How this service works
Bulk is email hosted by sendgrid: up to 20 domains in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
An ordered list of results matching the input domain list, where each item contains a boolean indicating whether the domain's email is hosted by SendGrid, a per-item error field for any lookup failures, and a top-level failure count summarizing how many items could not be resolved.
Example use cases
Sales prospect email stack enrichment
“I have a list of 15 prospect domains from our CRM — can you tell me which of them are using SendGrid to host their email? The domains are: acme.com, globex.com, initech.com, umbrella.com, soylent.com, cyberdyne.com, weyland.com, omni.com, tyrell.com, skynet.com, rekall.com, tessier.com, abstergo.com, armacham.com, and veridian.com.”
Competitive email infrastructure analysis
“We're researching which of our top 20 competitors use SendGrid for email hosting. Can you batch-check all of these domains and give me a breakdown of which ones are on SendGrid?”
Marketing tool vendor detection
“I need to audit these 12 client domains to see if any of them are sending email through SendGrid — can you run a bulk check and flag which ones come back as SendGrid-hosted, including any errors?”
Technical details
Endpoint
GEThttps://email.intel.rallylive.ca/bulk/email/hosted-by/sendgrid?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to check whether multiple domains (up to 20) host their email via SendGrid in a single API call, rather than making individual single-domain requests. Ideal for bulk data enrichment pipelines, sales intelligence workflows, or competitive analysis where you hold a list of domains and want concurrent processing with ordered results and fault tolerance per item.
Side effects
- DNS lookup failure for one or more domains returns a per-item error with the failure noted
- Invalid or malformed domain names may produce errors in the per-item error field
- Exceeding the 20-domain limit may result in a request rejection
- Network timeout or Cloudflare DoH unavailability could cause per-item or batch-level failures
- Non-existent domains with no MX records will return a negative result or error
