Text Now, Email Later: Picking the Right Channel
When to text your customers and when to email them, plus CASL consent rules in plain language for small businesses in the GTA.

A text lands in a pocket that buzzes. An email lands in a pile that gets sorted later, maybe tonight, maybe Sunday. That difference is the whole decision. Not open rates, not engagement scores — just the question of whether the message needs to be seen in the next twenty minutes or the next three days.
Most small-business owners get this backwards. They send the long newsletter by text and split it into four ugly messages. Or they email a same-day cancellation notice and wonder why the client showed up anyway. Sort your messages by urgency first, and the channel picks itself.
What a text is actually good for
A text is an interruption. Treat it like one. Use it when the interruption is doing the customer a favour.
Appointment reminders and confirmations. The single highest-value text any service business sends. A client who gets a reminder the day before either shows up or tells you they can't, and both outcomes are better than silence. We covered the mechanics of this in The No-Show Problem Is a Reminder Problem.
Order status. "Your order is ready for pickup." "Driver is five minutes out." Nobody wants that in an inbox.
Same-day changes. You're closing early for a burst pipe. The stylist is sick. The patio is closed for rain. Time-sensitive, short, factual.
Waitlist and cancellation fills. A chair opens at 4pm today. The first person to reply gets it. This only works by text, because email replies arrive after the slot is gone.
A short, dated offer. "Wings are half price tonight until close." One sentence, one deadline, one link if any. Do this rarely. Every promotional text spends a little of the goodwill that keeps people subscribed.
What a text is bad at: length, images, anything with multiple options, anything the customer needs to save and refer to later. The moment you're writing a third sentence, ask if this should be an email with a text pointing at it.
What email is actually good for
Email is a filing cabinet the customer already trusts. It holds things.
Anything with detail. A new seasonal menu. Your holiday catering package with sizes and prices. A new service with three tiers. People need to read these twice and forward them to whoever is paying.
Anything with photos. Food, hair, a renovated space. Email renders images properly and costs you nothing per image.
Anything they'll come back to. Receipts, care instructions, a booking policy, a price list. Customers search their inbox for these. They don't scroll back through eight months of texts.
Slow-burn relationship stuff. A monthly note about what's new. A thank-you after a big job with a link to leave a review. Email is patient. It will sit there until Sunday morning and still get read.
Anything you want to test and tune. Subject lines, layouts, which offer pulls. You get room to experiment without annoying anyone.
The practical pairing: put the substance in email, and if something inside it is genuinely time-bound, send one short text that says the essential fact and links to the rest. "Holiday catering orders close Friday — full menu here." That's a text doing what texts do, handing off to email doing what email does.
The Canadian rules, in plain language
Canada's anti-spam law — CASL — covers commercial electronic messages, which includes both email and text. It is stricter than what you may have read on American marketing blogs, so be careful about advice that isn't written for here. The pieces that matter most day to day:
You need consent before you send. Express consent means the person actively agreed to receive commercial messages from you — they ticked a box that wasn't pre-ticked, wrote their number on a form that said what they were signing up for, or replied to a keyword. CASL also recognizes implied consent in certain situations, such as an existing business relationship, but implied consent is time-limited and narrower than people assume. The safe habit is to get express consent and write down how you got it.
Say who you are. Every commercial message needs to identify your business and give a way to contact you. In a text, that can be short, but it has to be there.
Every message needs a working unsubscribe. For email, an unsubscribe link. For text, a clear instruction like "Reply STOP to opt out." Opt-outs have to be honoured promptly, and "promptly" is not "after this campaign finishes." Make sure whoever sends your messages knows how to actually remove someone from the list, not just delete a reply.
Keep records. Who consented, when, and through what form or checkbox. If a complaint ever comes, your records are your defence. A spreadsheet with a date and a source is better than nothing, and most email and SMS platforms will log this for you if you collect consent through them.
Transactional messages are a different category in practice. A confirmation of an order the customer placed, or a reminder for an appointment they booked, is not the same as a promotional blast. That said, don't use "your appointment is tomorrow" as a wrapper for three lines of marketing. Once a message is selling, it is a commercial message.
One more thing, and we mean it: confirm the specifics for your situation before you run a real campaign. CASL has penalties, the details around implied consent and exemptions matter, and we build websites — we are not your lawyer. A short conversation with someone qualified, or a careful read of the CRTC's own guidance, is cheap compared to getting this wrong.
How to build the list without being annoying
The list is the asset. The channel is just plumbing.
Ask at the moment the customer is happiest with you. For a salon, that's at checkout after a service they love. For a restaurant, that's the pickup counter or the thank-you screen after an online order. For a service business, that's when the job is finished and working.
Make the ask specific about what they'll get and how often. "Want a text when we have same-day openings?" pulls better than "join our list," because it describes a benefit and implies restraint. And it gives you clean express consent for a defined purpose.
Put the signup where it costs nothing to offer: your online ordering checkout, your booking form, your contact page. If you already take orders or bookings through your own site, you're collecting phone numbers and emails anyway — the only missing piece is a clearly worded, unticked consent box next to them. Our services pages walk through how ordering, booking, and phone handling connect on a site you own, which is where a list like this naturally accumulates.
Don't buy lists. Don't import the numbers from your delivery app dashboard and treat them as subscribers. Consent belongs to the relationship it was given in.
A simple sending rhythm
Start smaller than you think you should.
- Texts: transactional whenever they help, promotional no more than once or twice a month. Send between late morning and early evening. Never at 7am, never at 11pm.
- Email: once or twice a month, on a predictable day. Same-ish time. One clear thing you want the reader to do.
- Both: one message, one purpose. If you're announcing a new menu and a hiring notice and a holiday closure, that's three messages, and probably two channels.
Then watch the only two numbers that matter: unsubscribes and replies. Unsubscribes tell you you're sending too much or the wrong thing. Replies tell you you wrote something a human wanted to respond to. Everything else is dashboard decoration.
The short version
If it expires today, text it. If it needs paragraphs, photos, or a decision, email it. Get express consent, put an opt-out in every commercial message, keep a record of who said yes and when, and check the specifics before your first campaign. Then send less than you're tempted to, and make each one worth the interruption.
