Modify email signup in footer on archtype impulse theme

Topic summary

A user wants to implement a two-step email verification process for their footer signup form on the Impulse theme, similar to what Copper Cow Coffee uses on the Motion theme. They’re concerned about spam signups and want to verify subscribers before adding them to their Klaviyo list.

Current Limitation:

  • Impulse theme lacks built-in double opt-in functionality out of the box
  • Default Shopify forms don’t include verification steps

Recommended Solution:

  1. Integrate Klaviyo with Shopify via the app store
  2. Enable double opt-in settings within Klaviyo for the email list
  3. Replace the default theme signup form with a custom Klaviyo form
  4. Use Klaviyo’s form builder to create and embed a customized signup form in the footer

Outcome:
This approach requires theme code customization to remove the default form and add the Klaviyo form. Once implemented, subscribers will receive a confirmation email requiring verification before being added to the list, effectively preventing spam signups.

hi, the company copper cow coffee uses the archetype theme Motion and i believe have customized the email footer signup to not be typical with the theme - it appears that signing up offers a two step verification in checking a signup email, and my Impulse theme does not have this functionality. I just want to confirm there is no way to customize my email footer signup out of the box to have it two step verify before submitting to my Klaviyo list, and i will need to have that customized? It makes more sense to me to have it go to Klaviyo vs my shopify customers, as there is no double check that it is spam (and indeed, anyone can signup and i have had a rash of signups through this form.)

You’re correct that most Shopify themes, including Impulse, do not have built-in functionality for double opt-in verification for email signups directly out of the box. To achieve this, integrating with a service like Klaviyo, which supports double opt-in, is a great solution. Here’s a simple way to approach this:

  1. Integrate Klaviyo with Shopify: Ensure that your Shopify store is integrated with Klaviyo. This can be done through the Klaviyo app in the Shopify App Store.

  2. Set Up Double Opt-In in Klaviyo: In Klaviyo, you can enable double opt-in for your email lists. This means when someone signs up through your form, they will receive an email asking them to confirm their subscription.

  3. Customize Your Signup Form: Use Klaviyo’s form builder to create a signup form that you can embed in your Shopify store. This form can be designed to fit your theme and can be placed in your footer or any other section of your site.

  4. Replace Shopify’s Default Signup Form: Replace the default signup form in your Impulse theme with the Klaviyo form. This involves editing your theme’s code to remove the default form and add the Klaviyo form.
