Best Practices to Improve Email Delivery with Klaviyo

To ensure optimal email delivery rates and improve the overall deliverability of your campaigns, it’s important to follow some best practices when configuring Klaviyo. Here are some key guidelines to keep in mind:

  1. Authenticate Your Domain: Authenticate your sending domain by setting up SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records. This helps establish trust with ISPs (Internet Service Providers) and reduces the likelihood of your emails being marked as spam.

  2. Maintain a Clean Email List: Regularly clean your subscriber list by removing inactive or unengaged contacts. Use Klaviyo’s built-in engagement filters to segment out subscribers who haven’t opened or interacted with your emails for a specified period.

  3. Implement Double Opt-In: Utilize double opt-in confirmation for new subscribers, where they need to confirm their subscription via an email link before being added to your mailing list. This ensures that only engaged users receive your emails and minimizes the chances of spam complaints.

  4. Monitor Sender Reputation: Keep an eye on your sender reputation using Klaviyo’s deliverability dashboard or third-party tools like Sender Score or GlockApps. Address any issues promptly, such as high bounce rates or spam complaints, which can negatively affect deliverability.

  5. Avoid Spam Trigger Words: Craft compelling subject lines and avoid using common spam trigger words that might raise red flags for ISPs’ automated filters. Be creative in communicating value without resorting to clickbait language.

  6. Personalize Your Emails: Leverage dynamic content and personalization features within Klaviyo to create tailored messages that resonate with individual recipients. Personalized emails tend to have higher open rates, leading to better overall deliverability.

7 .Test Before Sending Large Campaigns: Prioritize testing smaller segments of your list before sending large-scale campaigns across all subscribers. This allows you to identify and rectify any deliverability issues before potentially impacting your entire audience.

Remember, improving email delivery with Klaviyo is an ongoing process. Stay up-to-date with industry best practices, adapt to changing trends, and regularly review your campaigns’ performance metrics for continuous improvement.

Monitoring and Optimizing Klaviyo’s Deliverability

To ensure that your emails are reaching the intended recipients, it is essential to monitor and optimize Klaviyo’s deliverability. Here are some key steps you can take:

  1. Authentication: Implement authentication protocols like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify the authenticity of your email domain. This helps improve deliverability by reducing the chances of your emails being marked as spam.

  2. List Hygiene: Regularly clean your email list by removing inactive subscribers, invalid or bouncing email addresses, and spam traps. Maintaining a healthy list improves deliverability rates and engagement with your audience.

  3. Monitor Sender Reputation: Keep an eye on your sender reputation score using tools like Return Path or SenderScore.org. A good sender reputation indicates a positive sending history, which increases the chances of inbox placement.

  4. Deliverability Testing: Conduct regular tests to check how different ISPs (Internet Service Providers) handle your emails. Use seed lists or mailbox providers like GlockApps or Litmus to simulate delivery across various platforms and identify potential issues.

  5. Engagement Metrics Analysis: Monitor key engagement metrics such as open rates, click-through rates, and unsubscribe rates to gauge subscriber interest in your content. Low engagement may impact deliverability negatively, so focus on delivering valuable content that resonates with your audience.

  6. Feedback Loops: Set up feedback loops with major ISPs like Gmail, Yahoo!, or Outlook.com to receive notifications when users mark your emails as spam directly from their inbox. This feedback helps identify potential problems quickly and take necessary corrective measures.

7Complaint Handling Process: Establish an effective process for handling subscriber complaints promptly . Responding timely not only keeps subscribers engaged but also prevents negative impact on overall deliverability.

By implementing these monitoring techniques while optimizing Klaviyo’s configuration for improved deliverability, you can maximize the chances of your emails reaching the inbox and engage effectively with your audience.
