Absolutely horrific experience for 4…

Reviewed on 2021-04-04T11:53:07

Absolutely horrific experience for 4 months now. Product Expert who calls himself Sakinah should be fired on the spot.Ive been charged automatically for 3 months incorrectly despite asking to be downgraded to a free plan. Nobody bothered to do that. Customer service is non existent and useless to say the least. There is no way to remove a credit card so the monthly payments will stop charging - Sakinah simply ignored the request to help. No calls/emails from management to resolve the issue. Have been promised refunds for months now in writing, to date 3 month on - this has not happened. Sakinah is rude and terrible to deal with as is the rest of the team. Still no solution to this and we have taken legal action.

Cancelation is like a quest - impossible!

Reviewed on 2020-12-15T18:41:21

My company decided to give a try to this service. Well, we've tried and decided to cancel the subscription..but guess what - it's almost impossible!!! You've submitted a ticket,then confirm it again and there is a silence... Then again and again for simple subscription cancellation. This company doesn't comply with VISA rules as well, they will rebill you without any notice.

Top-notch email service

Reviewed on 2020-12-15T00:22:52

Top-notch email service. Has just about the most integrations of any provider; allows us to centralize almost all of our email sending (we're on the BigCommerce platform).Have used for 3.5 years with consistently high deliverability rates and minimal critical bugs. Lots of features have been added and enhanced over the years.

Terrible - Campaign not send!

Reviewed on 2020-09-14T08:21:37

We migrated from Mailchimp to Klaviyo. Got all marketing ready, payed 375 usd for 15.000 subscribers and when all is ready from marketing,stock etc we launched the campaign. Just to get our account flagged and closed. And the campaign did not get shipped! And no online chat or anything to help! DO NOT USE Klaviyo for professional use! Maybe ok for hobby users, but not for professional ecommerce.
