What the widget does

Checks as people typeEach email is checked when the visitor leaves the field, before the form is sent.

Fixes typosgmial.com, yaho.com and other common mistakes get a one-click "Did you mean" suggestion.

Stops fake sign-upsChoose what to block: addresses that do not exist, disposable and toxic ones, and if you like role, free or risky addresses.

Your own wordingWrite the messages in your own words and language.

Phone numbers tooOptionally check phone fields as well: invalid and fake numbers are caught. Off unless you turn it on.

Never in the wayIf Domailfix cannot answer in time, the form still sends. Visitors are never stuck.

Questions

How much does the widget cost?

The widget is free to add. Each email it checks uses 1 credit, and a check that cannot be answered is free. Phone checks are off unless you turn them on, and also use 1 credit per number.

Will it ever block a real customer?

It only blocks the kinds of address you choose, and if Domailfix cannot answer in time, because of a slow connection or no credits, the form is never blocked: visitors can always submit.

Which websites does it work on?

Any website where you can add a line of code: WordPress, Shopify, Webflow, Wix, Squarespace and hand-built sites. It finds the email fields on its own, or you can tell it which fields to check.

Can someone copy my widget code to use my credits?

No. The widget only answers on the website addresses you list in your account.
