What it does

Block invalid, disposable and typo'd emails.
Flag risky VoIP numbers and fake details.
Verify in real time as the form submits.

Why it matters

Guarding the form keeps fake and bot signups out of your CRM at the source — cheaper and cleaner than removing them later, and it keeps every downstream metric honest.

The cleanest database is one that never lets bad data in. Verifying at the form — in real time — blocks invalid, disposable and bot signups before they become records, which is far cheaper than cleaning them up later.

Questions

Frequently asked

How does it block fakes at the form?

Your form calls the API on submit; it returns a status in milliseconds so you can reject invalid, disposable and obviously fake entries inline.

Will it slow down signups?

No — checks return fast enough to validate as the user submits, with a graceful fallback.

Does it cover phone too?

Yes — it can flag risky VoIP numbers and malformed phones at the same time.
