Currently, Mailchimp is the biggest Mailing platform in the World. Mailchimp is not the biggest because they offer the best services, they are the biggest for just 2 reasons.
1) They are cheap
2) They are reliable, very high inbox rate.
According to
https://sumo.com/stories/mailchimp-marketing this platform made over $400M in just 2016 with lot of work offcourse and so many years also. The journey to compete can only start from a day.
And what am so confident about is, its not how far you have gone but its how well you have done it. We have decided that we want to compete in this sector with names like Mailgun, Sendgrid and many of them.
We would be glad if someone shares this dream with us also!
