BIMI 记录生成器
Create and validate the DNS record that displays your brand logo beside your emails in the inbox, or paste an existing BIMI record to review its settings in plain English.
什么是 BIMI？
BIMI (Brand Indicators for Message Identification) is a DNS record that tells supporting inboxes such as Gmail, Apple Mail, Yahoo, and Fastmail to display your brand logo next to the messages you send. Showing your verified mark in the avatar slot makes legitimate emails easier for recipients to recognize and harder for phishers to impersonate.
BIMI builds on top of your existing email authentication. Supporting mailbox providers display your logo once your messages pass DMARC with an enforcement policy of quarantine or reject. The BIMI record itself points to two hosted files: your SVG logo and an optional certificate proving you own the mark.
DMARC 强制执行
Your domain needs an active DMARC policy set to quarantine or reject before mailbox providers will display a BIMI logo.
SVG 标志
Host a square brand logo in the SVG Tiny Portable/Secure profile over HTTPS so supporting inboxes can fetch and render it reliably.
验证标记证书
Gmail and Apple Mail require a Verified Mark Certificate (VMC) from a recognized certificate authority to confirm you own the trademark for your logo.
Publish the generated value as a TXT record at default._bimi.yourdomain.com with your DNS provider. After DNS propagation finishes, mailbox providers cache and refresh logos on their own schedules.
生成您的记录
Enter the HTTPS URL for your SVG logo and your certificate if you have one, and the DNS record updates live on the right. You can also paste an existing BIMI record to populate the form and check its syntax.
记录构建器
填写您的徽标和证书，记录会实时更新。
徽标
l您的品牌徽标的 HTTPS 链接。它必须是 SVG Tiny Portable/Secure 文件：纯色背景上的方形单路径标志。这是 BIMI 唯一不可缺少的要素。
验证标志证书
aVMC 证明您拥有徽标的商标权。Gmail 和 Apple Mail 没有该证书将不会显示徽标，但您可以先发布记录，稍后再添加证书。
DNS 记录
在您的域名下发布此 TXT 记录。
在您的 DNS 提供商处添加一条新记录。"Type" 和 "Host" 是它要求填写的字段。有些提供商只需要在 host 字段中填写 default._bimi，会自动为您补全域名。
在此粘贴现有记录，构建器将自动更新匹配。
- No a tag — Gmail and Apple Mail need a Verified Mark Certificate to display your logo.
