Dedicated IP
An IP address that only your workspace sends from, as a paid add-on for high volume.
Details
- Mail normally leaves through IP addresses shared with other workspaces, which suits most senders because mailbox providers already trust them. A dedicated IP is an address only your workspace sends from, so its reputation is yours alone.
- It is a paid add-on for workspaces on the Business or Enterprise plan that sent at least 100,000 emails in a month, with one IP per workspace. Below that volume a dedicated IP delivers worse than the shared ones.
- The workspace owner buys it, and turns it off, on the Sending tab of the workspace settings. Once it is paid, the IP is assigned within minutes and then warmed up over several weeks: it takes on more of your mail each day, and the rest still leaves through the shared IPs. The Sent tab of Settings → Analytics shows how far the warm-up is.
- Cancelling keeps the IP until the end of the month already paid for. After that it is released, and mail leaves through the shared IPs again.
- The add-on is on the REST API as GET /billing/add-ons, POST /billing/add-ons/checkout and DELETE /billing/add-ons/dedicated-ip, and the IPs as GET /sending/dedicated-ips. The SDK has billing.listAddOns, billing.startAddOnCheckout, billing.cancelAddOn and sending.listDedicatedIps, the command line has the same, and the MCP server has listBillingAddOns, startAddOnCheckout, cancelAddOn and listDedicatedIps.
