Subscribe, change commitment, cancel or get refunded: everything is done from the plan page of each mailbox, without writing to support.

Short answer: Pro is billed per mailbox. In Email accounts, click "Upgrade to Pro" on the mailbox (or "Manage plan" if it is already Pro). On that page you choose monthly (€7.99), 12 months (€2.99/month) or 24 months (€1.99/month), switch with "Switch to this plan", cancel with "Cancel subscription" (Pro stays active until the end of the paid period), or, within 7 days of your first payment, click "Cancel and get refunded".
Pro is per mailbox: click "Upgrade to Pro" on the mailbox you want to upgrade. On a mailbox that is already Pro, the button is called "Manage plan".
Pick monthly, 12 months or 24 months, tick "I have read and accept the Terms and Conditions" and click Subscribe. You pay on Polar's secure page; Pro is active as soon as the payment goes through.
On the plan page of a Pro mailbox, select another commitment and click "Switch to this plan". Your subscription is updated in place: no new card entry, any price difference for the current period is charged right away and the new price applies from the next renewal.
In the "Active Pro subscription" box at the top of the page, click "Cancel subscription". You keep Pro until the date shown, then the mailbox goes back to the free plan. A Reactivate button stays available until then.
During the 7 days after the first payment of your account, the page shows the money-back guarantee. Tick "I want to cancel Pro now and be refunded", then click "Cancel and get refunded": the full amount goes back to your card and the mailbox returns to Free immediately.
One guarantee per account, on its first paid subscription only, and not if the mailbox already sent more than 20 emails. If the box is not shown, the guarantee no longer applies: you can still cancel at the end of the paid period.
Your email address is not verified yet. Click "Resend email" in the yellow banner at the top of the dashboard, then click the link you receive.
No, Pro is tied to the mailbox it was bought for. Within 7 days you can get refunded and subscribe the right mailbox; otherwise cancel at the end of the period and subscribe the other mailbox.
Pro mailboxes can move to 1,000, 1,500, 3,000 or 6,000 calls per day. Use the "Contact us to change the quota" link on the plan page: support switches your subscription within minutes.
Click "View my invoices" at the bottom of the plan page, or open Profile, Billing tab. Invoices are issued by Polar with the company details entered at checkout.
