MxGrid eliminates the need to set up a domain for high volume sending and seamlessly\u00a0adds DKIM signing and SPF authentication to all outbound messages.<\/p>\n<p>MxGrid is a lightweight\u00a0SMTP solution that provides clients with an\u00a0outgoing server, user name and password to connect to\u00a0Greatmail&#8217;s\u00a0SMTP mail servers. The service is compatible with any mail program that supports SMTP including popular mail clients like Microsoft Outlook, Thunderbird as well as Apple mail programs. MxGrid can also be used as the SMTP server for web based applications like Interspire&#8217;s Email Marketer.<\/p>\n<p>MxGrid\u00a0evolved out of\u00a0an emerging\u00a0demand from customers requiring a simple SMTP service for high volume\u00a0mailing applications. Cloud developers, email marketers and anyone sending transactional messages can all take advantage of this service.<\/p>\n<p>One of the main concerns of SMTP customers is maintaining their business identity in their mailings. MxGrid solves\u00a0this\u00a0problem by allowing users to specify addresses at their primary domain in the message From: and Reply-To: headers. The only references\u00a0to MxGrid are behind the scenes in the message Return-Path and SMTP authentication headers.<\/p>\n<p>MxGrid customers must agree to\u00a0follow CAN-SPAM guidelines and adhere to industry standard double opt-in permission based sending. In addition, customers must remove addresses from unsubscribe requests and undeliverable messages. In the event a client&#8217;s mailings\u00a0generate a high percentage of ISP feedback complaints or result in a blacklisting, Greatmail will immediately terminate\u00a0the user&#8217;s service.<\/p>\n<p>To learn more, please visit our <a title=\"MxGrid SMTP Service\" href=\"http:\/\/www.greatmail.com\/mxgrid-smtp-service.php\">MXGrid\u00a0SMTP Service<\/a> page.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Greatmail now offers an easy to use SMTP service, MxGrid, for\u00a0high volume\u00a0email applications.
