I like that it can be used for multiple different marketing tactics including remarketing ads! It's also super easy too implement into existing platforms such as Marketo or Salesforce CRM systems which was helpful when we were trying out this software in our startup business, since those are some pretty big apps themselves (and not everyone knows how these programs work). Honestly nothing really came up against me negatively about xenomail so far - just keep using their free trial if you're looking at doing any research before purchasing something else because there isn't anything wrong per se but more than likely they'll provide customer support/help once purchased anyway. We decided from day 1 between us having 3 co-founders who all had unique roles within each other; one did UX design / UI development while another handled backend implementation details through building APIs etc.,.
