It&#8217;s more than just a tool; it&#8217;s the primary conduit for business operations, customer engagement, and professional correspondence. The ubiquity of email in corporate communications is unparalleled, offering immediacy, versatility, and global reach. Whether it&#8217;s internal discussions, client negotiations, or marketing campaigns, emails play a pivotal role in driving business processes and strategies. This extensive reliance on email underscores the need for robust security measures to safeguard against cyber threats.<\/span><\/p><div id=\"ez-toc-container\" class=\"ez-toc-v2_0_84 ez-toc-wrap-center counter-hierarchy ez-toc-counter ez-toc-light-blue ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #414141;color:#414141\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #414141;color:#414141\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#Adhering_to_the_New_DMARC_Guidelines\" >Adhering to the New DMARC Guidelines<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#What_are_SPF_and_DKIM\" >What are SPF and DKIM?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#Why_do_Organizations_Need_SPF_and_DKIM\" >Why do Organizations Need SPF and DKIM?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#What_are_SPF_and_DKIM_Records\" >What are SPF and DKIM Records?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#How_to_Check_SPF_and_DKIM_Records\" >How to Check SPF and DKIM Records?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#What_is_Domain_Alignment\" >What is Domain Alignment?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#Why_SPF_and_DKIM_are_Not_Enough_For_Securing_Emails\" >Why SPF and DKIM are Not Enough For Securing Emails?<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#Book_a_Free_Demo_Call_with_Our_People_Security_Expert\" >Book a Free Demo Call with Our People Security Expert<\/a><ul class='ez-toc-list-level-4' ><li class='ez-toc-heading-level-4'><a class=\"ez-toc-link ez-toc-heading-9\" href=\"https:\/\/threatcop.com\/blog\/spf-and-dkim\/#Enter_your_details\" >Enter your details<\/a><\/li><\/ul><\/li><\/ul><\/li><\/ul><\/nav><\/div>\n\n<p style=\"text-align: justify;\"><span style=\"font-weight: 400; color: #000000;\">If either of these protocols is not present, then it is quite likely that domain spoofing or email spoofing can be done. The absence of these protocols will give threat actors an upper hand in creating malicious email domains and impersonating your organization to land a cyber attack. Apart from preventing attacks, the implementation of these protocols increases an email domain\u2019s reputation, resulting in higher email deliverability.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Adhering_to_the_New_DMARC_Guidelines\"><\/span><b>Adhering to the New DMARC Guidelines<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400; color: #000000;\">For bulk email senders, adhering to the DMARC (Domain-based Message Authentication, Reporting &amp; Conformance) guidelines, as per the new standards set by major email service providers, has become indispensable. Effective from February 2024, these guidelines mandate that bulk emailers implement stringent authentication measures, including DMARC, along with SPF and DKIM. The integration of DMARC is a critical step towards ensuring that emails are not only authenticated but also aligned with the best practices for email security. This compliance not only protects the integrity of email communication but also plays a vital role in preserving the trust and confidence of customers and subscribers in the digital communication ecosystem.<\/span><\/p>\n\n<style type=\"text\/css\">\n      @media print, screen and (max-width: 63.99875em){\n      .tnp-submit\n      width: 48%;\n      }\n      .wp-block-tnp-minimal{\n      padding: 20px;\n      }\n      .blog_para\n      margin-top: 4px !important;\n      line-height: 25px !important;\n      font-size: 15px !important;\n      }\n\n      }\n      .blog_para{\n      font-family: jost,sans-serif;\n      margin-top: 14px;\n      margin-bottom: 30px;\n      color: #fff;\n      font-size: 15px !important;\n      color: black !important;\n\n      }\n\n      .wp-block-tnp-minimal{\n      padding:20px;\n      border: 1px solid grey;\n      }\n\n      .tnp-submit a{\n        background: #1d58c7!important;\n    border-radius: 5px!important;\n    text-transform: inherit!important;\n    padding: 8px 25px!important;\n    font-weight: 600!important;\n    color: #fff!important;\n    width: 30%!important;\n    border: none;\n      }\n\n      .blog_get{\n      font-size: 24px !important;\n      font-weight: 700;\n      padding-bottom: 0px;\n    font-family: 'Poppins' !important;\n      margin-bottom: 0px;\n      margin-top: 