Start warming up an IP address



API Overview

api-overview page anchor

IP warming is the practice of gradually increasing the volume of mail sent with a dedicated IP address according to a predetermined schedule. This gradual process helps to establish a reputation with ISPs (Internet Service Providers) as a legitimate email sender.

SendGrid can automatically warm up dedicated IP addresses by limiting the amount of mail that can be sent through them per hour. The limit determined by how long the IP address has been warming up.

See the warmup schedule to learn how SendGrid limits your email traffic for IPs in warmup.

You can also choose to use Twilio SendGrid's automated IP warmup for any of your IPs from the "IP Addresses" settings menu in the Twilio SendGrid App(link takes you to an external page).
