Loop keeps its own agency directory, and every agency below is in it. The ones worth your time are the agencies that work inside your Loop admin, because the cancel screen, the save offers and the payment retries all live there, while the emails that support them live in Klaviyo.

1. Email Kong
Loop brands are the core of our work. We build the cancel flow with offers mapped to each cancel reason, set up failed payment recovery, run winback, and write and send the Klaviyo email and SMS around all of it. If you're moving to Loop from another app, we handle the migration and rebuild the Klaviyo flows that ran on your old app's events. We also restyle Loop's notification emails to match your brand.
We're a Loop agency partner and a Klaviyo Master Platinum Partner, ranked in the top 2.5% of Klaviyo partners worldwide, and a member of Klaviyo's Partner Advisory Council. Over 5 years we've worked with 140+ DTC brands and driven $59M+ in revenue attributed to Klaviyo, and we're rated 4.5 on Trustpilot.
On the brands we run, the most common cancel reason is "I have enough or too much product", at about 23% of cancel attempts over 90 days, so that's the first screen we fix. Kaori went from 3.3% to 19% of store revenue coming from Klaviyo, and Penrose Skin went from 15.2% to 23.2% while the store more than tripled. Other Loop clients include KittySpout, HolySwish and Ritual Labs.
Your first flow is live within 72 hours of us getting access. Retainers start from $5,000 a month.
Good fit if: you're on Loop, or moving to it, and want one team that owns the cancel flow, payment recovery and Klaviyo.
2. YOCTO
YOCTO is a Klaviyo Elite partner that works across Loop, Recharge and Skio for subscription brands of roughly $5M to $150M a year in health, wellness, supplements, food and drink, beauty and pet.
