I like that you can send emails with different layouts for each recipient (such as text only or photo). The layout options are limited compared to other services such as Mailchimp - but it works well enough! There is nothing really wrong about this service; however there could be more features added so people don't have their email filled up by promotional material from multiple companies at once- which makes sense since most of us do not want 100s upon hundreds sent out every day via our accounts!! However if one does receive too many messages/emails per hour then its best just unsubscribe instead because otherwise we will get spam complaints due to all these unwanted promotions being received daily through social media etc.- even though some would consider them useful advertising.
