Since February 2024 Gmail and Yahoo require SPF or DKIM from every sender, and DMARC from anyone sending in bulk; mail that fails is junked or rejected. Type your domain below. Your browser reads the public DNS records directly (through Google’s public DNS resolver) and tells you what is wrong. Nothing is sent to us unless you ask for the fix.
DKIM keys sit under a name the sending service picks (the “selector”). We try the common ones; if yours uses a custom selector it shows as “not found” even when DKIM works. The full check reads it from a real test message instead.
We check SPF (syntax, duplicates, the 10-lookup limit), DKIM for every service that sends as your domain (Google Workspace, Microsoft 365, Mailchimp, HubSpot, SendGrid and others) and DMARC (policy, alignment, a working report address). You get a one-page report with the exact DNS records to paste, then a live test: you send one message from each service and we read how the receiving server scored it.
If the re-test after the change still fails, you don’t pay. If it passes, we send a PayPal invoice for USD 49 for one domain. We never ask for your email password. See a sample report.
Prefer to pay through a marketplace with escrow? The same service is on Upwork: SPF, DKIM and DMARC fix on Upwork.
Mail Watch, USD 99 a year. SPF records break again when someone adds a new mail tool or a provider changes its own record. We re-check SPF, DKIM, DMARC, MX and your certificate every day and email you the day something changes or breaks, with the exact fix. First 30 days free; reply “watch” to any of our emails or use the form below.
DMARC enforcement, USD 149 one time. We read your DMARC reports, list every service that sends as your domain, fix alignment, then move the policy from p=none to quarantine and reject step by step. Paid after the policy is enforced and your real mail still passes. Includes one year of Mail Watch.
