We may cancel transactions involving multiple redemptions, particularly if it also exceeded Humble Bundle's limit of 2 per user.

Third, we will be honoring all the $25 codes that have already been redeemed (including the ones redeemed by existing paid users), with one possible exception.

This is particularly acute since it impacts cash flow over the next couple months when we expect to have higher expenses due to an ongoing datacenter expansion. While we really want to give both old and new users the same promotional opportunities, the fact that this is mainly being used (and in some cases abused) by existing users, combined with the fact that this was priced at $1 instead of $15 (as originally intended), creates a financial risk for us. However, actually most redemptions are existing paid users, which is counter to our original intent. This was the original intention, as we wanted to introduce ProtonMail to a new audience.

Second, we will be limiting this to just new paid users only. We did this promotion originally to support EFF (which is getting a portion of the proceeds), but given the current situation (where the average number of redemptions per user is 2.5), this has unfortunately become unsustainable for us, particularly since this can also be used in ProtonVPN, which has non-negligible bandwidth costs.Īs a result, we are making the following changes.įirst, this promotion will be limited to 1 per user (the limits placed by Humble Bundle are unfortunately not effective, as evidenced by the people who are using this promo 20+ times). Being placed in the $1 Humble Bundle tier also didn't help. Unfortunately this promotion is being heavily abused (some users have redeemed this over 20 times).
