Fair question.
At least four reasons:
(1) I want to eventually transition from being a freelance copywriter... to working on PrayMore full time. That will require money. Because I have a wife. And a belly, that cries out for things occasionally. And asking for a monthly subscription fee seems like the best way to get that money from this work.
(2) If people pay for these emails, it will allow me to spread the word about this project faster. Because I will have money I can advertise with. Which would be great. Seeing as I would like for a lot of people to hear about PrayMore.
(3) You will be more likely to read these emails if you pay for them. Because they will cost you something. This isn't the main reason why I'm charging for the PrayMore emails... but it's true, and worth noting.
(4) I would love to one day be able to pay more people to help me with this project. Support staff. Online "community organizers," who can moderate Facebook groups and forums, etc. Spiritual directors and inner healing coaches, who can help people address the deeper spiritual blocks that "clog" their prayer. But paying people will require money. And so I am asking the people who sign up for these emails to pay a membership fee.
