Questions about ac-filters.org
Is ac-filters.org a business email?
No. ac-filters.org is a shared email provider, so isBusinessEmail classifies it as "personal". A business email uses a domain the company owns.
Is ac-filters.org a free email provider?
Yes. ac-filters.org hands out inboxes on its own domain to individuals, which is what makes an address there a personal email.
Should a B2B product accept ac-filters.org 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 ac-filters.org 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".
