Frequently Asked Questions

Common questions about ByteCoreStack - SMTP & Health Monitor

SMTP (Simple Mail Transfer Protocol) is the standard, authenticated way to send email. WordPress's default mail() function has no authentication, which is why its messages are frequently marked as spam or rejected outright by Gmail, Outlook, and Yahoo. Routing through a real SMTP connection — your host, Gmail, Microsoft 365, or a transactional provider — fixes that.

The most common causes are: your host has disabled the PHP mail() function, your SMTP credentials are wrong or expired (Gmail/Microsoft App Passwords expire or get revoked), the wrong port/encryption combination is selected, or your host blocks outbound SMTP ports entirely. Use Send Test Email in this plugin — it classifies the failure (authentication, rejection, or system error) so you know which of these it is instead of guessing.

Yes. You must use a Gmail App Password — Google no longer allows regular account passwords for third-party SMTP clients. Enable 2-Step Verification on your Google account, then generate an App Password under Security → App Passwords.

Yes. Use your Microsoft 365 account password or an app password. Set the host to smtp.office365.com, port 587, encryption TLS. See Microsoft's official SMTP relay setup guide if you need app-specific credentials or hit a sending limit.

Yes. Google Workspace also supports a dedicated SMTP relay service for higher sending limits than a personal Gmail App Password allows — useful if you're sending a high volume of transactional email.

Yes — any provider that offers SMTP relay credentials works, since this plugin speaks standard SMTP rather than a provider-specific API. Grab your SMTP host/port/username/password from each provider's own setup docs: * SendGrid SMTP setup * Mailgun SMTP setup * Amazon SES SMTP setup * Brevo SMTP relay * Zoho Mail help center

Yes. WooCommerce order emails, and any other plugin that sends email through wp_mail(), automatically use the SMTP settings configured here — no separate configuration needed on the WooCommerce side.

Yes. Any plugin that uses the standard WordPress wp_mail() function routes through your configured SMTP settings automatically.

No. This plugin is built for transactional email — order confirmations, password resets, contact form notifications, account emails. For bulk marketing sends, use a dedicated service such as Mailchimp, Klaviyo, or Brevo's marketing product.

Yes, and there's nothing destructive about it. Deactivate your current SMTP plugin (or leave it active and just enable this plugin's "Enable SMTP" toggle — whichever hooks phpmailer_init last wins), enter your SMTP credentials here, and send a test email to confirm. Nothing about switching SMTP plugins affects your site's actual email content or past history.
