NIP-17 DMs? Does your client support them?
Can you add a npub option for receiving notifications? nostr:npub1zk6u7mxlflguqteghn8q7xtu47hyerruv6379c36l8lxzzr4x90q0gl6ef nostr:npub1xv8mzscll8vvy5rsdw7dcqtd2j268a6yupr6gzqh86f2ulhy9kkqmclk3x 🙏

Nothing complicated, just a DM (giftwrappex or not) with the link instead of an email.
Would you provide an nprofile so we know what relays to publish the dm to?
I don't think users know to find their nprofile. Ive been here for years and dont know of a quicker way than going to nostr.band or something. Should clients display an iPhone to copy nprofile 🤔
This is why DM integration is harder than expected. But thanks for the feedback, maybe we can find a way to easily add it if we see more usage of ZapPlanner
