Instant Avis 

Disappointment at all levels. Go for the competition, do not sign with these clowns.

Their product is buggy and the UX is so bad. Like it's been designed by AI.
I find really hard to navigate and find what I'm looking for. It was supposed to improve my productivity, instead it's done the opposite.
The only thing it's been doing consistently and effectively is messing up my campaigns. The AI behind it is so dumb and it continuously gets errors almost every time I'm trying to create campaigns or update my flows.
Needless to say, terminating Instant was the best decision we've made and we've decided to stick with Klaviyo.

Also, it turns out all the shiny use cases on their marketing website are actually false, they aren't even Instant customers...

Trust: 0%
Recommend: NO

Avoid this company.

I followed every onboarding step exactly as instructed, including uninstalling my existing email apps Klaviyo. For three days, there was zero activity. No emails, no engagement, nothing. Thinking the issue was because I was on the free trial, I upgraded and paid $99.

Nothing changed. There is no support chat anywhere on their dashboard.

Since my email marketing had essentially stopped, I immediately contacted support and asked for a refund because the product wasn't working for my store. Instead of helping troubleshoot or taking any responsibility, they sent a cold, dismissive reply saying they would cancel my subscription but would not refund the $99.

It's one thing if a product doesn't work. It's another when customer support refuses to stand behind it or make things right.

I completely regret signing up. Save yourself the time, money, and stress, and use a company that actually supports its customers.

DO NOT give Instant.one access to your Klaviyo account

We attempted to adopt Instant.one’s “Instant Audiences” feature, which was positioned as a way to boost our abandoned cart flows in Klaviyo by capturing more customers and improving revenue.

Unfortunately, before the technology was even launched, Instant.one made edits inside our Klaviyo account that disrupted our existing abandoned cart flows and prevented many sends from going out. This happened during one of the biggest sales periods in our company’s 25+ year history, so the revenue impact was severe. Based on the timing and missed sends, this cost our business tens of thousands of dollars in just a few days.

From what we could tell, Instant.one cloned our existing flows, updated filters, and created additional abandonment flows intended to capture traffic that no longer qualified under the original filters. In theory, the traffic drop in our original flows should have appeared in the new cloned flows. However, it appeared those new flows were never turned on. So instead of improving performance, the setup prevented customers from receiving key abandoned cart emails during a critical revenue window.

Even if the flows had gone live the following day, making those changes the night before a major sales period still would have left money on the table, especially since we have many overnight shoppers. That does not feel like a safe or responsible implementation process.

The most concerning part is that when a meeting was postponed, no one from Instant.one went back into the account to correct the edits or ensure the flows were functioning properly. To us, that showed a level of recklessness and lack of professionalism that made us feel completely unsafe granting them access to our Klaviyo account again.

Before we even got the chance to use their technology, our company lost a significant amount of money simply by engaging with their brand. That is just about the worst possible outcome when adopting a new platform.

We ultimately chose not to move forward with Instant.one, and based on our experience, I would strongly caution other businesses: do not give them access to your Klaviyo account—it's not worth it!

I signed up on October 30 and then our Shopify store was randomly hacked on October 31. I have been dealing with so much with getting the store back and active. We did not use the Services. I then saw I have been charged for two months of services that had not been used due to the store being down one day after making purchase with this company, what I don’t know is if me connecting the store had any thing to do with the hack, but with my uncertainties and the store not even operating at the time I reached out as soon as I saw the charges on December 30. I asked for a refund because they charged on December 30 and requested that they offer a cancellation and I told them about what occurred with the store after connecting my store to their integration. No one responded for an entire month. I wrote over five emails still no response. I tried some new additional emails and finally got hold of someone at the end ofJanuary. I requested the same thing a return of the charges. I explained the website being hacked. It still took much time. I still did not get a response and then today I got a reply stating that they refunded for January only I reached out to them in December and explain my situation so I had hoped they’d be understanding being as though I came to them versus going to our legal team working on the hack or our bank for them being unresponsive. I felt like they’re response was uncivil and they held no accountability for the late response today I am still working to at least get December charge refunded because I did contact them in enough time for them to reverse the charge.

From my experience, I would not work with them again, and I don’t see where they were of much assistance for my business that we had to rebuild and reopen one month ago. They also have no reviews that I can clearly see about their service. What should have made me weary from the beginning - lesson learned.

Easy experience to purchase on Forcast earlier today. Wasn’t expecting it to be that simple
