How this service works
Does office@<domain> look deliverable? Builds the office@ address for the domain you give and runs the verifier: syntax, MX presence, mail provider, disposable/free-provider flags, SPF/DMARC presence and a deliverable/risky/no verdict with the reason (mailbox existence is not probed). Fast way to find a working office contact. $0.01 per check.
Output
Returns a deliverability verdict (deliverable, risky, or no) with a reason, along with MX record presence, identified mail provider name, flags for disposable and free-provider addresses, and SPF/DMARC presence — all for the office@ address of the supplied domain. Mailbox existence is not probed.
Example use cases
Pre-send contact validation for outreach
“Before I send our partnership pitch, check if office@techstartup.io is actually deliverable — I need to know if MX records exist, whether it's a legit mail provider, and if SPF or DMARC are set up.”
Qualify inbound leads by domain
“A lead just signed up with the domain growthco.com — can you check whether their office@ address looks legitimate and deliverable, or if it's a free or disposable provider?”
Build a verified contact list for cold email
“I'm building a list of company contacts — can you verify that office@bluefinancial.com is a real, deliverable address with proper MX records before I add it to my outreach campaign?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/email/role/officeWhen to prefer
Use this endpoint when you need a fast, low-cost check on whether the standard office@ role address for a domain is reachable, without actually sending an email. Ideal for pre-qualifying business contacts, enriching CRM data, or validating leads at scale. Prefer this over generic email verifiers when you specifically need the office@ role address and want SPF/DMARC context alongside deliverability.
Side effects
- Domain does not exist or has no MX records — verdict returned as 'no' with reason
- Invalid domain format supplied — syntax error returned
- Domain uses a disposable or free-provider mail service — flagged accordingly with risky or no verdict
- Transient DNS lookup failure — may return an error or retry-required response
- Rate limiting or payment failure at $0.01 per call — HTTP 402 returned
