Show Maintenance & Outage Notices in Emails You Already Sent

Planned maintenance or an unexpected outage? Show the notice inside the emails your customers are already reading.

Reach Customers Where They Are Already Looking

When something goes wrong, customers open the emails they already have: the onboarding guide, the monthly report, the latest product update. A new email about the outage arrives late and adds to the noise.

Sendtric's critical alerts let you switch on a notice inside emails you have already sent, and switch it off again once everything is back to normal.

Example: Scheduled Maintenance for a SaaS Product

Here is how a software company could use critical alerts:

  • Every product email includes a critical alert at the top. While it is off, it is an invisible 1x1 pixel.
  • Before planned maintenance, the team schedules an alert to show during the maintenance window.
  • During an unexpected outage, they switch on a "We're experiencing technical issues" alert from the dashboard.
  • Once it is resolved, the alert switches off and disappears on the next open.

Maintenance and Outage Alerts: What Works

  • Embed the alert before you need it. An alert can only appear in emails that already contain its code. Add it to the top of every template: onboarding, product updates, reports and newsletters.
  • Say what is affected, until when, and where to check. Keep the message short and link to your status page for live updates.
  • Schedule planned work in advance. Set the maintenance window and time zone, so the alert shows only while the work is happening.
  • Update the message as things change. You can edit the alert while it is live, so the latest status reaches everyone who opens an email.
  • Switch it off as soon as you are done. An old warning makes everything look broken. Alerts only count views while they are switched on.
  • Use it alongside direct notices. An alert reaches people who open an email. Customers affected by a serious incident should still hear from you directly.
