What is awesome with sendybay is their awesome support: they are responsive and fast and their advices were essential to us while being stressed to schedule a bulk email campaign and AWS and other bulk mail platform and mounting a sendy server ourselves made our life miserable.
Then the second awesomeness is the very low cost. With sendy + sendybay + AWS (well tuned) bulk email cost a tiny fraction of big ones like Mailshimp.
I read in another review that sendybay is slow. Actually their technology goes as fast as AWS permit with a typical rate of 14 mail per seconds with max 50K mails / days (AWS usual limit). Review collected by and hosted on G2.com.
I just didn't dislike anything. Now I have to write more because else G2 doesn't let me publish my review! Review collected by and hosted on G2.com.
