You're living the dream :) I've got my own product launch coming soon, and I hope things go even half as well for me as they have gone for you.
I'm interested to hear about your marketing efforts. You mentioned that you have 16000 mailing list subscribers and that this has been effective in terms of growing sales. How did you find these subscribers?
Are there any other marketing hints you might be able to give to a soon to be launching app?
Cheers, Eli
Most of 16000 emails on the list are trial version signups. To activate the trial user needs to enter the email address and a simple activation code that we send to that address.
A lot of times trial users like your app but will forget to buy it because they don't need it immediately. About once or two times per month we send out news about product updates and occassional special offers ($10 off for Christmas, for example). That brings a lot of users back to the product.
Another thing that drowe early sales was giving lifetime free updates to early adpoters. So people bought PG even though they didn't need it yet or important features were missing. We did this for the first three months.
Wish you lots of success with your launch!
