FollowUpThen
Email-based reminder and follow-up assistant that schedules followups by emailing a date address like tomorrow@followupthen.com.
FollowUpThen does one thing: it turns your inbox into a reminder queue without an app, an extension, or an inbox connection. The email-a-date-address mechanic is genuinely frictionless, and the Skills are the interesting part — Auto-Cancel and Response Detection mean a sales followup quietly removes itself the moment the prospect replies, and Persistent Task keeps nagging until the item is closed. Base at $4/month covers unlimited followups plus the premium Skills, and Team at $4/user/month adds per-member skill budgets and centralized billing. It is the wrong tool if you want a visual board, shared task lists, or a native mobile app. If you want that, look at Todoist or Asana instead — and

About FollowUpThen
FollowUpThen is an email-native reminder and follow-up assistant. You schedule a reminder by sending an email to a date-based address — put the date before the @ sign (tomorrow@followupthen.com, nextmonday@followupthen.com, 3days@followupthen.com) and it bounces back into your inbox then. There is nothing to install and no inbox connection required, so it works from your existing email client on any device where you read email. Natural language date parsing supports thousands of date formats. Skill Add-Ons extend a plain reminder into something closer to an assistant: Auto-Cancel kills a followup when the thread gets a reply, Response Detection cancels if you receive a reply, Memorize runs spaced repetition, and Persistent Task keeps following up until the item is done. Recurring followups, SMS notifications, attachments (Base plan), a list view of upcoming followups, address autocomplete, and group reminders controlled through the To, CC and BCC fields round out the feature set. Google Calendar and Zapier (4000+ apps) are the two documented integrations. Data is encrypted and the vendor states it is used only for productivity. It has been running for over 12 years and reports 30 million followups sent. It fits sales professionals, freelancers, and inbox-centric knowledge workers; it is a poor fit if you need boards, shared task lists, or a native mobile app with push notifications.
Behind the Verdict
FollowUpThen's pitch is that the best reminder tool is the one you already have open. There is no app to install, no inbox to connect, no browser session to remember — you write an email to a date-shaped address and it comes back to you when that date arrives. That constraint is also the product's identity, and it has held for over 12 years with 30 million followups sent, which is a long time for a utility that does not try to become a workspace. Where it earns its place: natural language dates. You type what you are thinking — '3 days', 'next Monday', 'tomorrow' — and thousands of date formats are supported, so you never open a picker. Autocomplete finishes the address for you. Group and private reminders are handled by the To, CC and BCC fields rather than a permissions model, which is about as low-friction as sharing a reminder can get. You can BCC yourself on a group thread to keep the reminder private, or CC others to make the followup visible to them. The Skills are what separate it from a plain snooze button. Auto-Cancel cancels a followup on the same thread when a reply lands. Response Detection cancels if you get a reply from anyone. Memorize applies spaced repetition to whatever you keep forgetting. Persistent Task repeats the followup until it is actually done, which is the closest thing here to a task that refuses to be ignored. Recurring followups handle the weekly status report or the annual anniversary note. SMS notifications cover the case where you are away from email. The honest constraints: this is a reminder service, not a project manager. There is no board, no shared task list, no assignment model, and no Kanban. Collaboration happens through email headers, which is elegant for two or three people and useless for a team that needs to see who owns what. Anyone wanting a visual interface or a native mobile app with push notifications will find the email-only surface spare. Deeper automation means going through Zapier rather than building inside the product. Base at $4/month and Team at $4/user/month are the paid tiers, with a free tier capped at 50 active reminders per month. Where it fits: sales professionals who need a three-day prospect followup that cancels itself on reply, freelancers juggling client threads, and knowledge workers who treat the inbox as the work queue. Where it does not: teams that need shared views and workloads, and anyone whose reminders are really tasks with dependencies. For those, Todoist or Asana; for calendar-shaped reminding, your calendar.

Real-world workflow fit
Concrete scenarios for the personas FollowUpThen actually fits — and what changes day-one when you adopt it.
After a discovery call you send a followup to 3days@followupthen.com with Auto-Cancel enabled, then move on to the next account.
Outcome: The nudge lands in your inbox three days later if the prospect is silent, and disappears on its own the moment they reply, so you never chase someone who already answered.
You set a recurring followup for every Friday to invoice outstanding clients, and a Persistent Task on the one client who has owed you for a month.
Outcome: The Friday invoice reminder repeats without you re-creating it, and the unpaid client keeps resurfacing until you mark the item done.
You BCC tomorrow@followupthen.com on a group thread so the reminder stays private, and use Memorize on the key points you need before a Monday presentation.
Outcome: The reminder comes back only to you, and the spaced-repetition followups land at intervals that actually make the material stick.
Use Cases
- Send a follow-up email to a prospect three days after a meeting, auto-cancelled if they reply.
- Remind yourself to review a document next Monday at 10am using a natural-language date address.
- Set a recurring followup for weekly status reports every Friday.
- Use Auto-Cancel so a followup disappears the moment the recipient answers.
- Run Memorize spaced repetition on key points before a presentation.
- Track a support ticket with Persistent Task so the followup repeats until it is marked done.
- Set a private reminder via BCC for a group meeting without others seeing it.
- Send yourself an annual recurring reminder, such as an anniversary photo to your spouse.
Limitations
- FollowUpThen is deliberately email-only: you create followups by emailing a date-based address, so it needs no inbox connection or installation and works wherever you read email.
- That same design means no visual board, no shared task list, no assignment model, and no native mobile app with push notifications.
- Collaboration runs through To, CC and BCC rather than a permissions model, so it does not scale to teams that need to see who owns what.
- Deeper automation goes through Zapier rather than something built into the product.
- The free tier caps you at 50 active reminders per month, and attachments, calendar feed and Email-Based Actions sit on the Base plan rather than free.
- No underlying AI model is named anywhere in the evidence.

Where the pricing makes sense
The company stage and team size where FollowUpThen's pricing actually pencils out — and where peers do it cheaper.
FollowUpThen sits at the low end of the reminder-tool market: Free at $0/month for up to 50 active reminders, Base at $4/month for unlimited followups plus premium Skills, and Team at $4/user/month with per-member skill budgets, centralized billing and team data ownership. Solo users and small teams get full functionality for a few dollars a month, well under what a full project-management seat costs.
Setup time & first value
How long it actually takes to get something useful out of FollowUpThen — broken out by persona, not the marketing-page minute.
Solo users: about two minutes — there is nothing to install, no inbox to connect, and you send your first reminder to a date address immediately. Teams: plan on ten to fifteen minutes to set up per-member skill budgets and centralized billing on the Team plan, since members still just email date addresses.
Switching to or from FollowUpThen
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a calendar reminder habit: keep the calendar, but send anything that is about a thread to a date address instead — Auto-Cancel handles the reply case a calendar cannot.
- →From a task manager: forward the emails you would have turned into tasks to date addresses, and use Persistent Task for anything that must not be dropped.
- →From email snooze features: replace the snooze with a FollowUpThen date address when you want the followup to survive a client switch or device change.
- ↗To Todoist: export the items that are really multi-step tasks with owners, and keep FollowUpThen only for thread-level nudges.
- ↗To Asana: move anything requiring shared boards, assignments or dependencies, since FollowUpThen has no shared task list.
- ↗To your calendar: move recurring time-based events there, leaving FollowUpThen for reminders that are attached to email threads.
