You can now import past conversations into Plain from any tool, including known providers and in-house systems, without a built-in importer.

Imported threads keep their original creation dates and message authors, along with customer emails, agent replies, internal notes, and attachments. Each thread also records when it was imported and who imported it.

Re-running an import skips anything already brought across, so a migration that stops halfway can be started again without creating duplicates. Imported threads don't trigger SLAs or autoresponders.

Examples and instructions on how to get set up are in the API docs.

If you're switching from Zendesk, Freshdesk, Intercom, or Help Scout, use the built-in importers instead.
