Email List Verify was simple, fast, and very affordable. I had several old email lists containing addresses collected over many years, and I needed a reliable way to identify which ones were still valid before sending a reconnection email. The upload process was easy, the results were clear, and I was able to clean the entire list in one sitting. Review collected by and hosted on G2.com.

Virtually nothing. For a first-time user, I would have appreciated a little more explanation of the different result categories, but once I understood them, the process was straightforward. Review collected by and hosted on G2.com.
