[and tactical mix by account priority]
Not all accounts have the same value. Align your approach with revenue potential of the accounts you're targeting.
Split your lists into a small list of big, strategic accounts AND a larger list of named accounts (strong prospects which will still net less revenue per account).
Scale your strategy accordingly: for the strategic accounts, invest in higher-touch, higher-value programs and experiences. For the larger list of named accounts, think about how you invest in customising your messaging and content offers.
