Klaviyo is a leader in the space, but I might recommend it to a colleague for its price point. There are other options that are more affordable and provide most of the tools Klaviyo offers. I also think it can be complicated to use for a new user.

I raised a ticket. It’s been four days and they won’t reply. So I raised another ticket asking why they are not replying. The issue was quite urgent. Then in a very short time, I saw the ticket was closed. So they have time to close my ticket, but they don’t have time or they don’t want to reply to a ticket. Very interesting.

Their attitude of doing nothing is the worst and the rudest I’ve ever seen in my years of working with several email service companies. And I see that they blame this on the pandemic. But many other good companies, they are not doing this. Your problem is your problem, don’t try to blame someone else.

So, please DO NOT buy it, consider others.

Pros
Klaviyo

  • Their flow builder is also quite intuitive and allows us to build intricate, highly targeted flows.
  • I appreciate their built-in compliance warnings & checks as they apply to opt-out methods, SMS compliance, and overall deliverability.

Cons
Klaviyo
  • Needs more visible critical notifications as we once exceeded our monthly email limit right during the Black Friday campaign. The notification was not visible enough for us to catch it on time, as a result, some emails scheduled to be sent over the weekend were never sent
  • Better library of dynamic values available for use inside emails

  • Customer service is not excellent.
  • My email list's integrity was in question. They repeatedly turned off our service questioning my results.
  • Multiple times I went to use the service in need of sending out an email and our service was not working.

Klaviyo is simply a great solution for e-com email marketing & customer relationship management:
  1. User journey visibility: We can see our clients' customers on their individual user journeys (open email, site visits) to better understand and accommodate your customers.
  2. Flow automation: Creating automated emails that follow up with new leads, those who abandoned carts, purchased.
  3. Email design: So easy to use, and more friendly than some other visual builders that we've used.
  4. Metrics visibility: We can see our clients' metrics very easily and adjust efforts accordingly.

Usability
Klaviyo
The only reason why I did not give it a 10/10 is that it cannot distinguish purchases that came through subscription recharges instead of purchases that were driven directly by email sends. Other than that, the automation qualities, design features, and segmentation options make this an incredible email platform, and I am very happy with it

Their support is always quick and we have recurring meetings with our advisor. they were great when we first started at walking us through the platform and helping us understand how to do the overall setup. They also have a wide variety of articles that cover must issues in a very clear manner that will get you out of a predicament really fast.

Alternatives Considered
Klaviyo
Klaviyo's ability to really tackle the entire marketing contact ecosystem on one platform is what really won us over. The price for everything was competitive, not necessarily the cheapest but competitive, and the ability to see that data flow from every interaction was what was crucial to us. Additionally, Klaviyo is the core of our B2C business. We were not focused on anything other than how we interact with customers directly, and Klaviyo was a direct win for us. The one negative is Klaviyo's ability to work with our B2B side of our business, because it doesn't integrate with platforms like HubSpot. That is a massive downside, but the upside justified the investment.

Mailjet was much easier to set up, and much more affordable for us than other solutions we evaluated, such as SendGrid. SendGrid may be better suited for organizations with larger volumes or more technical staff, but for us, Mailjet was a superior solution at this time. We also looked at other competitors, but Mailjet impressed us the most with their ease of use and excellent customer support.

Return on Investment
Klaviyo
  • Klaviyo brought our email channel to the top performing channel over Paid Ads several times (according to G Analytics), before Klaviyo Paid Ads were always top and the email channel struggled to even stay in 2nd place.
  • Klaviyo did cost quite a bit more than our old email platform but the ROI was much higher so it paid for itself.
  • Klaviyo implemented tools that allowed us to have a higher customer satisfaction with things like letting customers choose to receive less emails instead of unsubscribing.

  • Changing from active campaign to Mailjet decreased our mail spend by more than 50% in savings.
  • Been able to send so many emails for different campaigns increases our retention with active users who became engaged users. In our case, it is important to be in constant communication with customers.
  • Mailjet needs to be complemented with other tools, such as Zapier, in order to create better implementations. It might cost you for additional software but it is still cheaper than solutions that charge you by the number of users.
