Why send bulk SMS in Sri Lanka?
SMS still has the highest open rate of any channel — most messages are read within minutes of delivery. For Sri Lankan businesses, bulk SMS is the most direct way to announce offers, confirm orders, send reminders and reach customers who may not use email or data.
With SMSGo.lk you upload your contact list, write your message in Sinhala, Tamil or English, choose your sender mask, and send to thousands of numbers in a single click.

Unlike gateways that add setup fees, monthly charges or tax on top, SMSGo.lk charges a single flat rate of LKR 0.54 per SMS with everything included. You buy credits once, and they never expire.
