DISTILLING DECADES OF EXPERIENCE
We’ve been refining the art of retention marketing for years. Here’s what we’ve learnt.
As regular hosts and guests at conferences, online events, on-demand webinars and podcasts, we’re passionate about sharing what’s working when it comes to retention and lifecycle marketing for eCommerce brands.
Frequently asked questions
We are here to answer your questions so you can make an informed decision.
At that scale, email programs have complexity that generalist agencies can’t handle — multi-segment audiences, high SKU counts, international sending, and aggressive growth targets. Chronos assigns 6+ dedicated specialists per account (strategist, copywriter, designer, developer, QA, account manager) with lifecycle expertise built across 500+ ecommerce engagements. Brands like The Oodie, Organifi, and Fenix chose Chronos because they needed a team that could match the pace and complexity of their operations
An email marketing team sends emails. A lifecycle marketing agency designs the system that determines what gets sent, to whom, when, and why — across email, SMS, and push. At $10M+ in revenue, the difference between “more emails” and “smarter lifecycle orchestration” is the difference between 15% email revenue share and 30%+. When Chronos rebuilt lifecycle flows for Fenix, owned-channel revenue scaled from 23% to 71%. That outcome comes from systems thinking, not campaign volume.
We work in 24-week sprints. The first 4 weeks are dedicated to strategy (brand voice, creative, etc.) In weeks 4-5 we focus on email flows, and then move on to campaigns for the remaining weeks of the sprint.
The most common issues we find during audits: flows that haven’t been updated in 6+ months, suppression lists that are too aggressive or not aggressive enough, zero post-purchase logic beyond a single thank-you email, and campaign strategies driven by calendar dates rather than customer behavior. When we audited Stopwatt’s program, fixing deliverability and engagement-based targeting alone unlocked campaign performance that had been suppressed for months.
We work in 24-week sprints. The first 4 weeks cover strategy and onboarding — brand voice, creative direction, full store and flow audit, domain health checks, and technical setup. Build work begins during onboarding, with the first campaigns or rebuilt flows typically going live by the end of week 4. From there, optimization and campaign execution run in parallel. Nuve generated $6,258 from zero email history in its first month. Ecotraveller scaled from 12% to 40% email revenue share in under 60 days. The speed depends on your starting point, but material improvement typically shows within the first sprint.
We’re not the right fit for brands looking for someone to “just send more emails,” brands without enough traffic or order volume to support meaningful segmentation, or brands that want a set-it-and-forget-it relationship. We work best with ecommerce brands doing $100K+/month that treat email as a strategic growth channel. If that’s you, we’ll move fast. If it’s not yet, we’ll tell you.
Both. Our core is ecommerce, but we work with B2B brands that have the same fundamental need — turning leads and customers into recurring revenue through lifecycle marketing. The strategy differs (longer sales cycles, nurture sequences, lead scoring integration), but the discipline is the same: build a system that moves people through defined stages with the right message at the right time. If you’re a B2B brand doing $10M+ and your email program is underperforming relative to your pipeline, we should talk.
We don’t optimize for open rates or email-attributed revenue in isolation. We measure incremental revenue — the revenue your email program generates that wouldn’t have happened otherwise. That means tracking repeat purchase rate, customer lifetime value, owned-channel revenue share, and flow-to-campaign revenue ratio. When we say TheraICE saw 153% higher customer retention, that’s a business outcome, not a vanity metric.
Klaviyo’s partner tiers (Partner, Elite, Master Elite) reflect volume of accounts managed, revenue generated, and technical certification depth. Master Elite agencies get priority support from Klaviyo’s product and engineering teams, early access to beta features, and dedicated technical resources. If your email program runs on Klaviyo and generates meaningful revenue, the gap between a Partner-tier agency and a Master Elite agency shows up in implementation speed, troubleshooting capability, and access to advanced features before they’re publicly available.
When your email program is too complex for one or two in-house people to manage strategically — typically around $100K+/month in revenue. At that point, the opportunity cost of under-optimized flows, untested segmentation, and reactive campaign planning usually exceeds the cost of a dedicated agency team with lifecycle expertise across hundreds of ecommerce accounts
Klaviyo Master Elite is the highest partner tier Klaviyo awards. Fewer than [X — confirm global count with your partner manager] agencies worldwide hold it. It means priority access to Klaviyo’s product team, beta features, and dedicated technical support. Chronos has managed Klaviyo accounts generating over $400M in email-attributable revenue across 500+ ecommerce brands.
Retention marketing uses email, SMS, and push to turn first-time buyers into repeat customers. It includes post-purchase flows, win-back sequences, loyalty programs, and lifecycle segmentation. For Chronos clients, retention marketing typically drives 30–50% of total store revenue at significantly higher margins than acquisition channels.
Email marketing is one channel. Lifecycle marketing is the strategy layer that orchestrates email, SMS, push, and other owned channels around customer behavior stages — from welcome through post-purchase, replenishment, win-back, and VIP. Chronos is a lifecycle marketing agency. Email and SMS are execution channels within that system.
Chronos works across 12+ platforms including Klaviyo (Master Elite Partner), Attentive, Yotpo, Postscript, Omnisend, HubSpot, ActiveCampaign, Braze, Mailchimp, Dotdigital, and Brevo. Most ecommerce clients are on Klaviyo — we also handle migrations from other platforms.
Standard campaign turnaround is 5–7 working days, covering strategy, copy, design, and QA. For time-sensitive launches or promotions, we can compress that timeline. Every campaign goes through a dedicated QA process before send, so faster doesn’t mean less rigorous — it means the team reprioritizes.
