Email segmentation and automations + sales funnel

It would be great if we could segment our audience and send email campaigns to specific groups, or build email automations and workflows. I know we can integrate zaap with mailchimp and other platforms but it would be great if I could just go to my audience slected the people that came trhough a specific lead magnet and send (only them) them a brodcast for example. It also be great to be able to do sales funnels with our zaap products such as upsell and down sale. Here is an example: If I sell a digital product it would be awsome if I could ask the person on the check out if they also what to buy this other complementary product. Or after purchasing a product, directly link them to another page and ask if they would like to upgrade and book a paid meeting for example. I love zaap and its always my 1st choice but these little details limit my options and I end having to work around it with elaborate schemes on other tools, or just choose another tool alltogether that offers these options, which is a shame.
