Frequently Asked Questions
Common questions about Super Duper SMTP Mail Bridge
Any standard SMTP server works: Gmail, Outlook/Office 365, Mailgun, SendGrid, Amazon SES, Postmark, your own mail server, your hosting provider's SMTP – if it speaks SMTP, this plugin connects to it.
Yes. SMTP passwords are encrypted with AES-256-CBC (using OpenSSL) before storage. The encryption key is derived from your WordPress AUTH_KEY salt. Most other SMTP plugins store passwords in plain text or simple base64 encoding.
If you have configured a backup SMTP server, the plugin automatically retries the email through the backup. Both the primary failure and the backup attempt are logged separately, so you have full visibility.
Rate limiting caps the number of emails your site can send per minute, hour, or day. This protects you if a contact form gets spammed, a plugin sends mass notifications, or your site is compromised. Emails exceeding the limit are blocked and logged.
All plugin data is completely removed: options, transients, and the custom log database table. No traces left behind.
Yes. All WooCommerce transactional emails (order confirmations, shipping notifications, password resets) are sent through your configured SMTP server.
Rate limiting, domain whitelisting/blacklisting, BCC monitoring with GDPR compliance, sender domain validation, and AES-256 password encryption are features no other free SMTP plugin offers. If you want maximum control over your email delivery without paying for a Pro license, this is your plugin.
Under GDPR, you may need to prove that a specific email (e.g. a consent confirmation, data deletion notice, or privacy policy update) was actually sent to a user. The email log provides a timestamped record with full content, and the BCC copy gives you an independent second proof stored in a separate mailbox. Together, this creates a verifiable audit trail that can hold up in legal disputes – something no other free SMTP plugin provides out of the box.
