Reminders Overview: What are @SaneReminders and how do they work?

SaneReminders notify you when an email you sent wasn’t responded to by a certain time. It’s also an easy way to send a reminder to your future self.

There are 3 different use cases for SaneReminders:

1. Get notified when people don’t reply to you. Say you want to follow up on a lead in a week, but only if you don’t hear back (this is how most people use it). In this case just send the email as usual and CC or BCC a reminder address.

2. You want to defer processing an email (i.e. put back into your Inbox by a certain time). In this case forward that email TO a reminder address and it will show up at the top of your Inbox at the time you specify.

3. Send a reminder to your future self. Just send an email TO a reminder address and it will magically appear at the top of your Inbox at that time.

How to get notified if people don’t reply to you

Put a reminder email address (e.g., etc - more on the options below) in the Cc: Bcc: field. SaneBox will track this email and put it back into the top of your Inbox at the time indicated,unless the email has been replied to.

If you want the reminder regardless of whether or not you got a reply, add the word “keep” to the address (e.g. etc)


  • Send an email To: and BCC:, and if the milk man doesn’t reply by Monday at 10am, we will put that email back into your Inbox, so you can resend it and make sure you get your milk. You can then simply click “reply” and remove the SaneReminders stuff at the top of the email. The milk man will feel horrible about missing the delivery.

How to defer processing an email or send a reminder to your future self

You can setup a quick reminder from your SaneReminders page:

By Email.
If you want to send yourself a reminder or defer processing an email, put the reminder email address (e.g. etc) in the To: field.


  • Send an email To: with the following subject: “Buy flowers for my beautiful wife”. And your Valentine’s Day will be a success.
  • If an email in your Inbox isn’t actionable for 2 more weeks, Forward it to: It will pop back in your Inbox then.

SaneReminder Addresses

Pretty much anything you can think of will work for a SaneReminder address.

  • Minutes, hours, days, weeks, months from now:
    • m = minutes
    • h = hours
    • d = days
    • w = weeks
    • mo = months
    • y = years

You can also write them out – or
You can combine them – means 1 month and 3 days from now.

You can also attach a time to days, weeks and months –

Need to add a week?

Simply use week+1.week. For example, if you want to be reminded next Wednesday, you’ll use

Lastly, you can simply use (which is 24 hours from when you send the email), (which is Monday morning at 2am), or (which is the same date in the next month).

Day of the week:
You can use the full word or a weekday abbreviation – or Your reminder will arrive at the current time on that day. You can also set the hour if you prefer a different time –
Date: or
You may use the month abbreviations – or can set the time as well – (so you don’t miss that champagne toast)!
Time of day: or Receive a reminder at particular time in the next 24 hours – if you send to at 10pm then you’ll be reminded tomorrow at 5pm; if you send to then you’ll get one in 30 minutes. SaneBox does support a 24 hour clock. is the same to us as (Yes, we are respectful of people outside the USA).
Keep: Want to send a reminder that can’t be cancelled by a reply – if you send to then you will be reminded tomorrow even if the person you send the email to replies.

Repeating Reminders

Add each or every to your reminder address and we’ll keep sending you reminders until you receive a reply or cancel the reminder.

  • – receive a reminder at this time every day
  • – receive a reminder every monday morning
  • – receive a reminder every Thursday at this time
  • – receive a reminder every year on April 5th
  • - receive a reminder on the 10th of every month for paying bills and such
  • - receive a reminder on the first wednesday of every month

Addressing Auto-Complete

To make it even easier, we have common @SaneReminders addresses set up for you to download and import to your email client address book:

Save time by adding one of these templated lists to your email client and you won’t have to type them in every time - click the .vcf or .csv link to download.

And here’s an example of what auto-complete will look like:

The @SaneReminders folder

  • After you create your first reminder, we will create a new folder called @SaneReminders. This will hold a copy of the emails that you have requested a reminder for. Please don’t delete these emails.

  • If you do, we will only be able to send you a generic reminder instead of resending the actual email back to your Inbox. Unlike all other Sane folders, please do not rename the @SaneReminders folder.

Why is the reminder still in my calendar?

When the reminder gets replied to or you are reminded, it will still appear on the iCal but for a limited time or a limited amount of reminders. It is 7 days or the last 5 inactive followups, whichever is more. At this time, there’s no configuration to remove the older reminders or fulfilled ones from iCal.

Why did my account get disabled after I sent reminders?

We only allow 50 reminders to be sent per hour.

Resend Reminders

Want us to go the extra mile and remind your recipient to reply to you? Include .resend in your SaneReminder address and we’ll not only remind you that they didn’t reply but we’ll nudge your recipient that you are expecting a reply from them.


What we send you:

What we send the recipient:

Clicking on one of the snooze links in a resent reminder will only snooze the reminder and will not cause us to resend the reminder.

Note for Active Sync Users:

At the moment, if your email server is using Active Sync, you will not be able to use our Sane Reminders feature. We are currently working on a fix for that. We apologize for the inconvenience!

Another Note:

  • If you put the reminder address on the To: line - which indicates to us that you want the email put back in your Inbox at that time for processing. Then, replying to the reminder will snooze the email again.
  • If you put the reminder address in the CC: or BCC: line - which indicates that you only want it in your Inbox if you didn’t receive a reply, then replying should go back to the original recipient.
  • If you want, you can just delete the SaneBox Reminder stuff or leave it to so the recipient knows that they really really do need to reply because SaneBox is like Santa and knows who has been naughty and who has been nice.
  • If you are on our Snack or Lunch plans, snoozing a SaneReminder will not count against your reminder limit for the month. Our Dinner plan allows for unlimited reminders per month so this will not be a concern.
