Gmail vs Outlook

Pick Gmail if your team runs on Google Workspace and you need tight calendar-email coordination through AI. The 23 tools cover send, search, label management, and draft handling—enough for most automation without drowning in options. OAuth2 setup is standard Google flow. Pick Outlook if you're in a Microsoft 365 shop or need deeper mail operations. The 43 tools include folder hierarchies, rules management, and more granular attachment handling that enterprise IT teams actually use. For pure email automation, Gmail's simpler surface makes onboarding faster. Outlook's extra tools matter if you're routing complex approval workflows or syncing with SharePoint. Switching between them after you've built AI workflows means re-mapping every send and search call—budget three to five days if you have more than a handful of automations wired in. Neither locks you into proprietary formats, but your prompt library won't port cleanly.
