There are only two tags available for the BIMI-Selector email header. The BIMI-Selector header is inserted into your email header and is used to inform participating mailbox providers about the location of your logo information contained within the BIMI record for your domain.
Required tags
- v: This tag identifies the record as a BIMI record.
- The value of this tag must be BIMI1 and be the first tag listed.
- The BIMI record will be ignored if the value of this tag is empty or if it does not match BIMI1 exactly.
- s: This tag identifies the selector name used by the mailbox provider to look up your BIMI record in the DNS.
