# Send Options
> Four ways to time a send: right away, at a scheduled time, inside delivery windows, or ramped gradually to warm up a domain.
When you send an [Email](/create-emails/emails), the **When to send** step offers four options:
| Option | What it does | Reach for it when |
| -------------------- | ------------------------------------------------ | ------------------------------------------------------ |
| **Send now** | The email goes out right away. | The email is ready and timing doesn't matter. |
| **Schedule** | Sends automatically at a date and time you pick. | You know the exact moment you want. |
| **Intelligent send** | Delivers inside time windows you set. | You care more about when it lands than when it leaves. |
| **Gradual send** | Ramps daily volume over several days. | You're warming up a new or low-volume domain. |
Send now and Schedule work the way you'd expect. The two newer options have settings worth knowing about.
## Intelligent Send
Intelligent send delivers inside one or more time windows instead of at a single moment.
Pick a preset (Morning commute, Mid-morning, Lunch break, Early afternoon, Post-work, Evening) or set your own window with the timeline and time fields, for example 09:00 to 11:00. Click **Add window** to deliver across more than one window; recipients are spread across all the windows you set. If a window has already passed today, those recipients get the email tomorrow instead.
Windows follow the timezone in the **Times in** selector, so a 09:00 to 11:00 window in America/New York lands mid-morning for an East Coast audience no matter where you are when you hit send.
### Per-Recipient Intelligence
Intelligent send includes a **Per-recipient intelligence** toggle. Turn it on and Brew sends to each contact at their usual open time, based on their engagement history. Contacts without enough history use your windows, same as a regular intelligent send.
## Gradual Send
Gradual send ramps up daily volume instead of delivering to the whole audience at once. Use it to warm up a domain that is newly verified or has been sending at low volume. It works for your regular marketing and customer sends, so you don't need a dedicated warmup campaign to build reputation.
You control the ramp with four settings:
* **Start**: begin right away or pick a date and time for the ramp to start.
* **Starting volume**: how many emails go out on day one. Brew recommends 50.
* **Increment**: how much the daily volume grows. The recommended 1.25x grows volume 25% each day.
* **Safety threshold**: when Brew should pause the send. The recommended Balanced threshold pauses if bounces exceed 3% or complaints exceed 0.07%. You get an alert if sending pauses, so you can investigate before resuming.
As you adjust the settings, the **Daily send schedule** chart shows how many emails will go out each day.
Sending from a brand-new domain? [Verify it](/get-started/verify-your-sending-domain) first, then use gradual send for your first sends so the domain builds reputation cleanly.
## When You Launch an Automation
Launching a [manual-audience automation](/create-emails/automations#manual-audience) run goes through a similar picker with three options: **Run now**, **Schedule**, and **Gradual send**. Intelligent send isn't offered for automation runs; timing inside a flow comes from its Wait steps.
