NeverBounce

NeverBounce is a simple library for validating email addresses using the NeverBounce API.

Usage

using NeverBounce;
NeverBounceClient client = new NeverBounceClient("[your API key]");
EmailValidationResult result;

result = client.Verify("[some email address]");
result = await client.VerifyAsync("[some email address]");

if (result.Valid)
{
  // success
}
else
{
  // failure
}

The EmailValidationResult object, when shown as JSON, appears as:

{
  "Time": {
    "Start": "2022-05-22T05:18:36.0598952Z",
    "End": "2022-05-22T05:18:36.9516956Z",
    "TotalMs": 891.8
  },
  "Valid": true,
  "Flags": {
    "HasDns": true,
    "HasDnsMx": true,
    "IsFreeService": true,
    "SmtpConnectable": true,
    "AllFlags": [
      "free_email_host",
      "has_dns",
      "has_dns_mx",
      "smtp_connectable",
      "has_dns"
    ]
  },
  "Raw": {
    "status": "success",
    "result": "valid",
    "flags": [
      "free_email_host",
      "has_dns",
      "has_dns_mx",
      "smtp_connectable",
      "has_dns"
    ],
    "suggested_correction": "",
    "execution_time": 166
  }
}

The following are the main components:

• Time indicates the start and end time, and the total amount of time in milliseconds taken to get a response
• Valid is a boolean indicating whether or not the address should be considered valid
• Flags indicates the flags returned by the service
• Raw is the raw response received from the server
