Email API for Bulk Senders
For bulk senders email is super critical. You need to manage multiple sending domains and IPs to ensure that your emails are hitting inbox. Even with good sending behavior you may face issues right from getting IP blacklisted, high bounce rate, high deferral rate or inboxing woes with Hotmail, Yahoo or Gmail.
Our easy API & SMTP relay integration, auto IP warmup, alerts on blacklist, bounce and deferral rate alongwith detailed analytics will ensure that your emails never hit and keep hitting inbox.
