FollowUpThen vs Queryable

FollowUpThen is an email reminder service that schedules a follow-up when a date or time is placed before its email address. It handles intervals, specific dates, and recurring reminders. Adding it in BCC keeps a reminder private to the sender; adding it in CC sends the due follow-up to everyone in the email's To field. Upcoming reminders can be managed in a web app, by emailing [email protected], or through a daily agenda. The basic reminder workflow does not require inbox access. Listed add-ons include response detection, SMS notifications, persistent tasks, and automatic cancellation when a reply arrives. The service also lists Zapier connections and Google Calendar features. Its free plan allows 50 active follow-ups per month. The Base Plan costs $5 a month, and a 14-day trial is listed. It is available on Android, iOS, and the web; the email-based workflow also works on phones, PCs, and tablets. The service describes encrypted message storage and a privacy mode that deletes message bodies and attachments when a reminder is scheduled.
