The Web3 Email Notification Service we released in Nov 2022, now supports SMS & Push notifications
First, a quick recap about why you should care…
Problem: dApps today are set up to fail
Right now, dApps on every blockchain suffer user retention and engagement problems.
Why?
Web3 notifications suck.
As a result, dApps don’t have a good decentralised way to continually engage users; to notify them of events that require their attention, or encourage habit-forming behaviours.
Right now, notifications suck for users and developers
Without notifications, users must remember to constantly log back into your dApp to see if anything has changed, while following a Twitter and/or Discord for alerts. This is an extremely poor user experience that is limiting dApps from succeeding.
If Web3 developers want to use email, SMS or push notification services in our dApps, we’re forced to build centralised off-chain services to manage this for us. This both adds development overhead and also introduces points of failure.
So, as developers, how do we send notifications in the most decentralised way possible, without having to set up lots of new infrastructure?
Creating a Web3 Notification Service (W3NS) - email notifications
I’m part of a team that’s solving the Web3 user retention and engagement problem.
We are creating a decentralised, secure notification service for developers building dApps on any chain, starting with IC.
In late 2022, we released our first product on the IC - an email notification service built with HTTPS outcalls. With this service, developers could engage users with transactional emails straight from their IC canisters.
We used Courier’s idempotent API to make HTTPS calls. Courier then allows developer to configure their email provider of choice (e.g SendGrid, Gmail or SES) to send user emails.
Update: Finally, SMS and Push Notifications for IC dApps!
We are excited to announce that we’ve expanded our Web3 Notification Service (W3NS) to support SMS and Push notifications (both Web and Mobile).
You can now send immediate notifications via Email, SMS and Push to individuals and segmented groups.
W3NS is idempotent and scales cheaply. It also supports dynamic API keys, so users can Bring Your Own Key (BYOK) to send via custom domain emails and vanity phone numbers (branded).
You will be able to subscribe users to specific Topics, which can then be used to broadcast to many users of similar interests, i.e. someone interested in the results of games in a fantasy sports league.
Here’s the highlights of this release:
Dynamic API keys (Bring Your Own Key - BYOK)
- Support the setting and deleting of keys indexed by the canister that calls them.
- Stored in a private data structure on the canister, so only needs to be set once and then you can call the send functions as needed.
SMS notifications via Courier
- Expand support and the canister interface to include a function that allows consumers to also trigger an outcall that SMSes on their account’s API key.
Push notifications via Courier (both Web and Mobile)
- Expand support and the canister interface to also trigger an outcall that sends Push on their account API key (They will have configured FCM in Courier already)
- Requires the collection of the user’s device ID (whether web or mobile to support Push notifications) by the consumer to send
Targeted individual user notifications
- Support specific users for their email, phone and push channels, interface needs to be able to select a channel and the user to target (identified by their email, phone number or device ID depending on the channel)
Subscribe users to Topics for broadcast notifications and sending broadcast notifications to Topics
- Create Topics for Push notifications via outcall.
- Support calls to the canister to Subscribe users to specific Topics for Push notifications
- Support calls to the canister to unsubscribe users to specific topics for Push notifications
- Support the sending of a notification to a Topic via outcall
Documentation for how to set up permissions requests for consumers of Canister for Push notifications
- Documentation for how to send SMS, email and Push as a consumer

What’s next?
Our short term goal is to build an Open Internet Service that’s easily accessible by builders on any chain and provides:
- Improved frontend UI
- Notification scheduling & flow designer
- Automations based on events and user behaviours
- Cross-chain email, SMS and push notifications
Our end vision is a full-stack Web3 marketing and user-engagement platform.
