Yes, about emails you are right. I'm pretty open to find another solution. We can also brainstorm a bit about the solution if you like :)
I think poetic.io has a much better UI, user experience (comparing it with SendSpace).
The real differences will be deployed in two/three weeks:
- previews on pictures (gallery), pdf and media
- background customisation for the transfer (for example with your brand)
The pro version will be completely different, I'll keep you updated on that ;)
with Dropbox you have to register, install a software and, most of the time pay,(actually you just have 2GB per account): https://www.dropbox.com/en/help/73
You have also to keep the file on your computer while is shared.
Here you have 3GB per transfer (unlimited number of transfers), no registration needed.
Do something different. Maybe a combination of keywords + geolocation for identifying files.
-- I've sent you a file at poetic.io!
-- What is the link?
-- Just go there, it's in your address.
