Questions & Answers

As answered by people managing ShipNote and Cert Decoder.

What's the story behind your product?

ShipNote's answer

I was shocked there wasn't an easier way to write thank you notes after my wedding, so I procrastinated and built and app to do it! Allows you to ingest data from any gift registry and send a thank you postcard to all of the recipients from the registry at once. Set up a template message to start with, then ShipNote will fill in the names and gifts from the registry and you can later edit the message for each individual. Possible to send dozens of thank you notes in minutes instead of hours. ShipNote prints and mails the cards for you!

Cert Decoder's answer:

I built certdecoder.com over the weekend for my own needs. Sometimes in my work, I need to verify and check certificate details.

Which are the primary technologies used for building your product?

Cert Decoder's answer:

certdecoder.com was built using just JavaScript and HTML—simple, fast, and with all processing happening locally in your browser, so no certificate data is sent to any server

How would you describe the primary audience of your product?

ShipNote's answer

Newlyweds and new parents staring down a stack of 20–100 thank-you notes after a wedding or baby shower — people who genuinely want to thank their guests but stall on the logistics: addresses scattered across registries, hand cramps, stamps, the post-office trip.

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

Why should a person choose your product over its competitors?

ShipNote's answer

Speed and price for real batches. A 100-card thank-you stack takes 10–15 hours by hand; with ShipNote it's about an hour, and every card is still individually personalized. $1.99 per card on orders of 10+ — printing, addressing, and postage all included — which beats both DIY (cards plus 82¢ stamps) and the other print-and-mail services. Address verification against USPS records before anything mails, so cards actually arrive.

Cert Decoder's answer:

Simple, fast, and reliable. Some similar tools can’t even decode basic certificates. I rigorously tested my tool with many real-world certificates and covered several edge cases where competitors fall short.

Who are some of the biggest customers of your product?

ShipNote's answer

  • Newlywed couples working through wedding thank-you batches
  • New parents after baby showers
  • Shower hosts and families sending batches on behalf of the couple

Cert Decoder's answer:

certdecoder.com is primarily built for developers, sysadmins, cybersecurity enthusiasts, and DevOps engineers.

What makes your product unique?

ShipNote's answer

ShipNote starts from your gift registry instead of a blank card. Paste your Amazon, Zola, Babylist, The Knot, Target, or Crate & Barrel purchase list and the AI turns it into a card-ready recipient list — names, gifts, and any addresses the registry shares. You write one message template, personalize a line per card, and we print, address, stamp, and mail every card the next business day. Nobody else closes the loop from "who gave what" to "card in the mailbox.

    Why? Because I built certdecoder.com and couldn’t find a decent place to submit it. So I said screw it — I’ll build my own. With blackjack and hookers. - Source: dev.to / over 1 year ago
