Posteo Doubles Storage

I have a Posteo email account. I was paying 1 Euro per month (or whatever that converts to in USD at the moment) for 2 GB of storage. Today, Posteo doubled the amount of storage on the 1 Euro plan from 2 GB to 4 GB. I do not think I was anywhere close to using 2 GB, but you will not catch me complaining about free upgrades. The only downside of Posteo is that it lacks custom domain support, but I cover that base with Simple Login. I will be looking at Thunderbird Pro when that is available, but for now the Posteo + Simple Login set-up works well.
