Fixing Klaviyo Email Deliverability Issues

Klaviyo has become a popular choice for email marketing, but many users find themselves frustrated by deliverability issues. You’re not alone if your emails often land in spam folders or your open rates plummet. Email deliverability is crucial for the success of your marketing campaigns, as it directly affects how many people see your messages. In this article, we’ll explore common email deliverability problems in Klaviyo and provide actionable steps to fix them. We’ll also discuss alternative solutions that could better meet your needs.

Understanding Email Deliverability

Email deliverability refers to the ability of your emails to reach the inbox of your subscribers. It’s more than just sending out a message; it’s about ensuring that message is seen by your intended audience. If your emails end up in spam folders or are bounced back, your marketing efforts can fall flat. Key terms to understand include:

• Open rates: The percentage of recipients who open your email
• Bounce rates: The percentage of emails that were not successfully delivered
• Spam complaints: The number of recipients who mark your emails as spam

High bounce rates and spam complaints can hurt your sender reputation, making it even harder for your emails to reach inboxes in the future.

Common Email Deliverability Problems in Klaviyo

Here are some common issues Klaviyo users face when it comes to email deliverability:

1. Emails Landing in Spam Folders: This can happen for various reasons, including poor sender reputation or lack of authentication
2. High Bounce Rates: Bounces can occur if you’re sending to outdated or invalid email addresses
3. Low Open Rates: If your subject lines are uninteresting or your audience is not well-segmented, recipients may not bother to open your emails

These issues can significantly hinder your marketing success and lead to frustration as you watch your carefully crafted messages go unseen.

Steps to Fix Deliverability Issues

Here are practical steps you can take to improve your email deliverability in Klaviyo:

1. Verify Your Sending Domain

One of the most critical steps is to verify your sending domain. Setting up domain authentication, including SPF (Sender Policy Framework) and DKIM Signature Alignment (DomainKeys Identified Mail), helps establish your credibility as a sender. This process tells email providers that you are who you say you are, reducing the likelihood of your emails being marked as spam.

To set up authentication in Klaviyo:

• Go to your account settings
• Navigate to the “Domains” section
• Follow the prompts to authenticate your sending domain

Note that if your domain is new, it may not be properly warmed up and this can result in deliverability issues. Refer to our guide on how to warm up your email domain for more information.

2. Clean Your Email List

Regularly cleaning your email list is vital. Keeping outdated or invalid email addresses can lead to high bounce rates, which negatively impact your sender reputation. Remove inactive subscribers and consider using email verification tools to ensure that the addresses on your list are valid.

3. Improve Email Content

Content matters! Create engaging subject lines that entice recipients to open your emails. Your content should also be relevant and valuable to your audience. Additionally, ensure your emails are mobile-friendly, as many users check their emails on their phones.

4. Monitor Engagement Metrics

Klaviyo provides various analytics tools to track your engagement metrics. Pay close attention to open rates and click-through rates. If you notice declining metrics, analyze your campaigns to identify patterns and make adjustments as needed. Consider segmenting your audience based on their interests and behaviors to send more targeted content.

Best Practices for Future Deliverability

To maintain good deliverability rates in the future, keep these best practices in mind:

• Regularly Update Your Email List: Consistently remove inactive subscribers to keep your list healthy
• Segment Your Audience: Tailor your messages to specific segments of your audience for better engagement
• Conduct A/B Testing: Experiment with different subject lines and email content to find what resonates best with your audience

Consider Alternative Solutions

If you find that Klaviyo is still not meeting your email marketing needs despite implementing these strategies, it might be time to explore alternative solutions. One option to consider is Broadcast, a self-hosted email marketing software that allows you to take control of your email campaigns.

Frequently asked questions

Why are my Klaviyo emails going to spam?

Most often it comes down to authentication and reputation. If your sending domain is missing SPF, DKIM, or DMARC — or DKIM is not aligned to your From domain — mailbox providers can’t verify you, and messages get filtered. A cold domain, a spike in volume, sending to unengaged or purchased lists, and a spam-complaint rate above ~0.1% all push you toward the spam folder too. Fix authentication first, then engagement and list hygiene.

How do I set up SPF, DKIM, and DMARC for Klaviyo?

In Klaviyo, authenticate your sending domain under account settings → Domains, which provides the DKIM (and CNAME) records to add at your DNS host. Add or update your SPF record to include Klaviyo’s sending infrastructure, and publish a DMARC record (start at p=none to monitor, then tighten to quarantine or reject once reports look clean). Our SPF record generator and DKIM alignment guide walk through the specifics.

Does Klaviyo use a shared or dedicated IP?

Most Klaviyo accounts send from shared IP pools, which means your inbox placement is partly affected by the sending behavior of other brands on the same IPs. Dedicated IPs are available at higher volumes but require consistent volume to stay warm. If you want an IP reputation that is fully yours, self-hosted Broadcast paired with Amazon SES or Postmark gives you dedicated sending infrastructure you control.

How long does it take to recover Klaviyo deliverability?

If the root cause is authentication, placement can improve within days of fixing SPF/DKIM/DMARC. Reputation damage from complaints or sending to stale lists takes longer — typically two to four weeks of consistent sending to engaged subscribers only, while you warm back up and keep complaints under 0.1%.
