Research Question
The user sought a cost-effective platform to poll Gmail every 10 minutes (~4,300 executions/month) for new or unread emails and notify a Slack channel.
Key Findings
- Task requires ~4 steps per workflow: Gmail trigger, check unread/new emails, Slack notification (1 workflow).
- Platforms compared for cloud deployment: IFTTT Pro ($4.99/month, $35.88/year), Windmill Team ($10/month, $120/year), FlowFuse Starter ($20/month, $220/year), Make Core ($28/month, $252/year), n8n Pro ($60/month, $600/year), Pipedream Connect ($150/month, $1,188/year), Relay.app Professional ($378/month, $2,268/year), Zapier Professional ($283.5/month for 20,000 tasks, $2,268/year).
- Zapier Free tier unsuitable: limited to 100 tasks/month, 2-step Zaps only, no custom polling (defaults to 15 minutes via Schedule by Zapier); user's volume (~10k-17k tasks at 80% billable ratio) exceeds by 100x+.
- Pricing verified as of 2026-04-20; automation saves ~$15,000/year vs. manual processing.
- All platforms lack free tier fit; IFTTT best for basic notifications, beginner difficulty (0.5-hour setup).
Recommendation
IFTTT Pro is the most cost-effective at $4.99/month ($35.88/year) for this simple polling and notification workflow, as a beginner-friendly option for basic notifications. Consider Windmill Team ($10/month) or FlowFuse Starter ($20/month) for developer-oriented self-hostable alternatives. Avoid Zapier Free due to task limits, step restrictions, and polling constraints; use Professional tier if needed (~$284/month). Assumes 1 item per execution and cloud deployment.
