How do I send a short link by text message?
Shorten a long homepage address with lsu.kr before pasting it into a text, and it becomes much easier to fit both your message and the link within an SMS-length text. Telling recipients they can add + to preview it first also makes it safer.

What improves when I put a short link in a text?
A short text generally fits within about 80 bytes, and a long original URL can eat up most of that space on its own. Shortening it with lsu.kr produces a short, consistent length like name.lsu.kr/Ab3dE9, leaving room for a greeting or business hours.
See SMS length limits and short links for the exact figures.
How do I avoid being mistaken for spam when using a link in a text?
A link with no sender information is hard to tell apart from a smishing text. It helps to identify who is sending it first, for example "[Our Shop] Booking confirmed: name.lsu.kr/Ab3dE9".
- State who is sending it (shop or store name) at the start of the text
- Add a one-line explanation of where the link leads
- Include opt-out instructions for bulk sends
How do I help recipients check it safely?
Adding a line like "add + to the link to preview it before you go there" at the end of the text reassures customers who are already cautious about smishing.
How do I send a short link by text message?: step by step

Frequently asked questions
Can I use a short link in MMS too?
Yes. You can include an lsu.kr link in MMS body text the same way, alongside an image.
Some sending services wrap links again automatically — is that a problem?
Some bulk sending services wrap links a second time with their own system, which can mean the final domain shown is not lsu.kr. If possible, turn off your sending service's link-wrapping feature and use the lsu.kr link as is.
Does the link get cut off if I go over the character limit?
The lsu.kr link itself is short and a consistent length, so it is unlikely to be cut off, but if the overall text goes over the limit, your sending service may automatically switch to long format or split it into multiple messages.
Can I change the destination of a link I already sent?
Yes. The link address in a text you already sent stays the same — you can just change the destination. See managing and editing a short link.
Can I test a bulk send before sending it to everyone?
Yes. Send yourself one text first to confirm the link opens correctly and the message length is as expected before sending it to the full list.
Can I reuse the same link for a recurring reminder text?
Yes. As long as the destination page stays the same, you can keep reusing the same lsu.kr link, and only update the destination if the page address changes.
Can I use this for texts sent to overseas customers?
Yes. An lsu.kr link works the same regardless of language, so it saves characters in an English-language message the same way it does in Korean.
