Dedicated IP addresses
What are dedicated IP Addresses?
An Internet Protocol (IP) address is a unique numerical address that defines a location. At Twilio SendGrid, you'll receive a dedicated IP address with either a Pro Email API plan or an Advanced Marketing Campaigns plan. If you have one of these accounts, you can purchase additional IP addresses dedicated to your account. For more information, see our pricing page. Since you are the only one sending email over this IP, the sender reputation associated with this IP is determined purely by your sending practices.
Why would I want a dedicated IP address?
If you are sending any significant amount of email, we typically suggest sending your marketing and transactional emails from separate IP addresses. In order to do this, you'll need to set up IP Pools. In addition, it is strongly recommended to associate your sending domain with your new outbound IP address (provided to you by SendGrid). This is available at no extra cost and can be accomplished by completing an rDNS setup for your dedicated IP.
We also suggest having at least 2 promotional IP addresses when your volume reaches 200-300K/month.
Do I have a dedicated IP address?
Depending on the plan you have chosen, you either have a dedicated sending IP address or you are using a shared sending IP address.
- All Pro or Premier Email API and Advanced Marketing Campaigns customers get one dedicated sending IP by default. You can view any IPs attached to your account here.
- Free and Essential customers send from groups of shared IP addresses, where they group with senders of similar reputation and deliverability. Shared IPs addresses that these accounts send from can change without notice as your reputation changes, or as we make changes to IP groups to improve deliverability. In these cases, you will not be able to view your shared sending IP addresses from within your account.
How many dedicated IPs should I have?
Please see our document on suggested IP allocation based on volume.
Adding an additional dedicated IP address
You can purchase an additional dedicated IP Address from the IP Addresses Settings page or from your Plan & Billing Details page.
To add an additional dedicated IP Address:
- In the left navigation, select Settings and then click IP Addresses. Here you'll see a list of your current d IPs. Your IPs in warmup will have a 'warmup' label.
- Click Add an IP Address.
- Select the number of IP addresses you would like to purchase.
Only the Parent account or Teammates with either Billing or Admin permissions can purchase and add dedicated IPs.
Under "Additional Options" you will find the following options:
- Use automated IP warmup: SendGrid will gradually increase the amount of email sent over this IP. Note: It is best practice to warm an IP address over time before sending fully over that IP address. When using automated warmup, you must have at least one other warm IP that can handle the overflow traffic from the IP in warmup.
- Allow my parent account to send mail using these IP addresses: You want your parent account to be able to send over this IP. If you are assigning this IP to a subuser and only want that subuser to have permission to send on this IP, leave this box unchecked.
- Allow my subusers to send mail using these IP addresses: Select any subusers you would like to send on this IP address.
After purchasing your IP, we strongly encourage you to set up reverse DNS. For more information about setting up reverse DNS, see How to set up reverse DNS.
Additional IPs cost an extra $30 per additional IP per month. You may add 1 new IP address to your account per month through the user interface. For the addition of more than 1 IP address per month, please contact our support team.
Reputation Monitoring for dedicated IP Accounts
Twilio SendGrid does not offer dedicated IP address reputation monitoring as a service. We do not manage the reputation of your dedicated IP address since your mail only sends via your dedicated IP. This means that you have ultimate control over the content that is being sent out and therefore are responsible for monitoring and maintaining its reputation and listing status. However, many services can help you maintain your IP’s reputation.
The following are some third party tools available to assist you in maintaining your reputation:
In addition, SendGrid offers Expert Services services to Pro and Premier accounts that can help with deliverability and onboarding. Services include how to maintain/improve domain and IP reputation, reviewing message content, dedicated IP configuration, and creating a custom IP warmup plan to name a few.

Assigning a dedicated IP address to a subuser
Subusers cannot set up and add reverse DNS to their own dedicated IPs, but you can set it up for them and assign it to them. You can add a dedicated IP to a subuser when you create the subuser, or in the subuser management page.
Before you begin
You need to have a subuser, and a dedicated IP address you want to assign the subuser.
To assign a dedicated IP to a pre-existing subuser:
- Navigate to Settings and select IP Addresses.
- Find and select the IP address you wish to add any of your subusers to, and then hover over the action menu. Click the pencil icon that says Edit.
- Select the Choose the Subusers field and then click on any of the subusers you want to add from the dropdown menu to add them to the specified IP address.
- Select Save.
