How To Send Reminder Email In Outlook 365 : Automating Follow-Up Reminder Emails

by

Sending a reminder email in Outlook 365 works best when you include a clear subject line referencing the original request. Many people struggle with follow-ups, but learning how to send reminder email in outlook 365 is simpler than you think. This guide covers every method, from manual drafts to automated rules, so you never miss a follow-up again.

Outlook 365 offers multiple ways to remind contacts about meetings, tasks, or pending replies. You can use built-in features like flags, rules, and templates. Each approach saves time and keeps your inbox organized.

Let’s start with the most direct method: writing a reminder email from scratch.

How To Send Reminder Email In Outlook 365

To send a reminder email manually, open Outlook 365 and click “New Email.” Write a subject line that references the original request, such as “Follow-up: Project Deadline Tomorrow.” Keep the body polite and concise. Mention the original date and ask for a confirmation.

Here is a step-by-step breakdown:

  1. Open Outlook 365 and select “New Email.”
  2. In the “To” field, enter the recipient’s address.
  3. Type a subject line that includes the original topic and “reminder.”
  4. Write a short body: “Hi [Name], just a friendly reminder about [original request]. Please reply by [date]. Thanks!”
  5. Click “Send.”

This method works for one-off reminders. But if you send reminders often, you can automate the process.

Using Outlook Flags For Quick Reminders

Flags are a fast way to remind yourself or others. When you flag an email, Outlook adds a visual cue and can send a reminder notification.

To flag an email for a reminder:

  1. Open the email you want to follow up on.
  2. Click the flag icon in the toolbar.
  3. Select “Add Reminder.”
  4. Set the date and time for the reminder.
  5. Click “OK.”

Outlook will show a pop-up reminder at the set time. You can also choose “Flag for Recipient” to send a flag to the other person. This is useful for tasks or deadlines.

Flags are not the same as sending a reminder email. They work inside Outlook but do not generate an email to the recipient unless you choose the recipient flag option.

Creating A Reminder Email Template

Templates save time if you send similar reminders often. You can create a template in Outlook 365 and reuse it with one click.

Here is how to make a template:

  1. Open a new email.
  2. Write the reminder message. Use placeholders like [Name] or [Date].
  3. Click “File” > “Save As.”
  4. In the “Save as type” dropdown, choose “Outlook Template (*.oft).”
  5. Name the template (e.g., “Reminder Template”) and save it.

To use the template:

  1. Click “New Items” > “More Items” > “Choose Form.”
  2. In the “Look In” dropdown, select “User Templates in File System.”
  3. Pick your template and click “Open.”
  4. Fill in the recipient and any placeholders, then send.

Templates ensure consistency. You can create separate templates for meeting reminders, payment reminders, or task follow-ups.

Automating Reminders With Outlook Rules

Rules can automatically send reminder emails based on conditions. For example, you can set a rule to send a reminder when an email is not replied to within 3 days.

To create a rule for reminders:

  1. Go to “File” > “Manage Rules & Alerts.”
  2. Click “New Rule.”
  3. Select “Apply rule on messages I send.”
  4. Choose conditions like “with specific words in the subject” or “sent to a specific person.”
  5. Select actions like “flag message for follow up” or “assign a category.”
  6. Set exceptions if needed.
  7. Name the rule and finish.

Rules do not send emails automatically. They flag or categorize messages. For automatic email sending, you need a macro or third-party tool.

Using Quick Steps For One-Click Reminders

Quick Steps combine multiple actions into one click. You can create a Quick Step that flags an email, moves it to a folder, and sends a reminder email.

To set up a Quick Step:

  1. Go to the “Home” tab and click “Quick Steps” > “New Quick Step.”
  2. Choose “Custom.”
  3. Name it (e.g., “Send Reminder”).
  4. Select actions like “Flag Message” and “Forward.”
  5. In the forward action, type the reminder text.
  6. Assign a shortcut key if desired.
  7. Click “Finish.”

Now, when you click the Quick Step, Outlook flags the original email and opens a forward message with your reminder text. You just need to add the recipient and send.

This method is faster than writing from scratch but still gives you control.

Scheduling A Reminder Email

Outlook 365 lets you delay delivery of an email. You can write a reminder now and schedule it to send later.

To schedule a reminder email:

  1. Write your reminder email as usual.
  2. Click the “Options” tab.
  3. Click “Delay Delivery.”
  4. In the “Delivery options” section, check “Do not deliver before.”
  5. Set the date and time you want the email to send.
  6. Click “Close” and then “Send.”

The email stays in your Outbox until the scheduled time. This is perfect for sending reminders at a specific time, like the morning of a meeting.

Note: Your Outlook must be running at the scheduled time for the email to send. If you close Outlook, the email will send when you open it again.

Using Calendar Reminders For Meetings

If you need to remind participants about a meeting, use the calendar’s built-in reminder feature. You do not need to send a separate email.

