How this service works
Does the domain carry a sendgrid domain-verification TXT record? Reads the apex TXT records (Cloudflare DoH) and reports whether the sendgrid ownership token is present and the token value (truncated). A present token usually means the company uses sendgrid's product; absence means not verified there. $0.01 per lookup.
Output
Returns a boolean indicating whether a SendGrid domain verification TXT record is present at the domain's apex, along with a truncated version of the ownership token value if found. Absence means the domain is not verified through SendGrid's DNS ownership flow.
Example use cases
Email vendor due diligence research
“I'm researching a prospective partner — can you check if techcorp.io has a SendGrid domain verification TXT record set up? I want to know if they use SendGrid for sending email.”
Competitive email stack intelligence
“Can you tell me whether stripe.com has a SendGrid ownership token in their DNS? I'm mapping out which fintech companies rely on SendGrid.”
Pre-outreach email infrastructure check
“Before I cold-email the team at startup.co, can you verify if their domain has a SendGrid TXT record in DNS? I want to know what email infrastructure they're running.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/verification/sendgrid?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically determine whether a specific domain has completed SendGrid domain verification, as evidence that the organization uses SendGrid for email sending. It is ideal for email stack intelligence, vendor research, lead enrichment, or competitive analysis. Prefer this over generic DNS TXT lookups if you specifically want a structured yes/no answer about SendGrid usage with the token value surfaced.
Side effects
- Domain does not exist or has no TXT records — returns not found or empty result
- DNS resolution failure via Cloudflare DoH — transient network error
- Malformed domain input — request may fail or return no results
- SendGrid token present but query rate limit exceeded — payment or quota error
- Domain uses a subdomain-specific SendGrid setup not visible at the apex — may report false negative
