Googleカレンダーの通知: what the free tier covers

When reminders stop arriving, the first suspicion is usually the account. Something must be capped because the plan is free. The opposite case leads to the same suspicion from the other direction: too many alerts, all day, and the assumption that a paid tool would sort them out. Both readings start in the wrong place. Event notifications in Google Calendar are not a metered feature. The money in a Google Calendar setup sits somewhere else, and once that line is drawn the list of things worth paying for gets very short.

The notification layer itself is not billed

A Google Account includes event notifications with no upgrade attached. There are two delivery routes. One is the browser route, which splits again into desktop notifications that appear outside the browser window and alerts that appear inside the Calendar page. The other is email. A phone with the Calendar app installed adds push on top of that.

The limits are generous and identical across account types. A single event accepts up to five separate reminders, and each one can be set anywhere from zero minutes to 40,320 minutes before the start. That upper figure is four weeks expressed in minutes, so a reminder a month ahead of a deadline is inside the free range. Per calendar defaults exist for timed events and, separately, for all day events. None of that is gated.

One delivery route did disappear, and it gets mistaken for a paywall. SMS reminders were removed on January 7, 2019. Anyone who had been receiving calendar alerts as text messages saw them replaced by in app notifications and email. The change applied to every account, paid included, so a business plan does not restore it.

What is billed is the seat, not the reminder

The paid product here is Google Workspace, which is priced per user per month and covers a custom domain, admin controls, and higher storage. Published Japanese pricing lists Starter at 800 yen per user per month, Standard at 1,600 yen, and Plus at 2,500 yen, before tax, with a 14 day trial on each and a discount for committing to a year. Local pricing pages differ by country, so the figure to check is the one shown for the billing region rather than a converted number.

What moves between those tiers on the calendar side is not reminder behavior. It is room booking, and the upper settings on appointment booking pages. A reminder set ten minutes before a meeting fires the same way on a free personal account as it does on the most expensive Workspace tier. This matters because the most common support request inside companies, a paid seat that produces no alerts, is almost never a licensing problem.

Room booking has a second condition that the price list does not show. A plan that includes it still produces nothing until an administrator has created the rooms as resources in the admin console. Buying the tier and finding an empty room picker is the normal outcome of skipping that step, and it is an internal task rather than a billing one. The same pattern applies to a trial: the trial period is long enough to confirm that a feature appears in the interface, but not long enough to confirm that the organization has configured it.

Running two Google accounts multiplies the work rather than the bill. Defaults are stored per account, so a personal account and a work account each need their own settings, and no subscription merges the two. That is worth naming before a purchase, because the frustration it produces looks a lot like a product limitation.

The one place where free and paid genuinely differ

Appointment schedules are the exception worth knowing. These are the pages that let outside people pick a slot from published availability.

That single page accepts an unlimited number of bookings, and automatic email reminders to the person who booked are included at no cost. The paid side covers creating more than one schedule, taking payment for appointments, requiring email verification to cut down on junk bookings, attaching a schedule to a secondary calendar, and adding up to 20 co-hosts. Eligible subscriptions include Google One Premium, Google AI Pro, Google AI Ultra, Workspace Individual, Business Standard and Plus, Enterprise Standard and Plus, plus the education and nonprofit tiers.

There is also a subtraction to watch for. Workspace Frontline, Essentials, and older subscriptions that are no longer sold cannot create appointment schedules at all. An organization still running a legacy plan will find the published feature list and the actual screen disagree, which is worth checking in the admin console before any budget conversation starts.

Free and paid, side by side

Capability	Free personal account	Needs a paid subscription
Event notifications, popup and email	Included	No upgrade needed
Reminders per event	Up to 5	Same ceiling
Earliest reminder	40,320 minutes ahead	Same ceiling
Per calendar default reminders	Included	No upgrade needed
Separate defaults for all day events	Included	No upgrade needed
Daily agenda by email	Included	No upgrade needed
Appointment booking pages	One	Two or more
Taking payment for appointments	Not available	Paid tiers
Room search and booking	Not available	Workspace plans

Everything on the paid side of that table is about serving other people, not about remembering something. If the problem statement is that meetings get missed, nothing in the right column addresses it.

