Sports Nutrition By Max Muscle

The absolute worst customer service of any app that I used on my online store. Will not respond to your questions and when the do respond, after days gone by, they respond with a useless link to a topic that was never your question or concern in the first place.

grand câlin

mauvaise application, ça bloque et n'envoie pas e-mail de confirmation plusieurs tentatives et mail mais rien qui bouge..............


The software itself does its job well. But it's very disturbing that once you subscribe, you cannot finish the paid subscription. Klavio demands you to contact them by e-mail, but even then they keep stalling and giving empty promises for days that "someone from the team responsible for it will contact you shortly" which obviously doesn't happen.

Extremely shady

Go Genie

Not a good experience for me. Found the app quite hard to use. Tried to implement a "don't leave" pop up on my store offering discount, it didn't work, as I tested it myself and didn't receive the discount email. Asked for help and got one response first time which didn't solve the problem, and since then Ive emailed 3 times and had no response so Im going to delete the app and try another one.

The support team need to be more responsive considering the app isn't the easiest to use.


if there is an app that makes you want to break your laptop then this would be it, go ahead break it.

Rhythm Infused Seltzers

No support. No contact synching. Wouldn't let me send my first email at the very last minute after spending a ton of time setting it up due to some account issue that they wouldn't elaborate on. Nothing but frustration. Moving to Privy. Don't bother with these guys.

Bad Customer support - Buggy App - Wasted $200 on this - Zero revenue - No way to know how to set up the app

Designcase shop

Customer support doesn't even exist i think . applied more than i don't how many times . also there free plan doesn't give any option its just not worth at all


If you want to waste your time with terrible customer service by all means sign up. I have had Klavio for 2 weeks. I have asked support one question 3 times and have yet to get a answer. I would never recommend this app to anyone!

Go Schwifty!

The trashiest app out there. Download Omnisend or Abandonment Protector. ABSOLUTELY NO CUSTOMER SUPPORT. I mean ZERO SUPPORT. After some time, the app even stopped opening and showed an error upon clicking it, I tried to reinstall it but the error persisted. Just sucks guys. Don't waste your time, there are way better apps out there with amazing customer support like Omnisend.
