Email Field


An Email Field is a single-line field that only accepts a valid email address (it checks for an "@" and a domain).


Plan: Email is available on the Advanced plan and above. On the Free plan you can still try it on one live product with a Premium option set. See Plans and feature availability.



If a customer types something that isn't a valid email, OPTIS shows a message under the field:



When to use an Email Field


  • Account or newsletter signup - collect an email to send updates or promotions.
  • Event registration - send tickets, reminders, or access links.
  • Contact for a custom order - so you can follow up about a personalized item.


How to add an Email Field option

Step 1: Add the option


Open 1. Add options, click Add option, tick Email under Text input on the New options tab, then click Add options.




Step 2: Name it


Enter the Label on product (e.g., "Enter your email address:"). Use Label on cart if the cart and order should show a different name. Tick any options below based on your needs:


  • Required field if customers must fill it in
  • Hide option label to hide the label



Step 3: Save and test


Click Save, then open the product page on your store to check that the Email Field works correctly.



Option settings


Set only what you need - all of the settings below are optional.




Default value and placeholder


  • Placeholder text - a faded hint shown inside the field. It disappears once the customer starts typing. Available on every plan.



How the placeholder looks on your storefront:



  • Default value - an email that is already filled in when the customer opens the product page. Available on the Advanced plan and above.



How it looks on your storefront:



Help text


Add a short note explaining what to enter. Choose how it's shown: Tooltip, Below the option title, Beside the option title, or Below the option.



Limit the number of characters


Set Min character and Max character to control how much customers can type. Available on the Advanced plan and above.



  • Min character - if the customer's email is shorter than this, OPTIS shows a message under the field, e.g. Min character: 5.



  • Max character - once the customer reaches this limit, OPTIS stops accepting more input and shows a message under the field, e.g. Max character: 20.



  • Character counter (optional) - turn on Character count for text box in Settings > General Settings > Option type setting > Text input to also show a running count (e.g. 12/50 characters) under the field. See Limit Characters for Text Input.



  • Not a valid email? Regardless of length, OPTIS shows Email format is invalid. You can change this text in Settings > Translation Texts > Default text customization > Product page.



Charge an extra fee (price add-on)


Charge more when a customer fills in this field. Available on the Advanced plan and above; Upsell product needs Platinum.




How the price add-on looks on the storefront:





Show or hide with Visibility (conditional logic)


Show or hide the Email Field based on another option - for example, only show it when the customer answers "Yes" to "Would you like to receive exclusive emails with discounts and product updates?". Available on the Advanced plan and above. See How to set up Conditional logics?.



Option width


In the Display tab, set Option width (25%, 33%, 50%, 67%, 75% or 100%) to control how much horizontal space the Email field takes.
