Asked Questions
Clear answers on how Xem works, how your data stays secure, and how to get started in minutes.
Clear answers on how Xem works, how your data stays secure, and how to get started in minutes.
Is Xem really free?
Yes. The core software is open source and free forever. Self-host at no cost beyond your infrastructure expenses. Our cloud-hosted version also has a free tier with 1,000 emails/month.
How is Xem different from SendGrid, Mailchimp, or Klaviyo?
Xem is open source and designed to prevent vendor lock-in. You control your data, your infrastructure, and your email providers. You can self-host at zero cost. Other platforms are proprietary SaaS with per-email or per-contact fees.
Can I really switch SMTP providers without changing my code?
Yes. That's Xem's core feature. Switch providers from the dashboard instantly. Your API calls remain unchanged. Perfect for failover, load balancing, or cost optimization.
Do I need technical skills to use Xem?
Our dashboard works for non-technical users. But Posthoot is built for developers—the API, self-hosting, and customization options require some technical comfort. We have excellent documentation.
What about compliance—GDPR, CCPA, HIPAA?
Self-hosting means you control data residency and handling. Posthoot supports all necessary compliance features: unsubscribe management, audit logging, data deletion, and encryption.
Can I integrate Xem with my existing tools?
Yes. Our REST API works with any platform that makes HTTP requests. Webhooks enable real-time data flows. Custom integrations are possible via code.
Is there a limit to how many emails I can send?
No. Free tier has monthly email limits, but Pro and self-hosted deployments are unlimited. Scale as much as your SMTP providers allow.
How hard is it to self-host Xem?
Very easy. Clone the GitHub repo. Run docker-compose up. Configure your SMTP providers. You're live in minutes. We have detailed documentation for every deployment option.
Is there a free trial?
Yes. You can use all core features for free before choosing a plan.
