BRILLANT Barcelona

No es útil, no se puede configurar nada ya que hay q estarlo actualizando la pagina, no esta claro como personalizar los correos. En fin poco practica y poco amigable

I wanted to try this app because it integrates with a lot of my other apps that I have... it sucks. You have to log in EVERY SINGLE TIME and recaptcha.. My account got deactivated randomly and haven't heard anything for a week. WTF? It's confusing to use and it takes a lot of time to create a newsletter. I'm switching back over to Seguno.

Diversion Stores

Unbelievably complicated to sign up to and log into. Once you log in it boots you back out. Not worth it


Pathetic support. Over-priced.
No way to cancel the account. I have to place a "cancellation request".
And they don't reply to the request for 5 days and charge my card.
Even after showing them the charge they have not replied.
Worst support ever!

Home Refinery

If you are using this on multiple stores, or doing any sort of switch, reinstallation, it is an absolute nightmare.
They have the most counterintuitive design and setup.
I don't trust letting them handle thousands of my email list, so would rather pay higher for a better email marketing app

IMG Home

What a waste of time and work!. Sign up forms will not show on internet explorer. Do you know how many people use explorer that won't be able to subscribe? What a big flaw. Not recommended


I wish their fee was more reasonable , they are extremely expensive. Gosh $300 for 13k list. Even my whole Shopify account cost $75 a month. Charging that much is ridiculous. Seems like for every 10 sales person they hired, they hired only 1 customer service. Its hideous to not be able reach customer service for a company their size and funding.

Banana Watch Bands

Worst email marketing app. SO many bugs, error messages, and delays. Cannot stand the frustration towards this platform.

I believed the hype! Shame on you Ezra Firestone - there is really nothing special about Klavyio! - pure marketing BS. They do however think they are very special...

I deleted your app from my Shopify store so why did you charge me again?

"Removing our app from your Shopify account does not cancel your Klaviyo account. We are a separate platform from Shopify so you must send a cancellation request to us in order to cancel the Klaviyo account".

WTF! Klavyio was downloaded through Shopify!!!
How is it possible that Shopify have allowed them this lofty station?

The last straw was when we reached out to them for the FIRST time with an elementary trigger split issue. After 6 emails we were thinking we'd entered some parallel existence - they just did not want to extend any help, both the Klavyio peeps JOSH + SEAN were really cagey and unwilling to assist us in any meaningful way - well this is what happens when you neglect a paying customer the way you did guys! I suggest you guys get retrained.

We are really disgusted by your lack of care and arrogant attitude.

Now kindly CANCEL my account.

I still have not received confirmation email to be able to use the service. I also sent details to customer service a week ago today. No word yet. I would like to try it out, but for now I giving a one star.
