I manually sent 13 welcome emails this morning...what's your welcome email?

Hey everyone!

One part of the bootstrap start up life that I love is watching people sign up! It feels great at first but then the battle to keep them there (before asking for $$$) sets in.

So, I started to send emails personally. So personal I leave my phone number there at times (tbd if this is a good idea). I like to say "Welcome [Insert Name] to Twigflo - Not a bot!!". So far I've been having some luck and generating some good user feedback from this.

So, what's unique or interesting about your welcome email?
