Get a Website Change Alert by Email
Most change alerts fail in one of two ways: they email you every time a timestamp or ad changes, or they stay silent because the tool watched the wrong part of the page. RivalPeek.io starts from the change you describe in plain English, shows you what it will watch, and emails you only when that rule matches.
Rules you can type
- “Email me when the price drops below $250.”
- “Email me when this is back in stock.”
- “Email me when the opening hours change.”
- “Email me about new posts that mention pricing.”
- “Email me if the words ‘waitlist closed’ disappear.”
How it works
- Paste the page address and write your sentence.
- Review the rule: the part of the page, what it reads today, and anything it cannot cover.
- Approve it. Checks run every hour on Starter, every 15 min on Pro, every 15 min on Business.
- When a check finds a change that matches the rule, the email goes out right after that check.
What is in the email
The subject line says what happened on which page. The body shows the evidence: the old and new price, the new listings that matched, or the wording before and after. It links to the source page and to the change in your account, where every matching change stays listed with its evidence. Each email also has a “This wasn't useful” link, a quick signal that the rule needs narrowing.
Fewer, better emails
Three settings decide how much email you get:
- The rule. “Any change” on a whole page is the noisiest choice. A price, stock, number or keyword rule fires only on that event. Short self-updating lines such as clocks and “2 hours ago” are ignored in text comparisons.
- The daily digest. Chosen per watch on paid plans and during the trial: instead of an immediate email, its changes wait for one combined email each morning.
- The weekly competitor digest. One email a week summarising changes across the sites you follow, grouped by site.
Folders let you switch email off for a group of watches, for example ones you only review in Slack.
What email alerts cannot do
Checks are scheduled, not live, so a change that appears and disappears between two checks can be missed. RivalPeek.io watches public pages only: nothing behind a login, and no results that only appear after submitting a search form. It sends email, Slack and webhook alerts; there are no SMS or mobile push alerts.
Which plan fits
Email alerts are on every plan. Starter covers 20 pages checked every hour with email alerts, which suits a short list of pages. Pro covers 150 pages checked every 15 min and adds Slack and webhook alerts. Business covers 500 pages checked every 15 min for larger watchlists.

Choose your monitoring capacity
Choose a plan for the pages you need to follow. Starter costs USD $19/month for 20 pages, with ordinary checks every hour. Annual billing is USD $190/year. Pro costs USD $39/month for 150 pages, with ordinary checks every 15 min. Annual billing is USD $390/year. Business costs USD $99/month for 500 pages, with ordinary checks every 15 min. Annual billing is USD $990/year. These are scheduled checks, not a live stream; availability and the check queue can affect when a result arrives.
Pages requiring protected checking use a separate allowance and a slower schedule. Access is not guaranteed, and some sites block automated visits. Start with a representative public URL and review the result before expanding your watchlist.
Frequently asked questions
How many emails will I get?
One email per matching change on a watch. Checks that find nothing new send nothing. For watches that do not need immediate attention, choose the daily digest instead (on paid plans and during the trial): their changes arrive together in one morning email.
Can alerts go to a shared inbox?
Alerts go to the email address on your account, so use a shared address there if a group should see them. For a team channel, Slack and webhook alerts are on Pro and Business and during the trial.
How do I stop alerts from one page?
Every alert email has an unsubscribe link for that watch, which pauses it without affecting your other watches. You can also pause or delete the watch in the app.
Will I be told if a page stops working?
Yes. If a page fails repeatedly over several hours, you get one email saying the watch stopped working, and another when it works again.
