How this service works
Email normalizer: lowercases, strips plus-tags, applies provider rules (Gmail ignores dots, googlemail.com = gmail.com, outlook/hotmail/yahoo/proton/fastmail +tags) and returns a canonical form for deduplicating contact lists and detecting duplicate signups. $0.01 per address.
Output
Returns the canonical, normalized form of the input email address after applying lowercasing, plus-tag stripping, dot-insensitivity rules for Gmail, provider alias resolution (googlemail.com → gmail.com), and plus-tag rules for Outlook, Hotmail, Yahoo, Proton, and Fastmail.
Example use cases
Deduplicating signup forms
“A user just signed up with 'jane.doe+promo@googlemail.com' but I think we already have them — can you normalize that email to its canonical form so I can check if it's a duplicate in our system?”
Cleaning imported contact list
“I've got a batch of emails from a CSV import and I need to normalize 'bob.smith+tag@gmail.com' to its canonical Gmail form before I add it to our CRM — what does it look like stripped of the plus-tag and dots?”
Fraud detection for multiple accounts
“Someone may be using email variations to create multiple accounts — can you normalize 'alice+account2@hotmail.com' to its canonical Outlook form so I can check it against existing users?”
Technical details
Endpoint
GEThttps://intel.rallylive.ca/email/normalizeWhen to prefer
Use this endpoint when you need to reliably deduplicate email addresses across provider-specific variations — especially when handling Gmail dot-insensitivity, googlemail.com aliases, or plus-tag stripping across multiple providers (Outlook, Hotmail, Yahoo, Proton, Fastmail). Prefer this over simple lowercasing or regex-based stripping when accuracy across multiple email providers matters.
Side effects
- Missing or malformed email input returns an error
- Invalid email format may not be processable
- Unsupported or unknown provider may receive only basic normalization (lowercase, plus-tag strip) without provider-specific rules
- Network timeout or service unavailability returns a non-200 response
- Payment failure (insufficient funds for $0.01 USDC) blocks the call
