So far so good, I use this app for my email marketing and so far have not failed me, I hope this continues

I got a nasty shock when these guys billed me $700 for annual fees. Not reminders or notifications. When installed the app over a year ago our mailing list was much smaller. At least send a reminder since bills are not sent via Shopify. And to top it off our emails were not being sent because something changed and our domain wasn't verified so guess what? We'd been missing out sending emails to customers. Apps are meant to make the life of small businesses easier, not make them harder. We've found better options. Now we just need wait till our annual fee runs out. Never again!

Update: After 5 days and 3 different people, I was able to solve my problem. I will be testing further before moving to a paid plan. Thx
Been a free user for 3-4 days now and I understand that I don't have access to the same features as a paid user. However, I think that I have the rights to fully test the potential of the tool. Unfortunately, as a free user support is inexistent so I'm asking myself is it worth it to move to a paid plan?!

It took a little time to get accustom to the features and navigating; HOWEVER once I did - this is GOLD!! I curate clothes - I'm supposed to be dramatic :) It has helped me increase my potential reach. The analytics and segments are easy for me to read and interpret. I look forward to a long and fruitful partnership. ~ K. LaMoura

So far i love it. it sends the emails just as I want them, and it is so easy to customize your emails. Reporting is great and user friendly. Definitely happy with the app

HANDS DOWN THE BEST E-COMMERCE CRM, AUTORESPONDER, CALL IT WHATEVER YOU LIKE...I TRIED, MAILCHIMP - DRIP (horrible) and now Klaviyo, this is not even a competition, Klaviyo stand tall, alone on top of the podium 1-2-3

Switched from Mailchimp and I'm WAY happier now. Use friendly, syncs with my Shopify account - beautiful templates. Happy happy and totally recommend.

A Klaviyo error meant we broke GDPR rules. It sent a campaign to audience that was not subscribed to marketing. Consider the implications of that before signing up to their service.

Customer service is virtually non existent. After raising this issue, which is surely one of the most important service levels of an email marketing service, I had to chase them more than once for a response. For such an important issue with such big implications for a business i was horrified that Klaviyo didn't respond as a priority.

Eventually I got a two line response; they released a fix that they were continuing to monitor and they apologized for what happened.

Because it was Klaviyo's error, because they didn't immediately respond to my report, because I had to chase the status on this issue, I believe Klaviyo does not take GDPR compliance seriously. This is unacceptable to my business and I cancelled my account.

When I cancelled my account I made an official complaint identifying why I was leaving. As another example of Klaviyo's poor customer service it's been a month and i still haven't heard back from them regarding that complaint.

I pay over $900 / month and they don't even have phone support. Constant glitches delay product launches.

I used this app to connect with my list and it does what it mean to do and more plus the coaching is to the "T". It won't let you down. I will recommend it to anyone.
