Push Notification Opt-Outs Climb 22% After the Second Deposit Ask
Push opt-out rates at U.S. real-money casino apps rose 22% in the 30 days after a player's second deposit prompt, compared with the 30 days before that prompt, according to a panel of 41,000 iOS and Android users tracked across 14 apps between January and September 2025. The rise is not a one-time blip: it holds across sportsbook, social casino, and slots-first products, and it shows up even among players who had previously kept notifications on for more than a year. The number matters because push is the cheapest re-engagement channel most operators have left, and the second deposit ask is the moment it starts to fail.
What the panel actually measured
The data comes from a device-level panel run by a mid-size attribution vendor that sells to six of the fourteen apps in the sample. Users opted in to share push settings and in-app events in exchange for a small monthly credit. Roughly 41,000 users met the inclusion criteria: at least one deposit, push permission granted at install, and at least 60 days of continuous data.
The 22% figure is a ratio of ratios. In the 30 days before the second deposit prompt, 8.1% of the cohort disabled push. In the 30 days after, 9.9% did. That is a 1.8-point absolute increase and a 22% relative jump. The pattern is cleaner than the headline number: opt-outs spike 48 to 72 hours after the prompt, then settle at a rate about 30% higher than the pre-prompt baseline for the rest of the observed window.
Two caveats worth stating up front. First, the panel skews slightly younger and more iOS-heavy than the average U.S. casino app user base, and iOS users have been more aggressive about disabling notifications since the 2021 Focus modes rollout. Second, "second deposit prompt" is not a standardized event. Some apps trigger it as a push, some as an in-app modal, some as both. The vendor classified a prompt as any message that explicitly referenced a second deposit, a reload bonus, or a "come back and play" offer within seven days of the first deposit.
Why the second prompt, not the first
The first deposit prompt barely moves opt-outs. In the same panel, opt-out rates in the 30 days after a first-deposit welcome message rose 3.4% — within noise for a cohort this size. The second prompt is different because of what it implies. By the time a player sees it, they have already decided whether the product is for them. The prompt is the operator's first real ask, and it arrives at the moment the player is least sure they want to keep hearing from the app.
A separate cut of the data shows the effect is strongest among players who deposited exactly once and never returned. That group accounts for 61% of the post-prompt opt-outs, despite making up 38% of the cohort. Players who made a third deposit on their own — without a prompt — opted out at roughly the pre-prompt baseline.
The push channel is not dead, but it is getting expensive
Push notifications have long been the default retention tool for U.S. casino and sportsbook apps because they are free to send and, until recently, easy to ignore. That calculus is shifting. Apple's 2023 changes to notification summaries and the broader user habit of muting apps rather than deleting them have made the channel noisier. A 2024 industry benchmark put average push opt-out rates for gambling apps at 14% within the first 90 days; the panel here shows 19% over a comparable window for apps that send more than four pushes a week.
The 22% figure is a relative increase, not an absolute one, and that distinction matters for anyone building a retention model. An operator with a 12% baseline opt-out rate should expect something closer to 14.6% after the second deposit prompt, not 34%. The absolute number stays small. The direction does not.
What is less clear is whether the prompt causes the opt-out or merely correlates with it. Players who are already drifting away are more likely to see a second deposit prompt, because the prompt is often triggered by inactivity. The vendor tried to control for this by comparing players who received the prompt within 48 hours of their first deposit against a matched group who received it later. The early-prompt group opted out at 9.4%; the late-prompt group at 10.1%. The gap is small, which suggests timing is not the main driver. The act of asking is.
The reload bonus problem
Second deposit prompts are almost always tied to a reload bonus, and reload bonuses carry wagering requirements that are frequently worse than the welcome offer. A typical U.S. market reload might be a 50% match up to $200 with a 10x rollover on the bonus amount, compared with a welcome offer of 100% up to $1,000 at 15x. Players who did the math on the first offer and found it marginal are unlikely to be persuaded by a worse one. The push that delivers it becomes the moment they decide the app is not for them.
Operators know this. Several of the apps in the panel have quietly moved second deposit prompts from push to in-app messaging, where the opt-out cost is zero. Others have started suppressing the prompt entirely for players who have not opened the app in 14 days, on the theory that a push to a dormant user is more likely to trigger a mute than a deposit.
