Retention Control

Platforms

Four platforms, so the recommendation is honest.

An agency that only works on one platform will always recommend that platform. We work on Klaviyo, Omnisend, Brevo and Attentive, so the audit can tell you the truth about which one fits your catalogue — including when it is the one you already have.

The four

Which platform, and why.

Migration between them is part of the work, not an upsell — if the audit says the platform is wrong for your catalogue, moving is the recommendation.

  1. 01

    Klaviyo

    Built on Klaviyo. Flows on real order data, segments that refresh, and one monthly number per flow.

    Best for Shopify catalogues where the product data does the work: predictive fields, catalogue blocks and order-based segments are where Klaviyo earns its price.

  2. 02

    Omnisend

    Built on Omnisend. One automation carrying email and SMS, built on your catalogue and order history.

    Best where email and SMS should be planned together and the team wants one tool, one report and a simpler monthly bill.

    Omnisend
  3. 03

    Brevo

    Built on Brevo. Marketing and transactional mail under one domain, one design system and one report.

    Best where transactional volume is high and inconsistent branding or split sending reputation is costing you inbox placement.

    Brevo
  4. 04

    Attentive

    Built on Attentive. Consent that holds up, four moments that earn a text, and revenue reported next to email.

    Best where SMS is the primary retention channel — high repeat frequency, restock-driven demand, or an audience that genuinely prefers text.

How we choose

The audit answers it in an hour, not a sales call.

Four questions decide the platform, and none of them is which tool we prefer.

  1. 01

    How much does the catalogue matter?

    Product recommendations, replenishment timing per SKU and category-aware win-back need deep catalogue data. That is where Klaviyo earns its price.

  2. 02

    Is SMS primary or supporting?

    Primary, with waitlists and flash windows: Attentive. Supporting, inside the lifecycle: Klaviyo SMS or Omnisend keeps it in one workflow.

  3. 03

    Does transactional mail belong here?

    High transactional volume and split sending reputation point at Brevo, where marketing and transactional share one identity.

  4. 04

    What can your team maintain?

    The best platform is the one your team can still run when we are not on the call. Simpler is often correct.

Questions

Choosing a platform, answered

Which email marketing platform is best for Shopify?

For most Shopify catalogues, Klaviyo or Omnisend: Klaviyo for depth of segmentation and data, Omnisend for speed and email plus SMS in one workflow. Brevo fits brands that want marketing and transactional email together, and Attentive fits brands where SMS is the main channel. We work on all four, so the recommendation follows your store.

Can you move us from one platform to another?

Yes. Migration is part of the work, not an upsell: we move flows, segments, templates and suppression lists, warm the new sending domain before volume moves across, and keep the old platform live until the new one is sending cleanly.

Do we pay the platform or do you?

You do, directly. Klaviyo, Omnisend, Brevo and Attentive each bill the brand for the subscription and message costs, and the account stays in your name. Our monthly fee covers the work only, so nothing is marked up.
