The Cost of Email Marketing Software

Email marketing software is priced differently than almost any other category on this list — instead of a flat tier based on features alone, nearly every platform prices primarily by the number of contacts on your list, with features layered on top. A business with 500 contacts and a business with 50,000 contacts can be using the identical plan with wildly different monthly bills. That makes list size, not feature checklists, the first number worth knowing before you start comparing vendors.

Here's a practical breakdown of what Canadian small businesses actually pay for email marketing software in 2026.

Free Tiers: Genuinely Useful for Small Lists

Mailchimp's free tier covers up to a modest number of contacts (typically around 500) with basic templates, automation, and a single audience. For a new business building its first list, this is a real starting point, not a stripped-down trial. Klaviyo also offers a free tier for small contact counts, with a particular strength in e-commerce-specific automation like abandoned cart emails — a natural fit for retail businesses selling online.

Basic Paid Plans: $13–$35 Per Month

Once a list grows past the free threshold, Mailchimp's Essentials and Standard tiers typically run $13–$35/month depending on list size, adding A/B testing, better automation, and removed Mailchimp branding. Constant Contact's core plans sit in a similar range and are commonly used by service businesses running simple monthly newsletters. At this tier, pricing is driven far more by contact count than by feature depth — doubling your list size can double your bill even if you use the exact same features.

Mid-Tier and Automation-Heavy Plans: $50–$150+ Per Month

ActiveCampaign's plans that unlock its deeper marketing automation — behavioral triggers, lead scoring, CRM-lite functionality — typically run $50–$150+/month depending on contact count and plan tier. Klaviyo's paid tiers scale in a similar pattern, and for e-commerce businesses with meaningful order volume, contact-based pricing can climb quickly once your list is in the tens of thousands — a cost worth budgeting for as your list grows, not just at the size you're at today.

Enterprise Email Marketing: Custom, Volume-Based Pricing

Large contact lists and high-volume senders move into custom pricing territory across all major platforms, often negotiated directly based on monthly send volume, dedicated IP addresses, and deliverability support. This tier is generally not relevant for a small business but worth knowing as a ceiling if you're evaluating platforms with significant growth plans.

The Most Common Email Marketing Mistake

The most consistent mistake is paying to email a list that is substantially dead — contacts who haven't opened an email in over a year, incorrect addresses, or people who never really wanted to be on the list in the first place. Because most platforms price by contact count, an unpruned list directly inflates your bill every month while dragging down your deliverability and open rates, since inactive addresses signal to inbox providers that your emails aren't wanted. Regularly removing inactive contacts is one of the few marketing tasks that both saves money and improves results at the same time.

A second common mistake is buying a plan tier for features a business isn't actually using yet — advanced automation, detailed segmentation, predictive send-time optimization — while a smaller, cheaper plan with the same core sending capability would do the job just as well until the business is large enough to need the extras. It's worth revisiting your plan tier every six to twelve months rather than assuming the plan chosen at signup is still the right fit as your list and needs change.

Connecting Email Marketing to Your CRM and Phone System

Email marketing works best when your contact list stays current automatically rather than through manual exports and imports. Connecting your email platform to your CRM means a new lead — including one captured by an AI voice agent answering an inbound call — gets added to the right nurture sequence immediately, rather than sitting unexported for weeks while the lead goes cold.

Verify current pricing directly with any platform you evaluate based on your actual contact list size, as email marketing pricing tiers shift with list count and change periodically. Most vendors publish a pricing calculator on their website — running your real contact count through it before signing up is worth the five minutes it takes.
