Own Your IP Reputation.
Own Your Inbox Placement.

For most senders, a high-quality shared IP pool produces excellent deliverability — and is in some cases better than a fresh dedicated IP for new senders, because the shared pool has established reputation history. A dedicated IP is recommended when: your monthly volume exceeds 500,000 emails; you operate in a regulated industry (finance, healthcare) requiring documented IP isolation; you manage multiple brands and need to isolate their reputations; or you are sending both transactional and marketing emails and need separate IPs for each. If you are below these thresholds and your deliverability on shared IP is strong, a dedicated IP adds cost without proportional benefit.

When you receive a brand new dedicated IP, it has zero reputation history — mailbox providers have no data about the quality of mail from that IP. This means a new dedicated IP starts with "Unknown" reputation and must be warmed up over 8 weeks before it can safely send at full volume. A shared IP pool that has been in use for months or years already has established reputation — new senders benefit from that existing goodwill immediately, without a 8-week warmup period. The trade-off: on a shared pool, other senders' behaviour partially affects yours.

8 weeks for most target volumes. The timeline depends on your target daily send volume — smaller volumes (under 10,000/day) complete in 4–6 weeks; larger volumes (50,000+/day) require the full 8 weeks. Migomail manages the warmup automatically — you do not schedule or control the volume increases manually. The warmup ramp adjusts based on real-time reputation signals: if engagement drops or complaint rates rise, the ramp pauses until metrics stabilise.

Yes. Multiple dedicated IPs are available on Growth and Enterprise plans. Common configurations include: one IP for transactional sends (OTP, receipts, notifications) and a separate IP for marketing campaigns; separate IPs for different brands or sub-brands; and multiple IPs for high-volume senders who want to distribute sending load. Each IP has its own warmup schedule, reputation dashboard, analytics, and alert configuration.

IP reputation can decay if you stop sending for extended periods — mailbox providers need regular, consistent signals to maintain "High" reputation status. If you stop sending for 30+ days, reputation may slide from "High" to "Medium." If you stop for 90+ days, you may need to partially re-warm the IP when you resume. For planned gaps, Migomail recommends maintaining a minimum sending cadence (even low-volume sends to highly engaged subscribers) to keep the reputation signals active. Migomail alerts you if your IP has been idle long enough to risk reputation decay.

There is no technical minimum volume for a dedicated IP, but there is an economic and practical minimum. For volumes below 50,000 emails per month, the cost of a dedicated IP typically exceeds the revenue generated by the inbox placement improvement — especially given that the shared pool produces good deliverability at lower volumes. At 50,000 emails per month sending 4 campaigns, the inbox placement lift from a dedicated IP typically generates enough additional revenue to cover the IP cost and produce positive ROI. See the ROI analysis section above for the detailed calculation.

IP addresses are owned by the sending infrastructure provider, not by the sender — you cannot transfer an IP address from one platform to another. When migrating to Migomail, you will be provisioned a new dedicated IP that needs to be warmed up from zero reputation. However, your sending domain reputation (which is separate from your IP reputation and in many cases more influential) transfers with you — so the warmup of the new Migomail IP is often faster than warming a completely new domain. Migomail's deliverability team assists with migration planning to minimise delivery disruption during the transition.
