UXi® Commerce doesn't have a built-in "Newsletters" module and we aren't going to add it in the near future.
We use an approach completely different from average shopping carts. Instead of trying to put all possible site features into one product, we made a product that would be absolutely the best at just one thing: it’s the best shopping cart software available.
And as UXi® Commerce can be added to any web site, you can use it with any CMS system you like, use whatever newsletter management software or service you think is the best, and so on. It gives you the flexibility to use it as one great component among many.
So if you want to send e-mail newsletters to your customers, you can use any 3d-party newsletter service.
We recommend that you to use MailChimp to send newsletters. They are very good at it.
- Sign up with MailChimp. They have a free plan, so you don't need to pay anything.
- Prepare your list of subscribers. Export your subscribers' emails to a CSV file.
- Create a new list in MailChimp and import your CSV file there. The detailed instruction with video tutorial is available at MailChimp's site.
