How many times have you thought: “Shoot, I’m about to run out of my shave gel,” or “Well, I don’t really need another pair of Crocs,” or “A golf trip to Florida would be nice,” only to get a 6% cash back notification about that very thing a day later?
At that point, it feels impossible not to buy it.
That’s the power of push notifications. They’re hard to miss — they have a ~70% higher open rate than email — and pop up at just the right time, serving as the perfect nudge to push people toward conversion.
But they also come with a risk. It only takes a few too many notifications to go from “This is just what I’ve been waiting for!” and “Ugh, get this off my screen.”
Below we share how to toe that line, which notifications to start with, and how to make sure they’re working.
How to Do Push Notifications Right
1. Stick to One Offer Per Push
Don’t try to cram multiple offers in one push, hoping that one stands out to a cardholder. They’ll probably miss the one you want them to see, or worse, makes them feel like you don’t know them at all.
Pick offers you think would be most relevant for new cardholders, folks who’ve already redeemed cash back before, or high-frequency spenders in a specific category (like gas or grocery).
Or pick offers that are time sensitive, like:
- “Flash” offers, where a user can only redeem it during a certain period of time.
- “While supplies last” offers: A user can only redeem an offer while it’s still available. Once a set number of users have redeemed an offer, it closes.
Multiple offer promos can always go in an email roundup instead.
2. Keep Copy Under 50 Characters
Anything longer gets truncated on most lock screens anyway. Treat the character limit as a creative constraint: how much value and urgency can you fit into a single line?
Examples of push notifications that work:
- “10% back at Proactiv, today only”
- “New offer: $5 back at Cicis Pizza”
- “Last day for 12% cash back at Lids”
3. Link to the Offer
When someone taps on a push notification, they expect to go straight to the offer. If you’re not sending them there, they might just close the app.
Take them to the exact offer you’re advertising — the one they tapped to see.
4. Send Early Morning or Late Evening
Cardholders tend to check their bank apps first thing in the morning or last thing at night. Between 7 and 9am or between 7 and 10pm are your strongest windows for push notifications.
Middle of the workday is usually wasted real estate — unless you know, for example, that most of your cardholder base is younger students who could go for some cash back at a QSR restaurant.
Run A/B tests to find your timing sweet spot.
5. Earn the Interruption
Before you configure any notification, ask yourself if you would act on the notification.
Is it clear? Is it compelling? Would it stand out among the other notifications already sitting on their lock screen?
Every forgettable or irrelevant notification you send degrades a little trust. And over time, it trains cardholders to dismiss your notifications without reading them.
3 Push Notifications Worth Sending
1. A Welcome Push
Right after someone signs up or after you launch a new rewards program is a great time to inform them about the offers available to them.
Keep these short, celebratory, and link directly to the offers section. For example: “Your cash back offers are live 🎉 Tap to start earning.”
After this, every push should be tied to a specific category, SKU, or moment.
2. A Time-Sensitive Offer Alert
Scarcity closes the gap between passive interest and an actual purchase. Push notifications with a specific offer that ends soon at a brand the cardholder recognizes gives users a reason to act right now.
For example:
- “10% back at The Container Store ends tomorrow”
- “$7 back at Logitech for back to school week”
- “Last chance: 8% back at Manscaped”
Send these sparingly — once a week is usually plenty. Try to time it with a seasonal moment if you can, so (1) it makes sense why you’re promoting it now, and (2) is extremely relevant to cardholders.
3. A Redemption Notification
The single highest-engagement moment in your rewards program is when cardholders earns cash back. Make it a celebratory occasion:
- “You just earned $3 back 🤑”
- “Cha-ching! Your Hydro Flask reward is on the way.”
These push notifications reinforce the connection between using your card and getting rewarded, which drives more transactions. Plus, they’re a natural moment to surface other offers.
A short “Tap to see more offers” line at the bottom can drive traffic back to the rewards page.
Signs You’re Sending Too Many Notifications
Unfortunately, there is no universal cadence that works for every cardholder base. Some audiences want a push every time a new offer drops. Others will unsubscribe after the second one. The only way to find out what your audience’s baseline is is to experiment and adjust.
You might be on the side of too many if you see:
- Notification settings changing
- Open rates falling over time
- Uninstall rates ticking up
You might not be sending enough notifications if:
- Redemption rates are flat or declining
- In-app rewards engagement is low
- Email is working better than notifications
Less Is Almost Always More
Push notifications shouldn’t be something cardholders dread. Be thoughtful about your sends and test what works.
Ahead of launch (and really, on a regular basis), preview your app to real users, monitor their behavior, and survey their satisfaction.
According to a May 2026 PYMNTS study, 69% of cardholders say the quality of a credit card’s mobile app influences which card becomes their most used. If they don’t like your app, they won’t use it, and they definitely won’t see your push notifications.
Distribution partners like BM Technologies, Vervent, Grit, and Narmi are already using Kard to power their in-app rewards programs.
With three ways to integrate (API, SDK, or turnkey UX), modern fintechs and FIs can offer differentiated rewards that help them be the card (and app) users want to reach for.
