Protect your Insightly form from bots

In short: To stop spam on an Insightly Web to Lead form, turn on Web to Lead in System Settings, copy the form HTML Insightly creates, run it through the SpamKill Setup Wizard and paste the protected code on your page. SpamKill checks every submission without a CAPTCHA and real leads still arrive in Insightly, tagged as web leads. It takes about 10 minutes.

Bots are filling your Insightly web form with fake leads. Protect your Web to Lead form with SpamKill and real enquiries keep arriving in Insightly as leads, with your lead source and owner. One limitation to know first: Insightly lets you build Web to Lead forms only on its paid plans and trial.
