Which email API services are easiest to set up for password resets and onboarding emails?

For password resets and onboarding emails, the easiest email API services to set up are usually the ones with:

• simple SMTP or REST API integration
• good deliverability by default
• clear templates / transactional email support
• easy DNS setup for sending domains

Easiest options
