What is email authentication (SPF, Sender ID and DomainKeys/DKIM) and how do I set it up?
When sending an email we let you set your own "from address" so that email will appear to be from that address. Instead of coming from This e-mail address is being protected from spambots. You need JavaScript enabled to view it , it might come from This e-mail address is being protected from spambots. You need JavaScript enabled to view it . Because of the way email was originally built, it's tough to prove if an email is actually coming from the person who claims to be sending it. Email authentication fixes this by letting you add some simple information to your domain name's DNS records that says who's allowed to send email on your behalf.
Without getting into too much of the boring, technical details, there are two main authentication standards you should support called Sender ID and DomainKeys/DKIM. What is important is that different ISP's use one or a combination of both so to get the best results we've made it as easy as possible to support both standards.
What's In It For You?
All the large ISP's like AOL, Hotmail, Yahoo! and Gmail are using email authentication as an important layer in their spam fighting arsenal. By setting up this system as an authenticated sender, you can instantly bypass certain filters, giving your campaigns a better chance of arriving in the destination inbox. Not only that, but many ISP's like Yahoo! and Hotmail will flag your email as authenticated, which helps to build trust between you and your subscribers and improves the chances of your emails being opened.
