How this service works
Is the domain's email hosted by barracuda? Looks up the MX records (Cloudflare DoH) and matches them against barracuda's mail-exchanger patterns, returning yes/no, the MX hosts and which matched. Provider detection for deliverability, sales and migration work. $0.01 per lookup.
Output
Returns a yes/no answer indicating whether the domain's email is hosted by Barracuda, along with the full list of MX hosts found via Cloudflare DoH and which specific MX records matched Barracuda's known mail-exchanger patterns.
Example use cases
Sales prospecting email provider detection
“I'm building a list of companies that use Barracuda for email — can you check if techcorp.com is hosted by Barracuda so I know whether to target them with our migration pitch?”
Pre-migration email infrastructure audit
“Before we start the migration project, can you confirm whether clientdomain.com currently has their email hosted by Barracuda? I need the MX records and which ones matched.”
Deliverability research for a specific domain
“I'm diagnosing deliverability issues and need to know if newsletter-target.com runs Barracuda for email — can you look up their MX records and tell me if Barracuda is their provider?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/barracuda?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need to detect Barracuda as an email hosting provider for a domain, particularly for sales intelligence, deliverability research, or pre-migration audits. It is purpose-built for Barracuda pattern matching rather than generic MX record inspection, making it more reliable than manually parsing MX records. Prefer it over general DNS lookup tools when Barracuda-specific provider detection is the explicit goal.
Side effects
- Domain does not exist or has no MX records — returns no match with empty MX host list
- DNS lookup failure via Cloudflare DoH — may return an error or inconclusive result
- Domain uses a custom or aliased MX hostname that doesn't match known Barracuda patterns — false negative possible
- Invalid or malformed domain input — likely returns an error response
