I love that it is easy to send out emails with zero agency! It's so simple you can just let your email program do all of the work for sending an email blast without any extra time being spent figuring things like frequency or recipients lists - this saves me tons of hours every month as i don't have to spend my valuable working hours doing those tasks myself!! Nothing at moment but if there was one thing they could improve upon would be support when using their API services which are very limited compared to other tools we've used before (namely Mailchimp). Sending our sales communications monthly has been super efficient thanks to ZAgency. Our customers get notified about new products almost immediately after release date plus receive regular updates from us throughout each quarter via daily newsletters sent straight into their inboxes. The tool lets them choose how many times per week notifications will go live by simply adjusting settings within.
