Why it matters

Multi-channel alerts

An alert that arrives somewhere you don't check might as well not have fired. And an alert channel with no confirmation threshold trains your team to ignore it after the third false page in a week. Both failure modes end in the same place — a real outage that nobody responds to, either because the notification landed in an inbox nobody opens or because everyone's already learned to swipe the page away without reading it. The fix isn't a smarter algorithm, it's picking a channel people actually look at — Slack if that's where your team lives, SMS if it's genuinely urgent — and only paging through it when the failure is confirmed and real, so the alert still carries weight the fiftieth time it fires. It's the same reason a car alarm that goes off for every passing truck eventually gets ignored by the whole street. Getting alerting right isn't about adding more channels — it's about making sure the ones you do use are ones people can't help but notice.

Four channels, every tier

Email, Slack, webhook and SMS, with no add-on pricing gating any of them behind a higher plan. Wire up whichever combination actually reaches your team — email for a paper trail, Slack for where the conversation already happens, SMS for the person who needs to wake up — without an upsell standing between you and the channel that would actually work. It also means there's no reason to settle for a channel that's merely convenient instead of one that's actually effective. Nothing here requires guessing which plan unlocks which channel.

Confirmation threshold

Requires a real, sustained failure before it notifies anyone — a single blip stays quiet. A request that times out once because of a passing network hiccup doesn't page anyone; the monitor waits for the failure to hold across the confirmation window before it decides something's actually wrong and worth interrupting someone for. That threshold is configurable, so the balance between speed and certainty is yours to strike. It's the setting that keeps an alert meaningful instead of just noisy.

Quiet hours, respected

Starter+ SMS/push contacts can set a do-not-disturb window so a 3am blip waits until morning. That's a real trade-off worth making deliberately, not something you have to hack together with a phone's own do-not-disturb settings and hope the timing lines up with your actual on-call schedule. It's a small setting that pays for itself the very first night it prevents a needless page. It's one of the simplest ways to protect a team's sleep without sacrificing responsiveness.

FAQ

Multi-channel alerts, answered.

Will one blip page my team?

No — every alert channel respects a confirmation threshold, requiring a real, sustained failure before anyone is notified, so a single blip stays quiet. That threshold is what keeps an alert meaningful; a tool that pages on the first failed request trains a team to distrust it within the first week. That's true no matter which channel or combination of channels you've configured. The threshold does the filtering so nobody has to build their own workaround for it.

Which alert channels cost extra?

None. Email, Slack, webhook and SMS are all included on every tier, with no add-on pricing gating any channel behind a higher plan. You're free to wire up all four for the same monitor if that's what actually gets someone's attention, without worrying about a per-channel surcharge. It's a deliberate choice — the pricing here isn't built around metering how a customer chooses to be woken up. Every plan gets the full set from day one.

Do I need a separate app for SMS alerts?

No — SMS goes straight to the phone number you add as a contact, configured from the same dashboard as every other channel, with no separate app to install. It arrives like any other text message, so there's nothing extra for whoever's on-call to set up on their own phone. Add or remove a phone number the same way you would any other contact, no extra step involved. Setup takes about as long as saving a new contact in your phone.
