Understanding Email Deliverability

To ensure high deliverability with Klaviyo, it’s essential to understand the factors that influence email deliverability. Here are some key points to keep in mind:

  1. Sender Reputation: Your sender reputation plays a crucial role in determining whether your emails reach their intended recipients’ inboxes or end up in spam folders. Maintain a positive sender reputation by following best practices such as sending relevant and engaging content, avoiding excessive use of promotional language, regularly cleaning your subscriber list, and promptly addressing any spam complaints.

  2. Authentication: Implementing authentication protocols like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) helps verify the authenticity of your emails and improves deliverability. These protocols add an extra layer of trust for mailbox providers when receiving your messages.

  3. List Quality: The quality of your email list directly impacts deliverability rates. Avoid purchasing or using non-opted-in lists, as they often contain invalid or inactive addresses that can harm your sender reputation. Instead, focus on building an organic list through opt-in forms on your website and providing valuable incentives for subscribers.

  4. Engagement Metrics: Monitoring engagement metrics is vital for maintaining good deliverability rates over time. Pay attention to metrics like open rates, click-through rates (CTR), bounces, unsubscribes, and spam complaints to identify areas where improvements can be made.

  5. Bounce Management: Managing bounced emails is critical for maintaining a healthy sending reputation. Regularly remove hard bounce addresses from your list as they indicate invalid or nonexistent email accounts. Soft bounces may be temporary issues but should also be monitored closely.

6 .Content Optimization: Crafting well-designed emails with relevant content improves engagement levels while reducing the likelihood of being marked as spam by recipients. Personalize subject lines and body text whenever possible to increase relevance and appeal to subscribers.

Remember that email deliverability is not solely dependent on Klaviyo but also influenced by your practices and strategies. Understanding these factors will help you optimize your email campaigns for better deliverability and reach a larger audience effectively.
