How to Choose a Email Tool

Key questions to ask
- ? Open source vs managed — who handles security patches and uptime?
- ? Pricing model — does it stay affordable as you scale?
- ? Learning curve — does your team already know this technology?
- ? Community and ecosystem — are there answers on Stack Overflow and maintained libraries?
