resolve402.dev/api/verify-email

Verify and validate an email address before sending: syntax, MX records, disposable domain, free webmail, role account. Email verification from DNS only: input an email, output a 0-100 deliverability score with its reasons, mail provider (Google, Microsoft 365, OVH...), SPF, DMARC, null MX and random-looking local part. Mailbox not tested (no SMTP: smtp_check:false, accept_all:null), so the score is capped at 90.
