Engineer from Cratejoy here!

My assumption here is that you're not asking about a 'preorder' type of feature, but rather you're asking for a "My store is closed, sign up for my email list instead!" feature.

For storing email information I'd recommend just going with mailchimp, and then choosing one of the following options.

There's a couple of relatively easy options for you here:

1) Create an alternate version of your subscribe.html page and literally render it with an if statement

Something like this: --At the top of the page {% set is_open = True %}

{% if is_open %} -- ENTIRE CONTENTS OF YOUR EXISTING SUBSCRIBE PAGE HERE!!! {% else %} -- DESIGN A NEW PAGE WITH JUST AN EMAIL SIGNUP HERE!!! {% endif %}

Doing this will enable you to just flip that is_open to False in order to toggle your subscribe page, and without your subscribe page listing your products (default functionality) you shouldn't have to worry about anyone 'accidentally' ordering any of your products.

Downside: requires a little bit of dev time

2) Go with some sort of popup on your index.html page and remove your subscribe links when you're full

Do some research with fancybox, lightbox, or some other equivalent javascript, design a simple 'give me your email!' form, write 3 lines of javascript, and you should be good to go

Downside: requires a little bit of dev time and your /subscribe link is still there and people can technically still wind up there if you've forgotten to remove all of your links, or if they get a link to /subscribe from a google search or if you've ever distributed advertising which points there.

The code for how to do an email signup for mailchimp should be pretty trivial and you'll just have to style it to look appropriate in your site. Head over to mailchimp for more information on that.

If you have any questions on this just email [email protected]
