Double Opt-In | Overview - Zoho Forms

Double Opt-In


When you share a form publicly, there is a possibility that you will receive malicious or unsolicited form entries in bulk from spammers or spam bots. To control spam entries, you can include an Email field in your form and use the Double Opt-In option in Zoho Forms. This option triggers an email to the respondents that requires them to confirm their entry to complete the form submission process.

  How Double Opt-In works

  1. Respondent submits a form.
  2. Respondent is redirected to a Thank You page.

  3. Respondent receives an Opt-In email (with a link to Opt-In confirmation page).

  4. Respondent is redirected to Opt-In confirmation page.

  5. Respondent can Opt-In or Opt-Out.
  1. Once a customer clicks Opt-Out from an email address, no record can be submitted with that email address. An error message will be thrown when attempting to submit a form with opted-out email address. 
  2. If a respondent accidentally opts out but still wants to submit a form with the opted-out email address, then the record associated with that email address has to be deleted from Opted-Out Entries. This allows them to submit a form again. 

Configuring Double Opt-In

To configure Double Opt-In for your form,
  1. Navigate to the Settings tab > Spam Control.

  2. Click Double Opt-In and click Configure Now.

    You can also display a Splash Message for a few seconds while the respondents are redirected after form entry.

    Rich Text:
    If you wish to display a Thank You message to acknowledge your respondents and provide them with the information to proceed further after they submit an entry, select the Rich Text option. 
    You can change the font style of the text message from the Font Family dropdown.
    Note: If you wish to choose any web font other than the Default Fonts available, click Manage FontsLearn more about changing the font style.
    Redirect To Website: 
    If you want to take your respondents to a website to provide more information about your product or service after they submit an entry, select the Redirect to Website option. Enter the URL of the website and choose if you want the URL to open in the Same Window, a New Window, or the Parent Window.

    Opt-In email

    When you choose to configure Double Opt-In for your form, a link to the Opt-In confirmation page will be sent to the respondents via an Opt-In email after they submit an entry.

    To configure the Opt-In email template,

You can use the From address of your org users or any Zoho Group that you are the admin/ moderator of by clicking the Add Sender Email option in the dropdown. You can also add a From Name to this email.

    2. In the To address, select the required email field added in your form. An email will be triggered to the email address entered by the respondent in this email field.

    3. You can change the default Subject and Message as per your preference and merge values from form responses by clicking the   icon and selecting the required form fields. You can change the font style of the Message's text from the Font Family dropdown.
