How to Schedule an Email (Every Major Client)
TL;DR: To schedule an email, write it as usual, then choose the schedule option instead of sending right away: in Gmail and Outlook click the arrow next to Send and pick Schedule send; in Apple Mail click the arrow by Send and choose Send Later; on mobile, press and hold the send button. The largest analysis of email timing, covering about 26 billion emails, found the open-rate gap between the best and worst weekday is only about 1.6 points (Omnisend, 2026), so timing helps less than most people think.
This guide shows you how to schedule an email in every major client: Gmail, Outlook (new and classic), Apple Mail, and on your phone. It is for business owners and founders who write their own email and want a message to land at a sensible hour without staying up to send it. Each section gives the exact menu names from official help docs. At the end, what to do when scheduling one email at a time stops scaling.
How do you schedule an email to send later?
You schedule an email by writing it normally, then choosing a delayed-send option instead of sending immediately. In every major client the feature sits right next to the Send button: a small dropdown arrow opens a menu where you pick a date and time, or accept a suggested slot. The message waits, then sends on its own at the time you set, even if your device is asleep, as long as you have an internet connection.
The mechanics are nearly identical across Gmail, Outlook, and Apple Mail. The label is the only real difference: Gmail and Outlook call it Schedule send, and Apple Mail calls it Send Later. Classic desktop Outlook is the one exception, using an older Delay Delivery option that holds the message in your Outbox. The steps below cover each one.
Before the steps, a useful reality check on when to schedule for. Timing matters, but less than the advice industry suggests.
How do you schedule an email in Gmail?
To schedule an email in Gmail on a computer, write your message, then click the down arrow next to Send in the bottom left and choose Schedule send. Gmail offers a few suggested times or lets you pick a custom date and time. The email moves to a Scheduled folder and sends automatically at the time you set, based on the time zone you scheduled it in.
Step by step, on desktop:
- Open Gmail and click Compose in the top left.
- Write your email.
- Next to Send in the bottom left, click the down arrow (More send options).
- Click Schedule send, then pick a suggested time or set a custom date and time.
To change or cancel a scheduled message, click Scheduled in the left panel, open the email, and click Cancel send in the top right. Gmail turns it back into a draft you can edit and reschedule. You can hold up to 100 scheduled emails at once, and delivery may land a few minutes after the exact time.
How do you schedule an email in Outlook?
Outlook has two different paths depending on which version you run. New Outlook and Outlook on the web use Schedule send, the same idea as Gmail. Classic Outlook for Windows uses an older Delay Delivery option that holds the message in your Outbox, which means the app must be open and online when the send time arrives.
In new Outlook or Outlook on the web:
- Compose your message.
- Click the dropdown arrow next to Send and choose Schedule send.
- Pick a suggested time or set a custom one, then select Send.
The message stays in your Drafts folder until it goes out. To send it sooner, open the draft, click the Edit pencil, and choose Send Now. Note that Schedule send is not available for IMAP or POP accounts in new Outlook.
In classic Outlook for Windows, for a single message:
- While composing, select the More options arrow in the Tags group on the ribbon. (On the simplified ribbon, go to the Options tab, then More commands.)
- Under Delivery options, check Do not deliver before and set the date and time.
- Select Close, then Send.
The message waits in your Outbox until then. To cancel, open it from the Outbox, clear the Do not deliver before box, close, and send normally. Classic Outlook can also delay every outgoing message by up to two hours using a rule, which is a useful safety net against the email you regret three seconds after sending.
How do you schedule an email in Apple Mail?
To schedule an email in Apple Mail on a Mac, write your message, then click the arrow next to the Send button and choose a suggested time or Send Later, where you set a custom date and time. The scheduled message moves to a Send Later mailbox in the sidebar and sends on its own at the time you picked, provided you have an internet connection.
On a Mac:
- Write a new email.
- Click the arrow next to the Send button.
- Choose a suggested time, or select Send Later to set a custom date and time.
To change the time, double-click the message in the Send Later mailbox and click Edit in the top right. To cancel it, highlight the message in that mailbox and delete it, which stops the scheduled email from sending. One quirk worth knowing: scheduled Apple Mail messages do not sync across devices, so an email you scheduled on your Mac will not appear on your iPhone.
