What is SPF Permerror?

SPF=Permerror indicates that there is a fundamental problem with the SPF record, making it impossible to determine if the sending server is authorized or not.

What is the 10 DNS lookup limit?

During SPF check, every time an email is sent from your domain, your recipient’s email server performs DNS query requests, also known as DNS lookups to check the presence of authorized IP addresses in your DNS and match them to the ones in the received email’s return-path header. However, RFC limits the number of DNS lookups to 10. This is known as the 10 DNS lookup limit.

Am I exceeding SPF Too Many DNS Lookups limit?

If you are worried about exceeding the lookup limit for SPF, you can check your record instantly using our SPF record checker tool.

How to fix SPF Permerror?

A more effective way to avoid SPF errors is to deploy an SPF flattening tool that is automatic and hassle-free – like PowerSPF!

Common Mark Certificates (CMC) for Google BIMI Adoption

There is good news for new businesses who don’t want to go into the hassle of getting their logo trademarked for it to display in Gmail inboxes. The recent Google updates now allow brands with even Common Mark Certificates (CMCs) to display their BIMI logo!

Why is this a big advantage for businesses? Earlier Google required a VMC (Verified Mark Certificate) for BIMI logos to show in Gmail inboxes. VMC requires brand logos to be trademarked to establish authority, which is a time-consuming process on its own. On top of that, VMCs can leave quite a big hole in your pocket! On the other hand, CMCs are easier to obtain without the added effort of trademarking – making it a quicker and more viable option for many businesses.

Google’s Role in BIMI Adoption Expansion

Google has been one of the major pioneers in Brand Indicators for Message Identification (BIMI) adoption. Google started displaying brand avatars in customer inboxes as early as 2021. Since then, the BIMI adoption landscape has significantly expanded.

Let’s explore the recent Google changes for your brand logo to be displayed in Gmail inboxes:

Old Requirements

DMARC implementation at enforcement
Your brand logo in BIMI-compliant SVG format
Verified Mark Certificate for your trademarked logo
BIMI record configuration and logo upload

New Requirements

DMARC implementation at enforcement
Your brand logo in BIMI-compliant SVG format
A Common Mark Certificate (CMC) or a VMC
BIMI record configuration and logo upload

Summary of Recent Google Changes

As a part of Google’s recent BIMI-related developments:

Google now supports Common Mark Certificates (CMCs) for BIMI logo display.
For VMC users, Google has expanded its verification checkmark display to both mobile and desktop views, and in Gmail apps for both Android and iOS. This will gradually be rolled out in the upcoming weeks.

Primary Advantages of Google’s CMC

The primary advantage of using Google CMC for BIMI implementation is that there is now no requirement for getting your logo trademarked. CMCs are comparatively easier to obtain.

Disadvantages of Google’s CMC

With a VMC, senders will also get the blue BIMI verified checkmark, on top of their brand avatar display. CMC users will not get this feature and the verified checkmark will not appear for their emails.

What is a Common Mark Certificate (CMC)?

A Common Mark Certificate (CMC) is a type of digital certificate used to verify the ownership and authenticity of a logo or mark. It allows organizations to prove that they have been using a specific logo or brand mark for a defined period, typically for at least one year, even if the logo is not registered as a trademark. CMCs serve as a form of verification for non-trademarked logos, providing a layer of credibility and ownership without the legal protections of a trademark.

Steps to Get Your CMC for BIMI

Logo Requirements: To apply for a CMC, businesses must ensure they have used their logo for at least one year.
Email Authentication: Ensure your domain has implemented email authentication standards like DMARC, SPF, and DKIM. DMARC enforcement is required (p=quarantine or reject).
Apply Through a Provider: CMCs can be obtained through trusted certificate authorities (CAs).
Logo Validation: Your logo will be validated as part of the CMC issuance process, though this process is simpler and quicker than applying for a VMC.

Google’s CMC Vs VMC: Which One Is Better and Why?

Comparison Parameters	VMC	CMC
Application Process	Time-consuming and expensive	Easier to obtain without the hassle of logo trademarking
Eligibility	Trademarked logo	Minimum 1 year of logo usage
BIMI Verification Mark	Includes verified checkmark and brand logo display	No checkmark verification, only brand logo display
Brand Credibility	A trademarked logo is a more credible display of brand authenticity through VMC	Logos without registered trademarks offer low brand credibility and authenticity
