The success of our project was due to my previous experiences with several other companies that were also in this business, but most failed miserably at providing any real value or results for us as customers (except maybe cost savings). My experience is primarily from working directly inside one such organization where we built up everything ourselves using off -the shelf solutions like MailChimp etc., so I'm used only seeing what works/doesn't work through customer feedback after deployment without much hands / eye view into how things could have been done better had they known about it beforehand! So far no issues encountered while managing over 200+ campaigns across various segments & countries within 2 years since launch date.
