Question 1

How much does PostStack cost?

Accepted Answer

PostStack starts free with 3,000 emails per month. The Starter plan is €5/month for 10,000 emails, Pro is €15/month for 50,000, and Scale is €65/month for 100,000. Every paid tier is cheaper than the equivalent Resend, SendGrid, and Postmark tier — by up to 72% at low volumes and around 21% at higher volumes. The Starter tier is the cheapest paid tier on the European market.

Question 2

Is there a free tier?

Accepted Answer

Yes. The free plan includes 3,000 emails per month, one sending domain, five API keys, webhooks, and 14 days of log retention. No credit card is required to sign up.

Question 3

What happens if I exceed my plan limit?

Accepted Answer

Starter, Pro, and Scale plans bill overages at €0.65 per 1,000 emails. Free plan accounts are hard-capped at 3,000 emails per month. Usage is visible in real time in the dashboard so there are no surprise invoices.

Question 4

Can I cancel anytime?

Accepted Answer

Yes. Every plan is month-to-month with no long-term contract. Upgrade, downgrade, or cancel from the dashboard at any time, effective at the end of the current billing period.

Question 5

Where is my data stored?

Accepted Answer

PostStack runs on a Hetzner data centre in Helsinki, Finland. All email data is processed and stored inside the EU. PostStack is operated by a Danish company and is subject to EU data protection law, not the US CLOUD Act.
