So a fun bit of math: within Canada, the postage fee on an oversized envelope is $1.80. With 2048 applicants to notify (IIRC) SSHRC is spending over $3600 on postage alone for the notifications. Now the actual total is obvious far higher when you consider that many applicants are located internationally (postage to Georgia, USA is $3.00 and to the UK is $6.00), the letters of those who received fellowships will be thicker and possibly overweight (more $$$), they needed to by the envelopes and paper (and print in COLOUR!), and pay for the labour to stuff and mail all of these.
A bit of back of the envelope math and I get somewhere in the neighbourhood of $4500+labour, all of which could be avoided through the magic of email. It's not enough to fund another fellowship or anything, but as someone on the waitlist I'd be happy to take the money off their hands...
