SMS services for businesses
Everything JaSMS can do, in one place — the same platform behind the portal and the API.
Bulk SMS and campaigns
Reach customers with offers, news and reminders without a marketing tool.
- Send to groups, imported CSV lists or pasted numbers
- Personal fields such as first name in every message
- Cost preview and test send before the campaign goes out
- Schedule for later and send in batches
- Unsubscribed recipients are skipped automatically
SMS API
Connect a shop, booking system or app with a few lines of code.
- Send one message or thousands in one call
- Status, cost and parts returned for every message
- Webhooks for queued, sent, delivered, failed and received
- Idempotency keys so a retry never sends twice
- Restrict each key: destinations, sender, number of parts
One-time codes (OTP)
Verify phone numbers and logins without building it yourself.
- Start and check endpoints — we generate and verify the code
- Expiry, attempt limits and lockout built in
- Codes go ahead of campaign traffic
- Codes are stored hashed, never as plain text
Two-way SMS and numbers
Let customers answer: confirm a booking, reply to an offer, sign up with a keyword.

Links and click tracking
Put links in messages without paying for an extra part.
