Frequently Asked Questions
Common questions about SendForce Mail SMTP Relay — Free WP SMTP & Email API Plugin for Amazon SES, SendGrid, Mailgun, Brevo, Postmark, Zoho ZeptoMail & Gmail
Yes. You need access to an SMTP server or a transactional email provider account. Most providers (Gmail, Outlook, etc.) offer SMTP access. Transactional services like SendGrid, Mailgun, or Amazon SES offer both SMTP and HTTP API access.
Yes. All credentials are encrypted using AES-256-CBC encryption with a key derived from your WordPress security salts before being stored in the database.
When enabled, emails are stored in a database queue instead of being sent immediately. A WP-Cron job processes the queue every 5 minutes, sending emails in batches. Failed emails are retried with exponential backoff (5 min → 15 min → 45 min).
Yes. SendForce Mail Relay hooks into WordPress's phpmailer_init action (SMTP mode) or pre_wp_mail filter (API mode). Since every plugin — including WooCommerce, contact form plugins, and membership plugins — sends email via WordPress's wp_mail() function, SendForce Mail Relay will handle 100% of outgoing emails.
You should only use one SMTP plugin at a time. Please deactivate any other SMTP or email plugins (FluentSMTP, WP Mail SMTP, etc.) before activating SendForce Mail Relay.
By default, SendForce Mail Relay logs: recipient email, subject, headers, status (sent/failed), error message if any, and timestamp. Email body logging is optional and can be disabled in Settings > Queue & Logging for privacy compliance.
All plugin data (database tables, settings, and scheduled events) is completely removed when you delete the plugin through the WordPress admin.
No. SendForce Mail Relay does not collect any data, make any analytics calls, or communicate with any external server except when sending emails through your configured provider.
