Your Sarbacane account has a single support level (Essential, Premium or Exclusive), which applies to all your licenses and all your users. To upgrade to a higher level, contact your account manager: you can change levels at any time, and the difference will be charged pro rata until your subscription renewal.
Essential: access to customer support, chat, the help center, webinars, tutorials, white papers and the blog.
Premium: everything included in Essential, plus priority handling of your calls and requests, and advanced features (for example, predictive sending in Sarbacane Campaigns or the chatbot in Sarbacane Chat).
Exclusive: everything included in Premium, plus a dedicated coach, with a monthly meeting to review your statistics..
The full list of features for each level can be found in the article Sarbacane Essential, Premium or Exclusive: what are the differences?.
The support level is set for the account owner, not by user or application:
all your licenses have the same level: if you choose Premium for your first license, the licenses you add will also be Premium;
all users invited to the account benefit from the same level;
you cannot subscribe to applications with different levels.
Any change of level must be made through your account manager.
Moving to a higher level (from Essential to Premium, or from Premium to Exclusive): this is possible at any time. The new level applies to all licenses on the account, and the difference is billed on a prorated basis until your subscription renewal date.
Moving to a lower level : your account manager will let you know the terms.
