# Sending emails

Sending is the runtime counterpart to building email templates. You build the design and metadata once in [Email templates](/help-center/host/creating-email-templates.md), then this is where you actually push them — to your full guest list, a filtered segment, or a single person.

Common patterns:

* **Initial invitation blast** — your invitation template goes out to everyone who hasn't been invited yet
* **Reminder to a subset** — your reminder template goes only to guests who confirmed but haven't downloaded their ticket
* **Resend to a specific guest** — they lost their confirmation, send them another copy
* **Update notice** — venue changed, blast everyone with a notice

You access email sending from the left menu: **Mailing**.

## Bulk mailing — send to many guests at once

This is the primary send surface. It works for everything from "send to everyone" to "send to a single specific person" via the Custom condition filter.

1. Go to **Mailing** in the left menu.
2. Click **New mailing** in the upper right corner.
3. Choose the template you want to send. A summary appears.
4. In the right pane, select your recipients. You have two options:
   * **Pre-defined options** — quick filters like "all confirmed guests," "all guests who haven't responded," etc.
   * **Custom condition** — precise targeting. Examples: "all confirmed guests in Group A," "all guests where their email is X," "everyone who registered after a specific date."
5. (Optional) Click **Edit** to adjust the subject, sender's name, or reply-to email for this send only — without changing the underlying template.
6. Click send.

> The **Custom condition** option is what turns this into a flexible resend tool. To resend to a single registrant, set a condition that matches just them (e.g., `Email → equals → name@company.com`) — works the same as sending to a thousand.

## Sending to a single guest from their record

If your Host setup includes a **Guests** tab in the left menu, you can send directly from a guest's record:

1. Go to **Guests** in the left menu.
2. Click the specific guest you want to email.
3. Click the **Send email** button.
4. Pick the template, then **Send**.

> Some Mobly Host orgs don't expose the Guests tab (the guest list is replaced by Mobly's leads — see the [Host overview](/help-center/host/host.md)). If you don't see a Guests tab in your Host left menu, use the Bulk mailing path with a Custom condition matching just that one guest — same result.

## What gets sent vs. what's stored

The send action uses the template's current state at the moment of send:

* **Template content and design** — whatever's in the Builder right now goes out
* **Subject / sender / reply-to** — pulled from template settings, optionally overridden per-send
* **Attachments** (PDF ticket with QR, ICS calendar file, custom files) — included if configured on the template
* **Visibility conditions on sections** — applied per-recipient, so the same template can render different content to different guests

Once a send goes out, the recipient's record in Host shows that email in their history. If you're using Mobly's CRM-side sync, the engagement also flows there (see the [CRM comparison](/help-center/integrations/crm/comparison.md#activity-logging)).
