Do you build flows or just do campaigns?

Both, but flows come first — they generate the majority of email revenue. I build the core flows, then layer in segmentation and campaigns on top.

How long until Klaviyo shows results?

The core flows (welcome, abandoned cart, browse abandonment) typically show revenue within the first two weeks. Segmentation and winback improvements compound over 1-3 months.

Klaviyo Retention for E-commerce

Q: Can you migrate us to Klaviyo?

Yes. Migration includes list cleanup, deliverability warm-up, historical data import and rebuilding your flows in the new account.

Q: What list size do you need to work with?

There's no strict minimum — I work with stores from a few thousand subscribers to hundreds of thousands. Below ~2,000 engaged contacts, prioritization shifts toward list growth and offer structure.

Lifecycle email and SMS that turns one-time buyers into repeat customers — flows, segmentation and deliverability done properly, with revenue you can attribute.

Signs your retention is leaking revenue

One-time buyers

Most customers never order twice because there's no structured post-purchase or winback sequence.

Weak abandonment flows

Abandoned cart and browse flows are missing, single-email, or send discounts too early.

Everything to everyone

One list, one message — no RFM or behavioural segmentation, so engagement and deliverability decay.

What's included

Core flow builds

Welcome, abandoned cart, browse abandonment, post-purchase and winback — written, designed and wired to Shopify data.

RFM & behavioural segmentation

Recency, frequency and monetary tiers plus on-site behaviour, so the right message reaches the right cohort.

Campaign strategy

A send calendar that supports launches and promos without burning the list.

Deliverability & list health

Sunset flows, authentication (SPF/DKIM/DMARC) and engagement scoring to keep you out of spam.

A/B testing

Subject lines, offers, send timing and templates tested against revenue per recipient.

Revenue attribution

Clear reporting on flow vs campaign revenue so you know exactly what's working.

Where 5x retention came from

In a two-year SaaS growth engagement, behavioural analysis identified that activation within the first 48 hours predicted long-term retention. Redesigning the onboarding and lifecycle sequence multiplied retention 5x. The same principle — fix the critical window, then segment — drives Klaviyo revenue for stores.

Questions

Klaviyo or Mailchimp for Shopify?

For Shopify e-commerce, Klaviyo wins on native data sync, segmentation depth and revenue attribution. Mailchimp is fine for simple newsletters but isn't built for lifecycle revenue at scale.

Flows or campaigns?

Flows first — they generate the majority of email revenue. Once the core flows are live and optimized, segmentation and campaigns layer on top.

Can you migrate us to Klaviyo?

Yes — list cleanup, deliverability warm-up, historical import and rebuilding your flows in the new account.

How long until it works?

Welcome, abandoned cart and browse abandonment typically show revenue within two weeks. Segmentation and winback compound over one to three months.

Minimum list size?

No strict minimum — from a few thousand subscribers to hundreds of thousands. Below ~2,000 engaged contacts, priorities shift toward list growth and offer structure.
