Mailboxlayer is quite simple to use, and its documentation is useful. If you’re familiar with calling API’s, you shouldn't have issue in using it. It is a good application for identifying spammy and fake email list from the database and helps in removing those list, which finally increases the overall performance of our email marketing campaign.
