Email marketing is the use of emails to advertise a company's products and services while also incentivizing client loyalty. It is also a method of informing consumers on your email list about new products, promotions, and other services.
In the fiercely competitive cyber world, it is necessary that you do your marketing well but, at the same time, pivotal that you’re aware of the basic security measures to safeguard your email sending habits.
So what are these security measures and how do they keep us safe from cyberattacks?
That’s exactly what we’re here to talk about! This article will discuss the 4 important DNS records you must implement on your email sending domain to enhance email delivery.
- Reverse DNS (PTR)
- SPF (Sender Policy Framework)
- DKIM (DomainKeys Identified Mail)
- DMARC (Domain-based Message Authentication, Reporting, and Conformance)
- REVERSE DNS
A DNS query for the domain name associated with a particular IP address is known as a reverse DNS lookup. This achieves the inverse of the more widely used forward DNS lookup, which queries the DNS system for an IP address.
Reverse DNS lookups seek for a PTR (pointer) record on DNS servers. If the server doesn't have a PTR record, it won't be able to resolve a reverse lookup. PTR records include IP addresses with their segments reversed and ‘.in-addr.arpa’ appended to them.
- Sender Policy Framework (SPF)
Sender Policy Framework (SPF) is an email authentication protocol that allows domain owners to specify which email servers are permitted to send emails from their domain(s).
SPF detects fraudulent sender addresses when the email is being sent. Falsified sender claims are detected in the email's envelope, which is used when it bounces. To identify email spoofing, common phishing, and spam tactics, it must be used in conjunction with DKIM and DMARC. SPF allows the recipient mail server to verify that an email claiming to have been sent from a certain domain was delivered from an IP address permitted to do so by the domain's management.
- DomainKeys Identified Mail (DKIM)
DomainKeys Identified Mail is an email authentication system that detects fake sender names in an email, which is a tactic commonly used in phishing and email spam. DKIM allows the recipient to verify that an email claiming to be from a certain domain was indeed approved by the domain's owner.
- DMARC
DMARC (Domain-Based Message Authentication, Reporting, and Conformance) is a standard or protocol for determining whether or not an email is legitimate. It uses SPF and DKIM to determine the email's authentication status. It shows the original source of the email rather than merely the domain it claims to originate from. DMARC offers improved email delivery, superior email security, and protects your domain against spoofing attempts, phishing schemes, and impersonation assaults.

Email marketing is a tried-and-tested internet marketing tool that can reach a large proportion of addressees while also improving customer experience. However, digital marketing is getting fiercely competitive, and implementing these 4 DNS records will help you market your campaign in a way that is safe, secure, trusted, and has a wider reach.

Several problems may occur when implementing these protocols for your domain.
It is restricted, however, to identifying a forged sender claim in the email’s envelope, which is used when the email bounces.
When used in conjunction with DMARC, SPF detects email spoofing, a typical phishing scheme in which the email address or domain name of a reputable firm or trusted acquaintance is used.
This restriction helps mailbox providers use fewer resources while verifying SPF data.
If you surpass this limit, the SPF check will fail.
Each include statement in the originating SPF record and any SPF records pointed to counts toward the maximum of ten.Also Read:- How are DMARC, DKIM and SPF different from each other?You must also verify that each include statement in your SPF record is relevant and absolutely cannot be substituted by another method such as the ip4 and ip6 mechanisms.Implement ip4 and ip6 mechanismsWhen you have the opportunity, replace your include statement with the ip4 or ip6 mechanism to minimize the number of DNS lookups.
The most commonly used technical term DMARC is the abbreviation for Domain-based Message Authentication Reporting & Conformance.
It is a modus operandi that makes the use of Sender Policy Framework (SPF) and Domain Keys Identified Mail (DKIM) in order to identify the legitimacy of a message in the form of an email.
