This paragraph should probably mention that this won’t work if the provider uses E2EE: “Using secure email providers means that a lot of trust is placed into the provider itself. A failure or a breach of the provider can result in the content of your emails being disclosed, which means you should choose a provider you trust, ideally with a good track record and some formal certifications that attest at least basic security. However, the attacks that are specific to this setup are complex and expensive. Unless you are a high profile target, it’s very unlikely they will ever be relevant to you.”
