Email verification in scheduling apps prevents spam and no-shows. Cal Clear requires email verification on all bookings — free plan included.
What Email Verification Does
When someone books through Cal Clear, they enter their email address in the booking form. Before the booking is confirmed on your calendar, Cal Clear sends a verification email to that address. The invitee must click the verification link. Only after clicking is the booking confirmed. This simple step eliminates bot bookings (bots can't access email inboxes) and fake email addresses.
Impact on Booking Completion Rate
Email verification adds a small amount of friction to the booking process. Legitimate users who genuinely want to book with you will complete verification without issue. The people deterred by email verification are those making low-commitment bookings — exactly the people whose bookings you don't want.
Email Verification vs reCAPTCHA
reCAPTCHA v3 blocks automated bot submissions before the form is submitted. Email verification provides a second check after form submission — ensuring that even if a bot somehow passed reCAPTCHA, it can't complete the booking without email inbox access. The combination creates defense-in-depth against spam.
