How to Set Up Reddit Alerts for Posts and Comments

To get alerts for activity on your Reddit account, sign in and open Settings > Notifications on desktop, then enable the activity types you want. In the Reddit mobile app, open your profile menu, go to Settings > Manage notifications (the intermediate labels can vary by app version). For email alerts, configure the relevant categories separately in your email preferences.

There are important limits: Reddit documents alerts for direct comments on your own post, but not replies to another person’s comment in that discussion. Moderator notifications are configured separately, and Reddit search helps you find matching posts or comments but is not documented as a recurring keyword-alert service.

Choose the alert that matches what you want to follow

Goal	Where to set it up	What to expect
Activity tied to your account	Account notification settings	Choose the available notification types. Coverage depends on the selected type.
Activity delivered by email	Email preferences	Enable the relevant activity categories; email preferences are separate from in-app or site notification settings.
New posts or posts with comments in a community you moderate	Community Mod Tools > Mod Notifications	Moderator notifications have rate limits and exclusions.
Posts or comments matching a topic	Reddit search	Search helps locate existing content. The reviewed Reddit documentation does not establish a general recurring keyword-alert feature.

Turn on personal notifications on desktop

Sign in to Reddit.
Open Settings and select the Notifications tab.
Review the available notification types and enable the ones relevant to your account and posts.
If you want email delivery, also review your email preferences and turn on the relevant activity categories.
Return to Reddit and check that your browser or device allows notifications if you expect push alerts. Reddit’s account settings control which notification types are enabled; browser and operating-system permissions govern whether a device can display them.

Reddit’s settings page exposes notification controls and configurable availability periods. The exact controls can change, so use the labels currently shown in your account. [Manage notifications]

Turn on notifications in the Reddit mobile app

Open the Reddit app and tap your profile avatar or menu.
Open Settings, then the account settings area.
Choose Manage notifications. On Android, Reddit’s documented route places it under Contact settings; on iOS, the route also goes through account settings. Labels may differ by version.
Enable the notification types you want.
Check the phone’s system notification settings for Reddit if alerts are enabled in the app but do not appear on the device.

Reddit’s Android and iOS help material describes notification management through account settings; follow the current labels in your app if they differ slightly. [Android notification settings] [iOS notification settings]

Get alerts when someone comments on your post

Enable the relevant post or comment activity notification in your account settings. Reddit’s documented alert covers a comment made directly on your post, also called a parent comment. It does not cover someone replying to another person’s comment in that post’s thread. If you need email delivery too, enable the matching activity category in email preferences. [Comment alert coverage]

This distinction explains many apparently missing alerts: a reply can appear in the discussion without being a direct comment on your post. For a conversation with nested replies, revisit the post or use Reddit’s available thread and inbox views rather than assuming every reply will trigger an alert.

Configure email activity notifications

Open your Reddit account’s email preferences.
Review the activity categories available to you.
Enable the categories you want, such as mentions, follows, upvotes, replies to comments, or comments on posts, where offered.
Confirm the email address on the account and check spam or filtered folders if messages do not arrive.

Email activity is configured separately from other notification settings. The categories available in your account determine what Reddit can send, so check the current preference list instead of expecting every type of activity to be emailed. [Reddit email notification preferences]

Set moderator notifications for a community

If you moderate a subreddit, use its separate community notification controls:

Open the community’s Mod Tools.
Go to Mod Notifications.
Enable New Posts, Posts with comments, or both, depending on what you need to monitor.
Review the community settings periodically if your moderation workflow changes.

These alerts are subject to rate limits, and Reddit documents exclusions, including posts older than seven days. Treat them as useful signals rather than a guarantee that every eligible event will produce a notification. [Reddit Mod Notifications]

Find topic matches with Reddit search

For a keyword or topic, search Reddit to find matching posts and comments. Scope a search to a community or use filters such as subreddit:, author:, title:, and selftext:. For example, search for subreddit:cats to narrow results to that community, or combine a scope with a term such as title:cats. Reddit also documents searching comments within an individual post. [Reddit search features]

Search is for locating content. The official search documentation reviewed for this guide describes search and filters, not a general system that repeatedly checks a query and sends alerts. Do not assume that saving a search or running one once creates recurring notifications.

When to use each route

Your own posts or account activity: account notifications, with email preferences added if you want email.
Replies to your comments: enable relevant account activity and email categories, then remember that direct-post comment alerts and nested replies have different coverage.
A community you moderate: Mod Notifications for new posts or posts with comments, with rate limits and exclusions in mind.
A topic across Reddit: search for current matches; the reviewed documentation does not verify recurring keyword alerts.

Troubleshooting missing Reddit alerts

Symptom	Likely cause	What to check
No alert for a nested reply	The reply was to another person’s comment, not directly to your post.	Reddit documents direct parent-comment alerts, not alerts for replies to someone else’s comment. Check the thread directly.
Notifications are enabled but no phone push appears	The app setting may be on while device-level notification permission is off, or the selected category may not cover the event.	Review Reddit’s notification settings and the phone’s system notification permission.
No email arrives	The relevant email category may be disabled, the account email may need attention, or a mail filter may have moved the message.	Review email preferences, verify the address, and check spam and mail rules.
Moderator did not receive an alert	Rate limits or an exclusion may apply.	Check Mod Notifications settings and remember that Reddit lists limits, including an exclusion for posts older than seven days.
A search query did not send an alert later	Search finds content but is not documented here as a recurring alert mechanism.	Run the search when you need current results; do not rely on it as a subscription.
Settings labels do not match these steps	Reddit’s app and interface labels can vary by platform and version.	Look under account Settings for Notifications or Manage notifications and consult Reddit Help for your platform.

Performance, reliability, and cost

Reddit’s built-in settings are the direct route for account activity, email, and moderator notifications described above. Their scope is determined by the notification types Reddit offers, the distinction between parent comments and nested replies, and moderator limits. Search is useful for manual discovery but should not be treated as a recurring alert feed based on the reviewed documentation. No third-party monitoring setup is needed for these built-in routes.

Or skip the browser setup

If your work involves documenting Reddit pages rather than receiving Reddit activity notifications, ScreenshotNeo is a website screenshot API and MCP server. It does not configure Reddit alerts. One GET request captures a URL as an image or PDF; see the ScreenshotNeo API documentation.

curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://www.reddit.com -o shot.webp

import requests
r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://www.reddit.com"}, timeout=90)
open("shot.webp", "wb").write(r.content)

const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://www.reddit.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);

ScreenshotNeo accepts cookie or consent banners and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each step can be turned off. Bot checks, blank pages, and failed loads are not billed, and response headers report the page verdict and billing status. Its MCP server provides take_screenshot, get_page_info, and capture_pdf for AI agents. The free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000 shots. Sign up for 1,000 free screenshots a month, no card required.

FAQ

Can I get notified about every comment in a Reddit discussion?

Reddit’s documented alert for your post covers direct comments, not replies to another person’s comment. Check the discussion for nested replies.

Does Reddit search send me a notification when a new keyword match appears?

The reviewed official search documentation describes finding and filtering content, not recurring keyword alerts.

Are moderator alerts the same as personal account notifications?

No. Moderator alerts are configured in a community’s Mod Tools under Mod Notifications and have their own limits.

Can I receive both push and email alerts?

Configure account notifications and email categories separately, then check device permissions for push delivery.
