Schedule an Email on Mac: 5 Ways That Work

Scheduling an email on a Mac lets you write a message now and have it sent automatically at a later time. You can do this with the built-in Mail app in macOS Sonoma and later, or with a third-party email client like Microsoft Outlook, Spark, or Airmail. This guide covers the five most practical methods, step-by-step, so you can pick the one that fits how you work.

Why Schedule an Email at All?

Email scheduling is useful for respecting time zones, working outside normal hours, and making sure important messages land at the moment they’ll get the most attention. For example, if you finish a report at 11 p.m., you can schedule it to arrive at 9 a.m. the next business day. It also helps with follow-ups, reminders, and coordinating with teams across the globe. The feature is built into Apple Mail since macOS Sonoma (2023), so millions of Mac users already have it without installing anything.

Method 1: Use Apple Mail’s Built-In Schedule (macOS Sonoma or Later)

Apple added “Send Later� to the Mail app in macOS Sonoma. Here’s how to use it:

1. Open the Mail app and compose a new message as you normally would.
2. Click the chevron (down arrow) next to the Send button (the paper plane icon).
3. Choose Send Later from the dropdown menu.
4. Pick a suggested time (like “Tonight 9:00 PM� or “Tomorrow 8:00 AM�) or click Custom to set your own date and time.
5. Click Schedule.

The email moves to the Outbox folder. You can edit or cancel it before it sends: go to the Outbox, click the message, and choose Cancel Scheduled Send or edit the time. The message will send automatically when the Mac is awake and Mail is running. If your Mac is asleep at the scheduled time, the email goes out when it wakes up.

Method 2: Use Microsoft Outlook for Mac

Outlook for Mac has had scheduling for years, and it works even on older macOS versions. Here’s the process:

1. Compose a new email in Outlook.
2. Next to the Send button, click the dropdown arrow.
3. Select Send Later.
4. In the dialog box, set the date and time you want the email to go out.
5. Click OK.

The email sits in your Outbox until then. Outlook needs to be running at the scheduled time. If you close the app, the email sends the next time you open it.

Method 3: Use Spark Mail

Spark is a popular free email client for Mac that includes scheduling. It works with Gmail, iCloud, Outlook, and most other providers.

1. Compose a message in Spark.
2. Press the clock icon (or “Send Later� button) in the compose window.
3. Choose a preset time or pick a custom date and time.
4. Click Schedule.

Spark sends the email even if the app is closed, because it uses its own servers to deliver at the scheduled time. That’s a big advantage over Apple Mail and Outlook, which rely on your Mac being awake.

Method 4: Use Airmail

Airmail is another Mac email client with a send-later feature. It’s not free, but it has a flexible scheduling system:

1. Compose your email.
2. Click the clock icon in the toolbar (or use the “Send Later� option in the send menu).
3. Set the date and time.
4. Confirm.

Airmail also lets you schedule recurring emails, like weekly reports. Like Spark, it uses server-side delivery, so your Mac doesn’t need to be on.

Method 5: Use a Gmail/Google Workspace Workaround

If you use Gmail in a browser (not the Mac Mail app), you can use Gmail’s “Schedule send� feature. It works on any operating system, including macOS:

1. Compose a message in Gmail.
2. Click the arrow next to the Send button (bottom left).
3. Choose a suggested time or pick a custom date and time.
4. Click Schedule send.

Scheduled emails appear in the “Scheduled� label on the left sidebar. You can cancel or edit them there. This method is reliable because Google’s servers send the email even if your Mac is off.

How to Choose the Right Method

Your choice depends on three factors: your macOS version, whether you want the email to send when your Mac is off, and whether you’re willing to use a third-party app.

• Apple Mail – best if you want a built-in, no-cost solution and use macOS Sonoma or later. It’s fine for most people, but your Mac must be awake at the scheduled time.
• Outlook – best if you already use Outlook for work. It’s reliable but also requires the app to be open.
• Spark or Airmail – best if you need server-side sending (works even when your Mac is off) or want advanced features like recurring sends.
• Gmail web – best if you live in the browser and want maximum reliability.

Common Problems and Troubleshooting

Here are the most frequent issues people hit and how to solve them:

• Email didn’t send at the scheduled time. Check that your Mac was awake and the Mail app was open. If it was asleep, the email goes out when it wakes. For guaranteed delivery, use Spark, Airmail, or Gmail web.
• Can’t find the “Send Laterâ€� option in Apple Mail. Make sure you’re on macOS Sonoma (14.0) or later. Older versions don’t have it.
• I scheduled an email but want to edit it. In Apple Mail, go to Outbox, click the email, and choose “Editâ€� or “Cancel Scheduled Send.â€� In Gmail, go to the “Scheduledâ€� label.
• Scheduled email went out to the wrong recipient. Double-check the recipient field before scheduling. There’s no “undoâ€� after it sends.
• Time zone confusion. The schedule uses the time zone set on your Mac or in your email client. If you’re traveling, verify the time zone in the scheduling dialog.

Frequently Asked Questions

Does Apple Mail schedule emails on older macOS versions?

No. The built-in Send Later feature requires macOS Sonoma (14.0) or later. If you have an older macOS, use a third-party client like Outlook, Spark, or Airmail, or use Gmail in a browser.

Can I schedule an email to send when my Mac is turned off?

Not with Apple Mail or Outlook, because they rely on your Mac being on. Spark, Airmail, and Gmail web use server-side scheduling, so they send even if your Mac is off.

Is there a limit to how far in advance I can schedule an email?

Apple Mail lets you schedule up to a year in advance. Gmail allows up to 49 days. Third-party clients like Spark generally have no strict limit, but check the app’s settings.

Can I schedule an email to repeat weekly in Apple Mail?

No. Apple Mail only supports one-time scheduling. For recurring emails, use Airmail (which has a repeat option) or set up a rule in Gmail with Google Apps Script.

What happens if I delete a scheduled email from the Outbox?

It cancels the scheduled send. The email is moved to Trash (or deleted permanently, depending on your settings) and will not be sent.

Will scheduled emails appear in my Sent folder?

Yes. Once the email is actually sent, it appears in your Sent folder like any other sent message. Before that, it stays in the Outbox or Scheduled folder.
