Unlimited plan
Setting up your own AI provider key
The Unlimited plan lets you use your own AI provider's API key instead of paying Mail for managed AI access. You manage that provider's billing and limits directly — Mail just uses the key you provide to make AI requests from your device.
1. Get an API key from a compatible provider
Sign up with a compatible AI API provider and generate an API key from their developer dashboard. Keep it somewhere safe — you'll paste it into Mail in the next step, and it won't be shown again by most providers.
2. Add the key in Mail
In the app, open Settings → Subscription, and select Configure API Key under the Unlimited plan section. Paste your key and save — Mail stores it locally on your device and uses it directly for AI requests going forward.
3. Confirm it's working
Try an AI action (e.g. drafting a reply or summarizing a thread). If the key is rejected, double-check it was copied in full and that your account with that provider has available usage/billing set up.
Costs and limits
Your AI usage is billed directly by your chosen provider according to their pricing — Mail doesn't add a markup or cap on top of what your provider allows. Your Mail subscription fee covers the app itself, not AI usage, on this plan.
