It seems like no one seriously considers Email anymore and a lot of times spam scripts on servers may send what you do correspond to junk thus making it difficult to stay in touch. Members have a lot of options and though they will visit they may 'forget' to. When they do get a notification of sorts: newsletter or reply notification they come back - if it doesn't go to Junk first. Many have also gone to the social giants and these giants have tapped into people's phones by being able to send them notifications in apps and and interfaces beyond Email. So my question for discussion: what are some creative ways you use to stay in touch with your site's members beyond the newsletter and their visits.
