How to validate email addresses in Python

Let’s make email address validation simple. Start by installing our client using pip installer and the following snippet:

pip install git+https://github.com/Cloudmersive/Cloudmersive.APIClient.Python.Validate.git

Then call email_full_validation and input the desired email address.

from __future__ import print_function
import time
import cloudmersive_validate_api_client
from cloudmersive_validate_api_client.rest import ApiException
from pprint import pprint
# Configure API key authorization: Apikey
configuration = cloudmersive_validate_api_client.Configuration()
configuration.api_key['Apikey'] = 'YOUR_API_KEY'
# Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
# configuration.api_key_prefix['Apikey'] = 'Bearer'
# create an instance of the API class
api_instance = cloudmersive_validate_api_client.EmailApi(cloudmersive_validate_api_client.ApiClient(configuration))
email = 'email_example' # str | Email address to validate, e.g. \"support@cloudmersive.com\".    The input is a string so be sure to enclose it in double-quotes.
try:
    # Fully validate an email address
    api_response = api_instance.email_full_validation(email)
    pprint(api_response)
except ApiException as e:
    print("Exception when calling EmailApi->email_full_validation: %s\n" % e)

The API will do the rest of the work, checking both the syntax of the email address as well as querying the server. Below you will find an example result for “support@cloudmersive.com”:

{
  "ValidAddress": true,
  "MailServerUsedForValidation": "mx.zoho.com",
  "Valid_Syntax": true,
  "Valid_Domain": true,
  "Valid_SMTP": true,
  "IsCatchallDomain": false,
  "Domain": "cloudmersive.com",
  "IsFreeEmailProvider": false,
  "IsDisposable": false
}