To set a calendar reminder:

  1. Open the meeting in your calendar.
  2. Click “Meeting” > “Reminder.”
  3. Choose a time (e.g., 15 minutes before).
  4. Click “OK.”

Outlook will show a pop-up reminder to all attendees. This is the easiest way to remind people about meetings without extra emails.

For more formal reminders, you can send a meeting update with a note. Open the meeting, add a message in the body, and click “Send Update.”

Third-Party Add-Ins For Reminder Emails

If you need advanced features like automated follow-up sequences, consider add-ins. Tools like Boomerang or Mailbutler integrate with Outlook 365.

These add-ins let you:

  • Schedule emails to return to your inbox if no reply is received.
  • Send automatic reminder emails at intervals.
  • Track when recipients open your email.

Most add-ins offer free trials. Check the Microsoft AppSource for options.

Remember, add-ins require installation and may have subscription costs.

Best Practices For Reminder Emails

To make your reminder emails effective, follow these tips:

  • Use a clear subject line. Include “Reminder” and the original topic.
  • Keep the body short. State what you need and when.
  • Be polite. Use phrases like “friendly reminder” or “just checking in.”
  • Include a call to action. Tell the recipient what to do next.
  • Avoid sounding pushy. Give a deadline but offer flexibility.

Example subject lines:

  • “Reminder: Project Report Due Friday”
  • “Friendly Reminder: Meeting Tomorrow at 10 AM”
  • “Follow-up: Invoice Payment Due”

Example body:

“Hi [Name],

Just a quick reminder that the project report is due this Friday. Please send it by end of day. Let me know if you have any questions.

Thanks!”

Common Mistakes To Avoid

Even experienced users make mistakes when sending reminder emails. Here are pitfalls to watch for:

  • Forgetting to change the subject line. A generic subject may be ignored.
  • Writing too much. Long emails are less likely to be read.
  • Using aggressive language. Words like “urgent” or “overdue” can annoy recipients.
  • Sending too many reminders. One or two is enough; more can seem spammy.
  • Not checking the recipient’s time zone. Schedule reminders for business hours.

If you send a reminder and get no response, wait a few days before following up again.

Integrating Reminders With Tasks

Outlook 365 also has a Tasks feature. You can create a task with a reminder that sends an email to yourself or others.

To set a task reminder:

  1. Go to “Tasks” in Outlook.
  2. Click “New Task.”
  3. Enter the task details and set a due date.
  4. Check “Reminder” and set the time.
  5. Click “Save & Close.”

You can assign tasks to others. When you do, they receive an email notification. This works well for team reminders.

To assign a task:

  1. Open the task.
  2. Click “Assign Task.”
  3. Enter the recipient’s email.
  4. Check “Keep an updated copy of this task on my task list.”
  5. Click “Send.”

The recipient gets an email with the task details. They can accept or decline.

Using Categories For Visual Reminders

Categories color-code your emails. You can use them as visual reminders to follow up.

To assign a category:

  1. Right-click an email.
  2. Select “Categorize.”
  3. Choose a color (e.g., red for urgent).

Categories do not send emails, but they help you see which messages need action. Combine categories with flags for better organization.

Mobile Reminders In Outlook 365

Outlook 365 mobile app also supports reminders. You can set flags and receive notifications on your phone.

To set a reminder on mobile:

  1. Open the email.
  2. Tap the flag icon.
  3. Choose a due date.

You will get a notification at the set time. This is useful for on-the-go follow-ups.

Note: Mobile reminders sync with your desktop Outlook if you use the same account.

Advanced: Macros For Automated Reminders

If you are comfortable with VBA, you can write a macro to send reminder emails automatically. Macros require some coding knowledge.

Example macro to send a reminder:

Sub SendReminder()
    Dim olApp As Outlook.Application
    Dim olMail As Outlook.MailItem
    Set olApp = Outlook.Application
    Set olMail = olApp.CreateItem(olMailItem)
    With olMail
        .To = "recipient@example.com"
        .Subject = "Reminder: Task Due Tomorrow"
        .Body = "Hi, this is a reminder about your task."
        .Send
    End With
    Set olMail = Nothing
    Set olApp = Nothing
End Sub

To run a macro, press Alt+F11, paste the code, and run it. Be careful with macros; test them first.

Macros are powerful but can be risky. Always back up your Outlook data before using them.

Tracking Reminder Emails

Outlook 365 can track when your email is read. This helps you know if the recipient saw your reminder.

To request a read receipt:

  1. In a new email, click “Options.”
  2. Check “Request a Read Receipt.”
  3. Send the email.

You will get a notification when the recipient opens the email. Note that recipients can decline to send a receipt.

Read receipts are not foolproof but provide useful feedback.

Organizing Reminder Emails With Folders

Create a folder for sent reminders. This helps you track follow-ups.

To create a folder:

  1. Right-click your mailbox.
  2. Select “New Folder.”
  3. Name it “Sent Reminders.”
  4. Drag reminder emails into the folder after sending.

You can also use rules to automatically move reminder emails to this folder.
