What the free plan gives you

Free plan with 1GB storage.

When you would pay

The free plan is bounded (free plan with 1GB storage), so treat it as a genuine trial of the product rather than a permanent home. It is enough to decide whether Proton Mail fits before any money changes hands.

We list Proton Mail because the free plan was checked against its own pricing page, not because a vendor asked. If it has changed, tell us and we will re-check it.

When to upgrade to a paid plan
