Refuse Gmail, Yahoo, Outlook and other free email addresses on your forms
Block 9,000+ disposable and temporary email domains, subdomains included
Always allow or always block your own domains, and test any address first
Show your own message under the email field and see 30 days of refusals
Only accept business email addresses on your forms. It refuses Gmail, Yahoo, Outlook and other free addresses, plus disposable ones, and shows your message under the email field so visitors can switch to a work address. Made for B2B lead forms, quote and demo requests, and partner sign-ups.
No list to build: 9,000+ disposable domains, 260+ free email domains worldwide (GMX, Mail.ru, QQ, Naver, Yahoo Japan and more) and 100+ internet provider and mobile carrier domains are built in, each with its own switch. App updates keep them fresh.
Always allow a partner domain or one address, and always block a competitor or a whole ending such as .ru. Test any address to see if it passes and why, even before saving.
Keep your existing forms, no code: pick a form and the email field is found for you. The dashboard counts refusals over the last 30 days, by reason. Visitors' addresses are never stored.
The free plan protects one form with every list and rule. Pro protects all of your forms.
Good to know: it works with the current Forms app, not the legacy one. It checks the domain, not whether the inbox exists. If a check can't finish in a few seconds, the submission goes through.
