"My
company was fresh off of getting burned with an attempt at email
marketing with Marketo. We needed to move on to a new tool, but there
was no way I was going to be able to convince them to drop several
thousand dollars more for a little while. Enter the picture, Mass
Mailer. This proved to be the perfect interim solution. It allowed us to
use Salesforce.com's native campaign object without the limitation of
500 emails per day. Mass Mailer was not easy to setup, but the tech
support was top notch and had us up and running lickity split. Mass
Mailer does not send the emails itself. You also have to get a
subscription to Sendgrid, a third party mass sending SMTP service. Mass
Mailer is the tool that gets you past the 500 email per day limit, and
also brings all of the mass email statistics (such as bounces, hard
bounces, spams, sends, opens, etc.) into Salesforce.com. If you are
looking for a sophisticated tool for running dynamic drip email
campaigns, Mass Mailer is not for you. However, if you simply have a
need to get past the daily send limit Salesforce imposes, or just want
to get your feet wet with some very simple email marketing, Mass Mailer
is the way to go. "
