Limitations
Our add-on runs solely on Google servers and uses AppScript for all the processing. This imposes certain limitations on how, how many and when reminders are sent. Please get familiar with limitations below before starting out.
Free version limits
The add-on is available in 2 versions - Free and Pro, where Pro enables more features and has no usage limits.
Here’s how they compare:
Free | Pro |
---|---|
✅ Use on multiple sheets | ✅ Use on multiple sheets |
🟡 2 reminders | ✅ Unlimited reminders |
🟡 300 notified rows per month | ✅ Unlimited notifications |
❌ Variables in notifications | ✅ Variables in notifications |
Hours are approximate
When you select to be notified hours before(or after), the actual time when notification is sent can range anywhere between 2 hours to 45 minutes before the specified deadline. It is guaranteed that notification will be sent before the deadline, but the exact time may vary.
Some examples:
- 1 hour before 10 AM, you will get notified between 8:45 AM and 9:15 AM.
- 1 hour before 10:50 AM, you will get notified between 8:45 AM and 9:15 AM.
For highest precision and predictability, it’s best to choose times with 0 minutes for the trigger time, e.g. 10:00 or 14:00 instead of 10:05 or 14:35.
This behaviour is due to Google policy, which limits add-on time triggers to a maximum of once per hour.
Notifications are batched
When there are multiple notifications that need to be sent to the same recipient, the messages will be batched into one. Each message is put on a new line.
For example, let’s say you have following sheet data and you have setup an email reminder with content “Hi!”:
Deadline | |
---|---|
01/01/2024 | [email protected] |
01/01/2024 | [email protected] |
01/01/2024 | [email protected] |
01/01/2024 | [email protected] |
In this case John and Alice will receive 1 email each, with following content:
The same behaviour applies to Slack, Discord, Teams and Google Chat integrations.
Google Quotas and Limits
Our add-on is subject to Quotas for Google Services. The limits apply to both Free and Pro add-on users.
