Can I allow leads to opt out of emails from Zoho CRM?

The best way to allow leads to opt out of emails from Zoho CRM is by using Unsubscribe Forms.
Follow these steps to create Unsubscribe Forms:
  1. Go to Setup > Developer Space > Webforms > Unsubscribe Form.
  2. In the Unsubscribe Form page, do the following:
  • Enter your website address in the Return URL field.  
  • Click Generate HTML code.
  • Copy and paste the generated HTML code into the HTML editor and save it as an HTML file.
  • Click Finish.
Your leads can click on the unsubscribe option available in your email template, enter their email address and proceed. This will immediately enable the email opt-out field and you'll no longer be able to send emails to that record.
