How this service works
Email provider detection for an address or domain: consumer webmail (Gmail, Outlook.com, Yahoo, iCloud, Proton...) versus business hosting (Google Workspace, Microsoft 365, Zoho, Proofpoint...) from the domain and its MX records. Segment contacts and pick the right deliverability playbook. $0.01 per address.
Output
Returns the detected email provider (e.g. Google Workspace, Microsoft 365, Gmail, Yahoo, Proton Mail, iCloud) and a classification of whether the email is consumer webmail or business-hosted, derived from the domain's MX records and DNS configuration.
Example use cases
Segment contacts by email tier
“I have a list of leads and I want to know which ones are using free consumer email like Gmail or Yahoo versus a proper business email setup — can you check john@startupxyz.com and tell me which category it falls into?”
Pick deliverability playbook for campaign
“Before I send our outreach campaign, can you check if hello@designstudio.io is on Google Workspace, Microsoft 365, or some other business mail host so I know which deliverability settings to use?”
Qualify inbound lead by email infrastructure
“A lead just signed up with sarah@techventures.co — can you tell me if that domain runs on a real business email provider or if it's just a free webmail address redirected to a custom domain?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/email/providerWhen to prefer
Use this endpoint when you need to classify an email address or domain by its hosting provider type — especially to segment consumer vs. business contacts or choose the right email deliverability strategy. Prefer this over a full email verification endpoint when provider identity (not deliverability status) is the primary concern. It is more specific than a generic DNS lookup because it interprets MX records in the context of known email hosting platforms.
Side effects
- Domain has no MX records — cannot determine mail provider
- Domain does not exist or is unresolvable — DNS lookup failure
- Obscure or self-hosted mail server not matched to a known provider — returns unknown
- Email address syntax is invalid — rejected before lookup
- Rate limiting or network timeout on DNS resolution
