Yes, and no card is required. You get 1 domain, 10 aliases, 50 emails a day, 3-day retention and the full webmail inbox, for as long as you want it.
Do you charge per email?
+
No. Every plan is a fixed monthly price with a generous daily ceiling, so a busy week never produces a surprise invoice.
What happens if I hit my daily limit?
+
Messages beyond the daily ceiling are rejected at SMTP time, which means the sender gets a bounce rather than silently losing mail. Upgrading raises the ceiling immediately.
Can I cancel or downgrade?
+
Any time, from the billing portal. There is no contract and no lock-in — your MX records are yours to point elsewhere.
Where is the data stored?
+
Servers in Germany, object storage in Amsterdam. Everything stays in the EU.
