Spark Post Enterprise accounts: In some configurations, Sending Domains will be set to verified automatically when they are created, and can be used to send messages immediately.
Create a sending domain by providing a sending domain object as the POST request body.
We hope this blog will help you avoid those pitfalls and streamline your time to completion, but if you have a problem that you cannot solve using this blog you can still contact our support team or submit a support ticket on our website.
There are three ways to have your domain verified with us: approver email, approver URL and DNS TXT records.
We allow any given domain (including its subdomains) to only be used by a single customer account.
Please see our support article for additional reasons a domain might not be approved for sending.
