Ask HN: Mailchimp or Sendgrid?

Hello,

A little background, I am building a tiny start up mostly to get me started and get the feel of how things work. The start-up involves sending a relatively small number of emails to verified emails, so no spam, no unsolicited emails. I hate spam and this service actually helping to avoid getting spam!

I am looking to getting sponsorship and for people who have worked with these companies or any other company that is in the business of email, who is more likely to sponsor me?

Thanks,
