Four kinds of email genuinely earn their place for a service business: reminders tied to something the customer owns, seasonal prompts before the work is needed, follow-ups after a job, and occasional useful information. A general newsletter is the format most businesses reach for and the one least suited to work bought once every few years.
Why the newsletter is the wrong default
The instinct when someone says email marketing is a monthly newsletter with company news, a tip, and a photograph.
The trouble is that nobody subscribed to hear from your business generally. Someone had a job done and gave you their address so you could send an invoice. A monthly bulletin about how the team is getting on is not what they were expecting, and the unsubscribe rate reflects that.
It also fails on timing. Most trades and service work is bought once every few years. Emailing monthly to a list where perhaps one percent need you this quarter means ninety-nine percent of the sends are noise, and noise trains people to ignore you before the useful message arrives.
The four that work
Reminders tied to something they own
The strongest by a distance, because it arrives when it is relevant and it is obviously useful rather than promotional. A furnace serviced two years ago. A roof inspected in 2023. Gutters cleaned last autumn.
"We installed this in March 2023 and it is due for a service" is a message people thank you for. It also has a natural cadence built in, so you are not inventing reasons to write.
Seasonal prompts, sent early
Before the season rather than during it. People decide weeks ahead of when they call, so a message that lands as demand peaks arrives after the decision was made.
Two or three a year, tied to your actual demand pattern, is enough. This is also the one place where a message to your whole list makes sense, because seasonality applies to everyone.
Follow-up after a job
A short message a week or two after completion: confirming everything is working, saying what to watch for, and asking for a review. It is the moment goodwill is highest and it is where most review requests should live.
Genuinely useful information, occasionally
Something that helps whether or not they hire you: what to check before winter, what a permit actually involves, how to tell whether something needs repair or replacement. Infrequent, and it is what keeps a list warm between the messages that ask for something.
What not to send
- Company news. New vehicle, new hire, an anniversary. Interesting internally and to nobody else.
- Anything monthly by obligation. Frequency decided by a calendar rather than by having something to say produces filler, and filler is what gets you unsubscribed before the useful message.
- Discount announcements to everyone. They train the list to wait for the next one, and they reach mostly people who do not need the work.
- Anything bought. A purchased list is not a list, and in Canada sending to it without consent is a separate problem entirely.
The consent point
Canadian rules on commercial email are stricter than many businesses assume, and the important part is that consent generally has to exist before the first message rather than being implied by an unsubscribe link.
An existing customer relationship gives you a basis for a period after the work, which covers most of what is described above. A list of addresses collected from enquiries that never became jobs, or scraped from anywhere, does not.
Practically: keep a record of where each address came from and when, include your business details and a working unsubscribe in every message, and act on unsubscribes immediately. That is most of the compliance burden for a small business, and it is worth confirming the specifics for your own situation rather than assuming.
How often
Far less than you think. For a service business, four to eight messages a year across all four types is a reasonable target.
That sounds thin next to the usual advice and it suits how the work is actually bought. A list that hears from you three times a year with something relevant will open those messages. A list that hears from you monthly will not open any of them.
What you need before starting
- A record of who had what work done and when, which is what makes reminders possible and is the single most valuable thing on this list.
- Addresses collected properly, with a note of where each came from.
- A tool that handles unsubscribes, since doing this from your own mailbox does not scale and does not manage consent.
- Your details in the footer, business name and a physical address, which is a requirement rather than a courtesy.
Most small businesses already hold the first item in an invoicing system and have never used it for anything except invoicing. That record is the difference between email that produces work and email that produces unsubscribes.
Frequently asked questions
What should a small business email to customers?
Reminders tied to work they had done, seasonal prompts sent before the season, follow-ups after a job, and occasional genuinely useful information. Those four cover almost everything worth sending.
Should I send a monthly newsletter?
Rarely for a service business. Work bought once every few years does not suit monthly contact, and sending on a calendar rather than when you have something to say produces filler that gets you ignored.
How often should I email my list?
Four to eight times a year across all types is reasonable for a service business. A list that hears from you occasionally with something relevant will open those messages; one that hears monthly will not.
Do I need permission to email past customers?
Canadian rules generally require consent before the first commercial message, and an existing customer relationship provides a basis for a period after the work. Keep a record of where each address came from and confirm the specifics for your situation.
What is the most valuable email a service business can send?
A reminder tied to something the customer owns, such as equipment installed on a known date. It arrives when it is relevant, it reads as useful rather than promotional, and the timing sets itself.
What do I need before starting?
A record of who had what work done and when, addresses with a note of their source, a tool that handles unsubscribes properly, and your business name and address in the footer of every message.
