first<\/li>\n\n\n\n<li>Then you go for the sender&#8217;s reputation<\/li>\n\n\n\n<li>Then the content and sending patterns<\/li>\n<\/ol>\n\n\n\n<p>Your audit should follow the same sequence \u2014 fixing authentication won&#8217;t help if your domain is already blacklisted. This checklist works for email marketers, cold emailers, SaaS teams, agencies, and e-commerce brands. If you send email at any meaningful volume, you need this audit.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Email authentication checklist<\/h2>\n\n\n\n<p>Authentication is the foundation. <a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/gmail-and-yahoo-bulk-sender-requirements\/\">Gmail&#8217;s February 2024 sender requirements<\/a> made SPF, DKIM, and DMARC mandatory for bulk senders. Without proper authentication, inbox providers treat your emails as potentially fraudulent, put them in the spam folder, or outright reject them.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">SPF record verification<\/h3>\n\n\n\n<p>SPF specifies which IP addresses are authorized to send email on behalf of your domain. When an email arrives, the receiving server checks your SPF record to verify that the sending server is authorized.<\/p>\n\n\n\n<p>\u2610 <a href=\"https:\/\/emailwarmup.com\/spf-lookup\" target=\"_blank\" rel=\"noreferrer noopener\">Check if the SPF record exists<\/a> and is published in DNS<br>\u2610 All legitimate sending sources are included<br>\u2610 Record contains 10 or fewer DNS lookups (the hard limit)<br>\u2610 No syntax errors or duplicate entries \u2610 Record ends with -all or ~all, not +all<\/p>\n\n\n\n<p>Verify your <a href=\"https:\/\/emailwarmup.com\/blog\/email-authentication\/spf-record\/\">SPF record<\/a> using Google Admin Toolbox or MxToolbox.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DKIM configuration check<\/h3>\n\n\n\n<p>DKIM adds a cryptographic signature to your email headers, proving the message hasn&#8217;t been altered and confirming your domain takes responsibility for the email.<\/p>\n\n\n\n<p>\u2610 DKIM signing is enabled for all sending sources<br>\u2610 Key size is at least 1024 bits (2048 bits recommended)<br>\u2610 DKIM record is published correctly in DNS<br>\u2610 Signature alignment matches your From domain<\/p>\n\n\n\n<p>If you&#8217;re seeing <a href=\"https:\/\/emailwarmup.com\/blog\/email-authentication\/dkim-fail\/\" target=\"_blank\" rel=\"noreferrer noopener\">DKIM failures<\/a>, the problem is usually a mismatch between your DNS record and your email provider&#8217;s signing configuration.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">DMARC policy setup<\/h3>\n\n\n\n<p><a href=\"https:\/\/emailwarmup.com\/blog\/email-authentication\/fix-dmarc-quarantine-or-reject-policy-not-enabled\/\" target=\"_blank\" rel=\"noreferrer noopener\">DMARC<\/a> tells inbox providers what to do when emails fail SPF and DKIM checks. It also generates reports showing who&#8217;s sending email using your domain \u2014 including unauthorized senders.<\/p>\n\n\n\n<p>\u2610 DMARC record is published in DNS<br>\u2610 Policy is set appropriately (p=none for monitoring, p=quarantine or p=reject for enforcement)<br>\u2610 Reporting addresses are configured<br>\u2610 SPF and DKIM alignment is passing<br>\u2610 You&#8217;re actually <a href=\"https:\/\/emailwarmup.com\/blog\/email-authentication\/how-to-read-dmarc-reports\/\">reading your DMARC reports<\/a><\/p>\n\n\n\n<p>Most senders start with p=none to monitor, then move to p=quarantine after confirming legitimate sources pass authentication.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">ARC for forwarded emails<\/h3>\n\n\n\n<p>ARC (Authenticated Received Chain) preserves authentication results when emails are forwarded through mailing lists or third-party services.&nbsp;<\/p>\n\n\n\n<p>Without <strong>ARC<\/strong>, forwarded emails often fail SPF and DKIM checks even when the original message was properly authenticated.<\/p>\n\n\n\n<p>\u2610 ARC headers are being added by forwarding services you control<br>\u2610 You understand which of your emails get forwarded (mailing lists, group aliases, forwarding rules)<br>\u2610 Authentication failures from forwarded mail are identified separately in your DMARC reports<\/p>\n\n\n\n<p>This is optional for most senders, but it&#8217;s worth understanding if you&#8217;re seeing authentication failures you can&#8217;t explain.