In this article, we will explore various techniques and best practices to help you fine-tune your Klaviyo settings for optimal deliverability, so you can maximize the effectiveness of your email marketing efforts.

Deliverability plays a significant role in the success of any email campaign. If your emails are not reaching the recipients’ inbox, all your effort goes to waste. To address this challenge, we will cover topics such as authentication methods like DKIM and SPF records, list hygiene strategies to maintain high-quality subscriber lists, segmenting contacts based on engagement levels, and monitoring key metrics to identify delivery issues promptly. With practical tips and expert advice at hand, you’ll be equipped with the knowledge needed to optimize Klaviyo settings effectively and ensure that your emails consistently reach their destination.

Understanding Klaviyo Deliverability

To ensure that your emails reach your subscribers’ inboxes, it’s crucial to have a good understanding of Klaviyo deliverability. Here are some key points to keep in mind:

  1. Sender Reputation: Your sender reputation plays a significant role in email deliverability. ISPs (Internet Service Providers) evaluate the reputation of the sending domain and IP address to determine whether an email should be delivered or marked as spam.

  2. Authentication: Properly configuring authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) is essential for establishing trust with ISPs.

  3. List Hygiene: Maintaining a clean subscriber list is vital for good deliverability. Regularly remove inactive or unengaged contacts from your lists to avoid sending emails to invalid addresses or spam traps.

  4. Engagement Metrics: ISPs monitor recipient engagement metrics such as open rates, click-through rates, and spam reports when deciding how to treat incoming emails from specific senders. It’s important to consistently provide valuable content that encourages recipients to engage with your emails.

  5. Content Quality: Crafting well-designed and relevant content helps improve deliverability by increasing engagement rates and reducing the likelihood of being flagged as spam by ISP filters.

  6. Bounce Management: Monitor bounce codes provided by Klaviyo for each sent email campaign carefully. Soft bounces may indicate temporary issues that can be resolved, while hard bounces suggest permanent delivery failures requiring contact removal from future campaigns.

  7. ISP Feedback Loops: Take advantage of available feedback loops offered by major ISPs like Gmail or Yahoo! These feedback loops provide insights into why certain messages might be marked as spam so you can take corrective actions accordingly.

By understanding these aspects of Klaviyo deliverability, you’ll be better equipped to optimize your settings for optimal email deliverability and ensure that your messages reach the intended recipients’ inboxes. Remember to regularly review and adjust your strategies based on performance data, industry best practices, and changes in email deliverability standards.

Best Practices for Email Authentication

To ensure optimal deliverability of your emails, it is crucial to implement proper email authentication measures. By following these best practices, you can enhance the credibility and trustworthiness of your messages.

  1. Authenticate Your Domain: Start by setting up domain authentication using Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting & Conformance (DMARC). These protocols validate the authenticity of your sending domain and prevent spoofing or phishing attempts.

  2. Configure SPF Records: Create a Sender Policy Framework (SPF) record that lists all authorized IP addresses allowed to send emails on behalf of your domain. This helps receiving servers identify legitimate sources and reduces the chances of your emails being marked as spam.

  3. Implement DKIM Signatures: Implement DomainKeys Identified Mail (DKIM) signatures to digitally sign outgoing emails from your domain. This cryptographic signature ensures message integrity and verifies that the content hasn’t been tampered with during transit.

  4. Enable DMARC Enforcement: Deploying a DMARC policy allows you to specify how email providers should handle unauthenticated messages sent from your domain. By enabling DMARC enforcement, you reduce the risk of unauthorized use of your brand identity in phishing attacks.

  5. Regularly Monitor Reports: Take advantage of DMARC reporting capabilities to gain insights into email authentication failures, delivery rates, and potential abuse incidents involving your domain name. Regularly review these reports to identify any issues promptly.

  6. Keep DNS Records Updated: Ensure that all relevant DNS records related to SPF, DKIM, and DMARC are correctly set up and regularly updated whenever there are changes in infrastructure or service providers.

Remember that implementing robust email authentication practices not only improves deliverability but also safeguards against fraudulent activities associated with unauthorized use of your brand’s reputation.

Optimizing Email Content and Sending Frequency

To ensure optimal deliverability of your emails in Klaviyo, it’s important to focus on both the content of your emails and the frequency at which you send them. Here are some key tips to help you optimize these aspects:

  1. Personalize Your Emails: Customize your email content based on customer preferences, past purchases, or browsing behavior. Personalization can significantly increase engagement and improve deliverability.

  2. Keep Your Subject Lines Relevant: Craft subject lines that accurately reflect the content of your email. Misleading or spammy subject lines can lead to higher unsubscribe rates and lower deliverability.

  3. Avoid Spam Trigger Words: Be mindful of using words commonly associated with spam in your email copy. Examples include “free,” “guarantee,” or excessive use of exclamation marks (!). Use a tool like Mail-Tester to check if your emails may trigger spam filters.

  4. Optimize for Mobile Devices: Ensure that your email templates are mobile-friendly as most people now access their emails through smartphones or tablets. Test how your emails appear across different devices before sending them out.

  5. Segment Your Audience: Divide your subscriber list into smaller segments based on demographics, interests, or purchase history. This allows you to tailor the content and frequency of emails according to specific customer groups, improving relevancy and engagement.

  6. Test Different Send Times: Experiment with different days and times when sending out campaigns to determine when recipients are most likely to engage with your content.

  7. Monitor Engagement Metrics: Keep an eye on open rates, click-through rates (CTRs), bounce rates, and unsubscribes regularly through Klaviyo’s analytics dashboard. Analyzing these metrics will help you identify trends and make data-driven decisions about optimizing future campaigns.

8 .Maintain Consistency: Establish a regular cadence for sending emails while being mindful not to overload your subscribers with excessive emails. Consistency helps build anticipation and familiarity, while avoiding sending too frequently prevents list fatigue.

By following these best practices for email content and sending frequency, you can enhance deliverability rates, engage your audience effectively, and maximize the success of your Klaviyo campaigns.


In conclusion, optimizing your Klaviyo settings is crucial for ensuring optimal deliverability of your emails. By following the best practices outlined in this article, you can significantly improve your email deliverability rates and maximize the impact of your marketing campaigns.

Fine-tuning key settings such as authentication protocols, sender domains, and list hygiene will help establish trust with ISPs and increase the chances of reaching your subscribers’ inboxes.
