Features
Email validation
Keep addresses you collected yourself clean.
Check single addresses instantly or upload a list and get each address back with a clear reason: valid, risky or invalid.
What you get
Layered checks
Syntax, domain and mail-server records, disposable and role addresses, typo hints, and mailbox-level checks where the plan allows.
A reason for every result
Not just a score. Each address comes back with the check that decided it, so you know what to do.
Lists in, clean files out
Upload CSV or text, map the column, watch progress live and download valid, risky and invalid files separately.
Your lists stay yours
Uploads are processed for you only, kept for the retention period on your plan and then deleted.
Credits you can see
Each plan includes validation credits, you can buy packs, and usage is shown before you start a batch.
Used responsibly
Validation is for addresses you collected with consent. Our acceptable use policy prohibits purchased or scraped lists.

Questions
Do you keep my list?
Only for the number of days your plan keeps results, then it is deleted. You can delete a batch yourself at any time.
Can I validate a list I bought?
No. Our acceptable use policy requires addresses you collected yourself with permission.
What is a risky result?
The address may work but the server accepts everything, the address is a shared role mailbox, or the server didn't answer clearly. The reason is shown.
Other areas: Blacklist monitoring, SMTP and auth testing, DNS authentication, PowerMTA servers, Deliverability analytics.
