Why LINE in the chat

In Taiwan, Japan and Thailand, many customers read LINE before email. Shops often keep two tools and two lists for the same people. Tellnod keeps one contact list for email, WhatsApp and LINE, so a campaign can go to each customer on the channel they use, with one approval.

What the LINE tools do

  • Connect an Official Account from the chat and check its status.
  • Check quota and cost before a send, on the card.
  • Preview the message as it appears in LINE: text, cards, carousels and Flex messages.
  • Turn an email into a LINE message so one campaign covers both channels.
  • Save reusable modules such as a coupon block or a product card.
  • Prepare the send with the same confirmation card as email: recipients, exclusions and send time.
  • Read results in the chat after the send.

The same approval as email

The assistant prepares a LINE send; only the Confirm button on the card can schedule it. Each confirmation is single-use and expires after 10 minutes. See how sending is protected.

Tellnod and LINE’s own MCP server

LY Corporation publishes an open-source LINE Bot MCP Server for the Messaging API, released as a preview version in April 2025 L1. It runs on your own computer with a channel access token and offers tools such as text and Flex broadcasts, profile lookup, message quota and rich menus L1. It suits developers who want direct API access. Tellnod is a hosted connector for shops: sign-in with Google instead of tokens, one contact list shared with email, a preview of the real message, and a person’s confirmation before every send.

Availability

LINE opens after WhatsApp. Email works today with the same contacts, brand and approval, so you can start now and add LINE when it opens. Details on the LINE page.
