Klaviyo

Email, SMS and push marketing built on a store of your own customer data

How should I verify if my email marketing revenue is actually declining?

Several users advise against relying solely on Klaviyo's internal reporting. Instead, they suggest checking Shopify's own sales reports and pulling revenue data by referring channel to determine if the issue is a broader decline in store revenue or a specific tracking problem, such as issues with checkout scripts or consent banners.

How can I manage deliverability and protect my sender reputation?

“klaviyo being expensive sucks. a lot of people stay on shopify email longer than they should \*and\* longer than they want — just don’t bet your brand identity on its builder.”

“Experienced with supplier communications, returns, refunds, chargebacks, replacements and also Klaviyo experience.”

“The interesting part is connecting those signals back to behavior in Klaviyo so the flow reacts to what the customer is actually doing, rather than treating every churn risk the same.”

“dont use ai for images and writing, use it for everything else (customizing your store, klaviyo emails, figma email design etc)”

“If you can show someone paying $150-200/month across Shopify plus Klaviyo, Gorgias, DSers is a fraction of that on your platform, the math sells itself.”

“I have been seeing Klaviyo popping up everywhere in terms of integrations, there may be something too that. However the impression I have is that it is specifically an email marketing automation platform, which sounds… limited in scope. I have actually had 1 tracker share since February though—it is a very volatile stock!”

“Invest time in learning Klaviyo. Once you understand what it can do with segments and flows, it will pay for itself 100x. Shopify email is dog shit.”

“Built for commerce, so it digs into ads, email, and inventory, then acts on it in Meta, Klaviyo, or Shopify.”

“Do klaviyo certification”

“I've been very tempted to move off Klaviyo many times because I think it's overkill for 99% of businesses and simple tends to outperform complicated 99% of the time too, but there's no point in moving unless you get access to better data and Shopify is the end stop for that.”

“I have been using Shopify emails for my flows and marketing (Klaviyo is too expensive). Does anyone know if there are plans to improve Shopify emails?”

“I check Shopify for sales, GA4 for traffic, Meta and Google Ads for spend, Klaviyo for email, then a couple of spreadsheets our team keeps for promotions and inventory.”

“standard benchmark for flows is around 10 to 15 percent of total store revenue, but keep in mind klaviyo attribution is super greedy by default. i usually tell clients we aim for 15 percent once flows are fully setup and optimized.”

“Then fill in the gaps where you find them with something like Zapier/Make or Klaviyo if you more advanced logic (e.g. abandoned cart emails for new customers vs. established ones). Most of the review platforms will handle the review requests on their end.”

“Klaviyo pushed for a deep partnership and co-marketing a few years ago then announced their own review app right after.”

“Most stores either use Klaviyo, which handles consent segmentation more granularly and has its own abandoned cart trigger or they accept the limitation and focus on building that subscriber list at checkout.”
Patient-Passage-2286 · reddit ·
“For most stores I’d keep it simple: Shopify Email/Flow can handle a lot of the basics, then use Klaviyo if you want more advanced segmentation and lifecycle flows. For WhatsApp, you’ll usually need a separate app/integration, especially for order and delivery updates.”
PPCwithYRVDynamics · reddit ·
“For basic Klaviyo flows built from scratch,set goals bottom-up first: estimate how many people will enter each flow, expected conversion rate, and expected revenue per recipient. For example, welcome, browse/cart abandonment, post-purchase, and winback should each have their own benchmark rather than one blanket revenue target.”

“Sounds like you’ve never actually used Klaviyo because our abandoned cart flow works perfectly fine even without the customer being opted in for email Marketing.”
