Sender IDs
Request a sender ID once. We submit it to the carrier on your behalf, track the decision, and surface the status — including any rejection reason — back in your dashboard.

Message classes
Carriers approve a sender ID for one or more classes of traffic. We enforce the allowed classes at preflight — so you never dispatch a message type the carrier hasn't sanctioned.
| Class | Default status | Typical use |
|---|---|---|
| OTP | Allowed | Login codes, verification. |
| Transactional | Allowed | Order updates, receipts, alerts. |
| Service update | Allowed | Account changes, schedule shifts. |
| Reminder | Allowed | Appointments, renewals. |
| Marketing | Separate approval | Requires separate marketing-class approval. |
What approval usually looks like
Not every submission lands the same way. These are the three outcomes we see most often — and the concrete next step on your side in each case.
Approved quickly
Usually within 24 hours
Your sender name matches the company on record, the use case is specific, and the sample message reads transactional. You'll see an approved status in the dashboard and can start sending immediately.
What you do next
Request a wallet top-up and draft your first campaign.
Pending review
24–72 hours, sometimes longer
The carrier reviewer has set it aside for a second look — common for fintech, crypto, or loan-related names, or when the use case is underspecified. No action needed on your side while it's pending.
What you do next
Nothing right now. If it's open past 72 hours, reach out and we'll escalate directly.
Rejected, then resubmitted
Fresh review after edit
If the carrier rejects the name, the reason lands in your dashboard — usually a prohibited keyword, unclear use case, or impersonation risk. You edit the fields and resubmit from the same ticket.
What you do next
Adjust based on the reason shown. Most resubmissions are approved on the second attempt.
Rejections
The carrier's rejection reason comes back to you in the dashboard. You can adjust the name and resubmit without starting a new ticket.

Impersonation risk
MTN-ALERT, GTBANK-NEW

Unclear use case
Submission without sample message or purpose.
