What each setting does

The input this example runs Email Deliverability & Domain Security Checker with. “Try this input” opens it in the console, where you can run it as-is or change any field first.

Domains, websites or email addresses domains

github.com, jane@stripe.com, https://www.bbc.co.uk/news, microsoft.com, python.org, mailchimp.com, shopify.com, nonexistent-domain-xyz-12345.com, not a domain!, github.com

One per line. Domains (scrape.ly), websites (https://www.example.com/page -> example.com) and email addresses (jane@example.com -> example.com) all work. International domain names are converted to punycode. Duplicates are checked once and not charged twice.

Reverse DNS (PTR) of web and mail servers reverseDns

Yes

PTR names of up to 5 IPv4 addresses of the domain and up to 10 mail-server addresses, and whether each name points back to the same address (forward-confirmed reverse DNS, which many receivers require from sending servers).

Default: No → this example uses Yes

  "domains": [
    "github.com",
