CritSend is the solution for your deliverability issues. Founded in 2007, we developed the first service to face the deliverability challenge of transactional emails. Our goal: Facilitating the delivery of emails in your clients’ inbox. Aware of deliverability challenges, we decided to offer you a complete service to face them. Thanks to our team, you don’t need to worry about Spam issues or deliverability, it’s up to us. Today, we estimate that 20% of transactional emails go into Spam instead of going to the right place: the Inbox.
