Sending or Scheduling Event Blasts

Learn how to send or schedule Blasts to communicate to guest more about your event.

Blasts are a great way to share more information about your event, such as announcing a special guest, an event update, or a logistical change.

You can send a blast from your event > Manage Event > Blasts tab.

Blasts can only be sent within 7 days after your event ends. After that, you can still reach past guests in other ways — send a newsletter to your calendar subscribers, invite them to your next event, or download your guest list as a CSV and email them directly.

Blasts will be sent via email, SMS, and push notifications. Guests will receive an SMS if they have linked their phone number or a push notification if they have the Luma app. Blasts will also be displayed on the event page for logged-in guests, filtered by each guest’s current status and ticket type. A guest only sees blasts whose recipients match their status at the time they view the page, so a blast sent to “Invited” guests won’t appear on the event page for guests who are going — and an invited guest who later registers will stop seeing it. This also means a guest who registers after a blast went out will see any earlier blasts sent to “Going” guests on the event page, even though they never received them by email.

By default, Blasts are sent to all guests with the “Going” status. On web, the inline composer is limited to 140 characters — great for quick updates and reminders. If you need to send a longer message, customize the recipients, or schedule the Blast, click Advanced.

The Advanced view is only available on the web. From there, you can write much longer messages with no character limit using our Rich Text Editor — including headings, images, buttons, attachments, and event embeds. You can also add a subject line, choose recipients by guest status or ticket type, and schedule when the Blast should be sent.

On iOS and Android, new Blasts are sent as plain text. You can choose who receives the Blast by tapping the recipients at the top of the composer — the same status and ticket type options as on web. To use rich text formatting, add a subject line, or schedule a new Blast, use the Advanced view on the web.

Editing, Rescheduling, and Deleting Blasts

Open a Blast from the Blasts tab to change it:

Edit — Update the subject and message of a scheduled Blast, or of a sent Blast as it appears on the event page. Blasts held for review can’t be edited.
Reschedule — Change when a scheduled Blast goes out. Once a Blast is sent, it can’t be rescheduled.
Delete — Deleting a scheduled Blast cancels it. Deleting a sent Blast removes it from the event page.

Choosing Recipients

Blasts can go to guests by status — Going, Checked In, Pending, Waitlist, or Invited — and, on events with more than one ticket type, be limited to specific ticket types. The two combine: the Blast reaches guests in any selected status who hold any selected ticket type. Invited guests don’t hold tickets, so a Blast to invited guests can’t be limited by ticket type.

You can’t send Blasts to guests marked Not Going. If you need to reach those guests, you can download a CSV of your guest list filtered by that status and email them directly.

Sender Name and Avatar

Who a blast appears to come from depends on the person who sends it:

If the sender is a visible host on the event, the blast is branded as them — their name, their profile photo, and an email address based on their Luma username ({username}@user.luma-mail.com). SMS blasts show their name too.
Otherwise, the blast is branded as the event’s calendar — the calendar’s name, avatar, and {calendar-slug}@calendar.luma-mail.com address. (On personal calendars, it’s branded as the event creator.)

So if you want blasts to always read as coming from your calendar or from one specific person, have that person send them — or make sure other admins who send blasts aren’t listed as visible hosts on the event. You can toggle a host’s visibility in the Hosts section of your event settings.

See Email Delivery + Open Troubleshooting for more on sender addresses.

Colors and Branding

Links, buttons, and accents in the blast email use the event’s theme color, so blasts match your event page. To change how links look in your blasts, change the theme color on the event — there’s no separate link color setting. See Event Themes and Customization.

SMS / Push Notifications

We will automatically send SMS and push notifications to guests once they have verified their phone number and/or downloaded the iOS or Android app.

Texts go to the phone number linked to the guest’s Luma account. If you require a phone number on your registration form, the number a guest enters there is saved with their registration but isn’t texted — a guest who hasn’t linked a phone number to their account gets the blast by email and push only.

Guests can control how they receive blasts (email/SMS/push) via their notification preferences. As a host, you are not able to specify a blast to be sent on a specific channel as that’s a setting guests control.
