How this service works
Garantizamos soberanía digital mediante ejecución autónoma. Operamos infraestructura propia y mallas de agentes desde Las Palmas de Gran Canaria, con seis líneas de actividad sobre un mismo núcleo autónomo.
Output
Returns a JSON object with the domain's MX records array, parsed SPF/DKIM/DMARC objects, a numeric deliverability score (0–100), a verdict string (e.g. 'good'), and an array of actionable recommendations to improve email deliverability.
Example use cases
Pre-send campaign deliverability check
“Before I send our newsletter campaign, can you check the deliverability score and DNS records for mailchimp.mycompany.com and tell me if anything needs fixing?”
Diagnose emails landing in spam
“Our transactional emails from acmecorp.com keep ending up in spam — can you audit the MX, SPF, DKIM, and DMARC setup and give me a verdict on what's wrong?”
New domain email setup validation
“I just set up email on startupbrand.io — can you check whether the deliverability configuration is correct and give me a score along with any recommendations?”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/deliverabilityWhen to prefer
Choose this endpoint when you need a comprehensive, single-call audit of all major email deliverability DNS records (MX, SPF, DKIM, DMARC) for a domain, along with a scored verdict and prioritized recommendations, rather than querying individual DNS record types separately.
Side effects
- Invalid or non-existent domain returns an error or empty record sets
- DNS lookup timeouts for domains with slow resolvers
- Missing or misconfigured DNS records may return null/empty objects for SPF/DKIM/DMARC rather than an error
- Rate limiting or payment failure returns HTTP 402
