The collective advice suggests that a dedicated IP address *can* be a good fit for compliant senders who send 1M+ emails weekly, provided they prioritize sender reputation and engagement. Successful implementation hinges on a careful warm-up process, focusing on sending to engaged recipients first and gradually increasing volume. While some emphasize the number of sends over the time period for warm-up, intermittent sending schedules require diligent monitoring using tools like Google Postmaster Tools and Microsoft SNDS. Crucially, maintaining strong email authentication (SPF, DKIM, DMARC) and actively managing complaint rates are essential for long-term deliverability success. The experts caution against sudden spikes in volume, instead advocating for a slow and steady approach, particularly when warming up.
8 marketer opinions
The consensus is that a dedicated IP address can be suitable for a compliant sender with a weekly sending pattern of 1M+ emails, provided certain conditions are met. The key to success lies in maintaining a good sender reputation through consistent volume (high enough even with weekly sends), proper authentication, and careful IP warm-up. Warm-up should be phased, starting with smaller volumes sent to the most engaged subscribers, gradually increasing over time. Monitoring deliverability metrics and using tools like Google Postmaster Tools and Microsoft SNDS are crucial for identifying and addressing potential issues.

5 expert opinions
Experts generally agree that a dedicated IP is suitable for compliant senders with weekly patterns of 1M+ emails. While weekly sending is viable, warming up the IP requires careful planning. Focusing on the number of sends during warm-up, rather than the time period, can accelerate reputation building. Prioritizing engaged audiences during warm-up and consistently monitoring engagement/complaints are crucial, especially given the challenges of intermittent sending.
