If you send a high volume of emails and want greater control over your email-sending reputation, you can purchase and set up a dedicated IP for sending emails through Brevo.

Good to know

Step 1: Purchase a dedicated IP in Brevo

💡 Good to know
Only dedicated IPs purchased from Brevo can be added to your account. Similarly, Brevo dedicated IPs cannot be transferred to other platforms.

You can purchase a dedicated IP directly from your Brevo account.

  1. Click your account name and select My Plan.
  2. Under the Add-ons section at the bottom of the page, click Add dedicated IP.

  3. Click Proceed to checkout.
  4. Enter your billing information and payment method.
  5. Read the Terms of Service and Anti Spam Policy of Brevo and check the box to confirm: I agree to the Terms of Service and Anti Spam Policy of Brevo.
  6. Click Pay now.

The dedicated IP has been added to your account.

❗️ Important
You should not send any emails before you start warming up the IP.

Step 2: Create a subdomain of your primary domain

To set up your dedicated IP, you’ll need to associate it with a subdomain. This subdomain, known as the sending domain, will appear as the mailed-by or return-path domain in your email headers. If you don’t have a suitable subdomain available, you’ll need to create one through your domain host account.

Here are some key guidelines to follow when choosing or creating your subdomain:

  • Use a subdomain of your primary domain, not the primary domain itself (e.g., emails.yourdomain.com). If you have several dedicated IPs, use a different subdomain for each IP (e.g., emails.yourdomain.com, emails1.domain.com, emails2.domain.com, etc.).
  • Make it as similar to your primary domain as possible to make sure your brand is recognizable. 
  • Dedicate it solely to sending your emails from Brevo and do not use it for other purposes (e.g., website, webmail).

Expand the following accordion to view a more detailed example of how you can setup your subdomain and dedicated IP:

⚙️ Setup example for your subdomain and dedicated IP
Sender Email type Sending domain Dedicated IP
marketing@emails.yourdomain.com Marketing

emails1.yourdomain.com

IP 1
transactional@emails.yourdomain.com Transactional

emails2.yourdomain.com

IP 2
❗️ Important
Do not include "brevo" in your sender domain name, as this could lead ISPs to mistakenly think you're impersonating another company.

Step 3: Associate the subdomain with your dedicated IP

Once you've chosen the subdomain to associate with your dedicated IP, you'll need to add specific values, called DNS records, in your domain host account. During this process, you'll copy and paste these values from your Brevo account into the corresponding fields in your domain host account.

Add the name of the subdomain to Brevo

First, add the name of the subdomain to Brevo:

  1. Click your account name and go to Senders, Domains & Dedicated IPs > Dedicated IPs.
  2. Under the dedicated IP address you purchased, click Associate a domain.
    account_associate_domain_dedicatedIP_en-us.jpg
  3. Enter the name of your subdomain you want to associate with your dedicated IP. This is the subdomain you created in Step 2: Create a subdomain of your primary domain.
  4. Click Associate.

Add the DNS record to your domain host

You will now see a page with the DNS records you need to add to your domain host account. Depending on your domain host and configuration, you have to choose between two options to associate your subdomain with your dedicated IP: Simple or Advanced.

Other
❗️ Important

The values provided below may vary depending on your domain host. If you encounter any issues while associating your subdomain with your dedicated IP, we recommend contacting your domain host's support team for assistance with the correct format.

  1. Open a new tab in your web browser and log in to your domain host account.

  2. Navigate to the DNS management page for the primary domain of your subdomain. This is where you'll add your DNS records.

Add the first NS record

  1. Create a new DNS record of NS type.
  2. In Brevo, copy the value from the Hostname/Name field and paste it into the corresponding field of your domain host.
  3. In Brevo, copy the value from the Data/Value field and paste it into the corresponding field of your domain host.
  4. Leave the TTL field as is.
  5. Save your DNS record.

Add the second NS record

You'll repeat the same process for the second NS record:

  1. Create a new DNS record of NS type.
  2. In Brevo, copy the value from the Hostname/Name field and paste it into the corresponding field of your domain host.
  3. In Brevo, copy the value from the Data/Value field and paste it into the corresponding field of your domain host.
  4. Leave the TTL field as is.
  5. Save your DNS record.

Verify if your dedicated IP has been associated with your subdomain

After adding the DNS records to your domain host account, you need to verify if your dedicated IP has been associated with your subdomain.

  1. Go back to Brevo and click Verify and associate at the bottom of the page.
    account_dedicated-IP_verify_en-us.jpg
  2. Once your dedicated IP was successfully associated with your subdomain, a ✅ Value matched message will appear next to each DNS record.account_dedicated_IP_value_matched_en-us.jpg
❗️ Important
It can take up to 48 hours for your dedicated IP to be associated with your subdomain.

