Newsletters get the attention, but automated email flows usually do the heavy lifting. A flow is a series of emails triggered by something a person does: signing up, starting a checkout, buying, or going quiet. Because they arrive at exactly the right moment, they tend to perform far better than one-off campaigns.
Set them up once, improve them over time, and they keep working in the background.
1. The welcome series
Triggered by: someone joining your list, downloading a guide or creating an account.
Why it matters: this is the moment interest is highest. People expect to hear from you and are most likely to open.
What to send (three to five emails over one to two weeks):
- Deliver what you promised, immediately, and say hello. Set expectations: what you'll send and how often.
- Your story: who you are, who you help and why.
- Your most useful advice: a practical tip, guide or resource.
- Proof: a case study, testimonial or before-and-after.
- The invitation: a clear next step, such as booking a call, a first-order offer or your most popular product.
2. Enquiry follow-up
Triggered by: a contact form, quote request or booked call.
What to send:
- An instant confirmation that sets expectations ("You'll hear from us within one working day")
- Before a call: a reminder, what to prepare and a short case study
- After a proposal: a friendly check-in after a few days, and an answer to the most common hesitation
For service businesses, this flow alone often wins back work that would otherwise drift away.
3. Abandoned cart or checkout
Triggered by: someone adding to cart or starting checkout but not finishing.
What to send (two to three emails over a few days):
- A simple reminder with a picture of what they left, an hour or a few hours later
- Answers to common hesitations: delivery, returns, sizing, reviews
- Optionally, a small incentive, used sparingly so people don't learn to wait for it
4. Post-purchase
Triggered by: an order or a completed project.
What to send:
- Order confirmation and what happens next
- How to get the most from the product or service: care tips, setup, a short guide
- A request for a review, once they've had time to use it
- A related product or next service, when it's genuinely relevant
A good post-purchase flow turns a first-time buyer into a repeat customer, and repeat customers are far cheaper to keep than new ones are to win.
5. Win-back
Triggered by: a customer or subscriber who hasn't opened, bought or booked in a while.
What to send:
- "We miss you" with something new or useful
- A reason to return: a new collection, a seasonal service, a fresh guide
- Finally, an easy way to stay or unsubscribe. A smaller, engaged list is worth more than a large, silent one.
Writing emails that don't feel automated
- Write like a person, from a person. Use a real name in the "from" line.
- One idea per email, with one clear link or button.
- Short subject lines that say what's inside.
- Make them easy to read on a phone: short paragraphs, no huge images.
- Personalise sensibly: first name, what they bought, what they downloaded.
- Reply-to should work. Some of the best conversations start when someone hits reply.
Permission and good practice
- Only email people who have opted in, and make that clear when they sign up
- Include an easy unsubscribe link in every email
- Say who you are and how to contact you
- Follow the rules for where your customers live, such as Malaysia's PDPA or the GDPR for people in the EU and UK
Measure and improve
For each flow, track open rate, click rate, conversions and unsubscribes. Improve one thing at a time: a subject line, the timing, the offer. Small improvements to an always-on flow compound over months.
Where to start
If you have none of these, start with the welcome series and enquiry follow-up for a service business, or welcome and abandoned cart for an online shop. Most email platforms can run all five.
