No matter what type of business you have: email marketing remains a fundamental part of your sales. The Inbound Marketing landscape for this year will feature significant changes brought by Gmail and Yahoo that will drastically impact your email marketing starting in February 2024.

We will explain here the new email marketing rules imposed by providers like Gmail and Yahoo, focusing on email authentications, maintaining low spam rates, adherence to technical standards, prohibition of impersonation, implementation of additional security, and unsubscribe practices. These guidelines are essential to avoid penalties and ensure effective email delivery. Discover here how you should adapt to these changes.

For those short on time, here’s a summary:

  • The importance of email authentications like SPF and DKIM for the sender's domain.
  • The need for valid DNS records for sending domains or IPs, including PTR records.
  • Keep spam rates below 0.3%, as indicated in the Postmaster Tools.
  • Adherence to the Internet Message Format standard (RFC 5322) for message structure.
  • Prohibition of impersonation of the “From:” headers in Gmail.
  • The addition of ARC headers in forwarded emails.
  • Implementation of DMARC authentication for the sending domain.
  • Alignment of the domain in the “From:” header with the SPF or DKIM domain.
  • Enabling one-click unsubscribe options and including a visible unsubscribe link in the body of the message.
  • Using a TLS connection for email transmission.

How Will This Change Email Marketing Practices?

To ensure the effectiveness of your email marketing campaigns and compliance with the new rules from major providers like Gmail and Yahoo, it is essential to adopt best practices and strictly follow the technical guidelines.

The technical guidelines include the correct implementation of email authentications such as SPF, DKIM, and DMARC, and maintaining spam rates below the established limits. Additionally, it is important to ensure the security of sent emails through TLS and facilitate the unsubscribe process for users.

Adopting these measures not only improves email delivery but also builds user trust and enhances the sender's reputation in the long run.

New Requirements for Senders

The new requirements for senders established by major email providers like Gmail and Yahoo! represent a significant change in the email marketing landscape in 2024. With the implementation of these requirements, senders will need to adopt stricter practices to ensure the effective delivery of their messages to recipients.

From setting up SPF and DKIM email authentication to maintaining spam rates below 0.3%, each requirement aims to improve the security, authenticity, and relevance of the sent email messages.

Moreover, the inclusion of policies like DMARC and the requirement for domain alignment for signed messages reflect the growing concern for sender authenticity and the prevention of spoofing and phishing practices. These measures aim to protect end users from unwanted and potentially malicious emails.

Consequences of Non-Compliance

The consequences of non-compliance with the new requirements established by major email providers can be significant for senders. With increased scrutiny and the enforcement of stricter policies, senders who do not adapt to the new requirements will face a series of challenges.

Firstly, non-compliance may result in temporary email delivery errors, affecting senders' ability to effectively reach their recipients. Over time, these errors may evolve into a gradual rejection of non-compliant messages, further reducing delivery capacity.

Additionally, the sender's reputation may be harmed, affecting their ability to send future emails and their credibility with email providers. This can directly impact the performance of their email marketing campaigns and the effectiveness of the company's communication strategies.

Gradual Progression of Measures

The gradual progression of measures established by email providers represents a strategic approach to ensure sender compliance with the new requirements. By starting with temporary email delivery errors for non-compliant senders, providers offer an opportunity for senders to adjust their practices and comply with the new requirements.

This progressive approach allows senders time to understand and implement the necessary changes in their email marketing strategies. Over time, the gradual rejection of non-compliant messages encourages senders to take proactive measures to ensure compliance and improve the quality of their email campaigns.

This gradual progression also provides an opportunity for senders to continuously evaluate their performance and make adjustments as needed. By adapting to the new requirements incrementally, senders can minimize disruptions in email delivery and maintain the effectiveness of their communication strategies with customers.

Transforming Best Practices into Requirements

The transformation of best practices into requirements by major email providers like Gmail and Yahoo! marks a significant change in the email marketing landscape in 2024. These requirements reflect not only recommended practices but also essential standards that senders must follow to ensure the effective delivery of their messages to recipients.

By codifying these best practices into applicable requirements, email providers are raising the standard of security, authenticity, and relevance of sent email messages. This includes everything from setting up SPF and DKIM email authentication to the implementation of policies like DMARC and domain alignment for signed messages.

