CLI tool to verify valid email addresses

Follow below steps for this to work

1. Register for a free account at either/both Never Bounce or MailboxLayer

2. Create apiKeys.js file in root of project that

   A. Contains your credentials

   B. Exports your credentials according to below format

   module.exports = {
       neverbounce: {
           username: "1234567890",
           key: "abcdefghijklmnopqrstuv"
       },
       mailboxLayer: {
           key: "abcdefghijklmnopqrstuv"
       }
   };
   

3. Run $ node check.js FILENAME SERVICECODE and wait for the results **

** Things to consider

• SERVICECODE is mbl for Mailbox Layer or nb for Never Bounce
• FILENAME should be located in /desktop and include the .csv extension => emailList.csv
• The output will be written to /desktop as FILENAME+ Results.csv => emailListResults.csv
• To authenticate with NeverBounce, make sure you include your username and key in the apiKeys.js file. Run $ node authenticate.js
• Final Example: $ node check.js emailList.csv mbl
