Klaviyo

Heavy chatter around using Klaviyo alongside new AI tools and comparing it to emerging 'autonomous marketer' platforms — mostly framed positively as an ecosystem anchor.

“10 hours of work. $200 in tools. Will return $50k+ and would’ve cost $15K+ from an agency. And I did it as a favor for a friend My buddy’s wife is a nurse who wanted to start a fertility coaching business on the side. Over the past year I’ve been giving her advice here and there. She’s grown her Instagram to 12k+ followers and built it into $15-20K/month in coaching and product sales. All organic. But she was running everything off a VERY basic Shopify store. No email. No automations. No systems. Just effort. Kudos btw. That’s further than 99% of people ever would take it. She didn’t need more followers. She needed to fix the foundation so she could actually scale. Turn on paid. Build partnerships. None of that works when the infrastructure doesn’t exist. So I told her give me a day or 2 - Used Manus to redesign her Shopify. Proper CRO, product pages, upsells. Pulled her data and did competitor teardowns to structure everything. - Created a Claude project, fed it her past content, wrote 20 newsletters in her voice. Months of content done in a day. - Pulled 10 examples from top coaches and ecommerce brands, had her pick the styling she liked. Used Manus for design and our internal copywriting workflow to build every flow from scratch. - set up an agent that writes her weekly newsletters and sends to her for approval. Welcome series, abandoned cart, post-purchase, win-back. Set up Klaviyo from zero. The stack: Claude Projects, Manus, Klaviyo, Shopify. Under $200/month. Her store conversion should almost double. Should add $2-4k in new revenue from email that didn’t exist a week ago. And now every dollar she puts into growth actually compounds instead of getting wasted. $200 of tools, a little expertise and like 10 hours will add over $50k to her business this year. Growth becomes 10x easier when you fix the foundation Still blown away daily by what can be done these days. Whether the team is building a rfp bidding agent for gov contractors or I’m just helping out a friend The world has changed in an absurd way in the last 12 months”— @JamesonCamp on X

Users highlight smooth API-driven migrations and tight Shopify/Meta/GA4/Claude connections as major strengths.

“Not crypto. Just proud AF of the AI tech our team has built at @hyros_official . Like for cool points. Had a E-Com store join HYROS AIR (our new AI outbound agent) . $23,000 in extra store sales their first 5 days. PASSIVELY. They did nothing except press a few buttons. The AI did the rest. Next week if you are on Shopify if you are an EXISTING OR totally new HYROS customer you will be able to ad AIR to your site 100% free in less than 3 clicks. The AI is already completely set up based on our highest converting Shopify clients and what we've seen work. So yes...You will press 3 buttons 1. Integrate Shopify 2. Integrate Klaviyo 3. Launch And your store will make 3-5% more. Some do as much as 10-15%. You are then NOT billed anything until your making money and it usually bills to about 4-5% of the revenue it generates. You do nothing. It's risk free. It takes seconds to install. You get free money. This is the product. We are THRILLED to get it to all Shopify users next week. The AI is currently live for all currently HYROS customers in the app. (FYI this works for ALL business types, Shopify just has an effortless copy and paste integration and set up)”— @ZssBecker on X

The most loved area — flows are described as low-effort, high-return, and central to scaling revenue.

“Anthropic just shipped Claude Managed Agents 🤯 Here's how any DTC brand can deploy one in a single afternoon: Cloud-hosted, always-on agents that pull your Meta + GA4 + Shopify data, write a daily performance brief, and post it straight to Slack every morning before you're out of bed. Perfect for DTC brands and agencies who are sick of logging into 4 dashboards every morning, exporting CSVs, and trying to piece together what actually happened yesterday. Here's the 4-hour onboarding path: → Hour 1: Create your first agent via the API — model, system prompt, MCP tools (Meta, GA4, Shopify, Slack) → Hour 2: Spin up the cloud environment the agent runs inside → Hour 3: Run a test session, verify the Slack brief posts correctly, tighten the system prompt → Hour 4: Wire up a daily cron schedule, set your spend limits, walk away By 5pm you're done. By tomorrow morning, you have a brief in Slack written by an agent that knows your brand. No CSV exports. No dashboard tab hell. No "let me loop in our data person." What this builds you: → A cloud-hosted agent Anthropic runs for you, not something you babysit on your Mac → Daily performance briefs posted to Slack every morning before you sit down → Tool access to your real accounts with scoped permissions and full audit logs → A foundation to build 4 more specialist agents on top of (creative reviewer, competitor monitor, review digester, weekly exec brief) → Pricing that costs less per month than a single Klaviyo seat I put together the full onboarding playbook: the Claude Platform setup, the MCP connection steps, the system prompt for your first agent, and the spec for 4 more agents to build next. Want it for free? > Like this post > Comment "AGENTS" And I'll send it over (must be following so I can DM)”— @mikefutia on X

Praise for deliverability tooling offset by frustration with attribution mismatches versus ad platforms.

