Klaviyo: Email Marketing & SMS

Love the functionality of this platform! Has made it so much easier to target different sections of my list!

My store launch is being delayed because I want to ensure that the leads from paid advertisements will convert, so I need a solid email flow set up first. Unfortunately, I've encountered several issues with Klaviyo.

First, I couldn’t upload my own fonts. I followed Klaviyo's suggestion to use the inspect tool to find the font code and upload its link, but it didn’t work. Although my domain and Shopify are connected successfully, I keep receiving errors when trying to publish a flow, stating it’s not synced to my store.

I tested some cart abandonment flows using different accounts and waiting long periods, but no emails were sent, not even for test orders. When emails are sent successfully, they often end up in spam.

Additionally, I’m forced to have my address in the footer of emails, which is problematic for a home-based business. Klaviyo also places a branding watermark on every email or pop-up, requiring an upgrade to a $20 plan to remove it. While I plan to upgrade once everything works smoothly to ensure my brand looks professional, the numerous errors and lack of support make it difficult to trust Klaviyo.

I’ve spent two full business days trying to get it to work without genuine support. When someone finally responded today, they only addressed one error and didn’t provide a solution. It seems that without a higher-end plan, Klaviyo doesn’t offer much support. Larger companies receive weekly demos, but small startups are left struggling.

Edit: They say that "double opt in" is optional but even if you uncheck it, they still wont add any email to your list that doesnt confirm a double opt in. Not only that, but they don't work with any intergration that is not on klaviyo, any sign ups from pop ups from other apps wont be added to klaviyos email list unless they specifically were added by a klaviyo native pop up. How frustrating, I've had my last straw. I'm out.

Update: I've struggled installing, uninstalling, doing test emails etc for 3 days. Did they help or respond to my help requests? No. I saw a "klaviyotest" email subscribe to my list but never followed up on my request, which means they do see my requests but don't bother to help. If you're a start up, don't even waste your time here. They only care about big companeis and will kiss the ground they walk on being the one to spam those companies every two days begging them to use their platform. (a witness from both sides).
Edit: If you're a start up, turn away. Don't just listen to my personal experience, but take a look at their "pricing options page," its a giveaway of how they give a different treatment to more established companies who starting at 10000 subscribers would get a "demo," video onboarding etc, meanwhile small busineses like us can barely even get an email response.

Fantastic email platform! The customer support is second to none.

Great service and great support.

This app has been amazing - the way everything is so customisable and you can do so much with your existing subscribers list is so helpful. The online support is amazing and so fast with getting on the online chat to assist. The forums are also helpful along with the step by step guides. Cannot recommend this app more!

easy to use and has definitely helped to increase our online revenue.

Great tool to increase sales and growth! Very happy with Klaviyo

Probably the most user friendly esp there is. if you are an ecom brand owner, and not utilizing emails, consider Klaviyo. has free resources to get you started and the aftersales support is superb.

Great product that’s boosting my revenue. It mangles it a breeze and it’s the best my emails have ever looked!

I am not interested in email marketing.. i hate it to be honest.
But, Adam W was a great help to me with Klaviyo.
Thanks a ton
