Used For

• +**Your website events aren't reaching your CRM, so sales has no idea what prospects actually did** → One setup routes user actions to Salesforce, email tools, and analytics automatically
• +**You're manually copying user data between 5 different tools for 20 hours a week** → Set up once, data flows everywhere automatically, get your weekends back
• +Real-time audience building - create "big spenders" segments that update automatically across all your marketing tools
• +**Your BeautifulSoup scripts break when sites update, losing 20% of tracking data** → Handles JavaScript rendering and schema changes without your intervention
• +Server-side tracking bypasses ad blockers and privacy tools that kill your analytics

Best For

• >Your team wastes 15+ hours a week manually exporting data between analytics tools
• >You're duct-taping data from website, app, and email tools - nothing talks to each other
• >Your current custom scripts break every weekend at 3am and you're tired of fixing them

Not For

• -Solo developers or startups under 10 people — requires dev setup and you'll hit the free tier limits in days
• -Anyone wanting simple plug-and-play — this needs actual configuration time and ongoing schema maintenance
• -Budget-conscious teams — usage-based pricing means traffic spikes can double your bill overnight

Pairs With

• *Google Analytics (where basic website metrics go, though Segment makes this redundant)
• *Amplitude (for product analytics since GA4 is terrible for app tracking)
• *Salesforce (where your sales team actually needs to see what prospects did on your website)
• *Snowflake (your data warehouse where everything eventually gets stored for real analysis)
• *Mailchimp (for email campaigns triggered by user behavior Segment tracks)
• *Mixpanel (another analytics tool because you'll probably try 3 before finding one you like)
• *Slack (where you get alerts about data pipeline failures at 2am)

The Catch

• !The "1 million tracked users" free tier sounds generous but fills up in days if your users trigger frequent events
• !Rate limits will throttle your high-traffic periods — users report losing 20% of events during busy periods like Black Friday
• !You'll need someone to babysit event schemas or they'll drift and break integrations over time

Bottom Line

Saves you from manually piping data between tools, but you'll hit usage limits faster than expected and overage fees hurt.