This approach not only strengthens the security of the email ecosystem but also creates a more trustworthy and transparent environment for end users. By transforming best practices into requirements, email providers are promoting a culture of responsibility and integrity among senders, ensuring that only legitimate and relevant messages reach users' inboxes.

SPF and DKIM Email Authentication

SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail) email authentication is fundamental to ensuring the security and legitimacy of email messages. SPF allows email providers to verify whether a particular email server is authorized to send messages on behalf of a specific domain.

Meanwhile, DKIM uses cryptography to digitally sign messages, allowing recipients to verify their authenticity. The correct implementation of these authentication methods is essential to achieve compliance with the new requirements and ensure the effective delivery of email marketing campaigns.

Valid Forwarding and Reverse DNS Records

Valid forwarding and reverse DNS records play a very important role in the authentication and effective delivery of emails. The forwarding DNS record, also known as SPF, allows email providers to verify whether a particular email server is authorized to send messages on behalf of a specific domain.

On the other hand, the reverse DNS record, or PTR, helps verify the authenticity of the sender, allowing recipients to check whether the originating IP address is associated with the sender's domain.

Ensuring that these records are correctly configured is essential to achieve compliance with the requirements of email providers and ensure the effective delivery of email marketing campaigns.

Maintaining Spam Rates Below 0.3%

Keeping spam rates below 0.3% is essential to ensure the effectiveness of email marketing campaigns and the reliable delivery of messages to recipients. Spam complaint rates above this limit can result in penalties, such as temporary delivery errors or even rejection of messages by email providers.

To avoid this, senders should adopt practices that promote the relevance and legitimacy of their emails, such as sending quality content, properly segmenting the contact list, and providing clear unsubscribe options.

Additionally, regularly monitoring spam complaint rates and promptly addressing any issues is crucial to maintaining a positive reputation as an email sender.

Formatting According to Internet Message Format Standard (RFC 5322)

Formatting according to the Internet Message Format standard (RFC 5322) is essential to ensure that email messages are correctly interpreted by email servers and clients. This standard establishes guidelines for the structure and format of headers, body, and attachments of email messages. Following these guidelines is fundamental to ensure the effective delivery of messages and avoid formatting issues that could impair the readability or authenticity of messages.

By ensuring that messages comply with RFC 5322, senders can increase the likelihood of their messages being successfully delivered and being perceived as legitimate by recipients and email providers.

Domain Alignment for Signed Messages

Domain alignment for signed messages is a practice to ensure the authenticity and security of email messages. This technique involves ensuring that the domain included in the “From:” header of an email aligns with the domain authenticated by SPF or DKIM. By verifying this match between the domain in the “From:” header and the authentication records, email providers can verify the legitimacy of the sender and reduce the risk of spoofing or phishing.

Ensuring domain alignment is essential to achieve compliance with the requirements of email providers and to ensure the reliable delivery of messages to recipients.

Implementing DMARC for Sending Domains

Implementing DMARC (Domain-based Message Authentication, Reporting & Conformance) for sending domains is an essential measure to strengthen the authenticity and security of email messages. DMARC allows senders to communicate a policy to email providers, indicating how they should handle messages that fail SPF, DKIM, or both checks.

By implementing DMARC for their sending domains, senders can protect their reputation, reduce the risk of spoofing and phishing, and ensure the reliable delivery of their messages to recipients.

Including One-Click Unsubscribe

Including one-click unsubscribe in email marketing campaigns is a recommended practice to provide a more convenient experience for subscribers. This feature allows recipients to easily unsubscribe from an email list by clicking a single link, without the need to send cancellation request emails.

In addition to improving user experience, including one-click unsubscribe can help senders reduce spam complaint rates and maintain compliance with data privacy regulations.

Using TLS Connection for Email Transmission

Using a TLS (Transport Layer Security) connection for email transmission is a recommended practice to ensure the security and privacy of online communications. TLS is a security protocol that provides data encryption during transmission over the Internet, preventing third parties from intercepting or manipulating the content of messages.

By using TLS connections to send emails, senders can protect their confidential information and ensure that their messages are securely delivered to recipients. This practice is also essential to maintain compliance with data privacy regulations, such as the LGPD – General Data Protection Law.
