How this service works
Is the domain's email hosted by forwardemail? Looks up the MX records (Cloudflare DoH) and matches them against forwardemail'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 Forward Email, along with the full list of MX hosts found via Cloudflare DNS-over-HTTPS and which specific MX hosts matched Forward Email's known mail-exchanger patterns.
Example use cases
Sales prospecting for email provider
“I'm building a list of companies that use Forward Email — can you check if acmecorp.com is hosted by forwardemail so I know whether to include them in my outreach?”
Pre-migration provider audit
“Before we start migrating our client's email, can you confirm whether clientdomain.com is currently hosted on Forward Email by checking their MX records?”
Deliverability troubleshooting check
“We're having deliverability issues with emails going to techstartup.io — can you check if their email is actually hosted by Forward Email so I know how to route around any issues?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/forwardemail?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically detect whether a specific domain uses Forward Email as its email hosting provider, particularly for sales prospecting, deliverability analysis, or pre-migration audits. Prefer it over general MX-lookup tools when you specifically need Forward Email provider detection with pattern matching already built in. Choose the single-domain version (this endpoint) when checking one domain at a time; use the bulk sibling endpoint for batch workloads.
Side effects
- Domain does not exist or has no MX records — returns no match with empty MX list
- Cloudflare DoH lookup fails or times out — DNS resolution error
- Domain provided is malformed or missing — input validation error
- Forward Email changes its MX patterns — stale pattern mismatch causing false negatives