Step 4: Assign your dedicated IP to your senders

Next, assign your dedicated IP to your senders. When a dedicated IP is assigned to specific senders, all emails from those senders will be sent from that IP. If multiple IPs are assigned to a sender, you can set the sending rate for each IP.

How to choose my senders?

When choosing your senders, ensure the domain part of each email address (the part after the @, known as the sender domain) is identical or closely related to the subdomain you associated with your dedicated IP in Step 3: Associate the subdomain with your dedicated IP. This consistency improves email deliverability and strengthens your domain’s reputation.

For example, if the subdomain you associated with your dedicated IP is emails.yourdomain.com, you could use @emails.yourdomain.com (identical) or @info.yourdomain.com (closely related) as your sender domains.

❗️ Important
Using an unrelated domain can raise red flags with ISPs and negatively impact your email deliverability. While it’s not a total barrier, it’s best to closely align the subdomain associated with your dedicated IP and your sender domains.

Assign your dedicated IP to your senders

To assign your dedicated IP to a sender:

  1. Click your account name and select Senders, Domains, and Dedicated IPs > Senders.
  2. Create a new sender or edit an existing one.
  3. Click Manage the pool of IPs.
    senders_ip-pool_1_en-us.png
  4. Choose the dedicated IP(s) to assign to the sender.
    senders_ip-pool_2_en-us.png
  5. (Optional) If you assign multiple IPs to the sender, you can adjust their sending rate and manage the percentage of emails sent from each IP. To learn more, check our dedicated article Use a pool of dedicated IPs.
  6. Click Save.

Step 5: Authenticate your sender domain

💡 Good to know

If your sender domain is identical to the subdomain associated to your dedicated IP, you can skip to Step 7: Warm up your dedicated IP, as the subdomain is automatically authenticated when associated with a dedicated IP.

Now, you need to authenticate the sender domain that you used in Step 5: Assign your dedicated IP to your senders. Authentication allows you to verify that the email addresses you’ll use for sending emails to Brevo are authorized to send emails on behalf of your organization.

This process makes your emails appear more reliable to Internet Service Providers (ISPs) and webmail services like Gmail and Yahoo, improving the likelihood of your emails reaching the inbox.

➡️ To learn more, check our dedicated article Authenticate your domain with Brevo.

Step 6: Warm up your dedicated IP

It's now time to warm up your dedicated IP and build a positive reputation with ISPs. You should start by sending small volumes of emails from your dedicated IP, then gradually increase the volume over time.

FAQs

🌐 Can I associate my dedicated IP directly to a domain instead of a subdomain?

You should never associate your dedicated IP with your primary domain. Doing so could potentially disrupt your website, especially if it is hosted on your primary domain.

Additionally, we strongly advise against associating your dedicated IP with a cousin domain of your primary domain. For example, a cousin domain of the primary domain thegreenyoga.com would be news-thegreenyoga.com. Associating a dedicated IP to a cousin domain is a bad practice and is generally frowned upon in the mailing industry.

When emails are sent from a dedicated IP associated with a cousin domain, recipients may struggle to identify the familiar domain of the website they typically visit. This can raise concerns about phishing attempts, as users may question the legitimacy of the emails. Additionally, anti-spam filters tend to regard emails from cousin domains unfavorably, increasing the likelihood of these messages being flagged as spam or suspicious.

For optimal deliverability and to maintain a positive sender reputation, we strongly recommend you always associate your dedicated IP with a subdomain of your primary domain. This subdomain should only be dedicated to sending your emails from Brevo and should be as similar to your primary domain as possible. For example, if your website is thegreenyoga.com, you could choose news.thegreenyoga.com or marketing.thegreenyoga.com as your new subdomain. This ensures that your emails are recognized, trusted, and less likely to be flagged as suspicious or unwanted.

🔑 Can I use a 2048-bit DKIM key?

The default DKIM key generated when adding your domain is a standard 1024-bit DKIM key. If you want to use a 2048-bit DKIM key to enhance your email security, contact our support team and ask them to activate it for your account. Your 2048-bit DKIM key will then appear in your generated DNS records for email authentication with a value starting with sib2k.

sib2k_2048bit.jpg

❗️ Important

If you previously used the 1024-bit DKIM key, update the DKIM record in your domain host with the new value.

🧐 I already have an SPF record on my subdomain. How can I add Brevo's SPF record?

There can only be one SPF record on a given domain or subdomain. If there is already an SPF record, you'll need to combine the value of that existing record with the Brevo value.

To learn more, check our dedicated article Merge multiple SPF records.

⏳ My subdomain still hasn't been associated with my dedicated IP after 48 hours. What should I do?

If your subdomain still hasn't been associated with your dedicated IP after 48 hours, contact our support team and include a screenshot of the DNS records you have added to your domain host.

For domain host-specific requirements, we recommend you reach out to your domain host support.
