Email Automation Software: 6 Platforms Compared for Canadian Small Businesses

Email automation software sends the right email when a customer does something: joins your list, abandons a cart, books an appointment or goes quiet for three months. For a Canadian small business, the shortlist usually comes down to six well-rated platforms: Mailchimp, Klaviyo, ActiveCampaign, MailerLite, Kit and Omnisend. The right one depends on how many contacts you have, whether you sell online, and how much automation you need before you pay.

This guide compares the six, explains which automations to build first, and covers what Canada’s Anti-Spam Legislation (CASL) expects from every automated message. Plan details were checked on each vendor’s own pricing page in November 2026. Free plans and limits change often, so confirm them before you move your list.

Email automation platforms at a glance

What email automation software does

Every platform here works the same way at its core. A trigger starts a sequence: someone subscribes, buys, clicks a link, reaches a date or gets a tag. The workflow then sends emails, waits, checks a condition and branches. Segmentation decides who enters, and reporting shows where people open, click and drop off.

Email marketing is the wider job of planning and sending campaigns to your list. Automation is the part that runs on its own once it is set up, so each message arrives when the customer has just done something and is paying attention.

The six platforms compared

Mailchimp: a familiar start for small lists

Mailchimp’s free plan covers up to 250 contacts and 500 sends a month, with a cap of 250 a day. Marketing automation flows are not part of the free plan; the Essentials plan includes flows of up to four steps. It integrates with Shopify and WooCommerce, and SMS is a paid add-on. It suits a business that wants a well-known editor and plans to upgrade once automations start to matter. If you already run Mailchimp, our team offers Mailchimp email marketing in Toronto.

Klaviyo: built around online store data

Klaviyo’s free plan sends 500 emails a month to 250 active profiles. Its strength is ecommerce: flows such as abandoned cart, segmentation built on purchase behaviour, A/B testing on paid plans, an SMS add-on, and integrations with Shopify and WooCommerce. Stores that want every email to use real order data usually end up here. We set up and run Klaviyo email marketing in Toronto for stores that want the flows built properly from day one.

ActiveCampaign: deep automation for service businesses

ActiveCampaign has no free plan; it offers a 14-day free trial. The Starter plan includes 1,000 contacts, 10,000 email sends a month and up to five actions per automation, with Shopify and WooCommerce integrations on every plan, more than 250 templates, tags and abandoned cart automations. Higher plans add more actions per automation and fuller segmentation. It suits clinics, consultants and B2B firms whose leads need several touches before they book.

MailerLite: real automation on a free plan

MailerLite’s free plan covers 250 subscribers and 2,500 emails a month, and it includes three active automations of up to five steps each, built in a visual workflow editor. Paid plans raise those limits sharply. It has ecommerce triggers and integrations with Shopify and WooCommerce. For an owner who wants a welcome series and a follow-up sequence running before spending anything, it is the clearest free choice of the six.

Kit (formerly ConvertKit): a large free list for creators

Kit’s free plan allows up to 10,000 subscribers, and Kit states there are no sending limits on any plan. The visual automation builder and automated sequences are paid features, while tagging, segmentation and subject line A/B tests are available free. It suits creators, coaches and course sellers who want to grow a big list first and add automation later.

Omnisend: email and SMS for ecommerce

Omnisend’s free plan sends up to 500 emails a month and reaches up to 250 contacts. It offers pre-built ecommerce workflows such as cart abandonment and welcome series, A/B split testing, SMS, and integrations with Shopify and WooCommerce. It fits online stores that want email and text messages managed in one place.

The first five automations to set up

1. Welcome series. Two or three emails after someone subscribes: who you are, what to expect and one clear next step.
2. Abandoned cart or abandoned enquiry. A reminder within a few hours, a second one the next day. For service businesses, the same idea works for a booking form someone started and left.
3. After the purchase or appointment. A thank you, care or setup instructions, and a request for feedback.
4. Re-engagement. A short sequence for contacts who have not opened in several months, ending with an easy way to stay or leave.
5. Date-based messages. Renewals, seasonal reminders, service intervals or birthdays, where they make sense for your business.

CASL rules every automated email must follow

CASL applies to commercial electronic messages sent to or from Canada, and an automated email is still a commercial message. The Canadian Radio-television and Telecommunications Commission (CRTC) enforces it. The CRTC’s CASL guidance covers the details; the core rules are these:

• Consent. You need express or implied consent before sending. Implied consent from a purchase generally lasts two years, and from an enquiry six months. Express consent lasts until the person withdraws it.
• Identification. Each message names the sender and gives a mailing address plus a phone number, email address or web address.
• Unsubscribe. Each message includes a working unsubscribe link, and requests must be processed within 10 business days.
• Proof. Keep records of how and when each person consented. Double opt-in is not required by CASL, but it makes that proof much easier.

