resolve-email

resolve-email

Resolve the domain of a syntactically valid email address to see if there is even a chance of deliverability. Also checks against a large list of disposable email and other junk/unwated address domains and rejects those. It also checks the email address against the (updated) zod reasonable email regex and filters out unreasonable email addresses.

npm install resolve-email

Usage

import { resolveEmail } from 'resolve-email'

// Validate the email address before passing it in here:
const results = await resolveEmail('[e-mail]')

console.log(results)
// results.emailResolves true/false
// results.mxRecords [array of mx records and priorities]
// results.error any errors that may have occurred.
