Provide email sending functionaility and sequences to end-users - any open source options?

Hey all,

We’d like to find a way that we could introduce email building and sending functionality to our end users - so they could send marketing emails / sequences and drip campaigns - say similar to the likes of Lemlist.com - has anyone achieved this within Wappler without any third party code/open source - or if that’s not possible, if anyone has achieved this could you please point me towards any resources/open source code we could take a look at to start thinking about how we could achieve this.

Many, many thanks in advance for this one.

Matt
