Klaviyo agency in Montréal
Email and CRM for Québec e-commerce brands. In Canada, consent is governed by CASL, an anti-spam law stricter than the European regulation when it comes to getting onto a list.
CASL changes how lists are built
Canada's anti-spam legislation requires express or implied consent for every commercial electronic message. Implied consent exists, notably within an existing business relationship under two years or when a business address is published without a refusal notice, but it is limited in time and in scope. Every message must clearly identify the sender, give valid contact details and offer an unsubscribe mechanism honoured within ten business days.
Penalties reach ten million dollars for an organisation. That reorders priorities: before optimising a subject line, we verify where addresses came from and whether consent is traceable. A list imported without proof of opt-in is a liability, not an asset.
What we build in Klaviyo
The flows that carry revenue: welcome, abandoned cart, browse abandonment, post-purchase, win-back, and the sunset flow that protects deliverability. Each is written in both languages and triggered on the contact's language preference rather than on the site language at signup.
Segmentation starts from lifetime value and product line margin, not from open counts. A segment that opens often and never buys costs deliverability and returns nothing.
Deliverability and list hygiene
A bilingual Canadian list decays differently from a French one: inactive contacts accumulate faster when sends mix both languages. We put progressive cleaning, sending domain authentication and complaint rate monitoring in place before raising volume.
Order matters. Increasing frequency on an unclean list produces a short term gain followed by a deliverability drop that takes months to undo.

Common questions
Is CASL stricter than the European regulation?
On list entry, yes. CASL defines express and implied consent, their duration and their scope precisely, and carries high penalties. A practice acceptable in Europe may not be acceptable in Canada, particularly around acquired lists and cold outreach.
Can the same campaign go out in French and English?
Technically yes, but results degrade. We segment on language preference and send two separately written versions. That takes more production up front and clearly improves engagement, and therefore deliverability.
Will you take over an existing Klaviyo account?
Yes. We start with an audit of what exists: contact provenance, active flows, segments, authentication and complaint rates. The resulting plan is ordered by impact on margin, and it rarely starts by building new flows.
Have your account reviewed
A first conversation establishes what is actually blocking growth: account structure, measurement, margin, or simply not enough search volume. We say so even when the answer is that there is nothing to gain right now.
