Export Suppressions

Export tenant-scoped suppressions as sanitized CSV.

GET /api/suppressions/export

Authentication

Use a full-access OpenSend API key for public API clients. The dashboard also exposes CSV export from the Suppressions page using the authenticated session.

http

Authorization: Bearer os_YOUR_API_KEY

Query parameters

The export endpoint supports the same filters as GET /api/suppressions: q, reason, source, created_after, created_before, domain, and topic_id.

Limits and safety

Exports are immediate and bounded to 1,000 rows. If more rows match, OpenSend returns 413 export_too_large and asks you to refine filters. CSV cells that could be interpreted as spreadsheet formulas are prefixed with an apostrophe before download.

CSV columns

id,email,reason,source,source_email_id,source_message_id,suppressed_at,updated_at

Only rows owned by the authenticated tenant are exported.
