EBS: Everbridge Suite Severe Weather Checklist

This checklist is intended for Severe Weather events that have some lead time before landfall or reaching an area that impacts your people or business, like hurricanes and wildfires. With the COVID-19 Notification Best Practices overlapping with other critical events, Everbridge has adjusted its best practices for long-term messaging to minimize message fatigue for Contacts and increase message deliverability as organizations worldwide attempt to send alerts to their people.

Please note the differences in this document compared to historic severe weather resources, and that Best Practice recommendations for Priority events that require urgent response differ from these long-term messaging recommendations.

General Considerations

  • Consider Sharing Priority and Non-Priority Alerts Differently
    • Consider using limited Delivery Methods for Non-Priority messages, and publicize the change. This may include sending Non-Priority messages to Email, Everbridge Mobile App, and posting to a webpage, while Priority messages go to all of those methods and SMS and Phone Calls.
    • Post your announcement on a webpage before sending messages. This will give you the ability to insert a link to the message for recipients to visit, and allow you to share non-priority alerts in a separate space to limit non-priority messages.
    • Consider the use of URL shorteners to reduce the length of your SMS message.
    • Encourage Contacts to download the Everbridge Mobile App to receive messages on a Delivery Method Everbridge manages for effective delivery during times when first responders have priority over phone lines.
  • Pre-Plan Awareness Campaign
    • Post in newsletters, flyers, leaflets in utility bills or paychecks and tv displays at entrances, on your internet/intranet, and on Facebook, Twitter, and Instagram.
    • Mention the system and recent use cases at town halls and quarterly all hands meetings, and share the Everbridge Global SMS Codes that texts will come from for Contacts to save. U.S. public agencies sending messages to U.S. devices should note the updated SMS Sender ID of 88911 (not 89361).
    • List clear reminders about how the system will be branded to minimize phishing reports.
    • Outline how Contacts can update their information.
  • Include Other Departments/Leadership in Preparedness Efforts
    • IT/HelpDesk, HR/Public Relations/Corporate Comms/PIO, Security/GSOC, Business Assurance, Infrastructure/Telecom.
    • Ensure leadership/management at all locations are aware of impending test and expectations.

Everbridge Features to Review


Broadcast Timing and Duration

 Use a high Broadcast Duration - ideally, the highest setting of 24 hours.

  • This means the system will attempt to reach Contacts who have not yet confirmed through this time period and the amount of predefined Cycles. A high Broadcast Duration helps avoid “Confirmed Late” statuses and keeps recipients from receiving a “broadcast has ended” message if they confirm late via email.
  • Broadcast Duration is important for Broadcast Throttling and determines the amount of time a Public or Private Incident Zone is active, and should also be the same or longer than the Expires setting for IPAWS messages for US public agencies).

 Set a higher-than-usual Interval Between Delivery Methods for non-critical messages.

  • Setting the Interval Between Delivery Methods to three minutes is appropriate for an update that does not require immediate action to minimize disruption and message fatigue, while a zero or one minute Interval Between Delivery Methods should be used when immediate action is required - for example, during an evacuation order when only a few hours remain before landfall. This helps ensure Contacts trust your system and know you will only blast them at a rapid pace when there is an imminent threat.

 Adjust Multiple Cycles
  • Standard practice is to use one Cycle to attempt to reach Contacts with pertinent information, and avoid re-sending old information when new content should be sent. Contacts who do not see the message at first will still have a missed call, text, email etc.

