Introduction

Are your emails mysteriously ending up in spam folders or not reaching your customers at all? You’re not alone. Over the past few years, email deliverability has become increasingly complex. Changes in email provider policies, advances in spam filter technology, and new privacy regulations have all contributed to this challenge.

In this blog post, we’ll delve into the specifics of why email deliverability has tightened up recently, provide a timeline of key changes, and offer practical solutions to help ensure your emails land where they belong—in your customers’ inboxes.

Timeline of Email Deliverability Challenges

Understanding the evolving landscape of email deliverability can help you adapt your strategies effectively. Here’s a timeline highlighting significant developments over the past few years:

2018

  • May 25, 2018: GDPR Enforcement Begins
    • What Happened: The General Data Protection Regulation (GDPR) came into effect in the European Union.
    • Impact: Stricter consent requirements for email communications meant companies had to obtain explicit permission from EU residents before sending emails. Non-compliance led to deliverability issues and legal penalties.

2019

  • Rise in DMARC Adoption
    • What Happened: Widespread implementation of DMARC (Domain-based Message Authentication, Reporting, and Conformance) policies with strict enforcement.
    • Impact: Emails failing DMARC authentication were more likely to be rejected or sent to spam folders. Proper configuration of SPF, DKIM, and DMARC became essential.

2020

  • Advanced Spam Filters with AI
    • What Happened: Email providers enhanced spam filters using artificial intelligence and machine learning.
    • Impact: Increased scrutiny of email content and sender behavior led to legitimate emails being flagged as spam if they resembled suspicious patterns.
  • July 2020: Gmail’s BIMI Pilot Program
    • What Happened: Gmail launched a pilot for Brand Indicators for Message Identification (BIMI).
    • Impact: Encouraged brands to adopt strong authentication protocols. BIMI adoption improved brand recognition but required strict email authentication.

2021

  • September 2021: Apple Mail Privacy Protection (MPP)
    • What Happened: Apple released iOS 15 with Mail Privacy Protection features.
    • Impact: Masked email open rates and IP addresses, affecting tracking and engagement metrics crucial for deliverability optimization.
  • Gmail Expands BIMI Support
    • What Happened: Gmail rolled out BIMI support to all users.
    • Impact: Increased emphasis on email authentication and security, affecting deliverability for brands without proper setup.

2022

  • Stricter Enforcement of Email Authentication
    • What Happened: Google and Microsoft began enforcing SPF, DKIM, and DMARC more rigorously.
    • Impact: Emails without proper authentication were increasingly filtered out or rejected.
  • Enhanced Focus on User Engagement
    • What Happened: Email algorithms placed more weight on recipient engagement metrics.
    • Impact: Low engagement rates negatively affected sender reputation, leading to emails being sent to spam.

2023

  • January 2023: Yahoo Updates DMARC Policy
    • What Happened: Yahoo changed its DMARC policy to a stricter “p=reject.”
    • Impact: Emails failing authentication were rejected, making proper email configuration more critical.
  • March 2023: Gmail Implements New Bulk Sender Guidelines
    • What Happened: Gmail updated its Bulk Sender Guidelines.
    • Impact: Bulk senders had to meet higher standards for authentication and engagement, with non-compliance leading to increased spam filtering.
  • Increased Regulatory Scrutiny
    • What Happened: New privacy laws and stricter enforcement of existing ones (e.g., California Consumer Privacy Act).
    • Impact: Tighter regulations on data usage and consent affected email list management and deliverability.

2024

  • Ongoing AI and Machine Learning Enhancements
    • What Happened: Email providers continued refining spam filters with advanced technologies.
    • Impact: Constant evolution of filtering criteria required senders to stay updated on best practices.
  • Adoption of MTA-STS and TLS Reporting
    • What Happened: Growing implementation of Mail Transfer Agent Strict Transport Security (MTA-STS) and TLS Reporting.
    • Impact: Enhanced email security but added complexity to email server configurations.

