IP Warmup

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.

Stop warming up an IP address

DELETE /v3/ips/warmup/{ip_address}

Base url: https://api.sendgrid.com

This endpoint allows you to remove an IP address from warmup mode.

Your request will return a 204 status code if the specified IP was successfully removed from warmup mode. To retrieve details of the IP’s warmup status before removing it from warmup mode, call the "Retrieve the warmpup status for a specific IP address" endpoint.
