SPF and DKIM are important resources to help secure different aspects of the mail flow. One of the problems left unsolved by SPF and DKIM, however, was the specification of the actions that needed to be taken at the receiving site based on the information conveyed by these protocols. Enter DMARC.
One of the first things that a responsible ESP must deal with, before starting to mail on behalf of their customers, is Reverse DNS (rDNS from now on). This is true for businesses that send out their own email, as well. This is our tutorial on how to set up rDNS.
A lot of business email senders are wondering just what Gmail's new "tabs" feature, now turned on by default for all Gmail users, means for delivery of the commercial email that they send. Will marketing email now go by default into the 'Promotions' tab, where Gmail users will probably rarely look? Will email go to the promotions folder instead of the spam folder? Just what will be the effect of Gmail tabs for email senders?
As we've talked about at length before, web-based email providers such as Gmail, Yahoo, and Hotmail, take into account the open rates and click-through rates associated with the email that you send to their users. If your rates are too low, they will start putting your email in the spam folder.

Now, if you are a legitimate sender, having a privately registered domain will hurt your email deliverability.
Anybody who sends email has seen them, in one form or another - those SMTP error codes, often returned in bounced email, such as "550 Requested action not taken: mailbox unavailable" or "550 5 2 1 mail from refused spam site." These are often in response to SMTP commands that have 'gone wrong' between your email server that sent the email, and the receiving email server that is unable to deliver it (or refuses to deliver it) for some reason. But what exactly do they mean? And why should you care? ('SMTP' stands for Simple Mail Transfer Protocol.) First, here is a list of SMTP messages and error messages, and what each message is supposed to say and mean
