Frequently Asked Questions

Common questions about Frumbik SMTP

Absolutely. Frumbik SMTP works with any hosting that supports PHP 7.4+ and allows outbound SMTP or HTTP connections. This includes Bluehost, SiteGround, GoDaddy, Namecheap, OVH, Zenbox, and virtually all shared hosting providers.

In most cases, yes. WordPress's default mail() function sends unauthenticated emails that spam filters flag immediately. Frumbik SMTP routes emails through properly authenticated connections (SMTP with TLS or native APIs), which dramatically improves inbox delivery rates.

Yes — every plugin. Frumbik SMTP hooks into WordPress's wp_mail() function, which means all emails from WordPress core, WooCommerce, contact forms, membership plugins, LMS plugins, and any other plugin are automatically routed through your configured provider.

Not with Frumbik SMTP. Configure a backup connection and enable automatic failover. If your primary provider fails, emails seamlessly route to the backup. You can also enable the email queue, which stores emails and retries them automatically when the provider recovers.

Yes. All sensitive credentials are encrypted using AES-256-CBC with HMAC authentication before storage. The encryption key is derived from your WordPress security keys, or you can define a dedicated key in wp-config.php for even stronger protection. Credentials are never stored in plaintext.

Yes, both are supported: * Gmail — Connect via the Gmail API with OAuth 2.0 (no app password needed) or via SMTP * Microsoft 365 / Outlook — Connect via the Microsoft Graph API with OAuth 2.0 or via SMTP * OAuth tokens are securely encrypted and automatically refreshed

Yes. All features listed above are included in the free version.

Yes! The setup wizard can automatically detect and import settings from WP Mail SMTP, Post SMTP, Fluent SMTP, and Easy WP SMTP. Your existing configuration is migrated in one click.

Yes. The email queue is powered by WP-Cron with configurable batch sizes and intervals. For high-volume sites, we recommend setting up a real server-side cron job for more reliable timing.

Yes. Frumbik SMTP fully supports Multisite with network-wide or per-site configuration options and a dedicated network admin panel.
