# Scheduling and audience

# Scheduling & Targeting Contacts

Mailofly allows you to target specific segments of your contacts and automate sends using scheduled or recurring cron configurations.

***

## Contact Targeting

When configuring a campaign, select a target **Segment**:

* **All Contacts**: Sends to every subscribed contact in your audience.
* **Filter Segments**: Sends to contacts matching dynamic criteria (e.g. `plan = pro`, `country = US`, `created_at > 30 days ago`).

> **Suppression Safeguard**: Contacts that are unsubscribed, hard-bounced, or marked as spam complaints are automatically filtered out prior to sending.

## Schedule Types

| Schedule Type                     | Behavior                                                                                             | Plan Level                   |
| :-------------------------------- | :--------------------------------------------------------------------------------------------------- | :--------------------------- |
| **Manual (Send Now)**             | Dispatches immediately upon clicking "Send Now".                                                     | All Plans (Free, Basic, Pro) |
| **Scheduled Once**                | Queues the campaign to start at a specified ISO-8601 date and time.                                  | Basic, Pro                   |
| **Recurring (Whole Segment)**     | Repeats at fixed intervals (e.g. Every 7 days) to the entire segment.                                | Basic, Pro                   |
| **Recurring (New Contacts Only)** | Repeats at fixed intervals, but only sends to contacts that have **not yet received** this campaign. | Basic, Pro                   |

## Timezone Optimization

Scheduled campaigns execute using UTC timestamps. Ensure your desired launch hour accounts for the primary timezone of your recipients (e.g. 14:00 UTC for 10:00 AM US Eastern).
