Why automated flows beat one-off campaigns

Most small businesses treat email like a megaphone: write a newsletter, send it to everyone, hope something happens. The money is in flows, automated messages triggered by what a customer just did. They reach the right person at the right moment, every time, without anyone pressing send.

The data backs this up. Klaviyo’s 2026 SMS benchmarks found that automated SMS flows make up just 7.6% of messages sent but drive 45.2% of SMS revenue. On the email side, abandoned cart flows consistently sit at the top of Klaviyo’s revenue-per-recipient rankings, and with Baymard Institute putting the average online cart abandonment rate at around 70%, there’s real money sitting in carts people meant to come back to.

For Pilos, an online store for educational products, building these flows is a big part of why email and SMS now account for 29% of attributed revenue.

The 5 flows to build first

1. Welcome series

Someone just joined your list, and their interest will never be higher. Send two or three messages over the first week: who you are, your best-sellers or most popular services, and a reason to act now, like a first-order offer or a free consultation.

2. Abandoned cart (and browse abandonment)

Triggered when someone adds to cart but doesn’t check out. Send the first reminder within an hour (a text works well here if they’ve opted in), a second the next day, and a final nudge at 48 to 72 hours. Baymard’s research shows unexpected extra costs like shipping, taxes and fees are the most common reason people leave, so answer that question in the message itself.

3. Post-purchase

Say thank you, set expectations (shipping, onboarding, what happens next) and ask for a review a week or two later. Those reviews then feed your local SEO and your ads.

4. Win-back

For customers who haven’t bought in a while (60 to 120 days, depending on how often people normally buy from you). Show them what’s new, ask what they need, and give them a reason to come back.

5. Lead follow-up for service businesses

If you sell services, your “cart” is the inquiry form. Text within minutes to confirm you got their request, then follow with an email covering what to expect, proof like reviews and results, and a link to book. The first business to reply often wins the job, which is why we set this up for GC Truck Driving School.

Email or SMS? Use both, for different jobs

Email is for depth: stories, product education, newsletters and anything people may want to read later. SMS is for urgency and convenience: cart reminders, appointment confirmations, time-sensitive offers and quick replies. Keep texts short and infrequent. Behaviour-triggered texts perform far better than mass blasts.

A simple rule: if it can wait until they check their inbox, send an email. If it can’t, and they’ve agreed to texts, send an SMS.

Stay compliant, especially in Canada

In Canada, commercial emails and texts fall under Canada’s Anti-Spam Legislation (CASL). In short:

  • Get express consent before you send. A clear, unticked checkbox at sign-up is the simplest way.
  • Say who is asking and why, and that people can unsubscribe at any time.
  • Include your business details and a working unsubscribe link in every message.
  • Don’t use an email or text to ask for consent in the first place; that request counts as a commercial message too.

Penalties for businesses can reach $10 million, so check the CRTC’s official CASL guidance for the details that apply to you. In the US, email falls under CAN-SPAM and texting rules under the TCPA are stricter still.

Measure what matters

  • Revenue per recipient for each flow, compared with your regular campaigns.
  • Click and order rates, to see which messages actually move people.
  • Unsubscribe and spam complaint rates, to know when you’re sending too much.
  • Share of revenue from email and SMS. Attribution windows can overstate this, so compare it with your overall sales trend too.

Where to start

Build the welcome series and the abandoned cart flow first. They’re quick to set up and usually the first to pay for themselves. Then add post-purchase and win-back. If you’d rather have the whole system built and running for you, book a free call and we’ll map it out together.
