Questions about xn--gmai-3oa.com

Is xn--gmai-3oa.com a business email?

No. xn--gmai-3oa.com is a shared email provider, so isBusinessEmail classifies it as "personal". A business email uses a domain the company owns.

Is xn--gmai-3oa.com a free email provider?

Yes. xn--gmai-3oa.com hands out inboxes on its own domain to individuals, which is what makes an address there a personal email.

Should a B2B product accept xn--gmai-3oa.com sign-ups?

It depends on what you need. If you need a company tenant or a company to sell to, ask for a work email; if you only want real people, accept it. The b2b policy blocks personal addresses and the lenient policy allows them.

How can I tell xn--gmai-3oa.com apart from a company domain in code?

POST the address to /v1/check: shared providers come back with category "personal" and is_free_provider: true, company domains with category "business".
