Clean an email list without SMTP pings: typos, disposable and dead domains

Описание и применение

Валидация списков email без SMTP‑пингов: проверка синтаксиса, MX‑записей, disposable‑доменов, ролей, опечаток и провайдеров, выдача оценок и рекомендаций.

Задача

Outbound campaigns risk sending to invalid or disposable email addresses, causing bounces and IP blocklisting.

Результат

The validator identifies syntax errors, non‑existent domains, null MX, disposable domains, role addresses, typos, and mail provider, assigning a 0–100 score and a clear reason. It avoids SMTP pings, preventing IP blocklisting and reducing costs.

Рабочий процесс

• Collect raw email list from form, CRM export, or scraper
• Run Email List Cleaner – Bulk Email Validator on the list
• Review verdicts: keep valid, fix risky, remove invalid
• Export VALID_EMAILS and VALID_AND_RISKY_EMAILS for sending tool
• Optionally integrate with scraper pipeline to validate immediately

Доказательства

Most "email verifier" tools answer this by connecting to the recipient's mail server and pretending to send a message (an SMTP "ping"). That used to work. Today it mostly does not: Gmail, Outlook, Yahoo and the big corporate gateways either block those probes or answer "yes" to every address, and the IP doing the probing can end up on a blocklist.

For every address, Email List Cleaner – Bulk Email Validator checks: Syntax per RFC 5321/5322, MX records over DNS-over-HTTPS, disposable domains, role/no‑reply addresses, typos, mail provider.

Источник

Each address gets a verdict, a 0–100 score and a reason in plain English: valid, risky, invalid, unknown.

The typo case is the one that saves real leads: "[email protected]" → "risky" with didYouMean "[email protected]".

Besides the table, every run saves two plain-text records, VALID_EMAILS and VALID_AND_RISKY_EMAILS, one address per line, ready to paste into your sending tool.
