Keep Event Attendees Informed After You Hit Send with Critical Alerts

Venue changes, weather warnings and new start times don't wait for your next send. Show the update inside the emails your attendees already have.

Event Plans Change. Your Emails Can Too.

Event emails get opened again and again: when tickets arrive, the week before, and on the way to the venue. If something changes after they're sent, a new email has to compete with everything else in the inbox, and the original still shows the old details.

Sendtric's critical alerts let you switch on a message inside emails you've already sent, so anyone who opens them sees the update.

Example: A Festival Weather Update

A festival sends its ticket emails on Monday with a critical alert embedded. While the alert is off, it's an invisible 1x1 pixel that doesn't use any views.

On Friday the forecast turns, so the organizer switches on a weather alert: "Gates now open at 6pm. Bring a rain jacket." Anyone who reopens their ticket email from then on sees the alert at the top.

When the update no longer applies, the alert is switched off, or turns itself off at the end of its scheduled window.

The same festival ticket email shown twice: sent on Monday with no alert, and reopened on Saturday with a red weather update saying gates now open at 6pm

Critical Alerts in Event Emails: What Works

  • Embed it in every event email before sending. Tickets, confirmations and reminders all get reopened, and an alert can only appear in emails that already contain its code.
  • Lead with the change and the action. "Gates now open at 6pm. Bring a rain jacket." tells attendees what changed and what to do in one line.
  • Start from a preset. Severe Weather Warning, Event Cancelled and Event Postponed presets give you a clear, tested layout in seconds.
  • Schedule day-of updates in the event's time zone. Show an entrance change only on event day, and let it switch off once the doors close.
  • Still email everyone about big changes. A cancellation or new date also deserves its own email. The alert makes sure anyone who reopens an old ticket email sees it too.

How to Add a Critical Alert to Your Event Emails

  1. Create a critical alert from a preset such as Severe Weather Warning or Event Postponed.
  2. Paste the code at the top of your ticket and reminder emails before you send them.
  3. When plans change, edit the message and switch it on, or schedule it.

Schedule Alerts Around Your Event

Already know when an update matters? Schedule the alert to switch on and off by itself, in the time zone of your event.

For example, show a note about a changed entrance only on event day, then let it switch off once the doors close.
