KMail
KDE
KMail is the email component of Kontact, the integrated personal information manager from KDE. Default settings rather compromise on features than security or privacy. End-to-end Encryption. Support for OpenPGP and S/MIME is built-in, and a setup and key generation wizard aids users in getting started with this. Transport encryption, SSL/TLS encrypted communication is of course supported, as are a number of authentication methods such as GSSAPI (Kerberos) or OAuth2. Strong isolation of HTML content. If HTML emails can’t be avoided, KMail ensures no external references can be hidden in there to leak information or compromise your privacy. Additionally KMail’s phising protections warns about suspicious links in such emails. Spam protection, so if your email server doesn’t take care of this already, KMail can integrate popular spam checkers such as SpamAssassin or Bogofilter locally. -

Helpwise
Helpwise
Shared Inbox for your Team Email, SMS & WhatsApp accounts. Sharing email account login among team members is not scalable. Helpwise is an easy to use shared inbox for your team email accounts like help@, sales@, jobs@ etc. As business grows, it becomes a struggle to manage customer, sales or internal emails (billing, hiring) across the company. And, then we make a blunder by sharing email logins among team members. We understand the chaos that it creates because we have been through the same pain during our previous gigs & businesses. So, this is exactly why we built Helpwise - the shared inbox that really works! We all love Gmail, Outlook & other awesome email clients. So, we have made sure that Helpwise feels as easy as these common email services. Basically, you won't miss them here. Every team member will get own separate login to access same email address. So, no more password sharing. Better security with higher productivity! -
