Weekly product update: validate DNS records using the Domains API

We recently told you about our two newest APIs both in private beta: Domains and Webhooks.  We've seen a lot of interest so far and gotten some good feedback.  Thanks! If you want to try them yourself, just send an email to beta@mailgun.net with your Github handle and we'll add you. This week's product update–DNS record validation– is an improvement to the Domains API which makes it a lot more useful if you are building an application that gives your end-users the ability to whitelabel their own emails. Here's how:

Validate DNS records using the Domains API

When you set up domain in Mailgun, you're given some DNS records that allow Mailgun to send and receive email on your behalf, and track clicks and opens.  These records are displayed in the Domain detail page of your control panel (see screen shot below).

With the new Domains API, these values are also available programmatically  so that you can display the appropriate records to your clients directly through your application.

But what if you want to know if your customer has properly set up the records you provided them?  No problem.  Using the Domains API you can determine whether or not SPF, DKIM, CNAME and MX records are properly configured.  When you use the Domains API to get information about a particular domain, we'll return all DNS records, along with a status of each: valid or unknown.  Valid means just what is sounds like, the DNS record is properly configured.  Unknown, means that something isn't right.  Maybe they mistyped it, or maybe it just hasn't propagated yet.    As you troubleshoot with your customer, you can check it again to make sure the records are valid before proceeding.

That's it for this week.  To those of you in the U.S.A. , we hope you had a happy 4th of July.  Till next week!

Happy emailing,

The Mailgunners
