Upload an email list full of invalid emails → get a clean list!


The problem is that invalid emails bounce back when you send to them. It may lead to account suspension when bounce rate is too high. Your bounce rate should stay within 10-15% threshold. Upload your list to validate emails or clean emails you find with Snovio. Snovio can reduce your bounce rate by 91%. We will check every email address you have.

How do I export valid emails?

You will have three options:
