ProtonMail's headline offer is up to 23% off plans, which gives the biggest savings for most shoppers. However, the best deal depends on what you're signing up for and how long you want to commit, since ProtonMail pricing varies significantly by subscription length and plan type.
For first time customers and small savers: If you're new to ProtonMail and want to test the service affordably, the free account option gets you started with encrypted email at zero cost. This is perfect if you just want to experience the platform or you don't need premium features yet.
For Plus plan shoppers: The 20% off a plus plan offer is worth comparing against the broader up to 23% deal. If you're specifically targeting the Plus tier, check which saves you more at checkout—some plan lengths might qualify for the higher percentage discount, while others might reach exactly 20% off.
For budget conscious annual subscribers: The monthly package for €6.25 is extremely competitive for longer term commitments, particularly if you're calculating your annual spend. Convert this to your local costs to compare against the percentage discounts on other plans.
For maximum savings on any plan: The up to 23% off plans offer should be your first stop. This applies across ProtonMail's full plan range and often beats individual tier offers, especially on longer subscription periods where the percentage saves compound.
When you reach checkout, only one offer applies, so compare the final price under each option with your specific plan choice and subscription length. The percentage discount that delivers the largest dollar saving is the one to take. Newsletter signup may offer additional benefits for future shopping, but the immediate discounts above should be your focus for this purchase.
