How this service works
Is the domain's email hosted by titan? Looks up the MX records (Cloudflare DoH) and matches them against titan'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 Titan, along with the full list of MX hosts retrieved via Cloudflare DNS-over-HTTPS and the specific MX records that matched Titan's known mail-exchanger patterns.
Example use cases
Sales prospecting email platform detection
“Before I reach out to leads from this list, can you check if example.com is using Titan for their email? I want to tailor my pitch to their current email provider.”
Pre-migration email host verification
“We're planning to migrate our client's domain clientco.com to a new email provider — can you confirm whether they're currently on Titan by checking their MX records?”
Deliverability audit for Titan users
“I'm auditing email deliverability for our partners — can you check if partnerdomain.com is hosted on Titan and show me which MX records matched?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/hosted-by/titan?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to determine specifically whether a domain is hosted by Titan (not just any email provider). It is purpose-built for Titan detection using MX record pattern matching via Cloudflare DoH, making it more reliable than generic DNS tools. Choose this over a generic MX lookup when your workflow requires confirmed Titan-or-not answers for deliverability audits, sales targeting, or migration planning.
Side effects
- Domain has no MX records — returns no match with empty MX list
- Invalid or non-existent domain — DNS lookup fails or returns error
- Cloudflare DoH is temporarily unavailable — lookup fails with upstream error
- Domain uses Titan via a non-standard MX alias not in pattern list — false negative possible
- Missing or malformed query parameter — returns validation error
