Error message

Please verify your email settings

What it means

EmailError, thrown by handleResponse when errors[0].type === 'EmailError'. It signals that an email-sending operation failed because of misconfigured or unavailable mail transport (Mailgun, SMTP, etc.). The specific transport error detail is in error.data.

Solutions

  1. Open Ghost Admin → Settings → Labs / config and verify the mail transport settings (Mailgun key+domain or SMTP host/port/user/pass).
  2. Send a test email from the admin to confirm the transport works end-to-end.
  3. Inspect error.data for the underlying transport message (auth failure, connection refused, etc.) and fix that specific cause.
Defensive patterns

Strategy: type-guard

Type guard

import {EmailError} from '@tryghost/admin-x-framework/utils/errors';
function isEmailError(e: unknown): e is EmailError {
    return e instanceof EmailError;
}

Try / catch

import {EmailError} from '@tryghost/admin-x-framework/utils/errors';
try {
    await api.users.invite({email});
} catch (e) {
    if (e instanceof EmailError) {
        notify('Email sending failed. Check your mail settings in Labs.');
        // e.data?.errors?.[0]?.message has the transport-specific error
    } else throw e;
}

Prevention

When it happens

Trigger: Triggering a send — staff invite emails, member signup confirmation, newsletter publishing, magic-link login — while the mail service is misconfigured, has bad credentials, or is unreachable. Ghost returns {errors:[{type:'EmailError', ...}]} with the transport's error.

Common situations: Mailgun API key/region mismatch; SMTP host/port/encryption wrong; email from-address not verified; mail provider rate-limit or outage; DNS (SPF/DKIM) issues surfacing as transport errors.
