While not the primary purpose of this security standard, it\u2019s logical for authenticated messages to have better delivery rates than non-verified emails.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Apart from <\/span><b>increasing the email deliverability rate<\/b><span style=\"font-weight: 400;\">, SPF is also helpful in preventing malicious actors from exploiting your domain name to send fraudulent emails for nefarious purposes.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">SPF, or the Sender Policy Framework, is an email authentication protocol that allows only specific IPs to send emails using a domain name. Any IP address outside the list won\u2019t reach a receiver&#8217;s mailbox.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To <\/span><a href=\"https:\/\/easydmarc.com\/blog\/how-to-create-an-spf-record\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">create an SPF record<\/span><\/a><span style=\"font-weight: 400;\">, you must first understand <\/span><a href=\"https:\/\/easydmarc.com\/blog\/how-does-an-spf-record-work\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">how SPF works<\/span><\/a><span style=\"font-weight: 400;\">. With a deeper understanding of this authentication standard, you can improve <\/span><b>email deliverability rates<\/b><span style=\"font-weight: 400;\">, promoting success in your marketing efforts<\/span><b>.<\/b><\/p>\n<p><span style=\"font-weight: 400;\">By <\/span><span style=\"font-weight: 400;\">adding an SPF record to your DNS<\/span><span style=\"font-weight: 400;\">, a recipient server can verify whether the sender\u2019s email address is registered in the SPF record. If so, the email will be reflected in the \u2018inbox.\u2019 If not, it\u2019ll be labeled as \u2018spam.\u2019 In some cases, a receiver\u2019s mailbox may completely reject such an email under suspicion of it being malicious.<\/span><\/p>\n<h2><b>Why Do You Need Sender Policy Framework?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Do you know more than 3.1 billion domain spoofing emails are sent daily? According to <\/span><a href=\"https:\/\/abnormal.ai\/threat-intelligence\/resources\/h2-2022-report-brand-impersonation-phishing\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Abnormal Intelligence<\/span><\/a><span style=\"font-weight: 400;\">, Business Email Compromise (BEC) attacks have increased by 150% yearly, with 89% of large enterprises attacked every week. The firm&#8217;s latest findings also report a 48% increase in email attacks over the past six months, 68% of which include phishing links.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These fraudulent activities are only possible due to weak email security. By spoofing your business&#8217;s name, hackers can scam victims, destroy your professional reputation, and negatively impact your overall <\/span><b>email deliverability rates<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><a href=\"https:\/\/easydmarc.com\/tools\/spf-record-generator\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">Generating an SPF record<\/span><\/a><span style=\"font-weight: 400;\"> is a practical step towards preventing phishing. Once implemented, SPF only allows authorized servers to deliver emails on your domain\u2019s behalf, thus preventing hackers from using your domain name for malicious activities.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Without SPF, receiving servers don\u2019t trust you as a legitimate sender. Most hackers don\u2019t bother setting up SPF, so doing so is an effective filtering mechanism that <\/span><b>improves email deliverability<\/b><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Adding an SPF record to your DNS<\/span><span style=\"font-weight: 400;\"> reflects your organization&#8217;s commitment toward customer protection, email security, and authentication\u2014all factors that positively impact your \u2018sender&#8217;s reputation.\u2019 SPF ensures that your legitimate messages reach their intended recipients safely and securely.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you want to know <\/span><b>how to improve the deliverability of emails<\/b><span style=\"font-weight: 400;\">, understanding the SPF mechanism is vital.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Firstly, you must specify IP addresses and\/or third parties allowed to send emails on behalf of your company\u2019s domain. This list of authorized senders is published in your SPF record, allowing email recipient servers to get information about a sender&#8217;s legitimacy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">So, when an email is sent purporting to come from your domain or on your company\u2019s behalf, a receiver can retrieve your SPF record and check the sender\u2019s address against your specified list. If something is amiss, it treats the email as spam. This happens when SPF authentication fails.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you send cold emails without SPF compliance, it\u2019s highly likely a recipient&#8217;s mailbox will block such messages as it doesn&#8217;t perceive you as a legitimate sender.<\/span><\/p>\n<h2><b>Is there an SPF Alternative?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">There\u2019s no alternative that does what the Sender Policy Framework was designed to do. While DKIM (Domain Keys Identified Mail) is a different authentication protocol, it should never be used to replace SPF.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Rather, <a href=\"https:\/\/easydmarc.com\/blog\/mynewsdesk-spf-and-dkim-configuration\/\">DKIM and SPF complement each other<\/a>, especially with the addition of DMARC or Domain-based Message Authentication, Reporting and Conformance. SPF is a vital first step on the <\/span><a href=\"https:\/\/easydmarc.com\/blog\/spf-start-your-journey-toward-dmarc-compliance\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">journey to DMARC compliance<\/span><\/a><span style=\"font-weight: 400;\">. Implementing DKIM is <\/span><a href=\"https:\/\/easydmarc.com\/blog\/dkim-another-step-to-dmarc-compliance\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">another crucial step<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<h2><b>What Does SPF Do For Deliverability?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">To <\/span><b>improve email deliverability<\/b><span style=\"font-weight: 400;\">, <\/span><a href=\"https:\/\/easydmarc.com\/tools\/spf-lookup\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">check your SPF record<\/span><\/a><span style=\"font-weight: 400;\"> and make sure it&#8217;s correctly configured.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Properly implemented, SPF (along with DKIM and DMARC) allows your mail server to deliver emails that have been verified and authenticated, which means they won\u2019t bounce back or land in the \u2018spam\u2019 folder. This tells recipient servers that you\u2019re a trusted sender, increasing your sender reputation and proving your legitimacy.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The biggest benefit is that these protocols prevent bad actors from compromising your account and sending fraudulent emails in your name.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Together, SPF, DKIM, and DMARC authenticate your emails and prove to ESPs that your approved senders are authorized to send emails on your company\u2019s behalf. Although these email authentication standards work independently, together, their benefits are multiplied as each one addresses a unique part of the email identity chain.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">EasyDMARC takes your email-sending sources management to a higher level with the help of our specialized <\/span><a href=\"https:\/\/easydmarc.com\/tools\/easy-spf\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">EasySPF<\/span><\/a><span style=\"font-weight: 400;\"> tool.
