Email is a very versatile medium that can include customer acquisition (lead or sales), retention, cross-selling, up-selling, and more. But most everything out there that provides guidelines, best-practices, and advice on the application of the channel to your marketing efforts are largely geared toward bigger businesses.

DNS Records

Technical standards through which ISPs and other mail gateway administrators can establish the true identity of an email sender. Examples of proposed authentication standards include: SPF (PO Box, AOL), Sender-ID (Microsoft), DomainKeys (Yahoo), and DKIM (Cisco and Yahoo)

SPF – SPF (Sender Policy Framework) compares an email sender’s actual IP address to a list of IP addresses authorized to send mail from that domain. This list is published in the domain’s DNS record.
