To add a registration form to a Klaviyo email, you should create a new list for each of the three products you will be launching in the "Lists & Segments" tab. Then, in the "Forms" tab, click "Create Form" and choose the "Signup Form" option. Select the list that corresponds to the product for which you are creating the form, customize the form fields as desired, and save the form. Next, navigate to the "Campaigns" tab, create a new email campaign, and design your email content. Click the "Form" icon in the email editor toolbar, select the form you created earlier, and customize the button text. Preview your email to ensure that the form appears correctly and then send the email campaign to your existing customers.

OR

You can create a separate landing page for each product and add a registration form for each product on the respective landing pages. You can then link to each landing page in your email, allowing customers to sign up for the pre-sale subscription list for the product(s) they are interested in.

Alternatively, you can create a single registration form with checkboxes for each product, allowing customers to select which product(s) they are interested in. You can then use Klaviyo's segmentation functionality to separate customers into lists based on their product selections.

Thanks for your helpfull reply! 

I have created a landing page with an email form. This is linked to the new list and I linked the list to a welcome flow. When someone registers, I see on the list that nobody registered but I do see a subscriber on the sign-up flow. And a welcome email is not automatically sent out. Do you know how this is possible?!

Check if the list is set to "Double Opt-in." If so, subscribers will receive a confirmation email asking them to confirm their subscription before being added to the list. If the list is not set to Double Opt-in, check if the subscribers are being added to the list manually by going to the list and checking the "Add a Subscriber" button.
