What to Look for as a Startup
1. Affordable entry point
You need a tool that fits your current budget but can handle 10x growth. Look for transparent pricing that scales predictably.
2. Fast time-to-value
Every hour spent on email infrastructure is an hour not spent on your product. Choose tools with great documentation and quick setup.
3. Revenue tracking (for SaaS)
If you are selling subscriptions, understanding which emails drive revenue is crucial. Native billing integrations save you from building custom analytics.
4. Deliverability
Your emails must actually reach inboxes. Established providers with good reputations give you a head start.
