Can Swipify be an alternative to email marketing apps like Klavio, Omnisend, Seguno, SmartrMail, Automizely, Privy and others?

Yes! Not only that Swipify collect emails for you, but it is also generating personal emails to your customers, based on the data they shared on Swipify app (Swiped for every product if they liked it or not) - and it is all done automatically, so you don't need to do anything and also the mails are personal and different for any customer.

For instance, customers get price drop alerts if an item they liked is on discount, and they get mails if there is a new item that is like other items he/she likes, etc.

So, yes email marketing is a huge channel, nd Klavio, Omnisend, Seguno, SmartrMail, Automizely, Privy, and others are doing a good job, but it is also a lot of work, and Swipify is doing all the work for you, and it's doing it better than you'll ever be able to do it.
