Nalin sends Korean apps' transactional and advertising email by API

Nalin's models draft templates from the events your app posts, in Korean and English, propose a class for every template, informational or advertising, and forecast inbox or spam at Naver Mail, Daum and Gmail. Advertising mail is checked against the Network Act before it goes, and nothing new leaves Seoul until the template's owner approves it.

Class my templates

A breach of the advertising rules now risks a share of revenue.

Your templates: the model read all 142 and classed each one, 118 informational, 24 advertising. '(광고) Your 3,000 points expire on Sunday' waits for approval.

Coupon and points notices only tell customers what they already hold, so they are transactional mail.

KISA's March 2026 guide counts notices for coupons, mileage or points the customer was given without asking as advertising that needs explicit prior consent, and a '혜택 알림' (benefit alert) checkbox is not that consent.

Standard is ₩490,000 a month for up to a million emails

Past the first million, ₩450 per 1,000, so 2 million emails a month is ₩940,000. Dedicated is ₩1,290,000 for up to 3 million. Prices exclude 10% VAT.

Password resets and receipts class themselves by rule. For those alone, Resend's Pro sends 50,000 emails for $20 a month, or 100,000 for $35.

Nalin sends only from Seoul. Resend sends from North Virginia, Ireland, Sao Paulo and Tokyo, which suits an app whose recipients are mostly abroad.

No visual editor, segment builder or automation canvas. Templates come from your code or the model's drafts.

Have every template classed before you pay anything

We ask for a work email, your emails a month and your template count. Your account in Seoul opens the business day after you send it, with a submit-only API key and the import guide.

Templates hard-coded in services you list by hand: the slow part

No template sends from your account until its owner approves it

NHN's ad-mail endpoint enforces the label only after someone reads each template and decides it needs one.

Nalin's classifier reads each template with its event and proposes a class. Below its 90 percent confidence line, or on a mixed template, it gives its reasons instead and the template's owner decides. Advertising ones get '(광고)' at the start of the subject, your name, email, phone and address, and an opt-out in Korean and English.

The example's 3,000 points were a sign-up bonus, so that notice is advertising and reaches only recipients with a dated, current consent.

Mail from Your store: '(광고) Your 3,000 points expire on Sunday', classed as advertising, sent only to people who agreed; sender details and Unsubscribe.

'(광고)' must be shown where the subject begins.

Enforcement Decree of the Network Act, Annex 6, on emailas amended on 5 January 2021

Moving the notices back to AlimTalk is the cheap fix: ₩13 a message, against ₩18 for a text.

AlimTalk carries no advertising at all, and Kakao rejects a template over one promotional line. Nalin's model reads a message and its send time and says which channel may carry it. Your CRM marketer picks, and Nalin sends only the email.

Every date, price and link in the draft comes from the event, and one the event lacks blocks approval.

Nalin's drafting model writes the order email in Korean and English. Every draft is marked as drafted by Nalin's model, which Korea's AI Basic Act has required since January.

Your order left our warehouse this morning and should reach you on Thursday. You can follow it with your tracking link.

6% of the revenue related to the violation

The surcharge is set on the revenue tied to the breach, while a fine stops at ₩30 million per breach type.

Where that revenue is hard to compute, the ceiling is ₩2 billion. The Korea Media and Communications Commission weighs the number of violations, intent and the steps taken to prevent them.

If our mail were landing in spam, the bounce reports would show it.

A message Naver Mail files as spam does not bounce. Naver has required SPF, DKIM and DMARC on the sending domain since July 2024. Resend's nine deliverability checks are static rules that measure no inbox placement, and its domain guide lists DMARC as optional.

For the example's Sunday points email, a model forecasts each mailbox from your DNS records, the message and Nalin's own seed mailboxes.

Where spam looks at least as likely as the inbox, that mailbox's share is held until you choose. Password resets never are.

Before Sunday's send: Naver Mail, likely spam folder, your sending subdomain has no DMARC record; Daum, inbox; Gmail, inbox. Held for Naver Mail; your call.

The record your privacy officer asks for stays in Seoul while you keep the account

Resend keeps email and logs 30 days on its self-serve plans. Nalin's model drafts the notices, and someone at your company approves the first of each kind.

The result notice a recipient reads: Your unsubscribe is done. On 12 October 2026 you refused advertising email from Your store. We have stopped sending it. — A result notice, sent within three days of a refusal, inside the decree's 14 days.

Two-year consent confirmations: 4,120 people before 3 March 2027, draft waiting for approval; 2,860 before 9 April and 1,940 before 2 May, scheduled. — Two-year confirmations, dated before each person's own anniversary of consent.

Every email we send, October 2026: 142 templates, 118 informational and 24 advertising, each with its class and who approved it on which day. Kept in Seoul. — The inventory: every template's class, and who approved it on which day.

If Nalin's model calls a points notice informational and the Commission disagrees, our company still pays the surcharge.

Yes, it still lands on you.

The Network Act fines and surcharges the sender, and no email vendor's contract moves that, ours included.

Two promises are ours: no new or changed template sends unapproved, and every class names who approved it.
