Dedicated IP email service
Send from an IP address that's yours alone, with warm-up, reverse DNS and monitoring handled for you. Flat pricing, no per-email fees.
What a dedicated IP changes
Gmail, Outlook and Yahoo decide where your mail lands partly by the reputation of the IP it comes from. On a shared IP, that reputation is pooled across every customer using it: a well-run pool can carry you, and a careless neighbour can drag you down. On a dedicated IP, the reputation is built only from your own sending.
That cuts both ways. A new dedicated IP has no history, so it must be warmed up, and your own bounces and complaints land on it with nothing to soften them. That's why a good dedicated IP service is mostly about what surrounds the IP: warm-up, monitoring and guardrails.
Who it's for, and who it isn't
- A good fit: you send 250,000 or more emails a month, every week, to people who asked for them: product notifications, receipts, alerts, newsletters with real engagement.
- A good fit: your delivery has suffered on a shared pool for reasons outside your control, or you need a predictable sending reputation for a high-stakes stream like password resets.
- Not a fit: under about 200,000 a month, or bursty sends with long quiet gaps. A shared pool usually does better, and it's cheaper.
- Not a fit: purchased or scraped lists. No IP fixes that, and we don't accept them.

What we handle for you
- The IP itself: your own server and dedicated IP (two on Scale 1M), reverse DNS that matches, TLS, and per-domain DKIM keys.
- Warm-up: a schedule built from your real volume and engagement, moving traffic over gradually while your current provider carries the rest.
- Guardrails: hard bounces and spam complaints suppress the address automatically, and sending pauses if bounces pass 5% or complaints 0.3%, before Gmail and Microsoft act on it.
- Monitoring: the IP is checked against the major blocklists every hour, read correctly (Spamhaus refusals aren't reported as listings), with a daily summary of bounces, complaints and queue health.
- One-click unsubscribe: added to marketing mail automatically, as Gmail and Yahoo require.
- Your data in Claude: ask about delivery, bounces and complaints in plain English with our Claude connector.
You send through a Resend-style REST API or SMTP on port 587, so switching is usually a base URL and an API key. Provider-specific steps: from Resend and from SendGrid.

Frequently asked questions
What is a dedicated IP email service?
An email sending service where your mail goes out from an IP address no other customer uses. Mailbox providers like Gmail judge each sending IP by its history, so on a dedicated IP your delivery reflects only your own sending, good or bad. The service should also warm up the IP, set reverse DNS and watch blocklists and complaint rates for you.
How much does a dedicated IP for email cost?
As of October 2026: Amazon SES charges $24.95 a month per IP, Resend $30 (Scale plan), Postmark $50 (Pro plan, 300,000+ emails a month) and Mailgun $59 per extra IP, while SendGrid includes one on Pro plans and Mailgun one on Scale. Our Scale plans include one or two with the plan (early access). Confirm on each vendor's pricing page.
Who should not get a dedicated IP?
Senders below roughly 200,000 emails a month, or with irregular volume, like a monthly newsletter and little else. A dedicated IP needs steady traffic to keep a reputation; without it, a provider's shared pool usually delivers better. Fix authentication and list quality first: they matter more than the IP. See shared vs dedicated IPs.
How long does it take to warm up a dedicated IP?
Usually 2 to 6 weeks, depending on your target volume. Reaching a million emails a month typically takes 4 to 6. You start with tens or hundreds of emails a day to engaged recipients and increase as providers accept the mail, while your current provider carries the rest. Our IP warm-up guide has a schedule.
Can I keep my current email provider while moving to a dedicated IP?
Yes, and you should. You add the new service's DKIM key and SPF entry next to your existing ones, send a growing share of traffic through the new IP over a few weeks, and cancel the old plan once the new IP carries full volume with good inbox placement.
Sending 250,000+ emails a month?
Tell us your volume and current provider, and we'll tell you honestly whether a dedicated IP will help.
