The Bulk Email Checker is a deliverability audit for a whole list of addresses. For each email it checks the syntax and mail server (MX), then flags disposable/temporary domains, role addresses (like info@ or admin@), and free providers (Gmail, Yahoo, Outlook), and combines everything into a simple 0–100 quality score with a clear verdict: deliverable, risky, or undeliverable. Paste up to 100 addresses and export the full audit to CSV.
This free tool by Hosting Cambodia is for anyone running email campaigns, lead lists or sign-up forms in Cambodia and beyond who wants higher inbox rates and fewer bounces. Disposable and role-based addresses are common causes of low engagement and spam complaints — catching them before you send keeps your list healthy, your reputation strong, and your cost-per-contact down. No login, no install; it all runs in your browser.
Frequently asked questions
How is the quality score calculated?
It combines valid syntax, a working mail server (MX), and penalties for disposable domains and role addresses into a 0–100 score. 80+ is deliverable, 50–79 is risky (send with caution), below 50 is undeliverable or unsafe.
What is a disposable or role email?
A disposable email uses a temporary domain (like mailinator.com) that self-destructs — poor for real contacts. A role email (info@, sales@, admin@) points to a shared inbox rather than a person, which often means low engagement and higher complaint risk.
What's the difference between this and the Bulk Email Validator?
The Validator confirms format and mail server (a quick clean-up). The Checker goes further with disposable/role/free-provider detection and a quality score — a fuller deliverability audit before a campaign.
Can I download the audit?
Yes. Copy or export the full results (score, provider type, MX and verdict for every address) as a CSV file.
