Price-drop alerts are off until you turn them on. Switch on Price drop alerts under Settings > Notifications to start getting them, and use that same page to manage the other emails Wishpicks sends.
Steps
Go to Settings > Notifications.
Turn on Price drop alerts. It's off by default, so nothing tracks or emails until you do this.
Add or open a wish and track it. On the free plan, tracking works on partner stores; with Plus, you can track any store. See "What is Wishpicks Plus, and what do you get?"
Controlling your emails
The Settings > Notifications page has these toggles:
Price drop alerts — off by default. Turning it off shows a quick confirmation, and you'll stop getting drop emails.
Weekly price recap — a weekly savings summary. This one is part of Wishpicks Plus; on the free plan it's locked behind upgrading. On by default for Plus.
Gift reservations — emails about reservation activity. On by default.
Event reminders — reminder emails tied to a wishlist's event date. On by default.
Product news — occasional product updates. Off by default in many regions.
Common questions
The Price drop alerts switch is the real on/off for those emails — turn it off and they stop. You can also opt out straight from your inbox, since every optional email carries an Unsubscribe link at the bottom.
Event-reminder emails have their own toggle. These are the reminders sent before a wishlist's event date or its creation anniversary. Turn off Event reminders in Settings > Notifications, or open one of those emails and tap the Unsubscribe link at the bottom.
Some emails can't be turned off. Account and Plus emails — like a payment-failed notice or a sign-in link — always come through, because they're about your account, not marketing.
Curious how alerts behave once they're on? See "How do price-drop alerts work, and how often are prices checked?" And if you want to fine-tune when one fires, Plus lets you set a custom threshold or target price — see "How do I set a target price or change when I get a price-drop alert?"
