Overview
Email & Retention Marketing for Shopify stores
Most Shopify stores are sitting on a database they barely use. Existing customers are the cheapest revenue a brand has, yet list health, segmentation, and lifecycle flows are usually the areas with the biggest untapped upside. Email and retention work compounds: better deliverability means more messages actually land, better segmentation means the right customers see the right offers, and better flows mean revenue keeps coming in after the first order.
MerchantBase works inside Klaviyo and the broader retention stack (Recharge, Smile, and similar apps). We typically start with an audit — deliverability, data quality, segmentation model, and flow coverage — then rebuild the highest-leverage flows and document everything so an internal team can operate it. Active campaigns and launch cadences are supported the same way: structure, testing, QA, and clean handover.
This lane pairs naturally with the rest of the store work we do. We understand the Shopify side of the stack — checkout, customer accounts, app integrations, and backend data — so the email program actually lines up with how the store converts and operates, rather than living in a silo.

Who this is for
This service is best for Shopify teams that want experienced support, clear priorities, and practical implementation matched to the work.
You have a growing customer list that is not segmented or used well yet
Metrics like open rate, deliverability, or repeat purchase rate need attention

You want documentation and training your team can actually run
Process
How the work usually runs
Audit the account
We review deliverability, data quality, sender reputation, segmentation, and current flow coverage. This tells us what is holding back the program before anything is rebuilt.
Rebuild the highest-leverage flows
We fix or build welcome, browse and checkout abandonment, post-purchase, winback, and sunset flows — with lifecycle-appropriate segmentation so the right customers get the right messages.
Launch, test, and hand over
We structure campaigns around your launches, QA everything, and leave the team with documentation they can operate without us.
FAQ
Common questions
Do you work directly in our Klaviyo account?
Yes. We work inside the account with proper access, make changes carefully, and document what changed so the team understands the setup.
Do we need Shopify Plus for this work?
No. Klaviyo, subscription apps, and loyalty apps work with standard Shopify stores. Plus may add options but is not required.
Do you build campaigns or only flows?
Both. The priority is usually flows first because they run continuously, then campaign structure and testing around your launches.
Can you help with deliverability?
Yes. Deliverability and list health are usually part of the audit — sender reputation, list hygiene, and sending practices that protect your domain.
