If you have a dedicated IP, you can instruct your clients or recipients to whitelist just that IP. If you don’t have a dedicated IP, though, your emails go through our shared IP range. This range of shared IPs is continuously updated as we add more servers for sending.
Whitelisting by IP is not recommended because Netcore Email API’s shared IPs may change without notice, and the recipient would be whitelisting all mail from Netcore Email API.
