Klaviyo: Email Marketing & SMS

I’m unable to find documentation around setting a confirmation email for my subscribers, I’m very confused by their plans. I have a lot of subscribers and before importing them, It looks like I would be charged may 100s of $ per month to hold them. I wasn’t able to find documentation on these issues.
I’m getting logged out regularly of my account and keep getting Captcha anytime I want to make a change. I’m not sure how to proceed. It’s also very time consuming to always keep login in, doing the two factor authentication and then doing it all again the next time I want to see the dashboard,. It’s a very tough experience I must say. It’s a nightmare to navigate the UI, I’m unsure which menu does what and I’m confused by the offering.
The error messages are also unclear and the documentation incomplete, I was unable to progress with setting this up properly. I hope I can get help. If we can get the login issue, the billing issue and the missing documentation issue I’ll update this review. Thanks and I hope you can improve your app.

Same Problem with support. Need a filter based on tagged orders not customers. Not very helpful.

wat of money i suggest not use this app

This is less than 1 star I will never use it again
I have been designing my campaign the whole day then it sent an empty template to all my customers!!

not user or beginner friendly at all. the tutorials are very long winded and dont offer much help. I dont see how this app has the rating it does. very difficult and confusing to set up

I would highly recommend using another app. This one is horrible, I got this set up luckily under the free plan and I went to use a test email that I sent to myself and my account was disabled. I reached out to customer service to find out why and got some robotic answer.
The only thing I can think of is the fact I sent out two TEST emails to myself, which I still have yet to receive, and got disabled. What bothers me most about that is in the statement they sent me about anti-abuse is. They stated "You may receive performance alerts and warnings from us", I never received any notice, when I asked the customer service rep, if you can even call it customer service, I still have not gotten a response from 12 hours ago. I will be deleting from my store and using another app.

I decided to remove this app and move on to something else. It was not as user-friendly for me at least. I need more direct support and not through email. I have a problem with companies that do not offer phone support. Email support is the most inefficient use of time and some of us simply need more guidance with a human over the phone.

I'm a small business signed up to a PAID plan but cannot use Klaviyo because I simply cannot get any support at all. I've tried for weeks to get some basic onboarding assistance. Every time I manage to get a meeting booked in with someone from Klaviyo, they always cancel either at the very last minute or whilst I'm waiting for them to attend the meeting. They don't seem to cater for the Australian market (ie. all meeting times are US based) and I suspect that's why their 'support' team consistently cancel when the meeting is even close to AUS business hours (Note: I've even tried to attend in their own time zone however and still been stood up). A lot of time and money wasted so far with no result.

I used it one time and after I deleted the app, I was charged for 70USD even tough we were not using it anymore. Be careful.

I wanted to make a Christmas E-mail with a discount code for my customers. Made it like a week ago. After submitting the campaign I was prompted with a massage saying "We will personally review campaign and get in touch with you within 24h" Now its like 5 days passed and never received anything. Deleted the app and will never use it again. Just made the e-mail in google and sent it to multiple people.
