In today’s digital world, getting your emails to actually land in your recipient’s inbox is harder than ever. With advanced spam filters, strict email provider policies and ever changing algorithms, email deliverability is a big problem for businesses and marketers. In fact, according to a report by Validity only 83% of emails make it to the inbox and 17% get blocked or filtered into spam which means nearly 1 in 5 emails never get seen!
Email marketing generates an average ROI of $42 for every $1 spent (according to Litmus) so poor deliverability means lost revenue, missed opportunities and wasted effort. Factors like sender reputation, email authentication (SPF, DKIM and DMARC) and engagement rates all play a big part in whether your emails make it to the inbox or get lost in the void.
To stay ahead businesses need to focus on best practices – like cleaning your email lists, writing relevant content and monitoring key metrics like bounce rates and open rates. With 347 billion emails sent daily worldwide (Statista) standing out and deliverability is more important than ever.
What Factors Affect Email Deliverability?
Email deliverability goes far beyond just hitting the send button. It's the complex process of ensuring your emails successfully reach their intended destination - the recipient's inbox. This involves multiple factors, from technical setup to content quality, all working together to help your emails avoid spam folders and actually get read.
Technical Foundation for Better Deliverability
Authentication Protocols
The first step in improving deliverability is proper authentication. This involves implementing several key protocols:
SPF (Sender Policy Framework): This protocol verifies that your email is being sent from an authorized IP address. Think of it as your email's ID card, proving it's really from you.
DKIM (DomainKeys Identified Mail): This adds a digital signature to your emails, ensuring they haven't been tampered with during transit.
DMARC (Domain-based Message Authentication, Reporting & Conformance): This protocol builds on SPF and DKIM, providing clear instructions on how to handle emails that fail authentication.
Infrastructure Considerations
Building robust email infrastructure requires expertise. Many organizations work with dedicated software developers to create and maintain systems that can handle large-scale email operations while maintaining high deliverability rates. These systems need to manage everything from queue processing to bounce handling effectively.
Content That Gets Delivered
Subject Line Best Practices
Your subject line is the first impression your email makes. Here's how to make it count:
- Keep it concise and clear
- Avoid spam trigger words
- Make it relevant to the content
- Create urgency without being pushy
- Test different variations
Email Body Guidelines
The content of your email plays a crucial role in deliverability:
Maintain a Good Text-to-Image Ratio: Too many images can trigger spam filters. Aim for a balanced mix of text and images.
Use Clean HTML: Poor coding can hurt deliverability. Ensure your HTML is properly formatted and tested across different email clients.
Personalization: Include relevant personalization beyond just using the recipient's name. Consider their preferences, past interactions, and behavior.
List Hygiene and Management
Regular List Cleaning
Maintaining a clean email list is crucial for deliverability:
- Remove inactive subscribers
- Handle bounces promptly
- Verify email addresses
- Remove role-based emails
- Update changed email addresses
Engagement Metrics
Monitor and act on engagement metrics:
Open Rates: Track who's opening your emails and how often.
Click Rates: Measure interaction with your content.
Unsubscribe Rates: Watch for patterns in unsubscribes.
Spam Complaints: Address these immediately and adjust your strategy accordingly.
Sending Practices That Improve Deliverability
Proper Warming Up
When starting with a new IP address or domain:
- Begin with small send volumes
- Gradually increase sending volume
- Monitor reputation metrics
- Focus on your most engaged subscribers first
- Be consistent with sending patterns
Segmentation Strategies
Smart segmentation improves engagement and deliverability:
Engagement Levels: Separate highly engaged subscribers from less active ones.
Interest Categories: Group subscribers based on their preferences and behaviors.
Purchase History: Tailor content based on past purchases and interactions.
Monitoring and Maintaining Deliverability
Tools and Analytics
Use various tools to monitor your email performance:
Delivery Monitoring: Track where your emails are landing (inbox vs. spam).
Reputation Tracking: Keep an eye on your sender reputation across different ISPs.
Content Testing: Use tools to test your content against common spam filters.
Handling Delivery Issues
When deliverability problems arise:
- Identify the Problem:
- Check bounce rates
- Monitor spam placement
- Review authentication records
- Analyze engagement metrics
- Take Corrective Action:
- Adjust sending patterns
- Update content strategy
- Clean your lists
- Fix technical issues
Best Practices for Different Email Types
Transactional Emails
These emails need special attention to work and be effective. Using dedicated IPs for transactional mail helps with deliverability and immediate delivery is key for time sensitive communications. Keep the design simple and functional with clear sender identification to establish trust. Consistency in sending patterns helps with credibility and reliability.
Marketing Emails
A good marketing email strategy balances engagement and promotion. Prioritise value over self promotion and test different send times to find your optimal engagement times. Segment your audience so your messages are relevant to specific user groups and use dynamic content to personalise the experience. Monitor engagement metrics closely to continue to optimise.
Newsletter Best Practices
Regular newsletters require consistency in both quality and scheduling. Having a regular sending routine helps build audience expectation and retention. Valuable content keeps subscribers engaged, consistent design strengthens brand identity. Clear CTAs and easy to use unsubscribe option helps with compliance and user satisfaction.
Future Proofing Your Email Strategy
Adapting to Change
Staying ahead of email delivery trends is key to long term success. Keep track of ISP policy updates, update authentication protocols and adapt to new spam filtering techniques to maintain high deliverability. Embrace emerging engagement metrics and stay up to date with industry best practice to continue to optimise.
Mobile Optimization
Most emails are opened on mobile so optimise for smaller screens. Responsive design ensures a seamless experience across devices and concise content improves readability. Test across different screen sizes, optimise images for quick load times and add touch friendly elements to improve usability and engagement.
Legal Compliance and Trust
Following The Rules
Compliance with email laws builds credibility and avoids legal issues. Include a physical address, honour unsubscribe requests and maintain proper documentation to meet regulatory requirements. Comply with data protection rules and be transparent about data usage to build trust with your recipients.
Building Trust
Trust is the foundation of email communication. Consistency in sending reassures subscribers and delivering value strengthens relationships. Respect user preferences, be transparent in your messaging and handle data responsibly to build long term engagement and brand loyalty.
Conclusion
Email deliverability is a complex but crucial aspect of digital communication. Success requires a combination of technical expertise, content quality, and proper list management. By following these guidelines and staying updated with best practices, you can significantly improve your chances of reaching the inbox.
Remember that deliverability is not a one-time fix but an ongoing process. Regular monitoring, testing, and adjusting your strategy based on results will help maintain and improve your email deliverability over time. The key is to focus on providing value to your recipients while maintaining technical excellence in your email operations.
The future of email deliverability will likely bring new challenges and opportunities. Staying informed about industry changes and being ready to adapt your strategy will be crucial for continued success in reaching your audience's inboxes.
