Web Push Notifications: Send notifications to users who have opted-in to receive notifications from your website or web application.2. Email Newsletters: Send newsletters to subscribers who have opted-in to receive emails from you.3. Social Media: Share updates and notifications on social media platforms to reach your followers.4. RSS Feeds: Publish updates and notifications through RSS feeds for users who have subscribed to your feed.5. API Integrations: Integrate with other services and applications to reach their users (e.g., Twitter API, Facebook API).6. Advertising: Use targeted online advertising to reach a large audience.7. Content Syndication: Share your content on other websites and platforms to reach a broader audience.8. Partnerships and Collaborations: Partner with other organizations or influencers to reach their audience.Keep in mind that each method has its own limitations, requirements, and best practices. You should always respect users' privacy and follow applicable laws and regulations when sending notifications.
