Okay, it would be very powerful feature one day if it could import from google spreadsheets and export there as well. That means full marketing automation would be available using Zapier and I think the automation of things is where the marketing game is heading right now and will be basic in coming years. Google spreadsheets because it is already online, it can remove and add rows automatically without downloading or uploading any files.
This would mean this can be done:

Automated targeted ads.
For example somebody clicks a link on your email marketing campaigns, link is about I don't know, shoes. Subscriber will be moved to a list of "people who are interested in shoes" and google sheet will be updated with their information. Zapier picks up that information, sends the info to facebook leads and bang, they will see ads about shoes in their facebook feeds.
Or another example:
Somebody buys contact lenses in your e-commerce shop, Woocommerce picks that up, pushes customer data to google spreadsheet using Zapier, Mailwizz picks up the subscriber from same spreadsheet file, imports it to the list, autoresponder is set to send him a contact lense offer in 3 months when his current contact lenses are going to expire.
I wish I was better with that stuff, I just discovered it's potential, but the value you can create with that stuff is massive if you are creative!
Thanks!
