I own EMO in 2 accounts. Both are at Schwab and each account is linked to a different email address.
I have received email solicitations by email for both accounts, but only the ones sent out by the fund family.
And I have received a US post office proxy for 1 account only from Saba.
So for both accounts, the fund family has an advantage since it's much easier to vote on-line. And for Saba, I have only received a solicitation for 1 account.