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Reverse DNS (PTR) record<\/h3>\n\n\n\n<p><strong>Reverse DNS<\/strong> maps your sending IP address back to a hostname. Inbox providers check this to verify your <a href=\"https:\/\/emailwarmup.com\/blog\/email-authentication\/email-infrastructure\/\" target=\"_blank\" rel=\"noreferrer noopener\">sending infrastructure<\/a> is legitimate (spammers rarely bother setting up proper reverse DNS).<\/p>\n\n\n\n<p>\u2610 PTR record exists for your sending IP<br>\u2610 PTR hostname resolves back to the same IP (forward-confirmed reverse DNS)<br>\u2610 Hostname matches or relates to your sending domain<\/p>\n\n\n\n<p>If you&#8217;re using a shared sending service, they handle this. If you&#8217;re on dedicated IPs, verify it&#8217;s configured correctly.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Domain and IP reputation checklist<\/h2>\n\n\n\n<p><a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/sender-reputation\/\">Sender reputation<\/a> is what inbox providers remember about your sending history.\u00a0<\/p>\n\n\n\n<p>New domains have no reputation (almost as bad as negative). Domains that sent spam have a negative reputation, requiring weeks to repair. Build a positive reputation through consistent, engagement-generating emails.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Domain age and history<\/h3>\n\n\n\n<p>Inbox providers don&#8217;t trust new domains. If your sending domain is less than 30 days old, expect deliverability problems regardless of how good your authentication and content are.<\/p>\n\n\n\n<p>\u2610 Sending domain is at least 30 days old (90+ days is better)<br>\u2610 Domain has some sending history before high-volume campaigns<br>\u2610 No previous owners used the domain for spam (check the domain history if you bought it recently)<br>\u2610 Separate domains exist for marketing\/cold email vs. transactional sends (protecting your main domain)<\/p>\n\n\n\n<p>If you&#8217;re starting cold email campaigns, set up a separate domain specifically for outbound. This protects your primary domain&#8217;s reputation if something goes wrong.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">IP reputation assessment<\/h3>\n\n\n\n<p>Your sending IP&#8217;s reputation matters more on dedicated infrastructure, less on shared IPs where the provider manages reputation across all senders.<\/p>\n\n\n\n<p>\u2610 Sending IP is not on any major email blacklists<br>\u2610 IP reputation is &#8220;Good&#8221; or &#8220;Medium&#8221; in Cisco Talos<br>\u2610 No recent spam complaints associated with the IP<br>\u2610 Sending volume is consistent<\/p>\n\n\n\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\">Check IP reputation by taking an&nbsp;<a href=\"https:\/\/emailwarmup.com\/email-deliverability-test\" target=\"_blank\">email deliverability test<\/a>&nbsp;or using MxToolbox.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Blacklist monitoring<\/h3>\n\n\n\n<p><a href=\"https:\/\/emailwarmup.com\/blog\/what-is-an-email-blacklist\/\" target=\"_blank\" rel=\"noreferrer noopener\">Email blacklists<\/a> are databases of IPs and domains known to send spam. Landing on a major list (Spamhaus, Barracuda, URIBL) can tank deliverability overnight.<\/p>\n\n\n\n<p>\u2610 Domain is not listed on any major blacklists<br>\u2610 Sending IPs are not blacklisted<br>\u2610 Monitoring alerts are configured<br>\u2610 You have a process for <a href=\"https:\/\/emailwarmup.com\/blog\/email-blacklist\/email-blacklist-removal\/\" target=\"_blank\" rel=\"noreferrer noopener\">blacklist removal<\/a> if needed<\/p>\n\n\n\n<p>EmailWarmup.com and MxToolbox offer free blacklist monitoring across multiple lists.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Email warmup status<\/h3>\n\n\n\n<p>New email accounts and domains need gradual volume increases before high-volume sending. Jumping straight to thousands of emails per day triggers spam filters.<\/p>\n\n\n\n<p>\u2610 New accounts have completed at least 14 days of warmup<br>\u2610 Warmup started at 10-20 emails per day and increased gradually<br>\u2610 Warmup emails generated real engagement (opens, replies)<br>\u2610 Warmup continues running during campaigns<br>\u2610 Different mailboxes are used for different campaign types<\/p>\n\n\n\n<p>Understanding <a href=\"https:\/\/emailwarmup.com\/blog\/email-warmup-guide\/what-is-email-warmup\/\">what email warmup is<\/a> and following a proper <strong>warmup schedule<\/strong> prevents months of deliverability problems.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Email list quality and hygiene checklist<\/h2>\n\n\n\n<p>List quality directly impacts sender reputation \u2014 high bounce rates signal purchased or scraped lists. High spam complaints signal unwanted emails. Both destroy deliverability faster than almost any other factor.