“Aerc is a TUI email client that has been ‘babied’ in its ~4 years of existence compared to veterans like Pine and Mutt. Initially skeptical due to a lack of features, a recent revisit pleasantly surprised me. Aerc’s inbuilt help feature is handy and the account configuration is straightforward with flexible folder mapping options to maintain a consistent structure across different servers. The email viewing experience is average due to HTML email issues, but aerc offers solutions like HTML parsing and custom filters. Email authoring in vim is a joy, but the address book functionality may need improvement. PGP support is seamless, and general features like signatures and attachment reminders enhance the user experience. Overall, aerc has proven to be a polished and enjoyable email client worth sticking with.”
