Cons

No encryption available.

There is no optional horizontal layout for those that want to be able to view their emails headers across the full screen.

It may look out of place in any other desktop environment.
Con No incoming message rules
Con Too basic
Very Basic, cannot format date, cannot create new folders - What!!
Con Not seen as a secure app by Gmail
Con No native Exchange support
Whilst possible if your Exchange server and account are using Davmail as a proxy, at the moment you can't natively add an Exchange account.
Con Development is pretty dead
No real development since October 2017.
This should be changed from a "Con" to a "Pro" as the Librem 5 smartphone has Geary as the default email application. There is ongoing development happening as can be seen at https://gitlab.gnome.org/GNOME/geary/commits/mainline
Con No Pop3 support
Con Bad HTML rendering
The HTML rendering of email messages is not full fledged. Some messages can appear a bit off compared to their appearance on browsers
Con No images in HTML signatures
Whilst it is possible now to add a HTML or plain text signature per account, there is no support for per images in the signatures. This is a must for when an employer imposes a set signature with images.
Con Its bloated
IT requires many GNOME dependencies or it will be unusable on the most non other X11-desktops
Con No proxy support
Seems like it can't retrieve email from behind proxy.
Con Blocks and freezes all the time
Con Saves passwords in plain format
Con Too much bloat
some people dont like the simple design of slypheed so they forked it and created claws mail but it has become so bloated since itsbeginnings.
Con Saves emails in uncompressed format
This takes more space on the HDD.
Con Interface looks old and setup is not easy
The icons as well as the rest of the interface look like an application from the early 90's, with this there is also no easy setup options built in like the more modern e-mail clients.
