Features: Bulk SMS Platform | Frostwood Bulk SMS

Bulk SMS campaigns

Send to many people at once, with the exact cost before you confirm.

Choose contact groups, individual contacts, pasted numbers or an uploaded file.
Personalise with fields such as {Firstname} or {Amount}, from contacts or spreadsheet columns, with fallbacks for missing values.
The review shows valid unique recipients, excluded numbers and why, encoding, segments and the total credits.
Nothing is reserved or sent until you confirm. Owners can require approval for operators’ campaigns.

Your organisation’s name instead of a number.

Apply online with your intended use and supporting documents.
A one-time setup fee per network, shown before you submit and paid by M-Pesa.
Follow every step of the application, including any request for more information.
Only names approved for your organisation appear in your composer.

Keep a clean, consented address book.

Import CSV and Excel files with a column-mapping preview and an error report for rows that need attention.
Numbers are validated and stored in international format; 07…, 01…, 254… and +254… are accepted.
Groups, tags, custom fields and consent source for every contact.
Opted-out numbers are removed from every campaign automatically.

Send at the right time, automatically.

Schedule in East Africa Time.
Credits are held when you schedule, so the campaign can always go out, and return if you edit or cancel.
Promotional messages are sent only between 6:00 am and 6:00 pm; transactional messages can go at any time.

Know what happened to every message.

Each recipient shows submission, delivery and billing separately.
Accepted means the network took the message; delivered means the handset report came back. Unknown outcomes are shown as unknown, never guessed.
Messages rejected before acceptance return their credits automatically.
Download recipient reports as CSV.

Pay as you go, with no monthly fees.

Buy by number of credits or by amount, with an M-Pesa prompt or through our Paybill using your account number.
Credits are added only when Safaricom confirms the payment.
Volume tiers lower the price per credit; purchased credits do not expire.
Receipts and a full credit history in your SMS wallet.

SMS inside your own software.

One request sends a one-time code or a notification; per-recipient values for personalised messages.
Scoped API keys you can revoke, idempotent requests and clear error codes.
Delivery webhooks signed with HMAC-SHA256 and retried.
The same credits, sender approval and opt-out checks as the dashboard.

Built for organisations that handle sensitive data.
