Pros
Pro Not just an e-mail client
Seamonkey is more than just an e-mail client as it is a full featured web browser as well. This makes for a good app to use for those that dislike having many different apps on their devices as it is a bit like an all in one solution.
Pro Auto imports setting from Thunderbird
For those that would be making the switch from the Thunderbird e-mail client setup is quite easy with Seamonkey as it auto imports all previous Thunderbird settings.
Pro Simple and modern UI/UX design
Cons
Con Permanent CPU usage
Seamonkey permanently uses CPU (quite a few percents on a Intel i7). On a laptop this causes the fan to run (which make noise) and the battery to lasts less time.
Con Dead product
No release in well over a year, no support, and a permanent "never to be repeated" offer. This product is now looking like a con itself.
Con Not free
You have to subscribe to a paid plan to use it.
Con Cannot unsubscribe or cancel service
Cancellation requests go unanswered but the yearly invoices continue to arrive and credit card is charged.
