Understanding Email Verification Architecture & Gmail Technical Nuances

How DNS lookups, MX records, syntax rules, and alias patterns keep your sender score clean.

Syntax & Gmail Format Rules

Standard `@gmail.com` usernames must be 6 to 30 characters long and contain only letters, numbers, and periods. Gmail ignores periods in usernames (e.g. j.oh.n@gmail.com matches john@gmail.com) and supports plus alias tags (user+tag@gmail.com).

Real-Time DoH MX Record Lookup

Before sending mail, the engine issues DNS over HTTPS queries to verify if the receiving domain has active Mail Exchange (MX) records. Google Workspace domains use aspmx.l.google.com or smtp-in.l.google.com servers.

Risk & Disposable Detection

Role accounts (admin@, support@) and throwaway temporary mail services (tempmail, mailinator) trigger high bounce rates or spam complaints. The engine calculates a Deliverability Quality Score (0 - 100%) for each record.
