Based on what people have said
Every answer links back to the mentions it came fromHow 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.

What people are saying about Klaviyo
55% neutral“Then ask chatGPT how to delete them from Klaviyo and will advise.”
“you place the imageurl in klaviyo. you send when the draft looks right.”
“Worth asking Klaviyo in writing for the exact policy clause they're citing, that gives you something concrete to appeal against instead of a vague explanation. And for the refund, focus on the days you were locked out rather than the full two months, that's usually a stronger ask.”
“The feature set is close enough that Klaviyo’s profile-level reorder timing wasn’t worth the extra cost and constant workarounds. Omnisend’s support is considerably faster when something breaks, and the pricing remains much saner as your contact list grows.”
“Stripe, QuickBooks, Ramp, HubSpot, Help Scout, Klaviyo. One chat.”
“Revenue is heavily over attributed in Klaviyo, and % of revenue won't work. Personally have never seen this work on the email/sms side of things.”
“how do I charge on performance basis to brands using Klaviyo?”
“Whatever you do , DO NOT TRY KLAVIYO ! I signed up with them 2 months ago and the name of my company has PEPTIDES in it.”
“Klaviyo tracks average time between orders on each profile, so I can set the flow off a threshold that's specific to that person instead of a segment I built and have to keep redoing by hand. It's still a band, not exact-to-the-day, but it updates on its own.”
“How many of you joined the recently klaviyo event? Please share your experience & what klaviyo is going to update on their eco system.”
“I think the complexity of a Klaviyo account has less to do with the size of the brand and more to do with the complexity of the customer journey, buying cycle, and overall business model…and whether the right infrastructure is in place to support all of that.”
“i’ve had a habit of doing an audit on the klaviyo acct 1-2x a year since about year 1. that worked out well.”
“It’s pretty hilarious how much better Klaviyo SMS is compared to other platforms where literally all they do is SMS lol”
“Omnisend is a good klaviyo alternative, but any popular ESP would do the job honestly.”
“I agree and we are switching away from Klaviyo. It’s unbearably tedious to work with day to day.”
“I've been using klaviyo for my business for the past while, but lately every time I go to update a flow it takes like 30-45 seconds to load on every edit. Obviously, I can't get anything done with this, so I'm looking for an alternative (unless anyone has a fix for this?). Ideally I'd like to have it under 500 or 1000 subscribers is free.”
“Step 2: Set up klaviyo flow that auto sends reminders to upload videos”
“Klaviyo’s UX on mobile is one of life’s greatest atrocities.”
“You use @hubspot? @klaviyo? @googleanalytics?”
“Has anyone seen this glitch between Shopify + Klaviyo Back in Stock before? Or know which system could causing the issue?”
“A supplement brand and a fashion brand can both use Shopify, Meta and Klaviyo.”
“Klaviyo is reportedly down for some users currently. Are you one of them?”
“Here we lay out what groa° + Maybe* are building in 4 parts: 1 unified signals, 2 orbit governance state, not static thresholds , 3 interventions inside Klaviyo, 4”
“It gets frustrating to build a bunch of similar campaigns. If you need to make several campaigns from the same email template, most of the work is just changing a handful of variables. Different product, image, headline, subject line, maybe even a different segment.”
“Any ESP that syncs order data (Klaviyo's Shopify/WooCommerce integration is the common one) lets you build a segment like "has purchased X" and exclude it from that product's campaigns automatically, no manual list-scrubbing needed.”
