Klaviyo: Email Marketing & SMS

Advantage: easily integrate with Shopify.
Disadvantages:
1. This app is way more expensive than other marketing automation apps.
2. The app will send the "Subscription confirmation" email instead of the emails you configured to send. If you wanna disable the "Confirmation" option, you have to upgrade. And there is no information about this which wasted tons of my time to investigate my email ...

I would like to get your contact information, I have sent you emails more than once asking my questions, but I don't seem to get any answers. This is probably the best joke I've heard this year, I've emailed you guys at least 2 times and it's taken 1-2 days for you to get back to me each time.

Theres no support for this app and it is WAY TO COMPLICATED to set up with out
a live chat of some sort. dont bother!!! youll kill your self after trying to fugure this complicated program out. Bummer

THIS APP SUCKS. I send one message to 173 contacts but it says that U used up 500 messages. It you go over the amount of messages you sign up for they'll bill you for it.

When I wanted it to work most, nothing! Sent a request for customer support and they never got back to me! I tried using it because it was recommended highly to me, but instead it's a total let down. There are better services out there! Upset customer :(

The most frustrating service!! Upgraded my acct, created my first email and sent it out. We announced to our instagram following and had over 200 dms from people who never received it. THEY HAVE ONE JOB- and they can't even send it out the email. I also tried sending it to myself multiple times and could never find it anywhere in my email.

I tried to upgrade my account to allow a list of over 2000 subscribers. They charged me $125 and did not upgrade my account at all!

I cannot sign in for weeks and wrote to support team several times. Still cannot sign in!! I have correct username and password, but their confirmation code email just doesn't arrive no matter what I do. Support is non-existent. I'm deleting this.

I was immediately banned from the application without explanation, and when I prove to them that my application respects their conditions, I mysteriously get no more answers. This is an amateur service, move on and look for other applications that will be better.

After spending days trying to get Klaviyo to work for me with very little customer support, I called it and decided to give Omnisend a try.
The only thing I'm upset about is the time I wasted with Klaviyo.
Onmisend customer service is top notch and I had everything up and running in no time.
