# Keep your existing inbox with Coexist {#keep-your-existing-inbox-with-coexist}


Coexist copies incoming email from Nitrosend to your existing email provider.
You can work in Nitrosend while your team keeps receiving mail in Gmail,
Outlook, Zoho or another provider.

It is optional, and only for an inbox on your own domain. You do not need it to
create a Nitrosend inbox or use a Nitrosend-provided address, and **Email copies**
only appears in Billing once one of your inboxes can use it.


## Choose the right setup {#choose-the-right-setup}


| Where mail arrives first | What to do |
| --- | --- |
| Your existing provider | Choose **Keep your current inbox** and forward a copy to Nitrosend. This does not require Coexist. |
| Nitrosend, with copies to your existing provider | Choose **Receive mail in Nitrosend**, verify onward delivery and enable Coexist for the addresses you want. |
| Nitrosend only | Create your inbox and leave email copies off. |

Coexist copies new incoming mail. It does not import old messages or synchronise
sent mail, folders, read status or deletions between providers.


## Set up email copies {#set-up-email-copies}


1. Open **Inbox → Manage inboxes** and select the address.
2. In its delivery setup, choose **Receive mail in Nitrosend**. Follow
   **Prepare mail setup** to check and verify the existing delivery destination
   before changing DNS. Do not remove your current mail setup first.
3. When the delivery route is ready, use **Email copies** to enable copies for
   that inbox. If you need paid slots, follow the Billing link and complete
   checkout, then return to the same inbox.

The option is available only when the domain receives through Nitrosend and its
onward route has been verified. Buying the add-on does not change DNS or switch
copies on for every address.


## Price and cancellation {#price-and-cancellation}


Coexist is **US$1 per inbox per month**, separate from additional inboxes and
storage. Billing shows the quantity and recurring total before checkout.
Existing included setups keep their agreed terms.

You can stop renewal in **Account → Billing → Inboxes**. Paid access continues
to the end of the term. After that, mail still arrives in Nitrosend, but paid
copies to the other provider stop.

If copies are paused, check the inbox's delivery status and Billing. A payment
confirmation does not replace verification of the onward route.
