Let’s say you have a very popular store. Your customers love receiving coupons and communications from you by email. Then a spammer sees your email address as a great opportunity to take someone’s personal information. They send an email claiming to be you, requesting updated credit card information from your customers. Now your customers are calling in, upset that their information was compromised, and they think it’s your fault. Once word gets out, no one feels confident opening your email communications. How are they to know it’s really you?

So you’ve heard a lot about this new thing called DMARC, but don’t totally understand what to do? You are at the right place! After all, at Agari we are the DMARC guys. (Someone said this to me at a conference recently. I think it deserves a t-shirt. ☺) If you take a few minutes to read on, we will help you understand why you should publish your business’ first DMARC record.
Email-service providers Google Inc., Yahoo Inc., Microsoft Corp. and AOL Inc. are backing a new effort intended to dramatically reduce "phishing" emails—which attempt to trick recipients into thinking they come from a legitimate source.

The companies—along with others such as financial-service companies Bank of America Corp., FMR LLC's Fidelity Investments and eBay Inc.'s PayPal—are hoping to create an environment that allows the recipient of an email from, say, a bank, to feel secure that it isn't a trick.
