E-mail marketing is the most rewarding form of promotion that churns out the highest ROI for your business. It helps you present your services in an on-point manner to your clients and prospects. To make sure your emails are properly landing into the prospect’s primary mailbox and not in spam, you need to have a good SMTP relay.

SMTP is a kind of ’email transfer agent’ that ensures your emails are being delivered to all your recipients. Simple Mail Transfer Protocol or SMTP is a robust backend that aids your business to send, receive, and relay the messages between senders and receivers. SMTP accurately receives outgoing emails from the sender and delivers to the recipient’s closest server that ensures a higher delivery rate.
