Dedicated IP, only when it helps

Your own IP insulates your placement from every other sender. It also starts from zero, and only volume you actually send earns it a reputation.

Talk to usView pricing

They told us straight that at our volume a dedicated IP would hurt more than it helped, and that the shared rail would place our mail better. That honesty is why we stayed.

Who a dedicated IP is for

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.

  • Choose a dedicated IP if

    • You send around 300,000 messages a month or more
    • Your volume is steady enough to hold a reputation
    • You want placement insulated from every other sender
    • You can start from zero and earn standing with real mail

  • Stay on the shared rail if

    • You send under a few hundred thousand a month
    • Your traffic comes in bursts, not a steady flow
    • You want a warm record from the first message
    • Your volume is still growing toward that floor
How the warm-up works

How a dedicated IP works

An IP only earns a reputation from sustained volume, and the floor usually published for that is around 300,000 messages a month.

  • Isolation cuts both ways

    Other senders cannot affect your placement, and you start from zero instead of inheriting a warm record. That trade is only worth it at volume.

  • Your real mail is the ramp

    No seed network and no schedule we can sell you. Opens, replies and complaints from real recipients are what mailbox providers judge.

  • Nothing else changes

    Nothing changes in how you send. Same workspace, same dashboard, same SDK.

The questions we get.

What is a dedicated IP?
An IP address that only your mail is sent from. Other senders cannot affect your placement, and you start from zero instead of inheriting a warm record, so the trade is only worth it at volume.
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. The arithmetic behind that, in full: Automated dedicated IP warm-up — and why you probably should not.
How do email services compare on dedicated IPs and warmup?
We compare email services on dedicated IP and warmup options in a guide of its own: Email service that handles dedicated IPs and warmup options.
Should I use a standalone warmup tool?
Most senders skip standalone warmup tools. Why, in full: Email warmup service.
Can I bring my own IP?
No. Bring-your-own-IP is not supported today.
