TOP 3 best email push Routing Companies

hi guys,

I have a very specific question today

I'm looking for an email routing company -not a software- that can do all the following:
a well known, well established reputable company
compatible with sexy offerings,
affordable cost per thousands,
ensure regularly great deliverability,
push great numbers of emails,
comprehensive interface (so I can upload my push),


if I google I get gazillions of companies, but dont know where to start,
so if someone already knows who to pick,like a top 3 or something,
that would help me greatly!

much appreciated,
thx in advance
