It's easy to use as you can create multiple profiles with different themes that match your branding needs! The support team was super helpful in helping me find what I needed from them too quickly (as opposed to taking forever). No issues so far but they have an amazing customer service department here at MailSpring which makes up it all by itself!! Definitely recommend using their platform if possible because of how simple everything works together! Easy setup process between our email marketing platforms - Zapier integration- and other tools we used like Hubspot or Marketo/Pardot etc.-.
