Domain Health Checker
Check a company domain’s HTTPS response and public MX, SPF, and DMARC setup before you rely on its website or email domain.
Domain Check Results
Review each technical signal separately and follow up on anything missing.
The domain is sent to its website host and Cloudflare’s public DNS resolver for these checks. TradeGoAI does not save the report. Technical results do not prove company legitimacy, ownership, creditworthiness, mailbox existence, or message deliverability.
How to Read the Results
Each result answers one practical question about the domain’s public technical configuration.
Shows whether the secure website responded. A blocked automated check may still need manual browser review.
MX identifies receiving mail servers. SPF publishes which systems may send mail for the domain.
DMARC publishes how receiving systems should handle messages that fail authentication checks.

Frequently Asked Questions
Understand what these public technical checks can and cannot tell you.
What does the Domain Health Checker review?
It checks whether the domain resolves publicly, whether its HTTPS website responds, and whether public MX, SPF, and DMARC records can be found.
Does a passing result prove that a company is legitimate?
No. These results describe technical domain and email configuration only. They do not verify company registration, ownership, trading history, credit, or buyer intent.
Does an MX record mean every email address exists?
No. MX records show that a domain is configured to receive email. They do not confirm a specific mailbox or guarantee that a message will be delivered.
Why might HTTPS show as unavailable?
The website may be offline, block automated requests, redirect elsewhere, use an invalid certificate, or take too long to respond. Confirm the result in your browser.
Are the domains I check saved?
The domain is used for the requested website check and public DNS lookups through Cloudflare’s resolver. TradeGoAI does not add it to a lead list or save the report.
