When you send an email, you can press the More drop down in the compose window and select 'Request Read Receipt'. You can click on the group in the composer to get a pop-up where you can uncheck any recipients and check their encryption and signature status.Īnother feature in this release is read receipts. Once configured, begin writing a new email and type in the group name in the To: field. To create a group, head to Contacts and select “Add contact group”. If you have a certain group of contacts who you regularly need to email setting up a group saves you time. With contact groups, you can add up to 100 email addresses to a group and manage them from the compose window. There's also a storage limit notification to let you know if you’re about to run out of space. Among them, contact groups - which let you easily send out bulk emails -, read receipts - which, if your recipient confirms, will let you know that they checked the email -, and typo warnings in the address bar. ProtonMail has announced the release of version 3.15, which brings several new features.
