Do I need a dedicated IP for cold outreach?
Still have a question, spotted an error, or have a better explanation or a source we should cite?
Almost certainly not. Here's the honest answer most ESP sales pages won't give you.
A dedicated IP means your sending reputation is yours alone. No one else's bad campaigns drag yours down. That sounds great until you consider that a cold IP is also a blank IP. With no sending history, mailbox providers have nothing positive to go on. A well-maintained shared pool with a healthy reputation will outperform a fresh dedicated IP for the first several months of warmup.
When a dedicated IP actually makes sense:
- You're sending more than 50,000-100,000 emails per month consistently
- You need complete isolation from other senders for compliance or brand reasons
- You have the internal discipline to maintain warmup and sending consistency
When shared infrastructure is the better choice:
- You're below ~50K monthly sends
- Your sending is irregular (gaps kill a dedicated IP's reputation fast)
- You're just starting out and haven't established a sending cadence yet
The shift in deliverability over the last few years is also worth noting. Domain reputation now carries more weight than IP reputation in most mailbox provider algorithms. Your domain's authentication, engagement history, and complaint rate matter more than whether the IP is dedicated or shared. Focus there first.
If you're unsure which path makes sense for your volume, our SOS call is free and we won't try to upsell you dedicated infrastructure you don't need.
