Allow & block lists - SentFromAI

Allow/block rules let you explicitly permit or deny specific addresses or domains, on top of the automatic suppression of bounces and complaints.

Add a rule

curl -X POST https://api.sentfrom.ai/v1/lists \
  -H "Authorization: Bearer sf_live_…" -H "Content-Type: application/json" \
  -d '{ "kind": "block", "direction": "outbound", "pattern": "competitor.com" }'

Field	Values
`kind`	`allow` or `block`
`direction`	`inbound`, `outbound`, or `both`
`pattern`	A full address (`spam@x.com`) or a bare domain (`x.com`)

List and remove with GET /lists and DELETE /lists/{id}.

How rules apply

Block (outbound) — sends to a matching recipient are dropped; if none remain, the send returns 422.
Block (inbound) — mail from a matching sender is rejected before it reaches an inbox.
Allow — explicitly permits an address that might otherwise be filtered.

Automatic suppression

Separately from your rules, SentFromAI maintains an automatic suppression list: any address that hard-bounces or files a spam complaint is suppressed so you never send to it again. This is managed for you — it protects your sending reputation without any configuration.
