CloudMailin

The email API for developers.·cloudmailin.com

CloudMailin is a developer-focused email API that converts incoming email into HTTP POST webhooks so web applications can receive email without running a mail server. It also offers outbound transactional email sending via API and SMTP relay, along with deliverability tools such as DMARC monitoring and an SMTP troubleshooter. Emails can be parsed into JSON, Multipart, or RAW formats, and attachments can be offloaded directly to Amazon S3, Azure Storage, or Google Cloud Storage.
