Dedicated IP — when it actually helps.
Your own IP keeps your placement insulated from every other sender. It also means starting from zero, and an IP only earns a reputation from volume you actually send.
Available on request on the Scale plan. Under a few hundred thousand messages a month, the warm shared rail will serve you better — and we would rather say so than sell you an IP.
Five things to know.
Available on request, on Scale
Not a self-serve line item with a price tag, because whether it helps you depends on your volume. Ask and we will look at that with you.
You probably do not need one
An IP only earns a reputation from sustained volume, and the floor usually published for that is around 300,000 messages a month. Below it, a dedicated IP has too little traffic to establish or hold a reputation.
Isolation cuts both ways
Your own IP means other senders cannot affect your placement — and also that you start from zero instead of inheriting a warm record. That trade is only worth it at volume.
The ramp is your real mail
No seed network and no schedule we can sell you. Mailbox providers form their view from opens, replies and complaints from real recipients, so the traffic is what earns the standing.
Same workspace, same SDK
Nothing changes in how you send. Same workspace, same dashboard, same SDK, and you can go back to the shared rail at any time.
The arithmetic behind that, in full: Automated dedicated IP warm-up — and why you probably should not.
The questions we get.
Do I need a dedicated IP?
Almost certainly not. A dedicated IP only helps once you send enough for mailbox providers to form a stable opinion of it — the figure usually published is around 300,000 messages a month. Below that you get a cold IP with too little traffic to warm it, which delivers worse than the shared rail you already have. Abuse protection does not depend on it either: per-agent reputation scoring, suppression at send and complaint auto-suspend are architectural.
What does it cost?
It is available on request on the Scale plan rather than as a priced add-on, because the answer depends on your volume. If you are well under a few hundred thousand messages a month, the honest answer is that you do not need one.
How does the reputation ramp work?
Through your real mail. There is no seed network and no schedule that can manufacture a reputation — throttling volume avoids tripping rate heuristics, but opens, replies and complaints from real recipients are what build standing. Any provider quoting a fixed number of days is quoting a schedule, not a result.
Can I bring my own IP?
No. Bring-your-own-IP is not supported today.
