Unused credits expire 24 hours after purchase. Standard credits never expire. Bundle credits are used first (soonest-expiring first); any remainder overflows to your standard wallet.

How it works

Built into every send.

No flags to set and no code to change. Buy a bundle and Bulkit routes your messages through it automatically — from the dashboard and the API alike.

Lower per-SMS rates
Lock in rates as low as KSh 0.40/SMS for your chosen window — well below standard entry pricing.
Automatic priority (FEFO)
Bundle credits are consumed first across dashboard campaigns and API calls, soonest-expiring first.
Split billing
A broadcast bigger than your bundle overflows seamlessly to your standard wallet at your normal rate.
Developer API
Read bundle_credits and send with a KSh 0.00 cash balance. Covered messages return a cost of 0.00.

Zero-cash sending.

Poll GET /api/v2/account/credits to read your active bundle credits, then send as usual. With credits available, messages dispatch even at a KSh 0.00 cash balance — and covered sends return a cost of 0.00.

No code changes required.

  "status": "success",
  "data": {
    "balance": 150.50,
    "bundle_credits": 429,

Validity

Three windows. One simple rule.

Each bundle is a separate, time-boxed wallet. Use it within its window; unused credits expire at the deadline. Your standard credits are never affected.

Standard credits never expire.

Smart Bundles sit alongside your regular wallet, not inside it. Bundle purchases and expirations are completely isolated — your non-expiring standard float is never touched.

Stack bundles

Hold several active bundles at once. Credits expiring soonest are always used first (FEFO).

Split billing

A broadcast larger than your bundle seamlessly overflows to your standard wallet.

Automatic refunds

If a message fails during dispatch, its credit returns to the originating active bundle.

Full rate card

Every bundle, every rate.

All 15 Smart Bundles across daily, weekly and monthly windows, with the effective per-SMS rate and savings against the standard entry rate.