Two practical points follow. Automations should check consent type and date before they send, especially re-engagement flows aimed at old contacts. And a purchased list is not consent, whatever the seller promises.

This is general information, not legal advice. Check the current rules for your situation.

How to choose the right platform

• Count your contacts honestly. Free plans are capped by contacts or sends; know where you will be in a year.
• Start from your store or booking system. If you sell on Shopify or WooCommerce, test the integration and the abandoned cart trigger before anything else.
• Decide whether you need SMS. Some platforms include it, others sell it as an add-on.
• Check what the free plan really automates. Some free plans include workflows and others hold them for paid tiers, as the table shows.
• Think about who will run it. A simple tool someone uses every week beats a powerful one nobody opens.
• Confirm consent fields. You should be able to store consent type, date and source for every contact.

Common mistakes with email automation

• Building ten workflows before the welcome series works well.
• Importing old contacts without checking whether their implied consent has expired.
• Letting automated emails drift from the brand and the offers on the website.
• Sending from a domain without proper authentication, which pushes messages to spam. Our email deliverability audit finds those problems.
• Never reviewing a flow after launch. Open and click rates tell you which step to rewrite.

Bottom line

For a small list and no budget, MailerLite is the clearest way to run automations free. Online stores lean toward Klaviyo or Omnisend, service businesses with longer sales cycles toward ActiveCampaign, creators toward Kit, and owners who want a familiar start toward Mailchimp. Whichever you pick, build the welcome series first and keep your consent records clean. When you would rather have the strategy, copy and workflows handled for you, our email marketing team in Toronto can take it from there.

Frequently asked questions

What is email automation software?

Email automation software sends emails automatically when a contact does something, such as subscribing, buying, abandoning a cart or reaching a date. You build the workflow once, and the platform sends each message at the right moment and reports on opens, clicks and sales.

Which email automation software has a free plan?

As of November 2026, Mailchimp, Klaviyo, MailerLite, Kit and Omnisend have free plans, each with limits on contacts or sends. MailerLite's free plan includes three active automations; Mailchimp's and Kit's free plans do not include automated flows. ActiveCampaign offers a 14-day free trial instead.

What is the difference between email marketing and email automation?

Email marketing covers every email you send to your list, including one-off newsletters and promotions. Email automation is the part that sends itself in response to a trigger, such as a welcome series or an abandoned cart reminder. Most platforms do both.

Which email platforms work with Shopify and WooCommerce?

All six platforms in this guide list integrations with Shopify and WooCommerce. Klaviyo and Omnisend are built around online store data, with flows such as abandoned cart based on real orders. We set up Klaviyo email marketing for stores that want those flows built properly.

Does CASL apply to automated emails?

Yes. An automated email that promotes your business is a commercial electronic message under Canada's Anti-Spam Legislation. It needs consent, must identify the sender with contact details, and must include a working unsubscribe link, with requests processed within 10 business days.

Do I need double opt-in in Canada?

CASL does not require double opt-in, but you must be able to prove consent. Double opt-in creates a clear record of when and how each person agreed, so many Canadian businesses use it for that reason.

How long does implied consent last under CASL?

Implied consent from a purchase or contract generally lasts two years, and implied consent from an enquiry lasts six months. Express consent lasts until the person withdraws it. Automations aimed at older contacts should check the consent type and date first.

Which automated emails should a small business set up first?

Start with a welcome series, then an abandoned cart or abandoned booking reminder, a follow-up after each purchase or appointment, and a re-engagement sequence for quiet contacts. Add date-based reminders once those are working.

How many contacts can I have on a free email marketing plan?

It depends on the platform. As of November 2026, Mailchimp, Klaviyo, MailerLite and Omnisend cap their free plans at 250 contacts or profiles, while Kit allows up to 10,000 subscribers. Check the vendor's current pricing page before you plan around a limit.

Is email automation worth it for a small business?

For most businesses with a list and repeat customers, yes. A welcome series and a follow-up after purchase run every day without extra work, and they reach people at the moment they are most interested. Our email marketing team in Toronto can plan and build the flows for you.

How do I move my email list to a new platform?

Export contacts with their consent type, consent date, source and unsubscribe status, import them into the new platform with those fields intact, rebuild your automations, and authenticate your sending domain before the first send. Never import contacts who unsubscribed.
