Con Poor customer service
Developers changed their business model to the subscription based completely unanounced. Consequently, customers who hadn't logged in for a while could no longer access their account and remove their data. HQ rarely answer emails from users who have issues.

Sometimes it stops working as it should be.
Con Inadequate editing tools
No font selection, size or color. Can't paste an image to send. No table builder, etc.
Con Muy lento al procesar varias cuentas de mail
Cuando se programan varias cuentas de mail se vuelve insufriblemente lento, al punto de tildarse el programa y tener que reiniciarlo. El sistema donde está instalado es bastante potente (Intel i5, MB Asus, 16 GB Ram) y aún así va muy lento. No ocurre lo mismo cuando está configurado con una sola cuenta de mail.
Con Poor integration with Yahoo Mail
Integrations with a Yahoo Mail account doesn't always work well in eM Client.
