Understanding Email Deliverability

Email deliverability refers to the ability of your emails to reach their intended recipients’ inboxes. It is crucial for successful email marketing campaigns. Here are some key points to help you understand email deliverability:

  1. Sender Reputation: Your sender reputation plays a significant role in determining whether your emails end up in the inbox or spam folder. Internet service providers (ISPs) evaluate factors like spam complaints, bounce rates, and engagement metrics to assess sender reputation.

  2. Authentication: Implementing authentication protocols like SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication Reporting & Conformance) can boost your email deliverability by verifying the authenticity of your emails.

  3. List Hygiene: Maintaining a clean email list is essential for good deliverability. Regularly remove inactive or bounced email addresses from your list and use double opt-in methods to ensure subscribers genuinely want to receive your emails.

  4. Content Relevance: ISPs analyze the content of your emails to determine if they are relevant and valuable for recipients. Avoid using excessive promotional language, misleading subject lines, or deceptive practices that may trigger spam filters.

  5. Engagement Metrics: ISPs consider subscriber engagement as an indicator of delivering desired content. Factors like open rates, click-through rates, and response rates influence how ISPs perceive your sending practices.

  6. Avoiding Spam Traps: Spam traps are dormant email addresses created by ISPs or anti-spam organizations to catch senders with poor data hygiene practices or those who harvest email addresses illegally. Sending messages to these traps can significantly damage deliverability.

  7. Deliverability Monitoring Tools: Utilize deliverability monitoring tools that provide insights into key metrics such as inbox placement rate (IPR), bounce rate, complaint rate, etc., helping you identify issues early on and take corrective actions.

Remember that maintaining good deliverability is an ongoing process. By following best practices, regularly monitoring your performance, and adapting to changes in email regulations, you can improve the chances of reaching your target audience’s inbox effectively.

Factors Affecting Klaviyo Deliverability

When it comes to ensuring good deliverability with Klaviyo, there are several factors that can have an impact. Understanding these factors will help you optimize your email campaigns and maximize their reach. Here are some key considerations:

  1. Sender Reputation: The reputation of the sender plays a crucial role in email deliverability. ISPs evaluate senders based on previous sending behavior, including bounce rates, spam complaints, and engagement metrics. To maintain a good reputation:

    • Send relevant content to engaged subscribers.
    • Regularly clean your subscriber list to remove inactive or unengaged contacts.
    • Monitor and address any issues promptly.

    • Personalize emails whenever possible to increase recipient engagement.
    • Optimize HTML code and ensure it renders correctly across different devices.
  3. List Quality: The quality of your subscriber list also impacts deliverability:

    • Use double opt-in methods to verify new subscribers’ intent and prevent fake or mistyped email addresses from entering your list.
    • Regularly remove hard bounces (undeliverable addresses) from your list.
    • Segment your audience based on interests, preferences, or activity levels for targeted messaging.
  4. Authentication & Infrastructure Setup: Implementing proper authentication protocols helps establish trust between ISPs and senders:

    • Set up DKIM (DomainKeys Identified Mail), SPF (Sender Policy Framework), and DMARC (Domain-based Message Authentication Reporting & Conformance) records for your domain.
    • Ensure consistent branding by aligning the “From” name, reply-to address, domain name with expectations set by recipients.
  5. Engagement Metrics: Monitoring engagement metrics provides insights into the effectiveness of your campaigns:

    • Track open rates, click-through rates (CTR), and conversion rates to gauge subscriber engagement.
    • Regularly remove inactive or unengaged subscribers from your list to maintain high engagement levels.

By considering these factors and implementing best practices, you can enhance Klaviyo deliverability and increase the chances of reaching your target audience successfully. Remember that maintaining good email deliverability requires ongoing monitoring, analysis, and adjustments as needed.
