Send from a group of high-quality IPs whose reputation Mailpro actively manages for you. Spreading volume across several IPs looks natural to mail servers, so your emails go out fast — and you never have to monitor an IP yourself.

An IP pool is a group of IPs we assign to you for your sending. Depending on the quality of the addresses and content you send, you're placed in an IP pool category shared with senders of similar quality — send good content to good addresses and you earn a better pool.
Pools are a great way to make sure your emails go out fast. It's better for deliverability to send 100,000 emails across different IPs than through one: mail servers see spread-out sending as natural, whereas 100,000 messages from a single IP can look suspicious and hurt your delivery rate. We manage the pool's reputation and monitor the IPs closely, so you don't have to — our team's vigilance and a strict zero-spam policy are what give us rock-solid deliverability.
Compare that with a single dedicated IP. If you push a high volume through one IP without properly warming it up first, mail servers see every message arriving from a fresh IP, which looks suspicious — and your emails can land in Spam. And even a warmed-up dedicated IP isn't fully in your control: if another IP in the same range is blacklisted, it can drag down the reputation of yours too. With a single IP, that's a real risk because you only have one. A pool spreads that risk and keeps you delivering.
There are pros and cons to both approaches, but for most customers we recommend a dedicated IP pool: we have the expertise, the team of professionals to manage the IPs' reputation, and the infrastructure to take the weight off your shoulders when it comes to delivering your emails. Prefer full control instead? For some customers we also offer a single dedicated IP, depending on your specific sending needs and requirements.