How do you schedule an email on your phone?
On mobile, the schedule option hides behind a press-and-hold or a menu rather than a visible button. In the Gmail app, compose your message, tap More (the three dots) in the top right, then tap Schedule send and pick a time. In Apple Mail on iPhone, press and hold the send arrow until a menu appears, then choose a suggested time or Send Later to set your own.
A few notes that apply across phones. The Outlook mobile app offers a similar schedule option in its send menu, though exact placement shifts between updates, so look for a clock or schedule icon near send. To manage a scheduled message, find the Scheduled or Send Later folder in the app's mailbox list, open the email, and edit or cancel it there. As on desktop, the device needs an internet connection for the message to go out at the scheduled time.
If your reason for scheduling is simply "not now, but I will forget if I leave it as a draft," mobile scheduling is the fastest fix. Write the reply on your phone, schedule it for the next morning, and it leaves your hands.
Beyond manual scheduling: when one email at a time stops scaling
Scheduling works well for a handful of messages. It breaks down when the job is not "send this at 9 a.m." but "reply to all of these at the right time, in the right order, and chase the ones that go quiet." That is a different problem. Manual scheduling makes you the scheduler. At volume, that is the bottleneck.
The volume is real. The Microsoft Work Trend Index, from a 2025 survey of 31,000 knowledge workers, found the average worker receives 117 emails a day and is interrupted every two minutes during core hours. Hand-scheduling sensible send times for that load is its own full-time task. The point of scheduling, landing a message at a good moment without you babysitting it, is exactly the kind of judgment a good assistant can carry.
This is the lane Raegan is built for. It drafts replies in your voice, decides when each one should go out by reading the context of the thread, and queues follow-ups for the messages that need chasing, all behind an approval gate so nothing customer-facing sends without your yes. You schedule a moment; an assistant schedules a workflow. For the wider picture, see what an AI email assistant is and how to draft emails in your voice.
Follow-up timing is the clearest example. Scheduling sends one email later; chasing a non-reply means tracking who has not answered and queuing the next nudge at the right interval. Our guide to automating email follow-ups covers that loop in full. And because this all runs over your inbox, the same control logic from our AI personal assistant guide applies: prefer a tool that keeps you the last set of eyes on anything that sends under your name.
Frequently asked questions
Can you schedule an email to send at a specific time?
Yes. Every major client lets you set an exact date and time. In Gmail and Outlook, click the arrow next to Send and choose Schedule send, then pick a custom slot. In Apple Mail, use Send Later. The email sends automatically at that time based on the time zone you set, usually within a few minutes of it.
Does a scheduled email send if my computer is off or asleep?
In Gmail, new Outlook, Outlook on the web, and Apple Mail, yes, because the message is queued on the provider's servers and sends from there. Classic Outlook for Windows with Delay Delivery is the exception: it holds the message in your Outbox, so the app must be open and online at the scheduled time for it to go out.
How do I cancel or change a scheduled email?
Open the folder where scheduled messages live: Scheduled in Gmail and Outlook, or the Send Later mailbox in Apple Mail. Select the email, then cancel or edit it. In Gmail, Cancel send turns it back into a draft. In classic Outlook, open it from the Outbox and clear the Do not deliver before box to send it now.
What is the best time to schedule an email for?
For broad marketing sends, mid-morning Tuesday through Thursday is the common default, with Tuesday leading on opens at 31.27 percent in Omnisend's 2026 analysis of about 26 billion emails. But the gap between the best and worst weekday is only about 1.6 points, so for a personal one-to-one email, a normal business hour matters far more than the exact day.
Can I schedule emails on the Gmail or Outlook mobile app?
Yes. In the Gmail app, tap the three-dot More menu while composing and choose Schedule send. In Apple Mail on iPhone, press and hold the send arrow and pick Send Later. The Outlook mobile app has a similar option in its send menu. Manage scheduled messages from the Scheduled or Send Later folder in the app.
Is there a limit to how many emails I can schedule?
Limits depend on the client. Gmail caps scheduled emails at 100 at a time. Most other clients do not publish a hard number for personal use, though provider sending limits still apply once messages actually go out. If you routinely need to schedule large batches at set times, that is usually a sign to move from manual scheduling to an assistant or tool that manages send timing for you.
