Compliance

Recipients must be able to opt out of your messages, particularly marketing messages. Connect handles this for you with STOP replies, unsubscribe links and a suppression list.

You can manage these settings in PureSMS under Settings → Compliance / Replies.

Suppression list

Every workspace has a suppression list. Messages to a number on the list are not sent, whichever way you send them.

Numbers are added to the list automatically when a recipient replies STOP or uses an unsubscribe link, and you can also add or remove numbers yourself, in PureSMS or with the Suppressions API.

STOP replies

When a recipient replies with exactly STOP, UNSUBSCRIBE, CANCEL, END, QUIT or STOPALL (in any case), Connect adds their number to your suppression list. This works whether they replied by SMS to a virtual number or through a reply link.

Setting	Default	Description
Auto-handle STOP messages via the suppressions list	On	Adds the number to your suppression list when a STOP reply arrives.
Don’t forward STOP messages to webhooks	Off	Stops STOP replies reaching your webhooks. Only applies while auto-handling is on.

STOP replies are always kept in your message history, whatever these settings are.

Unsubscribe links

An unsubscribe link is a short link added to the end of your message. The recipient taps it and confirms, and their number is added to your suppression list.

Don't miss 20% off everything this weekend!
Stop: https://dv.gt/a1B2c3

Unsubscribe links never expire. The recipient has to confirm on the page, so link previews and security scanners can’t unsubscribe anyone by accident.

Adding links to marketing messages

Turn on Append a message link to marketing messages to add a link to every message you send with kind set to Marketing. Choose what the link offers with Link mode:

Link mode	What the recipient can do	Default pre-text
Unsubscribe	Unsubscribe	`Stop:`
Reply	Reply to you (see Replies)	`Reply:`
Both	Reply or unsubscribe	`Reply / Stop:`

You can change the text shown before the link with Pre-text.

Message kinds

Set kind when you send a message to say why you are sending it. This decides whether a link is added:

Kind	Link added
`Transactional` (default)	Only if you set `messageLink.include` to `true`
`Marketing`	When Append a message link to marketing messages is on, unless you set `messageLink.include` to `false`
`Authentication`	Never

{
  "sender": "YourSender",
  "recipient": "+447700900123",
  "content": "Don't miss 20% off everything this weekend!",
  "kind": "Marketing"
}

You can override the link mode and pre-text for a single message with messageLink, for example "messageLink": { "mode": "Unsubscribe" }.
