What are the most important features from email marketing software you look for?

from user pov one click unsubscribe should mean one click unsubscribe
not 'it will take 30 days'
or 'manage your subscriptions'
or the hellish 'login to manage your preferences'
it should be ONE click to unsubsctibe or at worst click unsubscribe and then click a confirm button
from a users pov

lol couldn't agree more - I hate those '30 days unsub' nonsense. Nha, these days if you don't add a 1-click unsub header your email wouldn't even get delivered so we have that.

Good automation
Personalization options
Solid analytics
Works well with my other tools
Responsive customer support
