Every small business has a customer list somewhere: in its invoicing software, its inbox or a folder of quotes. Email marketing turns that list into sales, without paying for ads to reach people who already know you. Yet it is the channel most owners leave dormant, for lack of time or for fear of being a nuisance.
Key Takeaways
- Email is the only channel your SMB truly owns.
- A list built on consent, under CASL and Law 25, gains value over time.
- Welcome series, quote follow-up, review request: three automations are enough.
- Measure clicks and sales rather than the open rate.
Why email marketing remains the most profitable channel
On Facebook, Instagram or Google, you rent attention. You pay to be seen, and the platform sets the rules: it can change its algorithm, raise its prices or cut your reach overnight. The followers on a page are not really yours.
Your email list, on the other hand, belongs to you. You can export it, switch tools and write to your customers tomorrow morning without asking anyone’s permission. Once the list is built, the cost of a send comes down to your tool’s subscription and the time it takes to write.
Advertising mostly speaks to strangers who have to be convinced of everything. A marketing email sent to your current and former customers starts ahead, because the trust is already there. A well-targeted offer can generate sales within days, whereas a new ad campaign often takes weeks to find its footing.
Email does not replace paid acquisition: it makes it pay off. A prospect brought in by Google Ads or Meta Ads who joins your list can be reached again later, at no cost. In the model of the conversion funnel, email occupies precisely the stages SMBs neglect most: the decision and the loyalty stages.
Building your list lawfully: CASL and Law 25
Here are the broad principles, and this is not legal advice: for a specific situation, consult a legal advisor.
Consent: express or implied
Canada’s anti-spam legislation (CASL) requires the recipient’s consent before you send a commercial electronic message. Express consent is the most solid: the person has ticked a box or filled in a form that clearly states they accept your emails. A pre-ticked box is not enough.
Implied consent also exists where a business relationship is established: a purchase, a contract, an inquiry. It is limited in time, however, generally two years after a purchase and six months after an inquiry. So use every contact as an opportunity to obtain express consent, which is valid until it is withdrawn.
Identify the sender and make unsubscribing easy
Every commercial email must clearly identify the business sending it and provide valid contact details, including a mailing address. It must also offer a simple, free way to unsubscribe: a link that works in one or two clicks. The law allows a maximum of ten business days to process the request; sending tools generally apply it immediately. The penalties for non-compliance can be heavy.
What Law 25 adds in Quebec
Quebec’s Law 25 governs the collection and use of personal information in the province. For a newsletter, it imposes a few habits: explain the purposes for which you are collecting an address, ask only for the information you need, publish a privacy policy and designate a person responsible for the protection of personal information. If your tool stores data outside Quebec, which is common, the law also requires an assessment before that transfer.
These requirements also serve your strategy: a list of people who asked to hear from you is worth more than a purchased list, which is to be avoided in any case.
What to put in a newsletter: types of emails and examples
Five types of email worth knowing
- The content newsletter: tips, news, behind the scenes; it maintains the relationship between two purchases.
- The promotional email: one specific offer, one deadline, one call to action.
- The quote follow-up: a reminder sent a few days after a quote that went unanswered.
- The welcome series: two or three emails introducing the business to a new subscriber.
- The re-engagement email: a message to customers who have not bought anything in a long time, with a real reason to come back.
Three newsletter examples for Quebec SMBs
A neighbourhood hardware store. At the start of each season, a short newsletter presents three jobs to plan for, such as caulking windows in the fall, the list of supplies needed and a discount valid for one week in store. The advice justifies the open; the discount triggers the visit.
A renovation contractor. Once a month, a completed project is presented in before-and-after photos, with how long the work took, followed by an invitation to request a quote before the season’s schedule fills up. The email doubles as a portfolio and creates legitimate urgency.
A physiotherapy clinic. Every send offers one practical tip, for example stretches for desk work, reminds readers that booking is done online and suggests checking their insurance coverage before year end. No promotion: the value of the advice is enough to bring patients back.
Creating a newsletter: frequency and choosing a tool
How often should you send?
