People rarely unsubscribe because of one notification. They leave because of a pattern. These are ten patterns to avoid, with the fix for each.
1. Asking the moment the page loads
A popup before a visitor has seen anything is easy to dismiss and easy to block. Pick a design that does not cover the page and offer Later. See how to ask for push permission.
2. A vague reason to subscribe
“Enable notifications” says nothing. Say what they will get and that they can turn it off at any time.
3. Fighting your cookie banner
Two prompts at once feel pushy. The plugin waits for the common cookie banners to clear first.
4. Sending too often
If every post, every tweak and every small sale becomes a notification, people stop reading them. Send what you would want to receive.
5. Sending to everyone when a segment fits better
A sale that only applies in one country should not reach the whole world. Filter by country, device, browser, sign-up window or the page people subscribed from, and save the segment to reuse it.
6. Titles that do not say anything
“Update” and “News” tell nobody why to tap. Put the useful part first: “Ten slow-cooker soups for a rainy week”.
7. Linking to the home page
A notification about a specific post or product should open that post or product. Every extra click loses people.
8. Ignoring time zones
A message that arrives at 3 a.m. gets swiped away. Schedule sends for a sensible hour, and aim regional campaigns at a country segment. See when to send.
9. Not checking how it looks on each browser
Chrome, Edge and Android browsers can show action buttons. Firefox and Safari do not, though a tap still opens your link. Use the live preview before you send, and make sure the notification works without the buttons.
10. Letting the list go stale
Dead subscriptions make your numbers look better than they are. The plugin clears them out automatically, so the figure you see is the number of people you can really reach.
The short version
Ask politely, send rarely, aim carefully and make every message worth a tap. For a hands-on start, follow how to add push notifications to WordPress.
