You can select a color theme out of 6 templates. It was a complete revamp which hadn't changed since the start seven years ago when they first launched. Though, recently they have redesigned their whole UI.

Previously Proton Mail used to have the only layout option. Plus, this address does not count towards the total limit of addresses you can create with a single account. For example, if your email address is, you can swap out and instead use pm.me domain All users can receive pm.me emails, but replying from pm.me addresses is only reserved for premium users. If you find the domain daunting, why not make it shorter? You can receive emails to your associated inbox by keeping your mailbox name and switching out the domain name. Also, if you no longer need a label, you can delete it without second thoughts – it will not delete any emails. Should you decide to remove a label from email, it will not change their folder. The best part is that you can add emails to labels, and it will not interfere with your folders categorization. To increase their service's flexibility, Proton Mail has custom labels that you can add separately from folders. Many service providers have folder options to group emails, but it may not be enough. If you value productivity, organizing your mailbox can be tedious if the service developers didn't care for user experience. Visit Proton Mail to read more about the features
