What's included
A complete SMS operation, not just a gateway
Everything between “we need to text our customers” and “it's delivered” is built in — no bolt-ons, no third-party tools.
Campaigns
Broadcast to groups, uploaded files, or pasted lists. Send now or schedule for later, and watch progress update live as messages go out.
CSV & Excel personalisation
Upload a spreadsheet and every column becomes a merge field. Each recipient gets their own message — name, balance, due date, anything.
Contacts & groups
Import your audience once, organise it into groups with optional signatures, and target exactly who should hear from you.
Blacklist & opt-out
Opted-out numbers are excluded from every send automatically. Compliance with Kenya's data protection rules is the default, not an option.
Branded sender IDs
Messages arrive from HOSPITAL, SACCO, or SCHOOL — not a random number. We handle registration across all networks end to end.
Message templates
Save the messages you send often, complete with placeholders, and reuse them across campaigns and quick sends.
Duplicate protection
The same message to the same number on the same day is caught before it costs you — unless you explicitly allow repeats.
Delivery reports & exports
Per-message delivery status the moment the network confirms it, with filterable history and one-click CSV exports.
REST API & SMPP
A clean REST API for applications, SMPP binds for high-throughput systems, and webhook delivery reports for both.
Campaigns
From spreadsheet to 12,000 inboxes — no developer needed
Upload a CSV or Excel file, and the columns become placeholders you drop straight into your message. Pick a send time, hit launch, and follow delivery live.
- Merge fields from any column — names, balances, dates
- Schedule ahead or send immediately
- Live progress with per-recipient delivery status
- Invalid numbers flagged instead of silently billed
Campaigns
Hello {{name}}, your balance is {{balance}}members-march.xlsx · 12,500 rows · columns mapped to placeholders
Audience
Your audience, organised and protected
Contacts live in groups you control. Opt-outs land on a blacklist that every send respects — campaigns, quick sends, and API traffic alike.
- Bulk import contacts with names and details
- Groups with optional message signatures
- One blacklist enforced across every channel
Groups
Sender IDs
Be a name, not a number
An alphanumeric sender ID puts your brand at the top of the message thread. We manage the registration process with every Kenyan operator so you apply once and go live everywhere.
- Up to 11 characters — SACCO, SHULE, KLINIK
- Registered on Safaricom, Airtel, Telkom & Equitel
- Approval status visible in your dashboard
Your name on every network
One application — we run the registration with each operator on your behalf.
Developers
An API your team will actually enjoy
Single sends, bulk sends, and personalised batches over REST — or bind over SMPP when you need raw throughput. Delivery reports stream to your webhook the moment networks confirm.
- Simple bearer-token authentication
- Bulk and personalised batch endpoints
- SMPP for high-volume transactional traffic
- Webhook delivery reports with tracking IDs
curl -X POST https://api.mobilesasa.com/v1/send/message \ -H "Authorization: Bearer $TOKEN" \ -d senderID="MOBILESASA" \ -d phone="07XXXXXXXX" \ -d message="Your OTP is 482913"

FAQ
Common questions
How fast do messages deliver?+
Messages dispatch within seconds of sending. Transactional traffic like OTPs is prioritised ahead of bulk campaigns, so time-sensitive messages never queue behind marketing blasts.
Can each recipient get a different message?+
Yes. Upload a CSV or Excel file and reference any column as a placeholder — {{name}}, {{balance}}, {{due_date}} — and every recipient receives their own personalised text. The API supports personalised batches too.
What happens to numbers that opt out?+
They go on your blacklist and are automatically excluded from every future send — campaigns, portal sends, and API calls. You stay compliant without thinking about it.
Do you support long messages and special characters?+
Yes. Long messages are split and rebuilt on the handset automatically, and Unicode is fully supported. You always see the part count — and the exact cost — before you send.
Can I schedule campaigns in advance?+
Yes. Pick any future date and time and the campaign launches itself. You can review, edit, or cancel scheduled campaigns any time before they fire.
