54/100

Klaviyo is a marketing platform, mainly for ecommerce brands, that combines a customer data profile with email, SMS and other mobile messaging, automated flows, segmentation, reviews and reporting.

Verdict: Independent users in r/ecommerce and r/Emailmarketing broadly treat Klaviyo as the most capable email tool for online stores, crediting segmentation and flows built on real purchase data, and several who moved from Mailchimp say they would not go back. The main trade-off is cost and effort: users report the bill climbing fast as a list grows past a few thousand to 30k contacts, and say it takes a dedicated owner to get value from it. About half the comments in this corpus were promotional, including a cluster of near-identical posts from different accounts pitching a switch to Omnisend, plugs for smaller SMS, popup and email tools, and agency owners; those were excluded.

In their own words

I use Klaviyo and I use it across multiple niches (all B2C.) It is definitely not the cheapest option but the segmentation options are amazing and if you set up a sunset flow, you will be able to limit contact list creep. You will be surprised just how many of your 30k contacts don't actually spend regularly on your store and you can suppress those profiles, which will limit how quickly you move up the price tiers. …

klaviyo is the right call at 30k contacts with those use cases. omnisend is solid but klaviyo's shopify segmentation depth is meaningfully better once you're doing behavioral flows.

u/le_ais Klaviyo is worth it at your size if you're doing anything complex with post-purchase. The segmentation and flow logic is genuinely best in class, one thing worth building early is a stalled shipment flow, most stores don't set it up and it's one of the highest ROI automations you can run. Cuts chargebacks, friendly frauds and WISMO tickets significantly and keeps customers from going quiet when tracking sto…

honestly the biggest gap i see is no abandoned cart recovery - i had a jewelry client doing live events who launched ecom and was leaving like 40% of their revenue on the table until we added cart abandonment emails. klaviyo over mailchimp once you're ready to scale, the segmentation is way better for product-based businesses

I’ve tried a few of these too. Klaviyo is hard to beat for ecommerce, but for smaller projects I actually like MailerLite because it’s simple and affordable. At the end of the day, the “best” platform really depends on how much complexity you actually need.

Honestly- I think Klaviyo is easier lol. I use mailchimp on another site and I hate it. It could also just be that I’m more familiar with Klaviyo. Mailchimp has templates that you can use and I think you’d be able to figure it out. I would start subscribing to emails from other companies to kind of see what they’re doing and draw inspiration from those.
