Email Authentication

Email fraud is a big problem for brands, businesses, and consumers alike. Spammers, spoofers, and scammers who sneak their way into an inbox can cause a lot of damage. But smart, responsible email marketers can take steps to prevent disasters.

That’s where Prelude’s email authentication services come to the rescue and provide a sense of security for both senders and recipients.

What is Email Authentication?

With email authentication, you can establish a secure connection between the email server and the sender, allowing you to better protect your business from phishing attacks, spoofing, and other malicious activities. Email authentication also helps to prevent spam and junk mail, allowing you to keep your inbox clutter-free.

By implementing email authentication, you can be sure that your emails are being sent from a legitimate source and that your recipients are receiving the content that you intended. This can help to boost your credibility and increase customer trust in your business.

Ensuring the security of your emails is essential for protecting your business and its data. Email authentication is an effective and affordable way to ensure that your emails are coming from the right source and are being sent securely. Contact us today to learn more about email authentication and how it can help protect your business.

DomainKeys Identified Mail

DomainKeys Identified Mail (DKIM) provides a unique public key that pairs with a private key. This DKIM signature is a header added to the message and secured with encryption.

Sender Policy Framework

Sender Policy Framework (SPF) is an authentication standard that verifies your identity as the email’s sender. This policy compares the sending mail server’s IP address to a list of IP addresses authorized to send mail from that domain. The SPF record is added to the sender’s DNS.

Domain Message Authentication Reporting and Conformance

Domain Message Authentication Reporting and Conformance (DMARC) is a policy for handling emails that fail SPF or DKIM authentication. This gives you more control over your email authentication system and helps protect the recipient against phishing and spoofing attacks.

Brand Indicators for Message Identification

The Brand Indicators for Message Identification (BIMI) standard attaches your brand’s logo to your authenticated emails. Behind the scenes, BIMI is a text record stored in your DNS records and contains the location of your company’s logo.

Frequently Asked Questions

What is an Email Authentication Service?

An Email Authentication Service is a set of protocols and techniques used to verify the authenticity of emails sent from a domain. It helps prevent email spoofing and phishing attacks by ensuring that emails are legitimately sent from the claimed sender.

What are SPF, DKIM, and DMARC?

SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) are three key authentication protocols:

  • SPF specifies which IP addresses are allowed to send emails on behalf of a domain.
  • DKIM adds a digital signature to emails, allowing recipients to verify that the message was not altered in transit and originated from the claimed sender.
  • DMARC builds on SPF and DKIM, providing additional policies for handling emails that fail authentication checks, such as quarantining or rejecting them.
What are the benefits of using an Email Authentication Service?

Using an Email Authentication Service offers several benefits, including increased email deliverability, reduced risk of email fraud and phishing attacks, enhanced brand reputation, and improved email security for both senders and recipients.
