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.
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.
Depending on the plan you have chosen, you either have a dedicated sending IP address or you are using a shared sending IP address.
Please see our document on suggested IP allocation based on volume.
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:
Under "Additional Options" you will find the following options:
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.
Only the Parent account or Teammates with either Billing or Admin permissions can purchase and add dedicated IPs.
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.
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.
For more information on warming up an IP Address, see Warming up a dedicated IP.
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.
To assign a dedicated IP to a pre-existing subuser:
