DEDICATED IPS Dedicated IPs and rotation

Dedicated IPs and rotation. Your reputation, never a shared pool.

On a shared pool your inbox placement is an average of strangers, and a stranger's bad campaign is not something you can repair. Here the only sending history on the IP is yours, rotated across a pool sized to your volume and configured to accept cold and purchased data.

Shared vs dedicated

On a shared pool, your reputation is an average of strangers.

Most mainstream platforms send everyone from the same pool of IPs. It works fine until it does not, and the part you cannot control is the part that decides your placement.

Shared pool

Someone else's sending decides your placement

The default nearly everywhere, and the reason a campaign can degrade without you changing anything.

A bad sender on the same pool damages your placement
No way to isolate a problem, because the reputation is not yours to repair
Cold or purchased data usually breaches the terms outright
Cheap, and appropriate for low-volume opted-in mail

Dedicated

The only sending history on the IP is yours

What you get here on every plan, from the $249 tier upwards.

Your behavior is the only input to your reputation
A problem is isolated, diagnosable and fixable, because it belongs to you
Configured to accept cold, purchased and consumer data
Volume rotates across several IPs rather than concentrating on one

The alternative

The other way to send a million a month.

Mailbox-based tools get there by buying inboxes. It works, and it is worth seeing the shape of it at volume before choosing that route.

One million emails a month, on mailboxes

≈ 800 inboxes

At the commonly cited safe rate of 30–50 sends per inbox per day. Each square is one mailbox you'd buy, warm, monitor and pay for.

Before you've written a single email: 800 mailboxes, hundreds of domains, and the seat costs to match.

The same volume here

18 dedicated IPs

Volume rotated across IPs and domains that belong to you alone, warmed and monitored automatically.

One account, one plan, no inbox farm to run.

Rotation

Why volume moves across IPs instead of sitting on one.

No single point of damage

Concentrating a whole campaign on one IP means one bad segment takes the whole program down with it. Spread across a pool, the same mistake costs you one IP and a ramp rather than everything.

Volume ceilings stay out of the way

Providers throttle per IP. Rotation keeps each one under the rate that triggers throttling, which is how a large send finishes on schedule instead of queueing behind a limit.

Segments can be separated

Cold discovery and engaged follow-up do not have to share a reputation. Rotation groups let the risky traffic and the valuable traffic run on different infrastructure from the same campaign builder.

How many you get

IP count scales with volume, and so do the domains.

More volume needs more IPs, not a harder push on the same ones. Free sending domains scale alongside them, because reputation attaches to the pair.

Plan	Dedicated IPs	Free sending domains
$249 · 100,000 a month	2	2
$349 · 250,000 a month	6	4
$499 · 400,000 a month	10	6
$999 · 1 million a month	20	10
Enterprise · to 200 million	100+, on a dedicated server	Scoped with you

Full plan detail is on the pricing page. If you would rather send through providers you already pay for, the SMTP relay system rotates your own SendGrid, Mailgun or Postmark accounts alongside these IPs.

Questions

Dedicated IPs and rotation, answered.

What is a dedicated IP?

A dedicated IP is a sending address used by one customer only, so the sending history attached to it is entirely yours. On a shared pool your reputation is an average of everyone sending from it, which means another customer's bad campaign can lower your inbox placement without you changing anything. Dedicated IPs make reputation something you own and can therefore repair.

How many dedicated IPs do I need?

It scales with volume rather than being a preference. Plans here run from 2 IPs at 100,000 emails a month to 20 at a million, and 100 or more on enterprise volumes. The number matters because providers throttle per IP, so too few IPs for your volume means throttling regardless of how good your reputation is.

What is IP rotation and why does it matter?

Rotation spreads a campaign's volume across several IPs instead of concentrating it on one. It does three things: no single IP carries enough volume to trigger provider throttling, one damaged IP does not take the whole program down, and different segments can be kept on different infrastructure so cold discovery does not share a reputation with engaged follow-up.

Can I send purchased or cold lists from these IPs?

Yes, and it is what they are configured for. Mainstream shared pools generally prohibit it outright. The condition here is that the data is verified first and the send is ramped properly, which protects the IP reputation for you and for every other sender on our infrastructure.

What happens if one of my IPs gets blocklisted?

It is isolated, which is the whole point of dedicated infrastructure. Rotation moves volume off it, the cause gets diagnosed against placement and blocklist data, and delisting is applied for where required. On our standard neutral IPs, a burnt IP is replaced automatically rather than repaired, because those are designed as a replaceable layer for cold discovery.

Do I need dedicated IPs, or would mailboxes do?

It depends entirely on volume. At a few hundred sends a day, mailbox-based tools are the cheaper answer and we would tell you so. At a million a month the mailbox route needs roughly 800 inboxes to buy, warm, monitor and pay for, which is a different kind of operation from one account with a rotating IP pool.

Tell us your volume and we will size the pool.

IP count is arithmetic, not a preference. Give us your monthly volume and your data type and we will tell you how many IPs it needs, and whether a cheaper plan covers it.

Reputation you own is reputation you can fix.

That is the whole argument for dedicated infrastructure. Tell us what you send and we will size the pool and the ramp with you.