“🚨 Test Completed ➡️ Bid Cap vs Highest Volume 🚨 I completed an 80k test of Bid Cap vs Highest Volume over a 30 day period. Exact same set up, same creatives, same attribution window. I did no exclusions on purpose here to see what delivery would actually look like without any technical input. How would each deliver. Second point... I did not force Bid Cap to spend the same as Highest Volume they both actually ended up within $500 in spend of one another. I also never once adjust bids. Put them at what previous bid where I had the delivery where I wanted it. Last thing here. Nothing else ran inside this ad account. It was a separate account with just these two campaigns. They started and ended exact same day. -- Here are your results -- Bid Cap Strategy Spend: $39,707 Purchases: 464 ROAS: 1.90 CPP: $85.58 Highest Volume Strategy Spend: $40,160 Purchases: 276 ROAS: 1.10 CPP: $145.51 -- Next question -- Audience Segment Delivery -- My segments are broken out as follows. Existing Customers ↴ Shopify List, Klaviyo API All Purchases, Pixel 180 Day Purchases Engaged Audeince ↴ Klaviyo List All Non-Purchases, 180 Day WV, VC, ATC, IC, Exclude 180 Day Purchases New Audience ↴ Everyone Else (Non Website Visitors) - Here is the delivery in each campaign and the ROAS - (See Screenshot) Top = Bid Cap Bottom = Highest Volume Make your conclusions and lets here your thoughts.”— @ToriiRowe on X

Seen as core infrastructure for reorder and lifecycle strategy, though some question inflated attribution claims.

“$2.4M spent on Meta ads in 2025. $180k spent on our email flow rebuild in 2025. Guess which one generated more net profit? Not close. Founders love talking about ad accounts. Nobody talks about their Klaviyo backend. That's exactly why the money's there.”— @PascalZeMarshal on X

Strongly positive — list hygiene and targeted segments seen as key to cutting costs and boosting engagement.

“Stop wasting ad spend on people who already bought from you. Most brands are showing acquisition ads to existing customers, which kills efficiency and pisses off customers who keep seeing ads for products they already own. Here’s how to exclude them properly using 3 methods: Method 1: Meta Pixel + CAPI Data Go to Meta Ads Manager → Audiences → Create Audience → Custom Audience → Website. Select “Purchase” event and set the timeframe to 180 days. This automatically pulls everyone who completed a purchase tracked by your pixel and Conversions API. Method 2: Klaviyo Integration In Klaviyo, go to Integrations → Meta → Connect Account. Once connected, create a segment of all customers who have placed at least one order. Then go to Klaviyo → Integrations → Meta → Sync Audiences and push this segment to Meta as a custom audience. This syncs automatically and catches people who bought but might not have been tracked by pixel (iOS users, ad blockers, etc.). Method 3: Manual Upload In Shopify, go to Customers → Export → All customers → Export as CSV. In Meta Ads Manager → Audiences → Create Audience → Custom Audience → Customer List → Upload your CSV file. Map the data fields (email, phone, name, etc…) and let Meta process it. Repeat this monthly to keep it up to date. Then exclude all three audiences from your acquisition campaigns. On adset level, go to Targeting → Exclude → Custom Audiences → Select all three purchaser audiences. Why use all three methods? Because no single tracking method is 100% accurate. Pixel data misses some people, Klaviyo might not have everyone’s email, and manual uploads can get outdated. Layering all three ensures you’re not advertising the same product to people who already bought it.”— @DTCMidas on X

Generally positive on creative capabilities, especially new AI-assisted email design workflows.

“You can now design high-converting, on-brand, ready-to-send emails directly inside of Claude (‼️) So many ecom brands have been telling me the same thing recently. "We're using Claude for everything, and it knows everything about our brand, our products, our customers, our ad performance, etc." They don't want to start teaching another platform about their brand all over again. They want to use everything that Claude already knows as the foundation for strategizing and designing their emails. So we built a connector that plugs directly into your Claude account. Now inside your Claude account, you can: → Generate high-converting email campaign ideas and strategy → Generate on-brand copy → Design on-brand emails → Click one button and schedule the designed emails in Klaviyo Zero manual work. Zero excuses to not be sending at least 2-3 email campaigns per week and generating easy revenue and a high ROI on your Klaviyo bill. Comment "AUTOMATE" and I'll send over instructions on how to set up our connector in your Claude account to start automating your email marketing end-to-end.”— @elliotkovac28 on X

Most contested theme — value is acknowledged but rising costs at scale draw real pushback.

“Is Klaviyo actually overpriced? Or are you paying for a Ferrari and driving it like a scooter? Flows off. No segmentation. Sending to everyone. The price isn't the problem. The usage is.”— @Markoemailwiz on X
