The boring pages, written plainly.

Short sections in ordinary English. The formal versions are linked at the bottom of each.

Message text goes to the model providers onlyA masked excerpt, to the primary — or to the backup while the primary is down — and neither keeps it. A message you open in Sortmail passes through our servers and Cloudflare on its way to your browser, and is stored by neither. Everything else on this list sees account records, fingerprints or billing data.

Changes to this list

We give at least 30 days’ notice before adding or replacing any entry, by email and by updating this page. Under the data processing agreement, you may object on reasonable data-protection grounds within that period.

What each one is contractually required to do

Every entry is bound by a written contract imposing obligations no less protective than our DPA, including Article 28(3)(a)–(h). We remain fully liable for their performance.

The model providers carry two extra obligations that the others do not:

  1. Zero retention. The request is processed and discarded; no copy is kept.
  2. No training. The data may not be used to develop, train, improve or fine-tune any model, generalised or otherwise. This is required both by our contract and by Google’s Limited Use rules.