What the opt-out data looks like by product
| Product type | Pre-prompt opt-out (30d) | Post-prompt opt-out (30d) | Relative change |
|---|---|---|---|
| Sportsbook-first | 7.2% | 8.6% | +19% |
| Slots-first casino | 8.8% | 10.9% | +24% |
| Social casino (no cash out) | 9.1% | 11.4% | +25% |
| Poker/table | 6.4% | 7.5% | +17% |
Sportsbook apps show the smallest relative increase, likely because their push cadence is already tied to game schedules and users expect more messages. Poker and table apps show the smallest absolute numbers, consistent with a smaller, more committed user base. Slots-first casino apps — the category most dependent on push for daily active user numbers — show the largest hit.
The social casino row is the one worth pausing on. Social casino apps do not have real-money deposits, so the "second deposit prompt" in that category is actually a second virtual coin purchase prompt. The opt-out pattern is nearly identical. That suggests the effect is not about money specifically but about the perception of being asked twice for something the user did not fully opt into the first time.
A note on the 41,000-user sample
Panel-based measurement has known weaknesses. Users who agree to share device data are not representative of the general population, and attrition in the panel is highest among exactly the users most likely to opt out of push. The vendor reports a 12% monthly churn in panel participation, which means the 22% figure may understate the true rate. A separate, smaller study using server-side opt-out logs from two operators — not included in the panel — showed a 27% relative increase over the same window, though the sample was only about 6,000 users and the confidence interval is wide.
The honest read is that the true number is somewhere between 18% and 27%, and the direction is not in dispute.
Why this matters more in the U.S. than elsewhere
U.S. operators have fewer re-engagement channels than their European counterparts. Email deliverability for gambling brands is poor, SMS requires explicit consent that most users never give, and app store rules limit what can be done with in-app messaging for users who have not opened the app. Push is the last low-friction channel, and it is degrading.
At the same time, U.S. customer acquisition costs have climbed. Several public operators reported CPA in the $400 to $600 range in mature states during 2024, and retention spending has grown faster than acquisition spending for the first time since legalization. A 22% increase in opt-outs after the second deposit prompt is not a crisis on its own. Combined with rising CPA and a smaller addressable pool of first-time depositors in states that have been legal for more than three years, it is a structural problem.
The regulatory angle is minor but real. Some state regulators have started asking about promotional messaging frequency as part of responsible gambling reviews, and a documented link between aggressive deposit prompts and opt-outs gives those reviews a concrete metric. No state has proposed a cap on push frequency for gambling apps, but the data here is the kind of thing that shows up in a comment period.
What operators are actually doing
Three responses show up repeatedly in the panel data and in conversations with retention leads.
The first is to stop calling it a "second deposit" prompt. Apps that framed the message as a game update, a leaderboard reset, or a free-spin drop saw opt-out increases of 9% to 12% instead of 22%. The deposit still happened; the framing changed.
The second is to move the prompt to a channel where opting out is harder. In-app inboxes and web-based account pages have no push permission to revoke. The tradeoff is lower open rates, but the opt-out cost is zero.
The third, and least common, is to stop sending the prompt at all and let the player come back on their own. One operator in the panel removed second deposit prompts entirely in March 2025 and saw a 4% decline in second-deposit conversion over the next quarter, offset by a 16% reduction in push opt-outs. The net effect on revenue was roughly neutral, which is not the result most retention teams expect.
The open question
The data says players opt out of push after the second deposit ask. It does not say whether they would have opted out anyway, or whether a different ask at a different moment would have kept them reachable. The vendor's matched comparison suggests the ask itself is the trigger, but the sample is small and the panel has the usual self-selection problems.
What is clear is that the second deposit prompt is no longer a free action. It has a measurable cost in channel access, and that cost is rising. The operators treating push as an unlimited resource are the ones losing it fastest. The ones treating it as a budget — spent carefully, on players who have shown they want to hear from the app — are keeping it longer.
The question worth asking is not whether to send the second deposit prompt. It is whether the prompt is worth the push permission it costs. For a player who deposits $50 and never returns, the answer is almost certainly no. For a player who deposits $500 over six months, the math is different. Most operators do not segment that finely before they send. The 22% number is what happens when they do not.
