Casdoor sends sign-up verification codes, password reset links and magic links through an Email provider. It has native API types for Resend, SendGrid and Azure Communication Services (ACS) Email, a Default SMTP type that works with any SMTP relay (your own server, Google Workspace, Microsoft 365, Brevo, Amazon SES), and a Custom HTTP Email type for any other HTTP API. If you want a free tier and a short setup, start with Resend or Brevo. If you already run on AWS or Azure, SES or ACS keeps billing in one place. Whichever you pick, the deliverability work is the same: a sender domain with SPF and DKIM that align with the From address.

MailHog and Mailpit are both fake SMTP servers for development: they accept every message, keep it, and show it in a web UI instead of delivering it. Both use the same default ports, SMTP on 1025 and the web UI and API on 8025, so the SMTP address is smtp://127.0.0.1:1025 and the inbox is at http://127.0.0.1:8025 for either one. The difference is maintenance: MailHog's last release, v1.0.1, came out in August 2020, while Mailpit released v1.33.0 on October 31, 2026. For a new project, use Mailpit. Casdoor sends to both through a plain SMTP provider, so you can test sign-up codes, password reset emails and magic links without a real mail account.
