WHAT

What is Stibee?

Stibee is a Korean-built email newsletter service. It covers subscriber list management, email creation, sending, and performance tracking on one screen, with built-in safeguards for Korean rules such as recipient consent and the (Ad) label.

WHY

What sets it apart

These are the differences we found by running the same material through several tools in our training sessions.

📮

Designed to meet Korean regulations

Subscriber records have a separate field for consent to receive promotional messages. The help pages advise putting (Ad) in the subject line of commercial promotional emails, and a placeholder that inserts an unsubscribe link is provided by default. Compliance controls are built into the features, which is the biggest difference from overseas tools.

🧰

An interface built in Korean from the start

Menus, help, and payment are all in Korean. It is a tool built for Korean users, not a translated interface, so even people outside marketing can send their first newsletter on the day they sign up. Korean help articles are linked wherever you get stuck.

📈

You pay only for the size of your list

The Starter plan is free up to 500 subscribers and 2 sends per month, and paid plans get more expensive as your subscriber tier rises. While your list is small, you can start for under KRW 10,000 (≈ US$7) a month, and the price goes up only as your subscribers grow.

⚖️ The weaknesses are clear, too

It does not handle sales pipelines or deal management. It is a place to send email, not a CRM that tracks clients, contacts, and deal stages. Its AI features are limited to subject line suggestions and sentence polishing, so it will not build segments for you or write a whole draft.

💡 In plain English

Like a meticulous mailroom clerk at the company. It checks first whether you’re allowed to write to someone, then sends each message out in a compliant envelope.

🏢 Why it matters for organizations

In sales, the longest-lasting asset is your customer list. One improperly sent promotional email can cost you more than the list itself, since legal liability follows, so it’s safer to use a tool that handles consent management and sending in one place.

SCENE

Same job, different approach

You’ve been put in charge of the monthly customer newsletter

The old way

  1. Copy the addresses gathered in Excel and paste them into BCC
  2. When an email bounces, you can’t tell which list the address came from
  3. No way to know who opened it
  4. Unsubscribe requests are removed from the list by hand

With Stibee

  1. When uploading to the address book, record whether each person has opted in
  2. Add (Ad) to the subject line and include an unsubscribe link
  3. Who opened and who clicked links is recorded in a table
  4. Subscribers unsubscribe themselves and are removed from the list automatically
USE

Common uses

01

Monthly customer newsletter

Pick just three sections for this month: a case study, a resource, and a schedule. Going out on the same date every month matters more than fancy design.

02

Training and seminar announcements

Split your address book by interest and send each message only to the people it’s relevant to. Response is better than with a full send, and unsubscribes drop.

03

Automatic replies to applicants

With an automated email set up, a confirmation goes out right after someone signs up. Nobody on your team has to reply late at night.

FIT

Who it’s for

Best for

  • ✓Anyone sending a regular newsletter to customers or members
  • ✓Anyone who must comply with Korean opt-in rules
  • ✓Anyone who wants to start right away without wrestling with an English interface

Better served by other tools

  • –Anyone who needs to manage deal stages and win probability
  • –Anyone whose main channels are text messages and Kakao notifications
  • –Anyone who needs automation with complex conditional branching
SECURITY

Can we use it at work?

The questions that adoption leads and security teams ask first.

Is what you enter used for training?We found no notice that email content is used to train models. However, uploading a subscriber list means entrusting customers’ personal data to the service, so before adopting it, be sure to read the privacy policy and the data processing arrangement.
Business and team plansPlans are split by subscriber tier, and moving up to Pro or Enterprise widens the number of users and the scope of permission management. Your team shares a single workspace.
AlwaysNever send promotional emails to addresses that have not opted in. Having received a business card does not give you the right to send marketing emails. And never paste a subscriber list file into any AI tool.

Please note: Stibee’s help pages state that promotional emails must carry (Ad) in the subject line and explain how to unsubscribe, and they advise contacting KISA when you’re unsure. Confirm with legal review how far your company’s mailings fall under these rules.

START

10-minute quick start

  1. 1

    Sign up at stibee.com and create a workspace. Start on the Starter plan with no credit card.

  2. 2

    Create an address book and upload only addresses that have given consent. You can upload them all at once from an Excel file.

  3. 3

    Pick one template and fill in three news items for this month. Don’t try to design something polished from scratch.

  4. 4

    Check the (Ad) label in the subject line and the unsubscribe link, then send a test to your own address first.

PROMPT

Copy-and-paste prompts

Replace only the [bracketed] parts, then paste it in.

10 subject line options
Below is the body of this issue’s newsletter. Write 10 subject lines that would make recipients want to open it. Skip clickbait, and next to each one add a one-line note on which part of the body it’s based on.

[Paste body]
Subject lines with the (Ad) label
The subject line candidates below will appear in recipients’ inboxes with (Ad) in front. Polish each one so it still makes people want to read it even with that prefix, and briefly explain why you changed it.
Drafts by segment
Turn the content below into two draft emails, one for each type of reader: ① a manager who has already taken our training, and ② a manager who downloaded the materials but hasn’t inquired yet. Even if the news is the same, give each draft a different opening paragraph and closing.

[Content to send]
Rewrite the first paragraph only
The first paragraph of the newsletter below is dull. Rewrite just that paragraph in three versions. Don’t open with a greeting; start with the single most useful point in this issue.

[Paste newsletter]

RECIPE

Using it with other tools

Linking two or three tools changes your work more than any single tool does.

A stack of materials → one newsletter

1Use Claude to draft this issue’s three items and the body text
2Create a header image in Miricanvas or Canva
3Paste it into Stibee, send a test, then schedule it

Sign-up form → address book → welcome email

1Use Zapier or Make to send sign-up form responses into your Stibee address book
2Set up a Stibee automated email so a welcome message goes out right away
3Have Claude draft three versions of the welcome email and try them in rotation
CAUTION

Before you start

  • Do not send promotional emails to addresses collected without consent. Business cards and attendee lists are not consent to receive emails in themselves.
  • Never paste your subscriber list file (names, companies, contact details) into an AI tool. Give it only the content, and get drafts back.
  • Don’t forget the (Ad) label in the subject line and the unsubscribe link. If either is missing even once, the entire send becomes a problem.
  • The free Starter plan adds a sponsor banner to your emails. For official notices to clients, use a paid plan.

HONEST

Where Stibee falls short

We don’t just list the positives. Here is what fell short when we used it.

  • The free banner stands out

    Emails sent on the free Starter plan carry a sponsor banner. You wrote the content with care, yet someone else’s ad sits at the end, so for client emails you end up upgrading anyway.

  • Pricing rises with list size

    Pricing is set by subscriber tier, not by how many emails you send. A list you mail only a few times a year still moves up as it grows, so you pay the same even in months you don’t send.

  • The editor can feel cramped at times

    Because you build by stacking blocks, it can be hard to get exactly the layout you want. If you try to fine-tune tables or spacing, you may end up making an image and pasting it in.

COMPARE

Tools to compare

FAQ

Yes, the Starter plan is free. It covers up to 500 subscribers, 2 sends a month, and 1 user, and a sponsor banner is added to your emails. As your list grows, you move up to paid plans by subscriber tier.
Yes. It’s built by a Korean company, so the interface, help docs, and billing are all in Korean. You don’t have to translate terms as you go, as you would with overseas tools.
A widely used newsletter service among Korean companies and institutions. Since you are entrusting it with your subscriber list, check its privacy policy and data processing arrangements before adopting it, and set an internal rule first: no promotional email to addresses that have not given consent.
