Use a pool of dedicated IPs

In this article, we will explain how to create and manage a pool of dedicated IPs.

Pools of dedicated IPs, commonly called IP pools, are groups of dedicated IP addresses that are used to manage the sending reputation of your emails.

Why use a pool of dedicated IPs?

Once you have configured at least two dedicated IPs on your Brevo account, you can choose to create a pool of dedicated IPs so that your email campaigns can be delivered more quickly and effectively. To do so, you must associate several dedicated IPs to one sender.

For example, if you create an IP pool of 2 for one of your senders, email campaigns from that sender will be sent at random from each IP (50/50). This will not be visible to your recipient, who will always see the same sender. However, it will allow your ISP to deliver your email campaigns twice as quickly.

💡Good to know
Using an IP pool is particularly important if you send more than 200,000 emails per day.

Before you start 

Create a pool of IPs

To create a pool of dedicated IPs:

  1. In Brevo, click on your name at the top-right side of the screen.
  2. Select Senders & IP and click Senders
  3. Add a sender or click Edit under the name of the sender for which you want to assign a pool of IPs.

  4. Click Manage the pool of IPs to link a new IP address to this sender and create your pool of IPs.

  5. Select which dedicated IP you want to link to this sender. You can select one or several IPs.

  6. Click Save. The dedicated IP you selected has been added to the list of IP addresses linked to this sender.

Your IP pool has now been created, and your email campaigns will be sent at random by one of the IP addresses in the pool, delivering your email campaigns more rapidly. If you selected more than one dedicated IP for a sender, now you must decide the weighting of each dedicated IP when sending email campaigns ⬇️.

Manage the weighting of each dedicated IP

To manage the volume of emails sent by each IP, you can assign a “weight” percentage to each IP.

By default, this weighting is divided between each IP selected. If you only select one IP, the weighting will automatically be 100%. If you add a second IP, the default allocation will be 50% for each of the two IPs. The total of all the IPs must always equal 100%.

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

  • First IP: 80%
  • Second IP: 20%

In that case, the first IP will send most of your emails. Specifically, 80% of the emails will be sent from this IP and 20% from the second.

Change the weighting of an IP

  1. In Brevo, click on your name at the top-right side of the screen.
  2. Select Senders & IP and click Senders
  3. Add a sender or click Edit under the name of the sender for which you want to assign a pool of IPs.

  4. For each IP, enter your chosen weighting in percentage. The total of all the IPs must always equal 100%.

  5. Click Save when you are done.

Use an IP pool via the API

To send an email campaign from the API, you must 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.
