Common Questions

Frequently Asked Questions About Pricing

Can I connect both Google Workspace and custom SMTP mailboxes?

Yes. All plans allow you to mix and match Google Workspace accounts (connected via OAuth 2.0 PKCE) and custom SMTP/IMAP servers (Microsoft 365, Amazon SES, or private Postfix/Exim instances).

What happens if my team exceeds our monthly send limit?

Outbound messages are held safely in the background dispatch queue rather than dropped or bounced. You can upgrade your tier instantly from the console or purchase volume add-on packs.

Is there a setup fee or long-term contract?

No. All plans operate on a flexible monthly subscription with no setup fees or lock-in contracts. You may cancel, upgrade, or downgrade your package at any time.

Do you provide self-hosted on-premise deployments?

Yes. For enterprises with strict data residency and security compliance requirements, we provide self-hosted CodeIgniter 4 license packages deployed inside your private cloud environment.
