List selling and list rental is a thing--a thing HRC has a history of doing.

Here's Hillary's 2009 Leadership Super PAC (Hill PAC) paying her campaign to rent her e-mail list (Twice as much as it contributed to down ballot races, btw).

Two direct quotes from the above link:

" “The evidence does suggest Hill PAC was used primarily as a slush fund to subsidize Clinton’s presidential campaign, using money raised outside of the limits that apply to the campaign itself, rather than as a fund to support other candidates,” said Brendan Fischer, a campaign finance expert at the Campaign Legal Center, a nonpartisan group that supports campaign finance reform."

"He said the list rental price, at approximately $600 per 1,000 names, represented the “fair market value” for a multiple-use rental. He said “pricing validation from commercial vendors was used, along with the most recent past presidential campaign at the time, which was Kerry ’04.”

Around the same time, the Clinton Foundation, the Democratic Congressional Campaign Committee, the DNC Federal Fund, the Presidential Inaugural Committee, and the American Democracy Institute paid $274,297, which Merrill said was the rate for a one-time rental. Other groups paid less."

So the HRC 2008 presidential campaign, which was $23 million in debt, was paid over $2 million for use of their "list", including the most by an HRC Super PAC. it almost seems like, if they really wanted to help those organizations, they would share the list for free (or a nominal fee).
