Question 1

What is UnionStack and how is it different from other WordPress hosts?

Accepted Answer

UnionStack is a European managed WordPress hosting platform that includes professional email (you@yourdomain.com) at no extra cost. Unlike WP Engine or Kinsta, every plan includes email infrastructure, SSL, backups, and monitoring. Pricing starts at €7/month with all features included — no add-ons or per-seat fees.

Question 2

How fast is UnionStack WordPress hosting?

Accepted Answer

UnionStack delivers 122ms median TTFB (Time to First Byte) and a 99.7/100 Lighthouse performance score, measured on a production WordPress site with 12 active plugins including WooCommerce and Elementor. Under load testing with 100 concurrent users and 14,570 requests, the error rate was 0.00%.

Question 3

Is UnionStack GDPR compliant?

Accepted Answer

Yes. All UnionStack infrastructure is hosted exclusively in European data centers (Hetzner, Germany). No data is transferred outside the EU. The infrastructure provider holds ISO 27001 certification and BSI C5 Type 2 audit attestation.

Question 4

Does UnionStack include email hosting?

Accepted Answer

Yes. Every UnionStack plan includes professional email powered by Stalwart Mail Server. You get addresses like you@yourdomain.com with full IMAP/SMTP support, compatible with Gmail, Outlook, Apple Mail, and Thunderbird. No separate email provider needed.

Question 5

How quickly can I deploy a WordPress site on UnionStack?

Accepted Answer

WordPress sites go live in under 5 minutes. The Kubernetes-based infrastructure automatically provisions databases, configures DNS, generates SSL certificates, and deploys your site. No manual server configuration needed.
