Hi Nick,
We don’t have any specific recommendations but certainly if you choose to use WooCommerce along with our WooCommerce Tickets plugin you can potentially benefit from the raft of extensions that exist for that ecommerce solution 🙂
That said, I’m pretty sure most of the ecommerce engines supported by our ticketing plugins will have similar capabilities (whether built in or made available by adding a further plugin) and so the best thing to do is settle on the ecommerce engine that best fits your needs, whether that is WP E-Commerce, WooCommerce or something else and see what’s available in terms of marketing addons.
Does that help?
