Delivery Mechanisms and Reliability
Email notifications travel through traditional SMTP infrastructure, making them subject to email server performance, spam filtering, and potential delivery delays. Push notifications leverage mobile platform services like Apple Push Notification Service and Firebase Cloud Messaging, providing more direct delivery with confirmation capabilities. However, push notifications require users to have the Now Mobile app installed and maintained, while email works with any email client. Both methods can fail due to network issues, but push notifications generally provide better delivery visibility and faster receipt confirmation.
Templating and Content Customization
Email notifications offer superior templating capabilities through ServiceNow's email template system, supporting HTML formatting, embedded images, and comprehensive record details. Administrators can create sophisticated notification layouts with branding, detailed context, and actionable links. Push notifications are limited to short text messages with basic formatting, making them suitable for alerts but inadequate for detailed information sharing. Email templates can be version-controlled and tested extensively, while push notification content options are constrained by mobile platform limitations and character count restrictions.
User Preference Management
Email notification preferences in ServiceNow provide granular control over frequency, timing, and content through the notification preference system. Users can configure digest schedules, opt-out of specific notification types, and set up sophisticated filtering rules. Push notification preferences are more basic, typically offering simple on/off toggles for different notification categories. Email systems allow users to create rules, folders, and automated responses, while push notifications rely primarily on device-level settings for management. The preference complexity makes email more suitable for power users who want detailed control.
On-Call and Critical Incident Response
Push notifications excel in critical incident scenarios by providing immediate, attention-grabbing alerts that bypass email inbox clutter. They support escalation workflows where multiple notification attempts can be made with increasing urgency indicators. Email notifications may be delayed or missed during critical incidents, especially if users don't actively monitor their inbox. However, email provides better incident documentation and can include detailed troubleshooting information that mobile notifications cannot accommodate. Many organizations use push for initial alerting and email for detailed incident context and documentation.
Digest and Batch Processing Strategies
Email notifications support sophisticated digest functionality, allowing multiple notifications to be batched and sent at scheduled intervals to reduce inbox overload. ServiceNow's digest system can group related notifications and provide summary information with drill-down capabilities. Push notifications lack native digest functionality and are typically sent individually, which can overwhelm users during high-activity periods. Email digests can be formatted with rich content and organizational structures, while push notifications require careful frequency management to avoid user fatigue and notification dismissal.
Which should you choose?
Choose Email Notifications when
Choose email notifications when you need rich content delivery, detailed record information, and comprehensive user preference control. Email is ideal for non-urgent communications, audit trails, and scenarios where users need to reference notification content later. Organizations with complex notification requirements, custom templating needs, or users who prefer managing communications through email systems should prioritize email notifications. Email works well for batch processing scenarios and when integration with external email management tools is required.
Choose Push Notifications (Mobile) when
Choose push notifications for time-critical alerts, on-call scenarios, and situations requiring immediate user attention. Push notifications are essential for major incident management, system outages, and emergency communications where delays could impact business operations. Organizations with mobile-first workforces, field service teams, or users who are frequently away from email should implement push notifications. They're also preferable when delivery confirmation is crucial and when you need to ensure notifications aren't lost in email inbox clutter.
Verdict
The optimal ServiceNow notification strategy typically combines both email and push notifications rather than choosing one exclusively. Use push notifications for urgent, time-sensitive alerts that require immediate attention, while leveraging email notifications for detailed information sharing, documentation, and non-critical communications. Most organizations benefit from configuring push notifications for high-priority incidents and on-call scenarios, with email handling routine updates, approvals, and informational messages. The choice depends on your organization's operational requirements, user preferences, and the criticality of different notification types.
Frequently asked questions
Can users receive both email and push notifications for the same event?
Yes, ServiceNow allows administrators to configure multiple notification channels for the same event through notification schemes and business rules. Users can receive both email and push notifications simultaneously, though this may lead to notification fatigue. It's recommended to use different channels for different priority levels rather than duplicating all notifications across both channels.
How do notification preferences work differently between email and push notifications?
Email notification preferences are managed through ServiceNow's comprehensive preference system with granular controls for timing, frequency, and content. Push notification preferences are simpler, typically offering basic enable/disable options for notification categories. Users have more control over email notifications, while push notifications rely heavily on device-level settings for fine-tuning.
What happens if the Now Mobile app is not installed or updated?
If the Now Mobile app is not installed or is outdated, push notifications will fail to deliver, and users won't receive critical alerts. This creates a dependency risk that doesn't exist with email notifications. Organizations should have fallback mechanisms and policies ensuring users maintain updated mobile apps, or use email as a backup channel for critical notifications.
Can push notifications include clickable links or actions like email notifications?
Push notifications support basic actions and can deep-link into the Now Mobile app to specific records or forms. However, they cannot include the rich HTML links, embedded content, or complex actions available in email notifications. Email notifications provide more sophisticated interaction capabilities, including approval workflows and direct links to web interfaces.
How should organizations handle notification fatigue with both channels?
Organizations should implement notification governance by categorizing communications by urgency and using appropriate channels for each type. Reserve push notifications for truly urgent matters, use email for informational content, and implement digest strategies to batch non-critical notifications. Regular review of notification volumes and user feedback helps optimize the notification strategy and prevent user overwhelm.
Are there any compliance or security differences between the two notification methods?
Email notifications may be subject to email retention policies and can be more easily archived and audited through standard email systems. Push notifications have shorter retention periods and limited audit trails within mobile platforms. For compliance-heavy industries, email notifications may provide better documentation and audit capabilities, while push notifications offer more secure, direct delivery that bypasses email infrastructure vulnerabilities.
