@fut.io: Our short domain @fut.io is also a great way to save on keystrokes. It works just like the full domain (for example, 1week@fut.io, tomorrow2pm@fut.io, etc only shorter!


To, Cc and Bcc

You can use FollowUpThen in the "Cc", "Bcc" or "To" fields of your email. Each behaves differently:

  • TO: Only you receive the followup.
  • BCC: Only you receive the followup. (No recipients can see that you are using an email reminder service. Followup includes the original email for reference).
  • CC: Everyone in the 'to' field (up to 15) receives a followup in addition to yourself.

Response Detection

Ex: 3weekdays-r@fut.io

Response detection was built to give you peace of mind when emailing forgetful recipients, while at the same time keeping your inbox free from unneeded followups.

Unlike a normal followup a "response detection" followup will be cancelled if a reply has been received. This feature works for both 'cc' and 'bcc' scenarios, depending on if you want the recipient to be reminded, or just yourself.

How to use:

  1. Go to your connected services page and connect FollowUpThen directly with your email inbox. (This is required so that we can monitor your account for replies. More details)
  2. Send an email to someone and place a format such as "1day-r@fut.io" in the 'cc' or 'bcc' field. If they reply before the followup date, the followup will be cancelled.

As mentioned, above this applies to both 'cc' and 'bcc' followups the followup can only be sent to only you, or to your forgetful recipient as well.


SMS Reminders

Ex: tuesday2pm-sms@fut.io

Premium users can add "-sms" to their followups to receive text message reminders. SMS reminders can be combined with tasks and recurring reminders as well. For example:

  • tomorrow1045am-sms@followupthen.com
  • tomorrow1045am-t-sms@followupthen.com
  • everyTuesday3pm-sms@followupthen.com
  • every1500-sms@followupthen.com


Ex: 3weekdays-t@fut.io

This feature is perfect for keeping important tasks at the top of the stack until they're marked as complete. Like your very own, exceedingly persistent, personal assistant.

Unlike normal followups, tasks will continue to followup every 24 hours until marked as complete (or cancelled). Create a task by adding -t to the end of the followup time.

  • 3days-t@followupthen.com
  • friday330pm-t@followupthen.com
  • friday1530pm-t@followupthen.com
  • 1year-t@followupthen.com
  • monday9am-t-sms@followupthen.com

Tasks can be assigned to yourself, or someone else. To assign a task to yourself, use the 'to' or 'bcc' fields. To assign a task to someone else, send them an email and put the format in the 'cc' field.

Here is an example that illustrates what will happen when you assign a task to someone else:

  • To: Reilly
  • Subject: Write blog post about new feature
  • CC: 3days-t@followupthen.com

Result: This task has been assigned to Reilly. Both he and the sender will an email confirming the task which also includes links to complete or cancel it. In 3 days, if Reilly has not yet marked the task as complete, an email will be sent to both Reilly and the sender. At this point, either Reilly or the sender can choose to cancel or complete the task. If both do neither, another reminder will be sent in 24 hours. If Reilly marks the task as complete, the original sender will get a notification. Again, if neither party completes or cancels the task, a 3rd reminder will be sent in 24 hours, and so on.

Note: Tasks does not yet work as recurring reminders.


Calendar Integration

Premium users can view and manage their followups without leaving their calendar.

Calendar integration has been optimized for mobile (iOS, Android, Windows) to quickly manage reminders from anywhere. It will still work on desktop calendars (including Google Calendar), however, different calendar programs treat links differently. Some auto-link email address and links, some do not.

You can check "Disable Action Emails" on your settings page to turn action emails (shown above) into regular links which some calendar programs (such as Google Calendar) may recognize as clickable links.


The calendar feed (available on your calendar page) is in Webcal format, compatible with nearly all modern calendar applications.

Setup instructions vary for each calendar system, but can usually be found by searching for "add calendar subscription in [your calendar program]".


Viewing, Editing & Canceling Followups

Viewing and editing:

Just email pending@followupthen.com. Within a few seconds, you'll receive a return email containing your pending followups, together with links to edit or cancel them.

Premium users can also use manage their followups through a simple web interface.

Canceling shortcut:

There is a handy shortcut to cancel a followup: Simply forward a message later on that thread to cancel@followupthen.com.

This works by searching for followups with matching subjects (minus the "Fwd:", "Re:", etc). If found, we'll cancel it on the spot (and will let you know). If more than one matching followup is found, we'll respond with a list of matching followups. You can decide which to cancel from there.

Prevent Duplicate Followups

Here is a tip: When scheduling a new followup but would like to ensure there isn't a followup already existing on that thread, add cancel@fut.io in the 'bcc' field in addition to your reminder. (Note: We will only auto-cancel reminders if exactly one match is found. Read Viewing, Editing and Canceling Reminders for more)


Email-Based Actions

After enabling email actions on your settings page, clicking on certain FollowUpThen links (ex: postpone) will allow you to perform the action by composing and sending an email instead of loading an external site.

How They Work

These "action emails" let you provide instructions for FollowUpThen without leaving your email, saving you countless seconds of your life that would have otherwise been spent waiting for your browser. These emails work based off of a "key" (random series of characters) at the bottom that tells FollowUpThen what to do.

Unsupported Platforms

Unfortunately not all email programs support this type of "email link". For example, the "Gmail" app on iOS, Mailbox for iOS and some others and some versions of the native Android mail client do not yet allow these actions. If you rely on one of these platforms it might be best to leave this option disabled.

Postpone Buttons

Clicking a "postpone" button will compose a postpone email. Freely change the 'to' field to any FollowUpThen address, and hit send. The followup will be postponed.

Followup Button

This lets you easily re-send your original email to the original recipients with a followup message. Everyone in the 'to' field of the original email will receive the followup (not the 'cc' or 'bcc' fields).

If you write a followup message (in the top-part of the email) it will be added to the original email, just as if you re-sent the original with a followup message. If you don't write a followup message, your default message will be used (which you can set here). The followup emails looks like it is coming from you, with a few minor exceptions. Read the details of what this message looks like or send yourself an example by composing an email to yourself and putting 1min@fut.io in the 'cc' field.
