Output

Default output:

[e-mail] → exists

JSON output:

[
  {
    "email": "[e-mail]",
    "status": "exists"
  }
]

Possible statuses:

• exists
• does_not_exist
• unknown

Python API

from mailrecon import validate

status = validate("[e-mail]")
print(status)

Notes

• Validation is provider-specific and only works for supported domains.
• Different providers use different validation strategies. Some providers, like Yahoo, use deeper validation flows, while others may return results more directly.
• Live validation can return unknown when a provider changes behavior or blocks requests.
