Our clients speak for us

CartStrings is the best money we spend every month. Hands down. Email is now our strongest channel and I don't even have to think about it.

Rachel Stein

Founder, LuxeNest Home

We tried doing Klaviyo ourselves for almost a year and it was a mess — half-built flows, campaigns going out late, no real strategy behind any of it. Meilech came in, took it completely off our plate, and now everything just runs. Wish we'd done this from day one.

David Park

Head of Marketing, ThreadCraft Apparel

I was skeptical about hiring another email agency after getting burned twice. Meilech's audit in the first week completely changed my mind — he caught things no one else even looked at. We've been with CartStrings since and I'm not going anywhere.

Sarah Goldberg

Co-Founder, PureGlow Skincare

Seriously can't recommend CartStrings enough. Our email performance has completely turned around since working with them.

Michael Torres

Director of Operations, Summit Outdoor Gear

What I appreciate most is that every email actually sounds like us. Other agencies we worked with would send over these generic templates that could've been for any brand. CartStrings gets our voice and our customers — it makes a huge difference.

Alyssa Brennan

Founder, Olive & Stone Jewelry

The ROI on CartStrings speaks for itself. Our abandoned cart recovery alone more than covers what we pay them.

Jordan Ellis

E-Commerce Manager, FitForm Athletics

We were way too dependent on ads and knew we needed email to be a real revenue channel, not just a newsletter. Meilech built the whole thing out for us and it's become one of the biggest drivers of our growth this year. Really solid team to work with.
