BIMI allows email senders from any company to authenticate their brand in the inbox. It is an **authentication protocol** that allows displaying**an image next to the sender name**on supported email clients inbox. (Yahoo only right now, Gmail is in a testing phase). ![BIMI](https://www.mailsoar.com/wp-content/uploads/2021/04/BIMI.png) ## Why you should use BIMI? Displaying an image next to your sender name has **some pros:** - **Deliverability** BIMI can really help you improve the deliverability of your mailings. By requiring stronger authentication, users and provider security systems have more trust in the email source. - **Marketing** From a marketing angle, the users who receive the authenticated emails will recognize the brand and the company at first glance. It will improve the user experience of the clients and strengthening the brand-customer relationship. - **Control** It also allows companies to control which image should be displayed: they can change the logo depending on the different events or on the season, for example. - **Protection** BIMI protects the brands and the companies’ reputations by preventing fraudulent IP use. ## BIMI requirements - **DMARC policy** You need to have a DMARC enabled on your domain, with a **quarantine (p=quarantine) or reject (p=reject) policy.** - **SVG logo** You need an SVG of your logo. Be careful, for BIMI you need a **real SVG with vectors, not only a png converted to SVG** Did you miss our last article about DMARC on our blog?

The final step is the easiest: you just need to add a **TXT record in the DNS** of your domain. Here is the structure: ``` default._bimi.[domain] IN TXT “v=BIMI1; l=[SVG URL]; a=[PEM URL]“. (a tag is optional) ``` Normally, that’s all for BIMI. If everything was configured properly, you should see the first effects within a few days. ## How MailSoar can help you with BIMI? Even if you have configured BIMI properly, it does not, unfortunately, guarantee that a recipient’s mailbox provider will display your brand logo or the image you have set up. Some providers may use other criteria like your brand reputation, anti-abuse checks, or user process to determine whether to display your logo.
