Find out why your emails land in spam, and how to fix it. Email Health Check by MailAfiniti checks any domain's email setup in seconds. Click the icon and it checks the website you're on, or type any domain, like your own, and press Check. You get a grade from A to F and a plain-English explanation of what works and what needs fixing. Most "my emails go to spam" problems come from a missing or misconfigured DNS record. This extension finds them. WHAT IT CHECKS: - MX: can the domain receive email at all? - SPF: is the domain protected from people sending email in its name? - DKIM: are its emails digitally signed? (We check the most common DKIM selectors.) - DMARC: is there a policy that stops spoofed and phishing email? WHO IT'S FOR: - Founders and marketers working out why cold emails or newsletters go to spam - Agencies checking client domains before a campaign - IT teams verifying email DNS after a migration - Anyone who wants to know their domain is set up to reach the inbox You see the record that was found, and for a missing SPF or DMARC record you get a ready-to-copy fix you can paste into your DNS. Every problem also links to a step-by-step guide. Want a detailed report? Use the free Email Health Check on mailafiniti.com/tools/email-health-check. No account. No signup. Free. Built by MailAfiniti, business email hosting that sets up SPF, DKIM and DMARC for you, from $2 per mailbox per month. PRIVACY: When you open the extension, it reads only the domain of the tab you're on, to fill in the box. That domain, or the one you type, is sent to MailAfiniti's API to run public DNS lookups. We don't read page content, track your browsing, or store your checks. Built and maintained by MailAfiniti, the email hosting and deliverability platform built for senders who care about reaching the inbox.
