Bird Email
The email API for developers who ship the rest of the message too.·sparkpost.com
Bird Email (built on the infrastructure formerly known as SparkPost) is a developer-focused email API for sending transactional and marketing email on the same network that also carries SMS, voice, and WhatsApp. It handles authentication (DKIM/SPF/DMARC), dedicated IP warm-up, suppression management, templated and batch sending, deliverability analytics, and inbound email parsing, all through one API with signed webhooks. SDKs are available for Node.js, Python, Go, and PHP, alongside a CLI and REST access.
