Each Sending Server has its own subscription, billed monthly or annually through Stripe. This guide covers where to find your billing details and invoices, what happens if a payment fails, how cancelling works, and what each server action does.
To open a server, go to Email Accounts → Sending Servers and click it.
Scroll down a server's page to see how it's being used and what it costs.

Used by lists the campaigns that send through the server, and Activity records everything that has happened to it, from payment to setup to restarts.
If setup can't be finished, your first payment is refunded in full.
Open a server and click Actions in the top-right corner. You only see the actions that apply to that server right now.

| Action | What it does |
|---|---|
| Start | Turns a stopped server back on. |
| Restart | Restarts the server. Your email accounts keep sending as before while it restarts. |
| Stop | Turns the server off. Your email accounts keep sending as before, without this server. |
| Retry setup | Tries setup again on a server whose setup failed. |
| Cancel subscription | Ends the server at the end of the period you've paid for. |
| Resume subscription | Undoes a cancellation before the end date. |
| Terminate server | Deletes a server that never finished setup. You type the server's name to confirm. This can't be undone. |
Stopping doesn't pause billing. A stopped server is still yours and still renews. To stop paying, cancel the subscription.
Terminate is only for servers that never became ready. If setup didn't finish, terminating the server refunds your payment in full. Once a server has been running, use Cancel subscription instead.

What happens next:
Until the end date, the server's page shows a reminder with the date it ends.

Changed your mind? Click Resume subscription in that reminder, or choose Actions → Resume subscription, any time before the end date. Nothing else changes.
Will cancelling or stopping a server stop my campaigns? No. Campaigns using the server send from Oppora's shared network instead. To move them to another server, change the Sending server field on the campaign's Rules tab.
Can I get my IP address back after a server ends? No. When a server is terminated, its IP address is released and can't be reserved for you.
Where do I see what I'm paying for all my servers? The Monthly cost card at the top of the Sending Servers tab shows the total.
Choose which campaigns send through your dedicated server, fix email-account conflicts, and see what happens when a server isn't working.
Give your email accounts their own dedicated IP address. Here's what a Sending Server is, when to use one, and how to buy and set one up in Oppora.