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Email verification<\/h3>\n\n\n\n<p>Invalid email addresses cause hard bounces, which damage the sender&#8217;s reputation immediately. That&#8217;s why <a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/email-list-hygiene\/\">list hygiene<\/a> is a <em>must<\/em>!<\/p>\n\n\n\n<p>\u2610 All email addresses have been verified using an <a href=\"https:\/\/www.emailwarmup.com\/email-validation-api\" target=\"_blank\" rel=\"noreferrer noopener\">email validation API<\/a><br>\u2610 Hard bounces are removed immediately after each send<br>\u2610 Catch-all domains are flagged and treated carefully<br>\u2610 Role addresses (info@, sales@) are minimized<br>\u2610 Disposable email addresses are removed<\/p>\n\n\n\n<p>Verification should happen before the first send and periodically afterward.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Bounce rate monitoring<\/h3>\n\n\n\n<p><a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/email-bounce-rate\/\" target=\"_blank\" rel=\"noreferrer noopener\">Email bounce rate<\/a> is one of the primary signals inbox providers use to judge list quality. High bounce rates suggest you&#8217;re not maintaining your list \u2014 or worse, that you&#8217;re sending to addresses you shouldn&#8217;t have.<\/p>\n\n\n\n<p>\u2610 Hard bounce rate stays below 2% per send<br>\u2610 Soft bounces are monitored, and addresses are removed after repeated failures<br>\u2610 Bounce reasons are analyzed (invalid address vs. full mailbox vs. server rejection)<br>\u2610 New list segments are tested at low volume before full sends<\/p>\n\n\n\n<p>If your bounce rate exceeds 2%, pause campaigns and clean your list before continuing. The damage from continued sending outweighs any benefit from the additional volume.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Inactive subscriber management<\/h3>\n\n\n\n<p>Sending to people who never open your emails hurts your <a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/sender-reputation\/\" target=\"_blank\" rel=\"noreferrer noopener\">email reputation<\/a>. Inbox providers track engagement, and consistently low engagement signals that your emails aren&#8217;t wanted.<\/p>\n\n\n\n<p>\u2610 Inactive subscribers are identified (no opens in the last 90-180 days)<br>\u2610 Re-engagement campaigns attempt to recover inactive subscribers<br>\u2610 Persistently inactive subscribers are suppressed or removed<br>\u2610 Engagement-based segmentation prioritizes active subscribers<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Spam trap avoidance<\/h3>\n\n\n\n<p><strong><a href=\"https:\/\/emailwarmup.com\/blog\/emails-going-to-spam\/spam-traps\/\">Spam traps<\/a><\/strong> are addresses designed to catch senders with poor list practices. Hitting one tells inbox providers you&#8217;re buying lists, scraping addresses, or not removing bounces.<\/p>\n\n\n\n<p>\u2610 No purchased or rented lists are in use<br>\u2610 All addresses came from legitimate opt-in sources<br>\u2610 Old, inactive addresses are regularly removed<br>\u2610 List building doesn&#8217;t involve scraping or harvesting<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Consent and opt-in verification<\/h3>\n\n\n\n<p>Sending to people who didn&#8217;t opt in generates spam complaints that destroy the sender&#8217;s reputation.<\/p>\n\n\n\n<p>\u2610 All recipients have explicitly opted in to receive email<br>\u2610 Opt-in source and date are recorded for each subscriber<br>\u2610 Double opt-in is used for public signup forms<br>\u2610 Consent records can be produced if challenged<\/p>\n\n\n\n<p>For cold email, the rules differ \u2014 you&#8217;re not using <a href=\"https:\/\/emailwarmup.com\/blog\/email-deliverability\/opt-in-email-marketing-for-deliverability\/\" target=\"_blank\" rel=\"noreferrer noopener\">opt-in<\/a> lists, so list quality and verification become even more critical.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Email content and formatting checklist<\/h2>\n\n\n\n<p>Content affects deliverability two ways \u2014 spam filters analyze it algorithmically, and recipients react with engagement or complaints. Engagement matters more \u2014 a well-authenticated email from a reputable sender can still land in spam if content triggers filters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Spam trigger words<\/h3>\n\n\n\n<p>Spam filters flag certain words and phrases that appear frequently in spam emails.
