To prevent a huge amount of spam email via the contact form (or similar app), we strongly recommended to install a Captcha service to block bots.We allow to implement own Captcha solutions or services in the form.
We also provide a API to connect with the reCAPTCHA service to secure your form.

What is reCAPTCHA?
reCAPTCHA is a free service that protects your website from spam and abuse. reCAPTCHA uses an advanced risk analysis engine and adaptive challenges to keep automated software from engaging in abusive activities on your site.It does this while letting your valid users pass through with ease. Powered by machine learning. Hundreds of millions of CAPTCHAs are solved by people every day. reCAPTCHA makes positive use of this human effort by channeling the time spent solving CAPTCHAs into digitizing text, annotating images, building machine learning datasets. This in turn helps preserve books, improve maps, and solve hard AI problems.
