from our Loop accounts

the #1 reason subscribers cancel isn’t price.

Across the subscription brands we run on Loop, about 23% of cancel attempts in the last 90 days were people with too much product left. So we answer it with skip and slower deliveries before any discount.

faqs.

Some questions we get often.

What does Email Kong actually do?

We help eCommerce brands grow repeat revenue. That means building out your full retention strategy - email, SMS, WhatsApp, and more - so you can convert more customers, increase LTV, and reduce reliance on paid ads.

Are you just an email agency?

Not even close. We’re a full CRM and retention partner. Email is the foundation, but we also optimize your tech stack, fix broken data flows, scale SMS, improve tracking, and design customer journeys across every touchpoint.

What makes Email Kong different from other email agencies?

We don’t do templates or “30% email revenue” vanity metrics. Every strategy is built from scratch based on your business model, goals, margins, and customer behavior. And everything is done in-house - no juniors, no outsourcing.

Who will I actually work with?

You work directly with senior strategists who have built and scaled brands - not junior account managers. From strategy to execution, we stay hands-on.

Do you only work with Klaviyo?

We're a Klaviyo-certified email marketing agency - we build everything natively in the platform, though we're no strangers to the wider CRM ecosystem when the brief calls for it.

How do I know if I’m a good fit?

If you’re a DTC brand doing over $2M/year and care about retention, LTV, and owned growth - you’re in the right place. Especially if you’re tired of generic playbooks and want a partner who actually gets under the hood.

Can you just audit what I have first?

Absolutely! Our free audit reveals exactly where your setup has gaps, and what we’d do to fix it. There’s no pressure to work together right away. You’re welcome to take the insights and run with them. When you're ready to work together, we’ll be here.
