IP Access Management is a security feature that allows you to control who can access your SendGrid account based on their IP address. After you allow an IP address, you can only access the SendGrid UI, API, and SMTP relay if you are connecting from an allowed IP address. Any access attempts from other IPs will be blocked. This is a powerful security tool that you can use to help prevent malicious activity on your account.
It is possible to remove your own IP address from your list of allowed addresses, thus blocking your own access to your account. While we are able to restore your access, we do require thorough proof of your identify and ownership of your account. We take the security of your account very seriously, and wish to prevent any "bad actors" from maliciously gaining access to your account.
Your current IP is clearly displayed to help prevent you from accidentally removing it from the allowed addresses.
If you do not access SendGrid via a static IP address (for example, via VPN or from a business internet service), setting up IP Access Management may result in being locked out of your SendGrid account. If you do discover that you have locked yourself out of your account, please contact SendGrid Support.
There is no limit on how many IP addresses you can allow.
There are several different ways to allow an IP address. If you navigate to the IP Access Management page under Settings, you will see a list of any currently allowed IP addresses and a list of IPs that recently attempted to access your account.
Under Recently Accessed 20 IPs, you will see a list of recent IPs that attempted to connect to your account, regardless of whether or not they are allowed addresses. You will also see some additional information about those IPs, such as the date of the first and most recent access attempt, the physical location of the IP, and the method by which they attempted to access your account.
You can allow one of these IPs by clicking the gear icon in the row of the IP you would like to allow, then clicking Add To Allowed List .
To manually allow one or more IP addresses, click + Add IP Addresses.
You can add recently accessed IPs by clicking Add to Form Below next to the IP you wish to save, or you can enter a single IP address or range of IP Addresses in the field at the bottom of the modal and then click Save.
It is possible for advanced users to use CIDR notation to allow a range of IP addresses. To do so, simply enter your routing prefix followed by a
/ and then the number of bits in your routing mask. For example:
Explaining CIDR notation is beyond the scope of this article, and we only recommend that advanced users use this notation when allowing IPs. If you are unfamiliar with CIDR notation, we recommend that you enter each IP individually when allowing a range of IPs.
To enter a range of IP addresses using a “wildcard”, simply add an asterisk to the end of the IP. For example,
25.203.44.* would include all IPs that begin with
After entering the IP addresses you would like to allow, click Save.
If you remove every IP address from your list of allowed addresses, you will again be able to log in to your account from any IP address.
