Alimtalk is a channel where the body is reviewed in advance. However good your code is, nothing sends without an approved template. Alongside sender number registration, this is the thing to start first.

Informational only

The premise of Alimtalk is a message the recipient is already expecting.

Approved	Not approved
Order and payment confirmation	Sales and discount announcements
Delivery status changes	New product launches
Booking confirm / change / cancel	Event participation prompts
Verification codes	Coupon promotions
Payment failure and overdue notices	Repeat-purchase nudges
Signup and account closure notices	App install prompts

Some cases sit on the line. "The item in your cart is almost sold out" reads like a fact but functions as a purchase prompt, so it is treated as promotional.

If you want to advertise, use Brand Message or an advertising SMS instead. Dressing promotion up as an Alimtalk template gets rejected, and repeated attempts put the channel itself at risk.

Designing variables

Only the values that change become variables; everything else stays fixed in the body.

[#{var2}] Your order is confirmed.

- Order number: #{var1}
- Total: #{var3}
- Expected delivery: #{var4}

We will let you know when it ships.

• #{var1} through #{var8}, eight maximum
• Do not make the body entirely variables. A template that is just #{var1} has nothing to review and gets rejected.
• Each slot should always hold the same kind of value. #{var3} cannot be an amount in one send and an address in another.
• Fill every variable the template defines. Omit one and the recipient sees #{var4} literally.

The registration flow

1. Sendgo console → Kakao Alimtalk templates → Register
2. Choose the Kakao sender profile to attach
3. Set a template name and template code — the code is the identifier your code uses (ORDER_CONFIRM_001)
4. Pick a category that matches the real use (order, delivery, booking, …)
5. Write the body and place the variables
6. Optionally add buttons — add channel, web link, delivery tracking
7. Submit for review

The status must reach approved before sending. Calling with a template code still under review returns INVALID_TEMPLATE_CODE.

Rejected wordings and how to fix them

Rejected	Why	Fix
Buy now and get 20% off!	Promotional	Move it to Brand Message
#{var1}	Nothing to review	Rewrite with fixed wording plus variables
Hello, valued customer	Purpose unclear	State what the notification is about
Message us on KakaoTalk	Drives to an outside channel	Use the official support number or a button
#{var1}, join the event	Participation prompt = promotional	Move it to Brand Message

Editing a template in production

A body change means re-review, and editing a live template can block sending until it clears.

Version instead:

ORDER_CONFIRM_001   ← live
ORDER_CONFIRM_002   ← new wording, under review

When 002 is approved, switch the template code, watch it for a while, then retire 001. Keeping the code in configuration means the switch needs no deploy.

<?php

// Configuration, not a literal — then swapping templates needs no release.
'templateCode' => config('sendgo.templates.order_confirm'),
