We compared these email marketing tools using each vendor's pricing pages, documentation and feature lists, plus verified reviews on G2, Capterra and Trustpilot.
We looked at Canadian tax (GST/HST) support for every option too. Bouncepro.io is a sponsored placement and is labelled as one.
Not every option here has run in my business, so these are researched picks, not long-term reviews.

01 Sponsored: Bouncepro.io โ CASL-focused email for Canadian businesses
Bouncepro.io is the only platform on this list built specifically for Canadian businesses.
CASL (Canada's Anti-Spam Legislation) compliance isn't an add-on. It's built into consent collection, double opt-in flows, consent timestamp logging and unsubscribe management.
Why does that matter? A CASL violation can mean fines up to $10 million.
Bouncepro.io builds consent tools into the workflow to reduce that risk, but you're still responsible for collecting valid consent.
- Built-in CASL compliance โ consent logging, double opt-in, unsubscribe management all automatic
- CAN-SPAM compliant for businesses with US subscribers too
- Drag-and-drop email builder with mobile-responsive templates
- Automated welcome sequences, drip campaigns, and follow-up flows
- Real-time open rate, click-through rate, and bounce analytics
- List segmentation and tagging for targeted campaigns
- Designed for small businesses โ no enterprise complexity
๐จ๐ฆ Why CASL compliance matters for Canadian businesses
Canada's Anti-Spam Legislation (CASL) is one of the strictest anti-spam laws in the world.
If you send commercial messages to Canadian recipients, you need express or implied consent, a working unsubscribe link and timestamped consent records.
Violations can cost businesses up to $10 million. Most US-built email tools treat CASL as an afterthought; Bouncepro.io was built for it from the start.
02 Mailchimp โ Best established all-rounder
Mailchimp is the most recognised name in email marketing, with 13 million customers and one of the largest integration ecosystems.
Its free plan (up to 250 contacts, 500 emails a month) is genuinely useful if you're just starting out.
It now goes beyond email, with landing pages, social ads and basic CRM features.
The trade-off is price. Mailchimp is no longer the cheapest at scale, and several rivals offer more automation for less.
- Free plan up to 250 contacts
- 300+ integrations including Shopify, WooCommerce
- Excellent template library
- Landing page builder included
- Strong brand recognition โ trusted by customers
- Good analytics and A/B testing
- Gets expensive quickly as list grows
- Automation weaker than ActiveCampaign
- CASL compliance requires manual setup
- Removed free plan features over time
03 Kit (ConvertKit) โ Best for creators and newsletters
Kit (formerly ConvertKit) is the go-to for bloggers, course creators, coaches and anyone building an audience-first business.
Its tagging system is the best on the market for segmenting subscribers by what they've clicked, bought or signed up for. The visual automation builder is intuitive and powerful.
Paid newsletter subscriptions are built in, so you can earn from your list directly.
Selling products instead? Mailchimp or ActiveCampaign is usually a better fit.
- Best subscriber tagging and segmentation
- Visual automation builder โ clear and intuitive
- Built-in paid newsletter subscriptions
- Free plan up to 10,000 subscribers
- Landing page builder included
- Less suited to ecommerce or product businesses
- Templates less polished than Mailchimp
- CASL compliance requires configuration
- Limited A/B testing on free plan
04 ActiveCampaign โ Best automation
ActiveCampaign leads the market in email automation depth.
You can build multi-step sequences triggered by almost any action: opens, clicks, purchases, site visits and form fills. It also includes a CRM, lead scoring and a sales pipeline.
Need onboarding sequences, abandoned-cart recovery, re-engagement or post-purchase flows? ActiveCampaign is the most powerful option at a small business price.
- Most powerful email automation in the market
- Built-in CRM and sales pipeline
- Lead scoring and contact tagging
- 800+ integrations
- SMS marketing included on higher plans
- Steeper learning curve than Mailchimp
- No free plan (14-day trial only)
- More complex than most small businesses need
- CASL compliance is manual โ not built in
05 Brevo โ Best free plan
Brevo (formerly Sendinblue) has one of the most generous free plans in email marketing: unlimited contacts and 300 emails a day (9,000 a month).
Mailchimp's free plan caps contacts; Brevo only caps daily sends. That makes it the best free pick for a large list you email now and then.
Paid plans are priced by email volume, not contacts, so they're much cheaper than Mailchimp for big lists with low send frequency.
- Unlimited contacts on free plan
- 300 emails/day free (9,000/mo)
- Pricing by email volume โ cheap for large lists
- SMS marketing built in
- Transactional email and marketing in one
- Good automation on paid plans
- Free plan limited to 300 emails/day
- Brevo branding on free plan emails
- CASL compliance not automatic
- Support can be slow on free plan
06 Klaviyo โ Best for ecommerce
Klaviyo is the top choice for ecommerce stores on Shopify or WooCommerce.
It integrates more deeply than any other tool, syncing product catalogues, purchase history, browsing behaviour and cart data to power personalised automations.
Abandoned-cart sequences, post-purchase follow-ups, win-back campaigns and product recommendation emails are all built in.
Not selling online? Then Klaviyo is overkill and too expensive.
- Deepest Shopify and WooCommerce integration
- Abandoned cart, browse abandonment, win-back flows
- Predictive analytics โ next purchase date, CLV
- SMS + email in one platform
- Free plan up to 250 contacts
- Expensive for larger lists vs competitors
- Overkill for non-ecommerce businesses
- Steep learning curve
- CASL compliance requires manual setup
07 MailerLite โ Best value paid plans
MailerLite is one of the best-value email platforms in 2026.
Its free plan allows up to 250 subscribers and 2,500 emails a month โ more generous than Mailchimp.
Paid plans add automations, landing pages, pop-up forms, a website builder and surveys, for much less than Mailchimp at the same contact count.
If you want affordable email marketing for small business without Mailchimp prices, MailerLite is an excellent choice.
- Free plan: 250 subscribers, 2,500 emails/mo
- Cheaper than Mailchimp at every paid tier
- Automation, landing pages, surveys all included
- Clean, easy-to-use interface
- Excellent deliverability scores
- Smaller integration ecosystem than Mailchimp
- CASL compliance not built-in
- Some advanced features only on Advanced plan
- Support slower than premium tools

09 How to choose by business type
