Thunderbird is a free desktop email client app that is capable enough to handle business use. It comes with features you usually find on paid tools such as Outlook and Mailbird. One of which, Thunderbird allows you to set a follow-up reminder. This feature is crucial enough if you use email for business.
You can make use of the task management feature of Thunderbird to set a follow-up reminder. When turning an email into a task, you can set a reminder to make sure you are not going to miss it once the time comes.
Setting up a follow-up reminder in Thunderbird
To be honest, setting up a follow-up reminder in Thunderbird is a bit hassle as you will see no follow-up option near the send button like when you are setting up a reminder in Gmail using Boomerang or Gmelius. You need to go to the Sent Mail folder to select an email you want to set the follow-up reminder of.
First off, create a new email just like usual by clicking the Write button on the toolbar or use the keyboard shortcut by pressing the Ctrl+N keys on the keyboard. Send this email.
Once the email is sent, go to the Sent Mail folder and select the email you want to set the follow-up reminder of, right-click and select Convert To -> Task.
Give your task a title on the Title field to make easy for you to identify it later. Set the category to Follow up. Also set the start date as well as the due date. To set the reminder, you can go to the Reminder option. Click Save and Close once you are done making the settings.
Alternatively, you can also use an add-on to set a follow-up reminder in Thunderbird. Unfortunately, it’s hard enough to find a follow-up add-on in Thunderbird. There is one called Follow Up, but it is not compatible with the newer versions of Thunderbird (at least at the time of writing). Probably the developer has stopped maintaining it. You can see the list of the tasks you created on Thunderbird via the Task tab by going to Events and Tasks -> Tasks (Ctrl+Shift+D).
