Nah, they have no issue with a tautological definition. “A woman is a female human that’s born a girl” makes perfect sense to anyone that’s asking anyone else to define what a woman is.

Marketing is a very broad term, what does that mean to you?

Constant contact and twilio might meet your needs depending on what they really are.

For which aspect? Sales force does so much that there isn’t a one product alternative. It is, however, cheaper for an enterprise to hire a team of web developers and build a custom in-house solution.

Compete? They don’t need to compete. Their vendor lock in strategy is unbeatable. I have no idea how they continue to scam companies onto their platform, but I don’t know anyone that’s happy with it after a few years (except that one ass hat at every company that somehow keeps moving more business processes to it), and yet I’ve never seen any company successfully get off it.
