How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object with the domain's MX, SPF, DKIM, and DMARC record details, a numeric deliverability score, the domain checked, and an array of identified issues or misconfigurations.
Example use cases
Pre-campaign deliverability check
“Before I send out my newsletter, can you audit mycompany.com's email deliverability and flag any issues with the SPF, DKIM, or DMARC setup that might cause emails to land in spam?”
Troubleshooting bounced emails
“My emails from acmecorp.com keep bouncing or going to junk — can you audit the email deliverability configuration for acmecorp.com and tell me what's misconfigured?”
Vendor email infrastructure review
“I'm evaluating a vendor at vendormail.io — can you check their domain's email authentication records and give me a deliverability score so I know if their emails are likely to reach my inbox?”
Technical details
Endpoint
GEThttps://klymax402.com/api/email-deliverability/api/auditWhen to prefer
Use this endpoint when you need a quick, all-in-one email deliverability audit covering MX, SPF, DKIM, and DMARC in a single call, especially when no separate email security API key is available and you want a scored summary with issue detection. Ideal for agents that need to diagnose email problems or validate domain email health on demand.
Side effects
- Invalid or non-existent domain returns error or empty record fields
- Domain with no DNS records may return null values for MX/SPF/DKIM/DMARC
- Network timeout if DNS lookup takes too long
- Malformed domain string (e.g. including http://) may cause query failure
