I've been saying this for a while. Best decision we made was signing up for capitanU.
$20/month and you upload as many videos as you like. Also send all emails to coaches from that site. Simply use the pull down and choose the school and the coaches names pop up. Check the coach and have DD send email.
If/when a coach opens email you get a notification that a coach read your email. If a coach watches a video you get a notification of who watched what.
This helped us know which camps to attend and which camps to skip (if they didn't open emails we didn't go to their camps). Probably had 3 or 4 schools who's camps DD would have attended if she thought they were interested but not opening emails indicated that they weren't. 4 camps at $150 each ($600) paid for the site for 3 years. Only used it for 2 years. Probably the best money every spent imo.
When DD sent her travel game schedule for a weekend we knew what schools were coming to see her simply by who opened her emails.
Very valuable information.
Every coach we have heard speak on the subject has said he/she automatically deletes emails if they can tell they are though one of those services. Obviously we have not heard from every coach there is, but the message is consistent from the ones we have heard from.
