What's New
🔍 Hackle Event Explorer Launch
Check whether the events you want are being collected correctly, right from your browser. Install it from the Chrome Web Store to see the events and properties fired on a page with your own eyes and immediately verify that your integration works.
No more digging through developer tools — QA and debugging get much faster.
Use Cases
Integration verification Verify right away that newly integrated events actually come in
Check collected data Confirm on-screen that event names and property values are recorded as intended
Shorter QA and debugging time Check collection without opening developer tools, cutting the time spent on QA and debugging
✨ Remote Evaluation
You can now use the user profiles stored on Hackle's servers to determine user distribution and In-App Message eligibility.
Previously, you had to send the User Properties used for Targeting directly through the SDK.
Now the profile information already accumulated in Hackle can be used for server-side evaluation without a separate transmission, so user distribution and In-App Message Targeting are performed using only the properties stored on the server — even when the client does not hold the values.
Use Cases
Distribution based on server properties Distribute A/B Tests, Feature Flags, and Remote Config using properties only the server knows, such as CRM tier or purchase history
More granular In-App Message targets Segment campaign targets with information only the server knows, such as payment status or membership tier
Targeting with no omissions Accurately include even the users who used to be left out of a target because a property was not delivered
Check the Remote Evaluation Guide
📂 User Property Upload
Without any development work, you can upload offline data organized in a spreadsheet or external CRM properties straight into Hackle user profiles as a CSV file. When used together with Remote Evaluation, the uploaded properties are used as-is for Targeting and distribution.
Check the User Property Upload Guide
Improvements
080 opt-out list lookup You can check 080 opt-out numbers and their lists directly in Opt-out Management.
Low cash balance Alimtalk When the cash balance for sending messages runs low, we notify you via Alimtalk.
Recipient list preview before sending You can preview the list of recipients who will actually receive the message before sending it.
Attachments for Alimtalk template review You can attach files when requesting a review of an Alimtalk template.
Array property targeting for scheduled sends Scheduled sends can now target using Array-type properties as well.
✨ User Journey - A/B Test
You can now set up an A/B Test directly inside a journey flow and use data to see which message, channel, or timing drives higher conversion. Without creating a separate experiment, you can add an A/B Test node inside a single journey and go from hypothesis validation to performance analysis in one place.
Try it like this
Compare channels Validate which channel gets a better response among Alimtalk, Push, and Text Message
Compare message content Compare which flow converts better: a group that receives a coupon right away vs. a group that receives content first and then a coupon
Test timing Send the same message 1 hour later vs. 24 hours later to find the optimal timing
🔗 Hackle MCP Remote Server
Connecting Hackle to AI clients such as Claude is now much easier.
Beyond Claude, you can use Hackle right away from a wide range of apps that support MCP, including Cursor, Gemini, GitHub Copilot, n8n, Zapier, Slack, and Notion.
If you are currently using the local MCP server
Support for the local MCP server is scheduled to end in the second half of 2026, and new tools will be added only to the remote server.
With the move to the remote server, the number of MCP tools also grows from 15 to 24. Text Message and Kakao Message lookups have been newly added, and you can now ask AI directly for statistical analysis of the In-App Message, Push, Text Message, and Kakao channels.
Try it like this
Summarize the results of the A/B Test that started last week
Compare the conversion rate of recent push campaigns by channel
Chart the DAU trend and 7-day retention for the last 30 days
Tell me which of the experiments that ended today are statistically significant
📊 User Profile - Phone Number Search Support
You can now search for users by phone number in User Profile. Phone number search has been added to user search, which previously supported only specific IDs such as Hackle ID, User ID, and Device ID.
✨ Cafe24 Non-member Sending
You can now use Cafe24 non-member customers as message recipients. Previously, you could only send messages to registered members, but now you can manage non-member purchasers as well and deliver messages to a broader customer base.
From order confirmations and shipping notifications to repurchase prompts and benefit announcements, you won't miss any touchpoint with non-member customers. Send coupon-issuing messages to non-member purchasers to convert them through sign-up → repurchase. This is also an effective tool for teams looking to drive member conversion.
🔗 Connected Content
Connected Content has launched, allowing you to automatically call an API set up by your team at the moment a message is sent and use the response values directly for message personalization.
You can weave external data such as real-time inventory, real-time discount prices, points, and recommended products into your messages to deliver exactly the right message to each individual customer.
You can enter tags directly in Connected Content, or select and add the variables you want from the [Add Personalization Data] modal. When you enter an API URL in the modal, you can immediately check the response result and insert the value you want into the message in variable form with a single click.
🔁 User Journey Re-entry
You can now configure the same user to automatically re-enter a journey when they meet the entry condition again. The re-entry interval can be specified in units of seconds, minutes, hours, days, weeks, or months, allowing you to flexibly design recurring scenarios over time.
Use Case Scenarios
Repurchase Prompt Purchase completed → wait 7 days → review request notification → wait 30 days → send repurchase coupon
Payment Conversion Automation Free trial started → wait 3 days → key feature guide → wait 7 days → paid conversion prompt message
Incomplete Reservation Drop-off Prevention Reservation started → wait 1 hour → check if incomplete → send Alimtalk → wait 1 day → additional reminder
💌 Custom HTML for Unrestricted In-App Messages
We now support HTML-based custom in-app messages. Going beyond fixed templates, you can freely compose in-app messages tailored to your brand identity and campaign goals. You can directly create formats that previously required a developer, such as roulette/lottery events, promotional banners, star-rating review prompts, surveys, and video-style messages.
Even without knowing HTML code, you can select from pre-built templates and apply them instantly, and quickly create messages in the form you want using the [Ask AI] feature.
💌 Hackle Quick Send Launch
The 'Quick Send' feature, which lets you start sending messages without any separate installation or setup, has launched. Just upload a list of customer phone numbers to instantly send Kakao Alimtalk, Brand Messages, and SMS, and check the results all in one flow.

080 opt-out number supported by default
