- Remove Problem Emails — Identify all known "spam traps," "honeypots," and "screamers"
- Communicate — Converse with all domains, ISP, and mail servers
- Return — Receive verified and transmission-ready email addresses in real-time.

After an email address has been analyzed, AccuValid appends a result code that will appear on the output file you receive.

The codes that are appended to your list provide comprehensive yet understandable insight about each email address. Use this to make informed decisions about deploying to the respective addresses.
