r/Klaviyo

I build my email flows as fully custom HTML (AI design tools spit out complete HTML now and it has gotten scary good). Right now I paste the HTML into Klaviyo's HTML editor (Content > Templates > Create > HTML editor) and it works, but I feel like there might be a cleaner, faster workflow I am missing.

For anyone running custom HTML in Klaviyo:

1. Is pasting into the HTML editor still the best method, or is there a more efficient pipeline you use?

2. How do you handle edits later without the template breaking?

3. Any must-do checks so it renders well across all clients (Outlook, Gmail dark mode, iOS)

4. Do you use hybrid templates with data-klaviyo-region so you can still drag and drop blocks, or keep it pure HTML?

Trying to move fast without sacrificing render quality across devices. What is your actual setup? Appreciate any tips.

Set up CAPI a few weeks back (Shopify + a bit of custom backend for some events). Pixel's still running alongside it too. Was hoping EMQ would climb more than it has tbh. Just kind of stuck in the 5-6 range and nothing we try seems to push it past that.

Right now we're sending hashed email on most events, hashed phone only at checkout. No externalid yet since guest checkout makes it messy to have a consistent customer ID to hash.

Few things I'm genuinely unsure about:

Does adding externalid make a real dent in EMQ or is it more of a nice to have once email/phone are already going through?

Anyone noticed a real bump from adding fbp/fbc on top of hashed PII or is that more marginal than it sounds?

Is there just a natural ceiling here given how much guest checkout traffic we get (roughly 40% of orders)? Like is that an excuse and there's more to squeeze out?

Not chasing a perfect score, just trying to figure out if we're missing something obvious or if this is close to as good as it gets.

Curious what actually worked for you all. Also lemme know what you tried that didn't really move anything!

My 5 easy ones: abandoned checkout, welcome, abandoned cart, browse abandonment, and post purchase.

The last 2 I keep changing
- back in stock if you sell out
- win back if you've got repeat buyers
- replenishment for consumables

Are yours similar to mine or different?

I noticed that klaviyo is reporting different revenue than our store backend, and i went down a rabbit hole that i'm still in.

for context, klaviyo's attributed revenue for our last campaign was around 22% higher than what our commerce backend shows for orders placed in the same window. I thought it was probably attribution-window related but a 5-day window doesn't account for the 22% gap.

we've already checked the attribution window in Klaviyo (set to 5-day click + 1-day view), confirmed our commerce backend reports order-level revenue with no attribution overlay, looked for obvious duplicates in profile matching (none surfacing on our top customers), and verified the klaviyo identify call fires on every order via the server-side integration with conversion event mapping to placed-order.

We even cross-checked a single order against the klaviyo profile timeline and it shows up correctly attributed.

So for the klaviyo users here, has anyone reconciled this gap cleanly?

is it the cross-device tracking,credit going to klaviyo for orders that would've happened anyway, or something about how the attribution window double-counts touches across flows and campaigns, or something else entirely?

thank you for reading

I run a skincare brand with both Meta ads running and Klaviyo email flows active. When I add up what Klaviyo attributes and what Meta attributes the combined total is almost double my actual Shopify revenue. Both platforms are claiming the same customer. My accountant flagged this discreppancy and now I genuinely cannot trust any of my channel reports. How do people handle attribution overlap between email and paid?

Edit: Thanks for the helpful comments! I’ll look into adjusting attribution models and trying Triple Whale. We’re also testing AdMaxxer to get better multi-channel visibility. Appreciate the suggestions!

Hello, how do I set up a warm-up plan for a contact list of 840,000 contacts that has just been migrated to Klaviyo with a new dedicated IP address?

Not sure how many have been able to beta test Composer yet, but I get access starting tomorrow. Recently I gave Kicksend a shot and was quite impressed with the first round of results with minimal direction (other than providing my website)

I'm not crazy about the price and I didn't get to mess with it much before the trial ended. I'm just curious if Composer's output quality is equal or better than Kicksend's

Hey guys, my team and I have built a tool that auto-slices email designs, compresses images, adds alt text, sets up links, and exports straight to Klaviyo - cuts build time down to a couple minutes. Looking for a few people to actually try it and give us feedback, Free for a month, Drop a comment or DM if you want in.

