In this article, we'll explain how to use a pool of dedicated IPs to spread out your email traffic across multiple IPs

Before you start 

Set up each of your dedicated IPs in your Brevo account to be able to use them in a pool of IPs. To learn more, check our dedicated article Set up your dedicated IP in Brevo.

What is a pool of dedicated IPs?

A pool of dedicated IPs, often referred to as an IP pool, is a group of dedicated IP addresses used to spread out their email traffic across multiple IPs. This helps maintain the reputation of each IP, improving email deliverability.

Why use a pool of dedicated IPs?

Using a pool of dedicated IPs offers two benefits:

Step 1: Create a pool of dedicated IPs

Once you have set up at least two dedicated IPs on your Brevo account, you'll have the option to manage your pool of IPs. This feature allows you to select which of your dedicated IPs you want to associate with a specific sender.

To create a pool of dedicated IPs:

1. Click your account name and go to Senders, Domains & Dedicated IP > Senders.
2. To assign a pool of dedicated IPs to a specific sender, either create a new sender or click Edit next to the sender you want to manage.
   
3. Click Manage the pool of IPs.
   
4. Select which dedicated IPs you want to associate with this sender. You can select one or several dedicated IPs.
   
5. Click Save to save your pool of IPs.
6. Click Save to save the changes you made to your sender.

The dedicated IPs you selected have been added to pool of dedicated IPs of the sender. Your emails will now be sent at random by one of the dedicated IPs in the pool.

If you selected more than one dedicated IP for a sender, you can adjust the volume of emails sent by each dedicated IP ⬇️.

Step 2: (Optional) Manage the weighting of each dedicated IP

To adjust the email volume for each dedicated IP, you can assign a "weight" percentage to each one.

By default, the weight is evenly distributed among the selected dedicated IPs. If you choose just one IP, it gets 100% of the volume. With two IPs, each gets 50%. The total weight for all IPs should always add up to 100%.

For example, if you have 2 dedicated IPs and set their weights to:

• First dedicated IP: 80%
• Second dedicated IP: 20%

Then, 80% of your emails will be sent from the first dedicated IP and 20% from the second dedicated IP.

Adjust the weighting of an IP

1. Click your account name and select Senders, Domains & Dedicated IP > Senders.
2. To adjust the weighting of each dedicated IP for a specific sender, click Edit next to the sender you want to manage.
   
3. In the Sending rate column, enter the weighting percentage you want to set for each dedicated IP. The total weight for all IPs should always add up to 100%.
   
4. Click Save.

Use a pool of dedicated IPs via the API

• To send an email campaign from the API, you should have created at least one sender in Brevo and associated them with your dedicated IPs.
• If you are sending transactional emails via the API from a sender that has not been set up in Brevo, one of your dedicated IPs will be used at random.
