I work hard to have few emails in my inbox. Now I can tag them so to speak with this program, archive that same email away & then not worry if someone doesn't reply because I'll be reminded. Thank you for creating such a needed program. Should be in every email program -- 5-stars by glanfam - Version 1.1 - Sep 20, 2012 What it does, it does simply and well. Reminders link back to the original email. No need to rewrite them into your calender or a reminder program. Best of all, it takes seconds to use, Can't believe it…. -- 5-stars by Fremont47 - Version 1.1 - Apr 11, 2012 More Reviews: AppStorm - "It’s helped me to become more prompt with re-requesting information when needed, ensuring that I stay up to date with work. RSVP is simple, user-friendly and fixes a need that should have been fixed by email providers a long time ago (in my opinion)" Addictive Tips - "RSVP more than justifies the $1.99 you will spend on it"
