Why Klaviyo Works Well for Email Marketing
As you know, effective email marketing is all about lead nurturing, touching base at appropriate intervals, and inspiring action. If youâre wondering how Klaviyo brings these moving parts together, consider these beneficial features below.Â
Advanced Audience Segmentation
Klaviyoâs advanced audience segmentation feature works by grouping contacts based on pre-determined conditions. These include:Â
User actions (e.g., purchasing a specific product)Â
Data consent (e.g., whether a contact has agreed to receive SMS communication)
Predictive behavior (e.g., the likelihood of an email subscriber following through on an online transaction)Â
Geographic location
By segmenting subscribers, youâll have a better understanding of your clientsâ customer bases and their browsing or buying behaviors over time.Â

Automated Campaigns for Each Customer Journey Stage
Automation is the only way to streamline agency processes and save valuable time along the way. And when it comes to email marketing, itâs all about reaching the right audience at the right time.Â
Customers need information to move them to the next buying cycle stage; pushing the right content can do just that. It's all about moving these prospects down your sales funnelânot as quickly as possible, but as efficiently as possible.
âBryan Lozano, Vice President of Operations at Ad-Apt
Klaviyo has the ability to send automated emails in important, time-sensitive instances. These include:
Re-engaging a customer after theyâve abandoned their shopping cart.
Targeted product recommendations for repeat customers.
But how do you know whatâs working and what isnât? Email marketing is rarely a âset it and forget itâ strategy. It needs constant monitoring and testing to fine-tune the messaging, segmentation, and timing of each campaign.Â
6 Klaviyo Metrics Your Agency Should Track
When it comes to email marketing, itâs not about sending a newsletter and going about your day. To maximize potential, your agency must adopt a data-driven approach and monitor email marketing performance over time.Â
Here are the top six email marketing metrics to include on your clientsâ Klaviyo reports. Â
1. Clickthrough Rate (CTR)Â
Email engagement metrics are vital to measuring Klaviyo email marketing performance.Â
Great emails are a conversation. The only way to assess audience perception is by studying the reactions to your email. Clicks, shares, and replies are the "facial expressions" and "words" that a person uses to communicate. And that will tell you how well your conversation is going.
âSeth Giammanco, Principal, Strategy and Technology at Minds On Design Lab
And so, include clickthrough rate as part of your agencyâs Klaviyo data-tracking. As the metric name indicates, CTR is a percentage of how many subscribers have clicked on at least one piece of linked content (such as a video, website, or CTA).Â
By understanding what drives clicks, youâll understand what resonates with your clientsâ audiences and how to leverage that for future Klaviyo campaigns.Â
As Bryan Lozano, Vice President of Operations at Ad-Apt, puts it, âClickthrough rate is an essential metric for email marketers. It shows you how many people are interested in your content and wants to learn more about what you're offering.âÂ
Conversely, low clickthrough rates mean some tweaks may be needed to improve the chances of engagement (such as less wordy graphics or placing more prominent CTAs).Â
2. Conversion Rate
Conversion rates show how successful your emails are at actually generating sales and revenue, which is incredibly important.
âBryan Lozano, Vice President of Operations at Ad-Apt
Itâs likely that many of your Klaviyo email marketing clients have conversion goals. Whether theyâre convincing email subscribers to purchase a product or download an ebook, youâll need to know whatâs the conversion rate (i.e., how many subscribers actually follow through on an action).Â
By understanding which email marketing content led to conversions, youâll know exactly what to focus on or recommend for future campaigns.Â
If youâre noticing a low email conversion rate, this may be because:
There arenât any (or enough) CTAs or theyâre not optimally placed. To fix this, add a CTA at a strategic place (e.g., after explaining the benefits of your client's product) or sprinkle a few in between (especially for longer emails)
Email marketing content isnât compelling enough. Where appropriate, use language like âDonât miss outâ or âTake advantage of this exclusive offerâ to create a sense of urgency. Additionally, make use of visually captivating graphics and videos
Your clientâs website isnât optimized for conversion. At regular intervals, map the customer journey and determine if there are any roadblocks to conversion (e.g., the âBuy Nowâ button doesnât work)
Agency Tip: If you currently use UTM tracking on Google Analytics, consider automatically adding UTM parameters for Klaviyo. That way, youâll understand how your clientsâ email marketing efforts are directly contributing to website traffic and overall conversions.Â
3. Unsubscribe Rate
As the name implies, this metric reports on how many subscribers have opted out of receiving future email marketing correspondence. And according to Klaviyo, unsubscribe rate should be no more than 0.2%.
If youâve noticed a higher unsubscribe rate. In that case, it may be because:
Your clientâs email marketing content isnât resonating with their target audience. This may mean going back to the drawing board and creating fresh, relevant content
Emails may not be optimized for viewing (e.g., clipped images due to large resolution). To avoid this from happening, run email test campaigns to ensure proper loading times, skimmability, and overall easy viewing
Subscribers didnât grant permission for email marketing. As a best practice, explicitly ask for permission before adding email subscribersÂ
Agency Tip: Create a frequency cadence that aligns with the userâs buyer journey. For example, you may want to email more frequently when someone is on the cusp of purchasing but less frequently for top-of-the-funnel leads or leads that have grown cold.

