Instant domain check
Get this result in your inbox, plus Out of the Void every Monday.
This checks your setup, not where your emails actually go. Your setup can pass every check and your emails can still sit in spam. The inbox audit sends your real campaign email to Gmail, Outlook and the other major providers and shows you exactly where it goes.
Inbox audit | $97
Your real campaign email, tested across Gmail, Outlook and the other major providers. You get the results, what's breaking, and how serious each problem is. No logins. No access to your accounts.
What percentage reaches the inbox, tabs and spam, provider by provider.
SPF, DKIM and DMARC checked in your DNS and confirmed in the headers of the email itself, including whether they line up with your From address.
Your domain and sending IPs against the main blocklists.
Scores from Google, Microsoft, Barracuda, SpamAssassin and Proofpoint.
Your email and your sending habits checked for what gets domains burned: tracking, links, volume, ramp-up, warm-up and list source.

Akhil V. | Domain health and deliverability audit
Charlie is prompt and competent. I hired him to fix email deliverability issues, specifically related to Google's tightening its compliance for bulk senders. He got us compliant in a few days, and we are now able to send to our entire list again without major issues.

The audit tells us exactly where to start. Apply to work with me and it's the first thing we use.
Google Workspace and Microsoft 365. You send straight from the inbox your campaigns go out from, so it works whether you use Instantly, Smartlead or something else on top.
No. The free check reads your setup. The audit tests where your real emails go, which is the part that decides whether anyone reads them.
