Email

Email is optional. It powers:

• sign-up confirmation and welcome emails,
• invitations for new customers and collaborators,
• password reset links and security notices,
• receipts, payment reminders and other billing emails,
• the email notification channel.

Without email, invitations return a link you can pass on yourself and password resets are done by an administrator.

Configure

Settings → Panel → Email:

Field	Meaning
Host, port	Your SMTP server. Port 587 with STARTTLS is typical; 465 with TLS.
Security	none, starttls or tls
Username, password	Optional. The password is stored encrypted.
From	admin@example.com or Fledge <admin@example.com>

Use Send test email to verify. The same values can seed the form from .env (SMTP_HOST, SMTP_PORT, SMTP_SECURITY, SMTP_USER, SMTP_PASSWORD, SMTP_FROM); once saved in the panel, the database wins.

Templates, retries and the delivery log

Every email is a template you can edit. Mail goes out immediately; if the mail server is down it is kept and retried with growing pauses (a minute up to six hours, 8 attempts by default). The delivery log shows status, attempts and the last error. Also settable here: a Reply-To address, a copy address for receipts and billing alerts, the messages per minute, the attempts and how long the log is kept.

Behaviour

• Reset links work once and expire after an hour; invitation links work once and expire after 7 days.
• Asking for a reset always answers "ok", whether or not the address exists, so addresses cannot be probed.
• An administrator who resets their password still needs their authenticator.
• A password reset signs the account out everywhere and revokes its API tokens.
