Get a Clean List in 3 Easy Steps
Stop hitting 'send' and praying. Here's how we get your list ready for outreach.
1. Upload Your List
Got a big outreach list? Just drag and drop your CSV or TXT file into our simple dashboard. Easy.
2. We Clean & Verify
Here's where we work our magic. We check every email for typos, dead domains, spam traps, and fakes. We even do a 'live' check (SMTP) to see if the inbox is real.
3. Download Your Clean List
Download your clean list. You'll see exactly which emails are 'Valid' (safe to send) and which are 'Invalid' (delete these!). Now you can send your campaign without worrying about bounces.

Common Questions
Valinbox is a simple tool to clean your email lists. You upload a list of emails, and we tell you which ones are good and which ones are bad (bounces, fakes, etc.). This helps you get more emails into the inbox.
Our main difference is fairness: **We never charge for 'unknown' results.** If we can't tell you 100% if an email is good or bad, you don't pay for that check. Most others still charge you.
No. All purchased credits are pay-as-you-go and **never expire**. You can use them today, next month, or next year.
We keep it simple:
- **Valid** – Safe to send.
- **Invalid** – Non-existent, syntax error, or disabled. (Delete these!)
- **Catch-All** – Domain accepts all mail; sending is risky.
- **Disposable** – Temporary, one-time use email.
- **Unknown** – Server didn't respond. (You are not charged for these).
Yes. Your data is encrypted. We are GDPR/CCPA compliant. We *never* share or sell your lists. They are automatically deleted after you're done.