SMS Options

    • Disabling Title in SMS Messages allows you to remove duplicate content from the Title of a message in the Body. Please note this applies across the organization, so existing templates should be updated to include relevant content from the title in the body and message senders should be instructed to ensure they include relevant content in the SMS body as well.
    • Be aware that if messages are over the limit for one SMS, the Include Short URL in SMS Confirmation may be ignored as only one URL will be used in the text to point to a longer message website.
    • Add a short name under the new SMS Message Prefix setting to automatically include your organization’s short name in every SMS to build credibility. If you had manually added short names to your templates in the past, remove those entries and ensure Users are not duplicating them in new messages.
    • SMS URL Duration determines how long the link created when an SMS message is longer than one text message is available to click and view online. For example, selecting 5 Days enables the message to be viewed an additional five days after your Broadcast Duration.
    • Header on SMS URL Web Page should reflect the same branding used for your Sender Name in emails and content used to brand your system with your Contacts.
    • Adding a Custom Badge to the web page used for SMS messages that take up more than one text allows Contacts who click on your Web Page Message to verify they are reading credible information from your organization. Add the same logo or banner used in emails, the Everbridge Member Portal, or organization-wide branding.

Caller ID

  • Ideally, have your IT organization provision a custom number with a voice recording (“You have reached XYZ Alerts, if you believe you received this message in error or have any questions…”)
  • Use a real phone number, not 123-456-7890 or 555-555-5555, as described in Caller ID Best Practices.
  • Avoid using the Ops center/phone bank to avoid inundation of callbacks on priority lines.

Sender Name

  • Should be a phrase or unique name for your alert system.
  • Using an email address may cause your message to be marked as spam (since email servers typically validate against noreply@everbridge.net).

Email Header & Footer

  • Use the same branding included in regular emails (logos, hyperlinks, confidentiality notices).

Is Confirmation turned on?

  • Turning Confirmation off means all Contacts receive all messages on all devices without an opportunity to confirm receipt. This can clog your outreach attempts and cause confusion.

Configure Broadcast Throttling

  • Setting limits to avoid overwhelming your local telephone provider’s limits for landline calls – use Everbridge’s Broadcast Throttling recommendations.

Whitelist Everbridge


  • Identify and resolve Contacts with no Delivery Methods.


Reminder: Existing Templates are not updated when Default Settings are changed. After changing Default Settings, edit your pre-configured Templates as well.

Notification Content

  • Ensure Use custom Email/Everbridge Mobile App message is enabled to create distinct messages per Delivery Method. Add the longer message in the Email box that appears and link to your announcement site in a way that uses branding and rich text formatting so your message is easy to comprehend, as outlined in FAQs for Utilizing Separate Email.
  • Voice recordings should be between 30 and 45 seconds, never more than one minute, and recorded by a human voice that recipients know whenever possible.
  • Ensure Use custom SMS message is enabled to create a custom SMS message and Web Page Message should the initial SMS go over 160 characters. Consider building a Web Page message with additional context once a Contact clicks the SMS URL.
  • Remember, messages over 160 GSM/70 non-GSM characters will create a separate Web Page with remaining information, so always build templates and train Users to include the event and a call to action for the recipient at the start of each message to provide relevant context to those who may not have access to the URL from their phone.
  • SMS messages should be kept under 160 characters to reduce the number of individual text messages Contacts receive at the same time, and start with a short sender name and call to action for the recipient. If Include Title in SMS Messages is enabled, remember the Subject line also counts toward 160 characters.
  • Consider using limited Delivery Methods for Non-Priority messages. This may include sending Non-Priority messages to Email, Everbridge Mobile App, and posting to a webpage, while Priority messages go to all of those methods and SMS and Phone Calls.  
  • Notification Templates are tied to an Event (“Hurricane X”) for easy reporting.  
  • Post to Social Media with Publishing Everbridge Notifications to Facebook & Twitter.


Do you have a Retraction template?
  • Something with basic “Please disregard the previous message that was sent in error. Details to follow” is handy in the event a message is accidentally sent (or wrong content included).

Member Portal

If using Everbridge Member Portal, make sure it is branded so Contacts trust the page.
  • Agencies that only want citizens who live in a certain area should ensure their Public portal has Use a Geo-Fence to control addresses enabled and their jurisdiction loaded to minimize confusion, and verify that Location field is Mandatory.
  • Agencies using SmartWeather and the Member Portal should review SMARTWeather Settings Best Practices.
