How do I set up Complaint Feedback Loop (CFL) within Yahoo SenderHub with DKIM domain, and why is my BIMI logo not showing?
Summary
What email marketers say8Marketer opinions
Email marketer from Reddit shares that if your BIMI logo isn't showing, double-check your SVG file. Ensure it's correctly formatted, publicly accessible, and meets all the BIMI specification requirements. Also, verify that your VMC (if used) is valid.
Email marketer from GMass shares that SenderHub helps to monitor complaints. Ensuring that your DKIM is setup correctly allows the feedback loop to function correctly.
Email marketer from EmailOnAcid mentions that various factors influence BIMI logo display. These factors include the email client, the sender's reputation, and any rendering issues within the email client itself. Thorough testing is essential to identify any potential issues.
Email marketer from Mailhardener shares that for Yahoo's CFL to function, the DKIM signature domain must match the domain you're enrolling in Sender Hub. This ensures that Yahoo can accurately attribute complaint feedback to your sending domain.
Email marketer from OnlyMyEmail explains that correctly configuring BIMI involves creating a DNS TXT record, hosting an SVG version of your logo, and possibly obtaining a Verified Mark Certificate (VMC). Even with all this in place, the logo's display is at the discretion of the email provider.
Email marketer from Litmus recommends using BIMI validators to check the correct configuration of your BIMI DNS record and SVG logo. This helps ensure that your BIMI setup meets the required specifications and increases the chances of your logo being displayed.
Email marketer from EmailGeek recommends that to troubleshoot your BIMI issues ensure that your DNS is valid using a BIMI validator. Then ensure your logo is valid, ensure you use a VMC and finally ensure your DMARC is setup.
Email marketer from StackOverflow answers that the DKIM domain needs to be aligned with the envelope From domain (Return-Path) for the CFL to work correctly. This alignment ensures that the feedback loop can accurately identify and process complaints related to your email sending practices.
What the experts say6Expert opinions
Expert from Email Geeks confirms that marketing.notcutts.co.uk *is* a subdomain of notcutts.co.uk and that the sp=none tag indicates that any subdomains of marketing.notcutts.co.uk have a DMARC policy of none.
Expert from Email Geeks explains that there needs to be a direct match with the DKIM domain for the Yahoo SenderHub Complaint Feedback Loop (CFL). Recommends enrolling the DKIM domain (cd.marketing.nocutts.co.uk) in the CFL for the easiest path.
Expert from Word to the Wise explains that if your BIMI record is set at the organizational domain level, but you're sending from subdomains, you need to ensure that the subdomains either inherit the organizational BIMI record properly (which depends on DMARC policy) or have their own BIMI record. The absence of a correctly configured BIMI record for the sending subdomain is a common reason for the logo not showing.
Expert from Email Geeks shares that the BIMI logo is not guaranteed to display, even with correct technical setup. Mail clients decide when to display it based on factors beyond the sender's control, such as reputation. The sender's responsibility is to set it up correctly, obtain required certifications, and maintain a high reputation.
Expert from Word to the Wise mentions that after publishing the BIMI record, test it through a BIMI validator which diagnoses common mistakes. Validators exist to check the record and make sure the logo passes all the requirements.
Expert from Email Geeks clarifies that subdomains will not inherit the BIMI logo due to the `sp=none` tag. However, for the current email setup, it's not a concern as the email is authenticated, aligned, and has a `p=reject` policy.
What the documentation says5Technical articles
Documentation from DMARC.org emphasizes that BIMI requires a DMARC policy of 'p=quarantine' or 'p=reject'. The BIMI logo will not display if the DMARC policy is set to 'p=none'. This is because BIMI relies on DMARC to verify the sender's authenticity and prevent spoofing.
Documentation from RFC explains that DMARC policy enforcement (p=quarantine/reject) is crucial for BIMI, as it provides a mechanism for mailbox providers to trust that the sending domain has implemented security measures to prevent email spoofing.
Documentation from Microsoft shares that BIMI is used in conjunction with DMARC authentication. A DMARC policy needs to be setup so the mail server knows to trust the brand. Brands should follow best practice with BIMI records, SVG images, and DMARC to ensure it works.
Documentation from Yahoo explains that to set up the Complaint Feedback Loop (CFL) in Yahoo Sender Hub, you need to ensure your DKIM domain is correctly aligned with the domain used in the 'From' header of your emails. The CFL uses the DKIM domain to identify the sender and associate feedback reports.
Documentation from BIMI Group highlights that a BIMI logo might not display even with correct setup due to several factors. These include the recipient's email client supporting BIMI, the recipient's settings, and the sender's reputation. Ensuring DMARC compliance with a policy of 'p=quarantine' or 'p=reject' is a prerequisite.