Why Emails Are Landing in Spam

Several factors contribute to emails ending up in spam folders:

  1. Stricter Email Authentication Enforcement
    • SPF, DKIM, and DMARC records must be correctly configured.
    • Misalignment leads to emails being rejected or marked as spam.
  2. Advanced Spam Filtering Technologies
    • AI-driven filters analyze sender reputation, content, and engagement.
    • Requires adherence to best practices in content and sending behavior.
  3. Privacy Regulations
    • Laws like GDPR and CCPA impose strict consent and data handling requirements.
    • Non-compliance can result in legal penalties and deliverability issues.
  4. User Engagement Metrics
    • Providers consider opens, clicks, and replies in filtering decisions.
    • Low engagement harms sender reputation.
  5. Security Protocols
    • TLS Encryption and MTA-STS are increasingly expected.
    • Emails sent without proper security measures may be considered unsafe.

How to Fix Email Deliverability Issues

Improving email deliverability involves a combination of technical configurations, content optimization, and strategic list management. Here’s how you can address the issues:

Setting Up SPF Records

Sender Policy Framework (SPF) allows you to specify which IP addresses are authorized to send emails on behalf of your domain.

  • How to Set Up SPF:
    1. Identify all IP addresses and servers that send emails for your domain.
    2. Create an SPF record in your domain’s DNS settings.
    3. The SPF record is a TXT record that looks like:
      v=spf1 ip4:192.0.2.0/24 include:mail.yourdomain.com -all
    4. Use SPF validation tools to ensure it’s correctly configured.

Implementing DKIM Authentication

DomainKeys Identified Mail (DKIM) adds a digital signature to your emails, allowing recipients to verify they were sent by you.

  • How to Implement DKIM:
    1. Generate a public-private key pair using your email server or service provider.
    2. Publish the public key in your DNS as a TXT record.
    3. Configure your email server to sign outgoing emails with the private key.
    4. Test the DKIM setup to confirm it’s working properly.

Configuring DMARC Policies

DMARC builds on SPF and DKIM to provide instructions to email providers on how to handle unauthenticated emails.

  • How to Configure DMARC:
    1. Ensure SPF and DKIM are properly set up.
    2. Create a DMARC record in your DNS settings.
    3. The DMARC record is a TXT record that might look like:
      v=DMARC1; p=none; rua=mailto:postmaster@yourdomain.com
    4. Start with a “p=none” policy to monitor without affecting delivery.
    5. Analyze DMARC reports and gradually move to “p=quarantine” or “p=reject” policies.

Enhancing Email Content and Relevance

  • Personalize Your Emails:
    • Use the recipient’s name and tailor content to their interests.
  • Avoid Spam Trigger Words:
    • Steer clear of phrases like “Free money,” “Act now,” or “Risk-free.”
  • Optimize Formatting:
    • Use clean HTML code and ensure your emails are mobile-friendly.
  • Include a Clear Unsubscribe Link:
    • Make it easy for users to opt out to reduce spam complaints.

Maintaining a Healthy Email List

  • Regularly Clean Your List:
    • Remove inactive or unengaged subscribers.
  • Use Double Opt-In:
    • Confirm subscriptions to ensure consent.
  • Segment Your Audience:
    • Send relevant content to specific groups to increase engagement.

How to Test Your Email Deliverability

Testing your emails before sending them to your entire list can help identify potential issues.

  • Use Mail-Tester.com:
    • Send your email to the address provided by Mail-Tester.com.
    • Review the detailed report, which scores your email on spamminess, authentication, and content.
    • Address any issues highlighted in the report.
  • Check with Gmail and Outlook Tools:
    • Gmail Postmaster Tools: Monitor your domain’s reputation and performance.
    • Microsoft SNDS (Smart Network Data Services): Provides data on your sending IP’s reputation.
  • Test Across Multiple Providers:
    • Ensure your emails render correctly and aren’t flagged as spam by sending test emails to accounts with different providers (e.g., Gmail, Yahoo, Outlook).

Conclusion

Email deliverability has become more challenging due to evolving technologies, stricter policies, and enhanced security measures. However, by understanding these changes and implementing best practices, you can significantly improve your chances of reaching your customers’ inboxes.
