I love the support that works! I’ve had an awful experience with a big platform where they kept me waiting with no reply forever. This support is fantastic in comparison. They are a small shop, and it shows. They care and are happy to help. Review collected by and hosted on G2.com. What do you dislike about Coresender? There’s no free plan. We send a lot of messages but I know for some users who send only a handful of emails a day, this will certainly be a dealbreaker. Review collected by and hosted on G2.com. What problems is Coresender solving and how is that benefiting you? I send mainly transactional emails, and my customers get the messages, they don’t have to search for emails in spam folders, and this is what I want. The UX is simple and straightforward, and the user experience is intuitive. The setup is quick and painless. Review collected by and hosted on G2.com.
