Mailgun
Mailgun (by Sinch) is an email API platform with a strong focus on deliverability and inbound email processing. The inbound parsing feature is a differentiator — it can receive emails, parse them, and forward structured data to a webhook.
For AI agents that need to process incoming emails (parsing customer requests, extracting data from email threads), Mailgun's inbound routing is a useful capability that most competitors don't offer natively.
