No Reliably checking whether a Gmail address is valid requires Google-side data or signup-flow probing, which Google does not expose and actively blocks. Public SMTP or DNS checks cannot confirm mailbox existence accurately.
What it would actually take: Any real version would need access to Google account-existence signals, which only Google has. Attempts to infer them through signup or SMTP probing run into rate limits, CAPTCHAs, and terms-of-service violations. The result would be unreliable and likely abusive.
