Key Takeaways
- A bulk campaign checklist vs RBSoft / Ozeki stacks is STOP, pacing, and SIM isolation — vendor chrome is secondary.
- Do not rewrite competitor overview hubs. This is a pre-send gate.
- Never hammer a single modem. Raise OEM/Android SMS rate ceilings carefully; carrier fair-use still applies.
- OTP SIMs do not join the blast pool “just this once.”
- CSV without consent flags is not a list. It is an incident.
- You bring phones and operator credit. Platform fee is devices + send volume.
Bulk is consent plus a modem
Bulk campaign checklist for competitors (RBSoft / Ozeki) is the gate before a CSV leaves any Windows panel, SMPP bind, or paired Android. The product chrome differs. The radio, the regulator, and the prepaid pack do not.
Hubs: RBSoft alternatives, Ozeki comparison. Product bulk: bulk SMS. Sister gate: API production readiness.
“If STOP is a slide and not a handler, do not press send.”
Competitor hubs stay hubs
Buyer history, license risk, and Windows service ops stay there. This page is pre-send only. No piracy queries. Live params for this product: Developer Center.
Campaign gate
| Item | Why | Verify |
|---|---|---|
| Consent flag on every row | Imported Excel lies | Reject rows without it |
| STOP inbound path | Replies hit a SIM | Auto-reply / STOP |
| Quiet hours in recipient TZ | UTC jobs wake people | Quiet hours |
| OTP pool excluded | Blast holds the radio | Device id not in bulk worker |
| Pace under OEM + carrier | Ceilings and fair-use | Canary RTT during a drip, not idle |
| Voucher + platform cap | Free/Developer pause | Named top-up owner |

Pacing vs OEM ceilings
Raise Android/OEM SMS rate ceilings; Starter, Professional, and Business list Unlimited SMS as platform send volume, not unmetered carrier SMS. Concatenated UCS-2 doubles PDUs. Acceptable use.
Cost
Operator segments + device SKU + platform volume. We do not refund airtime on a bad list. Pricing.
Printable close
- Consent, STOP, TZ, isolation, pace, voucher — evidenced.
