Best Time For Sending Email Marketing — Canada 2026 Guide

The question of the Best Time For Sending Email Marketing is more important than it might seem. Email timing directly affects open rates, click rates, and ultimately revenue — and the research on Canadian audiences specifically differs from the American benchmarks that most generic guides cite.

Boomy Marketing has managed email marketing for over 200 Canadian businesses. Here is what the data from Canadian campaigns actually shows about email send timing, and the broader best practices that determine whether your email programme generates revenue or gets ignored.

What Is the Best Time to Send Email Marketing in Canada?

Based on aggregate Canadian campaign data, the highest email open rates for B2B audiences occur on Tuesday and Wednesday between 9:00–11:00 AM Eastern Time. For B2C audiences, Thursday evenings between 7:00–9:00 PM ET show strong engagement, particularly for promotional emails. Sunday evenings (7:00–9:00 PM) perform well for newsletters and content-heavy emails where subscribers are in a relaxed reading mode.

These are starting benchmarks. Your audience's specific behaviour should be validated through A/B testing your own list. Segment-level timing differences can vary by 15–30% from population averages.

How Does Email Send Frequency Affect Performance?

For most Canadian B2B companies, 2–4 emails per month maintains list health while keeping the brand top-of-mind. For B2C e-commerce, 4–8 emails per month is sustainable for engaged subscribers, with additional transactional and triggered emails on top. Sending more than 2 emails per week to a cold list significantly increases unsubscribe rates and spam complaints, which degrades your sender reputation over time.

What Are the Email Marketing Best Practices for 2026?

The top email marketing best practices in 2026 include: personalised subject lines using first name and behavioural data (not just "Hi [FirstName]"), mobile-first email design (over 60% of Canadian emails are opened on mobile), plain-text alternatives for deliverability, AMP for email for interactive elements, preference centres to reduce unsubscribes, and sunset flows to automatically remove non-engaged subscribers before they hurt your sender score.

How Do You Measure Email Marketing Success?

The metrics that actually matter: open rate (target 25–45% for B2B, 20–35% for B2C), click-to-open rate (target 15–25%), list growth rate (net new subscribers minus unsubscribes), revenue per email sent (for e-commerce), and deliverability rate (maintain above 98%). Avoid benchmarking against industry averages that include spam-heavy senders — benchmark against your own historical performance.

Does CASL Affect Email Marketing Best Practices for Canadian Businesses?

Significantly. Canada's Anti-Spam Legislation (CASL) requires express or implied consent before sending commercial emails, a functional unsubscribe mechanism in every message, and identification of the sender in every email. CASL penalties can reach CAD $10 million for organisations. All Boomy Marketing email programs are built with CASL compliance as a foundation — not an afterthought.
