication, making the leap to BIMI is the logical next step to boost both deliverability and your brand image in every email you send. <\/p>\n","protected":false},"template":"","class_list":["post-90046","glossary","type-glossary","status-publish","hentry"],"yoast_head":"\nBIMI -
