Our Email-SMS-Email service enables SMS messages to be sent and received using Microsoft Exchange. Because we support the Internet standard SMTP and POP3 protocols, there is: No software to download & No plug-in to install. You can have the option of creating an SMTP Connector or we can do all the configuration on our systems. Once configured you simply use Microsoft Outlook to send an email to @esendex.net and we forward it as an SMS message to the destination mobile.
