I've used Eloqua, Marketo and the likes to automate a lot of processes, run campaigns, and empower sales teams, marketing teams and even management teams and to be honest I have to say that the combination of 1 Mkt automation tool + 1 CRM tool usually gets the job done, but you see, my point is I still have to do a combination. I haven't found any CRM that allows automation the way Eloqua / Marketo do, and haven't found any mkt automation tool that would include a native CRM.
I guess right now the one possible combination that way would be Oracle. By acquiring Eloqua they gained the capability of doing what I just described...I guess.
What do you think?