Bonjour, comment gérez vous 13 langues différentes et 163 locales pour les flows Klaviyo ?

Merci beaucoup

i want beta users for my Klaviyo co - pilot .

its a free program . you have to pay nothing

I manage email for a handful of clients and diagnosing deliverability is the part that still takes me the longest.

It almost always comes down to sitting with the data manually — complaint rates, bounce composition, DNS records, send history — and building a picture from pieces that don't talk to each other. It works but it's slow, and the insight often comes too late (after two or three bad sends, not before the first one).

A few things I'm genuinely uncertain about and would love to hear how others handle:

- Do you tend to catch problems proactively, or almost always reactively after a bad campaign?

- How much of your diagnosis relies on what the ESP surfaces vs. tools vs. external checks like Postmaster or MXToolbox?

- If you've tried any dedicated deliverability tools (GlockApps seems to come up a lot), what's actually useful vs. noise?

Not looking to sell anything — genuinely trying to understand whether the manual-analysis approach I'm using is standard, or whether there are smarter workflows I'm missing.

Ive been digging through Klaviyo to get a better pulse on performance beyond the basic dashboard stats. Right now, the metrics i look at most closely:

• % of attributed revenue vs. total store revenue
• Click rates on flows/campaigns

We work with an email marketing agency, and it's difficult to ascertain how well email is doing. It feels like I'm missing the full picture, and it’s getting hard to justify agency spend without more granular reporting. How are you setting up custom reports to get a "real" view of email ROI? Are there specific metrics I’m ignoring that I should be tracking?

Flows generate most of the revenue in email from what I'm reading.

So I figured the best way to actually learn was to build a whole set start to finish instead of just one.

1. Welcome flow

I picked a random skincare brand and used their real products (not affiliated with them, just needed something real to work with)

Would really appreciate an honest rating.

Like what works, what you'd cut, what's missing, what you'd never actually send (be brutal I'm trying to get better at this)

I run a digital product brand and I'm currently building out all my standard email flows like welcome, abandoned checkout, and post-purchase sequences.

I want to know what the most efficient workflow is for writing high quality email copy using AI.

I'm specifically curious about which tools are actually worth it (Claude, ChatGPT, Jasper, etc.), how you prompt them to get good output fast, and whether you build from scratch each time or work from templates. I'd also love to hear if anyone has developed a solid system or SOP they actually stick to.

Not looking for generic advice. Would love to hear from people who've genuinely figured out a fast and repeatable process that doesn't produce robotic copy.

Thanks 🙏

I'm a Shopify store owner and parent of a sensory teen. Over the past year I kept running into the same thing — brands in this niche (weighted blankets, fidgets, autism/ADHD products) are barely touching Klaviyo.

We're talking: one email blast a month, no flows, abandoned carts going unrecovered, post-purchase sequences that don't exist. These brands have loyal, repeat-buying customers and zero automation to capture them.

I built FlowCap specifically for this. We set up and run Klaviyo automation for sensory/special needs Shopify brands — abandoned cart recovery, post-purchase welcome, win-back sequences — and charge 15% of attributed revenue. No setup fee, no retainer. If the flows don't perform, we don't get paid.

The niche part matters. Sensory buyers have specific purchase patterns. The messaging, timing, and tone that works for a generic DTC brand doesn't land the same here. We built the flows around that.

If anyone here is working with brands in this space and running into the same wall, happy to compare notes. Or if you're a brand owner lurking — we do a free Klaviyo audit. DM me or hit the link in my bio.

Hey guys! Im trying to add Klaviyo to my skillset.

I work in marketing and sales (mostly email campaign managment) would love some tips on how I can apply and leverage Klaviyo knowledge I gained from completing the Klaviyo academy certificates. Thank you!
