Cloudflare’s new SPF, DKIM, and DMARC requirements
by DuoCircle
Starting July 3, 2025, Cloudflare requires all emails to be authenticated using at least one of the protocols. SPF or DKIM, to forward them. This requirement has been imposed in consideration of the growing number of email-based phishing and spoofing attacks. These email authentication protocols ensure that only authorized emails reach the inboxes of recipients, thereby preventing them from being manipulated into transferring money or sharing confidential information.
Email communication has become a vital part of our daily lives, especially for businesses. But did you know that a simple yet crucial security feature can help protect your emails from being tampered with or falsely represented? That’s where DKIM (DomainKeys Identified Mail) comes in. This method adds a digital signature to your email, giving both you and your recipients peace of mind that messages are authentic and safe.

If you are struggling with disappearing emails or deliverability drops when targeting Microsoft 365 users, then it’s an indication of an underlying issue— misconfigured or missing email authentication protocols.
Email has become a central tool for communication, but with its convenience comes the risk of impersonation and spam. Many people don’t realize that proper email setup is crucial to keep their messages safe and trusted. One of the best ways to protect your domain from being misused is through an SPF record. Think of it as a security badge that tells other mail servers which addresses are allowed to send emails on your behalf.

Stay digitally safe and well-informed about your personal information security!
As we move further into the digital age, there is a growing appetite for brands to build a relationship with their audience by reaching them with personalized communication. Email marketing is a powerful weapon, but most people have never been able to figure out how to conduct email campaigns manually or with high-end tools. Once organizations understand why email marketing software works better than manual efforts, they can redirect their efforts into more effective ways.
When it comes to B2B and B2C business communications, email plays a crucial role as a core communication channel. From running marketing campaigns to offering customer support, from notifying customers with transactional details to engaging them one-on-one with newsletters and emails, they do it all for your business.
But what if these emails do not reach your audience at all? Poor email deliverability can not only affect your day-to-day business operations but also tarnish your brand reputation. This is exactly why you need DMARC to enhance your email deliverability.
Let’s find out how your email deliverability is dependent on DMARC.