The right frequency is the one you can sustain. As a guideline, one or two newsletters a month suits most SMBs: enough to stay top of mind, not enough to wear people out. Consistency matters more than volume, and one signal never lies: if unsubscribes climb after every send, you are writing too often or not usefully enough.
Choosing a sending tool
Mailchimp, Brevo and several other platforms offer the essential functions: signup forms, templates, segmentation, automations and statistics. Many have a free plan for a small list, then a price that rises with the number of contacts. Rather than hunting for the best tool in the abstract, check how it integrates with your website, how easy it is to use, whether the interface is available in the language your team works in and where the data is hosted.
Have your sending domain authenticated as well (SPF, DKIM and DMARC): without it, some of your emails risk landing in junk, because the large mailbox providers have grown stricter.
The simple automations that pay
A one-off email campaign takes effort every time you send. An automation is set up once, then works continuously. Three scenarios cover the essentials.
The welcome series
As soon as someone subscribes, a first email thanks them, says what they will receive and presents your main offer. A few days later, a second explains what sets you apart or answers the question your customers ask most often. A subscriber is never as attentive as in the moment right after signing up.
The follow-up after a quote
Plenty of quotes go unanswered because the customer forgot or is still hesitating, not because they said no. An automatic follow-up a few days after sending, then a second a week later, recovers part of those sales. That one scenario alone can improve your cost per acquisition, since you have already paid to attract that prospect.
The review request after a purchase
A few days after a delivery or the end of a mandate, an email thanks the customer and invites them to leave a review on your Google Business Profile. Reviews feed your local visibility. Send that request to all of your customers, without offering a reward in exchange: Google’s rules forbid it.
AI speeds up the work: subject line variants, a first draft of a newsletter from your notes, segments suggested from purchase history, A/B tests. Several sending tools build these functions in, and assistants such as ChatGPT, Claude or Gemini handle the rest. Knowing your customers and deciding to hit send stay in your hands; see our post on AI for small business productivity.
Measuring an email campaign: the metrics that count
Among the many statistics in your tool, four are enough to steer by.
- The open rate, to be read with caution. Since 2021, Apple Mail Privacy Protection often loads email content in advance, which counts as an open even though nobody read anything. That inflated figure is useful for comparing your own sends, not as an absolute measure.
- The click rate: the share of recipients who click a link, a better indicator of real interest.
- The unsubscribe rate: a few departures with every send are normal. A sudden rise signals a problem of frequency, relevance or targeting.
- Attributed sales: the purchases, bookings or quote requests that follow from an email. Add UTM parameters to your links to track them in Google Analytics.
That last metric is the one a business owner actually cares about. To fold it into an overall dashboard, see our post on the marketing metrics to track in an SMB.
What we do at DVCOM
At DVCOM, we start from what our clients already have: the contacts scattered across the accounting software, the CRM or the inbox. We first check what consent each group of contacts rests on, then bring them together in a suitable tool, with compliant signup forms on the website.
We then put the basic automations in place, along with a newsletter schedule the team can realistically keep. AI helps us produce and test faster; tracking attributed sales shows what is worth continuing. Email then works alongside the Google Ads and Meta Ads campaigns instead of operating in isolation.

FAQ — Newsletters and email marketing for SMBs
What is email marketing for an SMB? It is sending messages to a list of people who have agreed to hear from you: customers, former customers and prospects. It takes the form of newsletters, promotional offers and automated emails, such as a welcome series or a follow-up after a quote. It is the only channel an SMB owns outright, without paying for every contact.
How do you create a CASL-compliant newsletter? Collect express consent through a box that is not pre-ticked, identify your business in every send with valid contact details, and offer a simple unsubscribe link that is processed promptly. In Quebec, Law 25 also requires you to explain what the information you collect will be used for. For a specific situation, consult a legal advisor.
How often should an SMB send its newsletter? As a guideline, one to two newsletters a month suits most SMBs. The deciding factor is consistency: a monthly send kept up all year beats a weekly rhythm abandoned after two months.
Is the open rate still a good metric? It has become unreliable, because Apple Mail Privacy Protection triggers automatic opens that inflate the figure. Use it to compare your own sends, and rely instead on the click rate, the unsubscribe rate and attributed sales.
