Does having good relations (i.e. >100) or previous commitments (vassalage, alliance) make any difference or does everyone simply DOW you? The messages come in so fast I didn't have time, nor the want to, read them all.
Having them both as vassal and in your alliance is the best thing since they act as a buffer against others DOW and having access to you. Better make sure you have mil. Access as well since you will not be inviting them to join your wars.
