Opt-outs, quiet hours and caps
STOP, ACHA and SITAKI, suppression levels, quiet hours, frequency caps and election silence.
Opt-outs#
A person can stop your messages at any time by replying:
- STOP
- ACHA
- SITAKI
and common variants of these words. Opt-outs:
- take effect immediately, before any other processing of the reply;
- apply to every send, journey, retry, recurring occurrence and survey;
- cannot be switched off by any setting, by your organisation or by Sauti.
Every SMS ends with the opt-out instruction, added automatically.
Suppression levels#
| Level | Set by | Effect |
|---|---|---|
| Channel | Opting out on one channel | No more messages on that channel from your organisation |
| Organisation | A person asking your campaign to stop everything | No messages from your organisation on any channel |
| Platform | An objection to political messaging, an erasure request or a complaint | No messages from any organisation on Sauti |
The platform suppression list stores only one-way hashes, never the numbers themselves.
If a person later wants to hear from you again, they must opt back in themselves. Your team cannot re-subscribe them.
Quiet hours#
National quiet hours are 21:00 to 07:00 Nairobi time. Promotional messages are not delivered during quiet hours. You can extend quiet hours in Settings › Organization, never shorten them. For each send you choose whether recipients reached at quiet hours are deferred to the morning or skipped.
Frequency caps#
Set the maximum number of messages one person can receive per day and per week in Settings › Organization. Your plan may set a lower cap. The composer warns you how many people may hit a cap.
Election silence#
During legally mandated campaign-silence periods, the Sauti team switches on an election-silence window that blocks all promotional sends for every organisation. Plan your last messages before the window starts.
