During email verification we remove any duplicates from your file, we check email syntaxes, check the email servers DNS, create an SMTP connection with the recipients' server to find out if the email accounts exist. We check if the server is set to catch all mail. We do this without sending an email to your contacts.
We also detect catch all servers and temporary email addresses, and highlight free and role email accounts.
You can upload your contacts in TXT, CSV or XLSX file and our results are available to download in a standard CSV file. If you would like you can send us files programmatically or you can program our single API into your system to verify email addresses in real time.
