How SendQ.io Works
Emails that are sent that are off brand, incorrect, or just wrong are costly to any organization. But who has the time to test every single email before you send it to a customer? With SendQ, you do.
SendQ works with your existing email infrastructure and is easy to setup. You configure your applications to use SendQ with just a few simple steps. Then you set up your tests inside of SendQ. Whenever SendQ receives an email from your application, every test is run, and you can immediately see the results.
You can take this a step farther and setup your SendQ to your existing email platform. Once you do, every email that is sent to SendQ AND passes all of the tests is sent on to your customers. No more mistakes - you can now stop bad emails before they hit the inbox.
SendQ gives organizations the confidence to hit send.
