Email automations are close to digital marketing’s only “set and forget” solution. A sequence built well once produces sales for years without further work.
In brief
- A welcome sequence is the minimum for any email list.
- An abandoned cart sequence recovers 5–15 % of abandoned purchases.
- A post-purchase sequence grows repeat orders.
- A realistic one-off cost: €800–3,500 per sequence.
The welcome series
- Message 1 (immediately) — Welcome, introduce the brand
- Message 2 (day 2) — A guide or something of value
- Message 3 (day 4): Social proof (reviews)
- Message 4 (day 7): The first offer
- Message 5 (day 10) — A reminder, last chance

Abandoned cart
- Message 1 (1 h): “Did you forget something?”
- Message 2 (24 h): “Your item is still waiting”
- Message 3 (72 h) — A discount code as an incentive
The post-purchase sequence
- Message 1: Thank you, here is what happens next
- Message 2: How to use the product
- Message 3 — Ask for a review
- Message 4 — Suggest related products
Re-activation
- One “Do we miss you?” message
- If they do not open it, remove them from the list (it improves deliverability)

Frequently asked questions
Which platform for the automations?
Klaviyo for online stores, ActiveCampaign for service businesses, Mailchimp for beginners.
How many emails per sequence?
3–5 is optimal. More than seven causes unsubscribes.
Is it worth hiring a professional?
Worth it. A well-built sequence produces 5–20× more than a poor one, and the one-off cost pays for itself quickly.
