Send additional parameters to Postmark

Raven will send the fields present in the Email template to Postmark by default. Additionally, you can send “cc”, “bcc”, “From Name”, “Reply-to” fields in the Send Event API. This will override the fields added in the Integration. Please check our Override doc here.

IP Whitelisting

You can control access to Postmark by specifying Raven’s IP address, or make sure Raven’s IP addresses are not blocked.
