"Email is dead in Thailand, everyone uses LINE." We hear it weekly, and it is half true. For broadcast chat, LINE wins. But for owned, low-cost, repeatable sales — a list you control and pay nothing to message — email still quietly beats almost everything on cost per sale.
LINE and email do different jobs
LINE is immediate and personal; it is where you close and support. Email is patient and structured; it is where you nurture, re-engage, and sell to people who are not ready today. Smart Thai businesses use both — LINE for the conversation, email for the sequence. Treat them as one digital marketing system, not rivals.
Build the list before you need it
The single biggest email mistake is starting with no list. Collect addresses at every honest opportunity: checkout, a useful download, a booking. A small list of people who chose to hear from you is worth more than a bought list of thousands, which only earns spam complaints.
The three emails that pay for everything
Welcome
sent the moment someone joins. Highest open rate you will ever get; use it to set expectations and make one helpful offer
Abandoned cart
for any store, this single automation recovers sales that were otherwise gone. Pair it with a clean e-commerce build
Win-back
a short sequence to people who went quiet. Cheap to send, often surprisingly effective
Stay out of spam
Send from your own domain, not a free address. Make unsubscribing one click. Never buy lists. These are not just etiquette — they decide whether you reach the inbox at all.
Where it fits
Email is rarely the first channel we recommend, but it is one of the cheapest to run once SEO and content are bringing people in. It turns one-time visitors into repeat buyers. If you want it built into a wider plan, see our services or get a free audit.
