Hi, When user subscribes by giving email ID, I would like to verify the email id. Could you please guide me how I can add this feature. Thanks.

  1. Navigate to the “Settings” section and select “Notifications.”
  2. Locate the “Customer account welcome” email notification and click on it to edit the content.
  3. In the email template, you can include a verification link or a verification code that users need to click or enter to confirm their email addresses.
  4. Modify the email content to explain the verification process to your customers clearly. You can provide instructions and a call-to-action button or link for them to complete the verification.

Thanks much appreciated, is there a way to request mobile number along with email when user subscribes? Impulse theme already have Signup form and I would like to configure it to take mobile number aswell. I can see there is an option to enable SMS subscription in checkout. Can I embed it in subscribtion page (the page with sign in form) or in sign in form somehow? thanks.
