WHAT IT IS Upload a photo (or pick from Unsplash), write a message, optionally add a 60 second voice note, and send a 4×6 postcard. QR code printed on the postcard links to a “digital card” that plays the audio. $5 flat, printing + postage included. No account required.
WHY I BUILT IT I love mailing postcards to my family but hate it's a hassle (finding card, buying stamp, handwriting, praying it arrives on time). I wanted to merge the charm of physical mail, the warmth of voice messages, and the efficiency of software.
HOW IT WORKS Built with Next.js, Supabase, Stripe, Resend, and Lob. QR codes link to hosted audio. Stripe handles payment. Lob prints and mails the cards. Resend emails status updates.
WHAT'S DIFFERENT - Voice note + physical card combo - Minimal editor, no sign-up friction - Transparent $5 price (everything included)
TRY IT FREE 1. Go to https://sendkeeps.com 2. Create your card 3. Use promo code SENDKEEPSFREE for a free send (first 50 people)
FEEDBACK WANTED - Editor UX - QR/digital card flow - Address autocomplete UX - Critical missing features - Interesting use cases (wedding thank yous, airbnb hosts, etc)

Some honest feedback: isn't the magic of a postcard, especially a physical one, linked more to the handwritten aspect of the note, and less the voice? My old firm emphasized hand written thank you's for everything because it showed time and effort into this sort of item but I feel like that get's lost with a digital postcard + audio file link. Especially when considering going back and reading notes versus having to scan a link.
Curious how you're thinking about all this.

It was also just a fun way to learn how to connect all these technologies and be able to trigger an event in the real-world from a few lines of code.
Appreciate the feedback.

Your approach is great; I can see a good need for this, and it is a unique offering which amends rather than replaces postcards in my view.
I could even see you having real post cards that have a QR code to the voice version that you sell in shops.
