Hobbyists' lists aside, if your mailings are not making your enought to pay 0.25c-1c a pop then you are in the wrong business.
I would much rather be one of the 5 e-mail messages in the prospect's inbox and pay something for it than be one out of 100 and pay nothing.
For Hobbyists' and non-profit lists, it shouldn't be too hard explaining the situation to people and asking them to add you to their address book right away.
You over estimate the average user.
for those who treat (on-line) business as a business.
An over generalization that assumes all online businesses have a similar business model.
Besides, maybe now people will start cleansing their lists and remove addresses that don't produce clicks or other activity over a period of time as they should have been doing all along, instead of sending stuff to the black hole and hoping that one day that unresponsive subscriber buys.
Another generalization that everyone who uses email in business is spamming, is an affiliate, etc. I use a closed loop, double opt-in set up. I have thousands who may not respond for months who still want these emails. I only hear from them when they dont get my emails due to a glitch or whatever.
I wont pay Yahoo or AOL. I will simply let their users know that this extortion adds to my bottom line, thereby increasing the costs for my users, so if they still want my services (100% of my email database that is 30k+ request to receive my emails), they will need to provide an alternative email.
IMO others will do the same. That leaves mainly the bulk emailers to pay the ransom, so the actual % of spam in the inbox for the Yahoo or AOL user will be higher. Freakin' brilliant move by these two clueless giants.
