When it comes to successful digital outreach, Klaviyo Email Marketing sets the gold standard in targeting, personalization, and deliverability. Yet even the most sophisticated marketing strategies can fall short if emails don’t reach the inbox. That’s why understanding and applying Email Deliverability Best Practices is critical to maximizing the ROI of your email campaigns.
In this comprehensive guide, we’ll explore how expert marketers and agencies can ensure their Klaviyo emails not only get delivered—but actually get opened and acted upon.
Email deliverability is more than just sending emails—it's about making sure your messages land in your recipient’s inbox instead of the spam folder. For businesses leveraging Klaviyo Email Marketing, this is a foundational success metric.
Deliverability hinges on a combination of sender reputation, list hygiene, engagement rates, and technical setup. If you're seeing low open rates or bounce rates climbing, it's likely time to reassess your approach.
Companies that invest in cold email outreach, website design services, and SEO services often overlook the crucial role deliverability plays in tying all digital channels together. Even the best-designed landing page is useless if no one sees the email that links to it.
That’s why brands that run integrated strategies—using tools like Google Ads to grow email lists while optimizing deliverability—see better performance across the board.
A vital first step is authenticating your sending domain using SPF, DKIM, and DMARC records. Klaviyo provides step-by-step instructions, but the key takeaway is this: authentication builds trust with inbox providers like Gmail and Outlook.
Without proper setup, your emails may be filtered out before they even reach the inbox.
Deliverability is directly tied to how your audience interacts with your emails. Klaviyo makes it easy to segment your list by behavior, demographics, and purchase history.
Focus on sending content to the people most likely to engage. This keeps your engagement rates high and signals to inbox providers that your emails are wanted.
Cleaning your list regularly is one of the easiest ways to boost deliverability. Remove inactive users, bounced emails, and duplicate contacts. Klaviyo allows you to create suppression lists and use engagement-based filters to streamline this process.
Pro tip: Never purchase email lists. These contacts haven't opted in and are likely to hurt your sender reputation.
Every spam complaint counts against your sender score. You can minimize complaints by making your unsubscribe link easy to find, clearly stating the purpose of each email, and using double opt-in forms.
Klaviyo also offers tools to monitor complaint rates and set alerts if thresholds are crossed. React quickly to minimize damage.
Different audiences engage at different times. Klaviyo’s Smart Send Time feature uses AI to determine when each segment is most likely to open emails. Use this to your advantage by scheduling your sends based on real-time behavior.
B2B emails might perform better during weekday mornings, while eCommerce audiences could respond more on weekends or evenings. Test, refine, and repeat.
If your open rates suddenly drop or bounce rates spike, Klaviyo makes it easy to diagnose the issue. Use their reporting dashboard to:
Re-engage dormant users with win-back campaigns or suppress them until you’ve optimized your deliverability again.
Even with the best tools at your fingertips, email deliverability is an ongoing process. That’s where expert partners come in.
