It adds professionalism and builds trust with your audience, but simply setting up email isn&#8217;t enough.

Even if your email appears to work fine, it could still be missing critical authentication settings. Without SPF, DKIM, and DMARC, your emails are:<\/p>\n<ul class=\"list-bullet1\">\n<li class=\"ace-line ace-line old-record-id-FeqpdsAieoZGqVxbeaNlReR0gkc\" data-list=\"bullet\">Easier to spoof<\/li>\n<li class=\"ace-line ace-line old-record-id-JoMTd6oxPoKnlbxZjAellIs8gnc\" data-list=\"bullet\">More likely to be flagged as spam<\/li>\n<li class=\"ace-line ace-line old-record-id-UI5mdWTeBoFEc2xXugWl6Zbugxc\" data-list=\"bullet\">Lacking credibility with receiving mail servers<\/li>\n<\/ul>\n<div data-page-id=\"JOhRdTHNHonTPSxBY28lg3PdgLb\" data-lark-html-role=\"root\" data-docx-has-block-data=\"false\">\n<h2 class=\"heading-2 ace-line old-record-id-W8CBd4Gdio9DZoxr9xul6lH4gAf\"><strong>The Three Essentials for Email Security<\/strong><\/h2>\n<h3><strong>1. SPF (Sender Policy Framework)<\/strong><\/h3>\n<div data-page-id=\"JOhRdTHNHonTPSxBY28lg3PdgLb\" data-lark-html-role=\"root\" data-docx-has-block-data=\"false\">\n<p class=\"ace-line ace-line old-record-id-JswrdOCXxoWE9pxIW18lIrsFgrc\"><strong>What it does:<\/strong> <a href=\"https:\/\/support.exabytes.sg\/en\/support\/solutions\/articles\/14000038370-spf-sender-policy-framework-\" data-lark-is-custom=\"true\" rel=\"noopener\">SPF<\/a> tells email servers which servers are allowed to send email on behalf of your domain.<\/p>\n<p class=\"ace-line ace-line old-record-id-ARw6d3A6TouiF0xUNThlfFOIgCg\"><strong>Why it matters:<\/strong> Without SPF, <em>anyone<\/em> can pretend to be you \u2014 a tactic known as email spoofing. A valid SPF record helps receiving servers verify your identity and improves your chances of reaching the inbox.<\/p>\n<p class=\"ace-line ace-line old-record-id-WzlEd5JCOosrtxx8KzKlOpjhg0d\"><strong>Example:<\/strong> If you use Google Workspace, your SPF record should include Google\u2019s mail servers. Do take note \u2014 Google doesn\u2019t set this up for you. You\u2019ll need to manually add it to your domain\u2019s DNS settings.<\/p>\n<p class=\"ace-line ace-line old-record-id-HLHJdvbecogvjLxks38loZOjgsd\">Click <a href=\"https:\/\/support.exabytes.sg\/en\/support\/solutions\/articles\/14000031649-how-to-verify-if-spf-record-is-setup-correctly\" data-lark-is-custom=\"true\" rel=\"noopener\">here<\/a> to know how to verify if your SPF record is set up correctly.<\/p>\n<h3><strong>2. DKIM (DomainKeys Identifies Mail)<\/strong><\/h3>\n<div data-page-id=\"JOhRdTHNHonTPSxBY28lg3PdgLb\" data-lark-html-role=\"root\" data-docx-has-block-data=\"false\">\n<p class=\"ace-line ace-line old-record-id-PFSYdWcx5oQP1BxFoKClrglkgCf\"><strong>What it does:<\/strong> DKIM attaches a digital signature to each outgoing email, proving the message hasn\u2019t been altered during transit.<\/p>\n<p class=\"ace-line ace-line old-record-id-WIKYduLIzoAKs9xHBc0lCnO0gNf\"><strong>Why it matters:<\/strong> Think of it like a tamper-proof seal. Without DKIM, your messages could be intercepted and modified without your knowledge. Most email services generate the DKIM key for you, but you must still add it to your DNS manually.<\/p>\n<p class=\"ace-line ace-line old-record-id-G8HQdUeLUobguxx0pb9lnlFxgod\">Click <a href=\"https:\/\/support.exabytes.sg\/en\/support\/solutions\/articles\/14000122096-how-to-add-dkim-key-in-smartermail-to-dns-zone\" data-lark-is-custom=\"true\" rel=\"noopener\">here<\/a> to know how to add DKIM.<\/p>\n<h3><strong>3.