4. Receive Rate (aka Delivery Rate)
After youâve created a fantastic Klaviyo email marketing campaign, youâll need to know whether subscribers have received it (or not).
Thatâs where receive rate comes in. This email marketing metric comes in handy to pinpoint any deliverability issues and fix them when necessary.Â
Suppose youâve noticed a considerably low received email rate for your clientâs last few Klaviyo campaigns. It may be because:Â
Thereâs a growing number of invalid email addresses on your clientâs subscriber list. In this case, use an email marketing verification service to pinpoint any invalid email addresses and nip them in the bud. That way, youâll increase receive rates and avoid compromising your clientâs sending reputation
Your clientâs domain isnât registered and is marked as spam. This can be easily fixed by authenticating their domain
Your clientâs content is being marked as spam by a high volume of subscribers. In this case, be sure youâre creating relevant content that resonates with your clientâs target audience (instead of going off on a whim)
5. Open Rate
Itâs one thing for subscribers to receive an email, but it wonât mean much if it isnât actually opened.Â
To ensure that your clientsâ Klaviyo email marketing campaigns are getting the traction they deserve, be sure to track email open rates (i.e., the percentage of subscribers that open an email).Â

Track historical trends and understand customer behavior over time. Visualize Klaviyo metrics with ease and save time with AgencyAnalyticsâitâs free for 14 days.Â
Remember that a high open rate doesnât necessarily mean a subscriber has read your clientâs email. Still, itâs an important email marketing metric to monitor as itâll provide valuable insights (once taken into context).Â
All email marketing metrics are important and can't be looked at in isolation. Any metric has to be considered against a desired outcome.Â
âJames Middleditch, Director of Digital Group MediaÂ
That being said, look out for any changes to open rates over time (as this may indicate an underlying issue). Consider that:Â
A significantly low or steadily declining open rate may mean that subject lines arenât optimized (e.g., too wordy, irrelevant to the type of content subscribers signed up for)
A high email frequency may off-put some subscribers, and they may be less inclined to open emails
You may be sending emails at the wrong time of the day or the wrong day of the week to reach the majority of your clientâs audience
Whatever the case may be, consider all angles, run A/B tests, and make the necessary adjustments to increase open rate.Â
6. Bounce Rate
Similar to receive and delivery rates, bounce rate is one of the key Klaviyo metrics that highlights any potential issues with deliverability.Â
Email bounce rate refers to the percentage of emails that werenât delivered successfully. Keep in mind that there are two types of bounce rates:
Soft Bounce: This means that email deliverability was affected by a temporary issue (e.g., a subscriberâs inbox was at capacity and unable to receive new emails)
Hard Bounce: When this happens, an email wasnât successfully delivered because of a permanent issue (such as an invalid email address). These should be removed from future mailings to improve overall deliverability.
As with all email marketing campaigns, a relatively low bounce rate isnât a cause for concern.Â
However, keep an eye out for an abnormally high bounce rate. This may lead to a compromised brand reputation and even removal from the Klaviyo platform.Â
Agency Tip: To understand your clientsâ email marketing performance in comparison to their industry peers, be sure to reference email benchmarks. That way, youâll understand campaign performance on a more macro level.Â
