Changelog

Manage plan: going down (fewer calls per day or a shorter commitment) is now scheduled for your next renewal. You keep your plan until then, nothing is charged or credited, and you can cancel the change at any time. Going up is still immediate.

Guides: type your question in the search box and Léa answers from our documentation. The Pricing page now details the daily volumes and the automatic discount from 5 Pro mailboxes.

New illustrated guide: changing plan when you are already Pro (daily volume, commitment, what you pay).

Manage plan: choose your daily volume (500 to 6,000 calls) and commitment yourself, move a Pro to another mailbox, delete a Pro mailbox at the end of its period and edit your billing details for your next invoices. The volume discount now applies automatically from 5 Pro mailboxes.

Illustrated guides: connect Claude, connect ChatGPT, add a mailbox, mailbox settings, manage your Pro plan and verify your email, with a screenshot for every step.
