The three channels
In-app
- Adds a badge to the notification bell in the customer's StampClub
- Shows in their Deals list for 30 days after the campaign ends
- Does not buzz the phone — it is not a push notification
- Customers who turned off deal alerts can still redeem the offer
- A real email, sent from your business name
- Reaches at most 2,000 people per send
- Only goes to customers who have not opted out
- A bounce or spam report permanently stops future emails to that person
Digital wallet
- Updates the message on an Apple or Google wallet pass
- Trimmed to 180 characters
- Only appears when wallet passes are live on the platform
- Reaches only customers who added a pass
You can tick more than one. Each is counted separately against your monthly allowance.
In-app, in plain terms
This is the channel people most often misunderstand, so it is worth being direct: in-app delivery does not make anyone's phone buzz.
What it actually does:
- adds a badge to the notification bell inside StampClub
- lists the offer in the customer's Deals
- keeps the offer redeemable at your counter
A customer sees it the next time they open StampClub, which for most people is the next time they are in your shop. That makes it well suited to offers that reward someone already walking through your door, and poorly suited to anything time-critical.
Customers who turned off deal alerts do not get the bell badge, but they can still redeem the offer if you mention it in person.
Email is the only channel that reaches someone who is not thinking about you.
Things to know before you rely on it:
- it reaches at most 2,000 people per send
- it only goes to customers who have not opted out
- the subject line is your campaign title and the body is your 300-character message
- it is sent once, and never retried
A bounce or a spam complaint permanently stops future emails to that person from your business. That is a deliberate protection for your sending reputation, and it cannot be reversed from the dashboard.
Digital wallet
If a customer added your card to Apple or Google Wallet, this updates the message on their pass. It is trimmed to 180 characters.
The toggle only appears when wallet passes are live on the platform. It is not something you enable per business.
Choosing between them
- Something happening today: email, since in-app waits until they next open the app
- A standing offer for people already visiting: in-app is enough, and does not use your email allowance
- A reminder for your most engaged customers: wallet, since only regulars bother adding a pass
For most independent shops, in-app for everyday offers and email for the few that genuinely matter is the right balance.