0px;\n      margin-bottom: 0px !important;\n      color: white;\n          line-height: 30px;\n          color: white;\n      }\n      .row{\n             display: flex;\n    flex-wrap: wrap;\n    flex-direction: row;\n    padding: 25px 0px 25px 36px;\n    align-items: center;\n\n      }\n\n.colLeft{\n         flex-basis:50%;\n    -webkit-box-flex: 0;\n    flex-grow: 0;\n    max-width: 50%;\n    color: white;\n}\n    \n .colRight{\n       flex-basis: 45%;\n    -webkit-box-flex: 0;\n    flex-grow: 0;\n    max-width: 50%;\n }\n\n.tnp-subscription-minimal{\n    float: right;\n}\n<\/style>\n<div style=\"max-width: 741px; margin: 0 auto; background-image: url('https:\/\/awareness.threatcop.ai\/marketing\/linkedinlowerbanner.webp'); background-repeat: no-repeat; background-size: cover; background-position: center; \">\n<div class=\"row\">\n<div class=\"colLeft\">\n<p class=\"blog_get\" style=\"font-family: 'Poppins' !important; color: white !important\">Subscribe to Our Newsletter On Linkedin<\/p>\n<p class=\"blog_para\" style=\"font-size: 16px;font-family: 'Poppins' !important; color: white !important; margin-top: 10px; margin-bottom: 28px;line-height: 25px;\">Sign up to Stay Tuned with the Latest Cyber Security News and Updates<\/p>\n\n<div>\n<div class=\"tnp\" style=\"margin-bottom: 10px;\">\n            <form action=\"https:\/\/threatcop.com\/newsletter-thank-you\" method=\"get\" target=\"_blank\">\n<div class=\"tnp-submit\">\n                  <a class=\"libutton\" href=\"https:\/\/www.linkedin.com\/build-relation\/newsletter-follow?entityUrn=7062043746430783488\" target=\"_blank\" rel=\"noopener\">Subscribe<\/a><\/div>\n<\/form><\/div>\n<\/div>\n<\/div>\n<div class=\"colRight\">\n<div>\n<div class=\"tnp tnp-subscription-minimal \">\n            <img decoding=\"async\" src=\"https:\/\/awareness.threatcop.ai\/marketing\/newsletter-icon.webp\" class=\"img-fluid\"><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_SPF_and_DKIM\"><\/span><span style=\"color: #000000;\"><b>What are SPF and DKIM?<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">SPF stands for <\/span><span style=\"color: #183994;\"><a style=\"color: #183994;\" href=\"https:\/\/kdmarc.com\/blog\/spf-an-authentication-technique-for-dmarc\/\"><b>Sender\u2019s Policy Framewor<\/b><span style=\"font-weight: 400;\">k<\/span><\/a><\/span><span style=\"font-weight: 400;\"> and DKIM stands for <\/span><span style=\"color: #183994;\"><a style=\"color: #183994;\" href=\"https:\/\/kdmarc.com\/blog\/dkim-the-advance-authentication-technique-for-dmarc\/\"><b>DomainKeys Identified Mail<\/b><\/a><\/span><span style=\"font-weight: 400;\">.

In such cases, they have to send a huge number of emails and it is quite possible that their emails could land in spam. Also, such organizations are always prone to email-based attacks such as phishing, spoofing, etc.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Having both SPF and DKIM configured provides your outbound emails with an extra layer of protection. Using two-protocol authentication is a very strong approach that will have a positive effect on email deliverability. These protocols help in building the reputation of the email domain.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_SPF_and_DKIM_Records\"><\/span><span style=\"color: #000000;\"><b>What are SPF and DKIM Records?<\/b><\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">An SPF record registers a series of information that gets stored in the DNS. These records contain a list of IP addresses that are mapped to the DNS servers. The DNS servers allocate a series of records specific to a particular domain, which becomes a medium of connection for an organization with the rest of the world.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">These SPF records contain a list of IP addresses that are associated with a respective domain of the organization. When emails are sent from an organization, the receiving server checks the IP address of the incoming emails and tallies them with the SPF record of the sender\u2019s domain. Only if it matches will the emails pass SPF authentication.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">A DKIM record is either a 1024-bit or 2048-bit stream of characters that act as a digital signature on an email. The DKIM record in DNS contains a public key. The private key is mapped on the email server. The private key is signed in the email and the public key is mapped to the domain. Both key pair serves as a medium to authorize the outbound emails.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">When a user sends emails, then the receiver domain extracts the public key from pair of keys and matches them with the domain name on the DNS.