Three free settings that usually go unused

Before any spending decision, there are three levers already included that most calendars never touch.

The first is the general notification group, which is separate from event reminders. New invitations, changed events, canceled events, responses from guests, and a daily agenda each have their own delivery setting, choosing between email and nothing. Someone drowning in per event popups often gets more out of turning most of them off and taking a single morning agenda email instead.

The second is per calendar defaults. A work calendar can default to a popup ten minutes ahead while a company wide shared calendar defaults to no reminder at all. Applying one default to every subscribed calendar is what makes alert volume scale with the number of events on screen rather than with the number of things that need action.

The third is that all day events carry their own default, set independently. Deadlines, travel days, and renewals have no start time to be early for, so a reminder at the moment the day begins arrives too late to change anything. Moving all day defaults to the previous evening changes what those alerts are worth without changing how many arrive.

What no plan will fix

Missing notifications usually trace to the layers underneath the account. Desktop notifications depend on the browser, and they require Google Calendar to still be open in a browser tab. Permission matters too: if the browser was never allowed to show notifications from calendar.google.com, nothing appears. Snoozing a notification works only in Chrome.

Below that sits the operating system. macOS decides per app whether notifications are allowed at all, whether they appear as a banner that clears itself or an alert that stays on screen, whether they collect in Notification Center, and whether a sound plays. A Focus adds another gate. Time sensitive alerts only break through a Focus if that Focus has been configured to let them, which is set in Focus settings rather than in the app.

Results also vary by machine on the same account. A work laptop that shows reminders and a home Mac that shows none is normal, because browser permission and system notification settings are stored per device. That is the shape of the problem to check first, and it costs nothing to look at.

How a paid calendar app usually structures its price

If the conclusion is that a different calendar is worth paying for, the listed number is only part of what is being agreed to. Pricing on the Mac side tends to take one of three shapes. A one time purchase buys a numbered version, and a later major version is a separate purchase. A subscription bills monthly or yearly, and when it lapses the app either stops opening or drops back to a reduced mode. A hybrid sells a perpetual license bundled with a fixed window of updates, after which the app keeps running on the last version it received.

The second question is what a single license covers. Some licenses follow the person across every Mac they sign in on, others are counted per machine. Family Sharing applies only when the developer has enabled it and only to apps sold through the App Store, so a license bought directly from a developer site follows that site's own terms instead. Where the purchase was made also decides the refund path, since App Store purchases go through Apple's own request flow and direct purchases go through whatever the developer provides.

The trial matters more here than it does for most software. The failure being evaluated is a reminder that did not arrive, and that cannot be observed in ten minutes of clicking around. A trial needs to cover at least one ordinary week, including a day with travel between appointments and a day worked away from the usual machine. A free tier with no time limit is easier to evaluate properly than a seven day full trial, even when the free tier is missing features.

One more line item hides in sync. An app that keeps its own copy of the calendar on a developer run server may require a separate account with its own terms. An app that reads an existing Google account directly adds nothing further to buy, and the account already in place carries the data.

Four things to check on a paid app besides the price

If the answer really is a different calendar, price is the last thing to compare. Four facts change what a listed price means.

The first is whether the product is still being developed rather than merely still downloadable. The second is whether new signups are open, since some tools continue serving existing customers while quietly closing the door. The third is whether ownership has changed, because an acquisition frequently precedes a change in how a tool is licensed. The fourth is whether a pricing change has been announced, in either direction, including moves between a subscription and a one time purchase.

All four can be confirmed in a few minutes from a release notes page and a pricing page. Two tools at the same price with different answers to those questions are not comparable products, and the cost of choosing wrongly shows up later as migration work rather than as a line on an invoice.

What to change first

Spend one week counting two numbers: how many event notifications arrive, and how many of them changed what happened next. If the gap is wide, the fix is free and lives in per calendar defaults. If instead the recurring problem is not knowing which calendar an event is on, reminders were never the issue, and the question becomes whether everything can sit in one window. The Features page covers what that looks like in practice, Compared with other calendars lays out the differences without the sales angle, and Caltimate lists what it costs.
