I agree with Jim (almost). Prints are a recurring, low involvement business in one way – you should be able to setup a web shop and forget it. There will be overhead dealing with people’s emails, returns, etc. But I’d say it’s worth doing it.

Sell code is something I’d stay away from, for the time you have is not enough to cater to customers’ varied asks.

Market Unmark – Yes please! Go for it! Marketing it is the least of what you should do. Even if it’s word-of-the-mouth, lowfi virality, go for it! I’m interested in seeing too, how many people pick up Unmark Premium. I have installed Unmark for myself, but my interest is less in bookmarking and more in read-later, so it wasn’t a tool suited to my needs. But I’m sure you’ll find a good market in the Creatives/ToDo space.

If nothing else, send a one-time email to your paying customers asking them why they use it and what they like about Unmark. A survey would take you miles ahead in understanding how to market it.

Oh, and market it without changing much to it at first. See what customers do with it. Invite paying members to a private Discourse or slack forum. See what they like to complain about and chirp happily about. Only then think about tweaks.

About offering 1-1 help – maybe consider building an online course for darkroom printing? Else do go for 1-1 coaching for people who need it. Use your micro.blog contacts to find people who would need your help.

So, I guess I’m saying – do most of the above.
