I like that it's been customized for my business (I sell custom t-shirts) - there are various templates available as well which you're able to customize further with your design options! The best part about RapidMail was getting started using their team in order to get set up quickly without needing an expensive service provider or having technical knowledge. There isn't much to dislike when working from home - but if there were things they could improve upon would be more ease/time saving features regarding tracking contacts etc., better ability to share links through emails directly rather than have them open separately. We've used other services before such as MailChimp; however we found this one most appealing because we had more control over our branding & colors vs others where ours got lost amongst all else.
