Why this addon is  important for email marketers?

We all know that Interspire email marketer (IEM) is the best web based software for email marketing. If you want to send few thousands emails per day and have less number of recipients which are double optin then it is the ideal solution for you even without any addons. But when it comes to mass mailing and to send millions of emails, you need some customization in IEM which can handle that much volume and at the same time you have to bypass spam filter of email service provider by making each email unique from others.  This customization comes in the form of our Addons.

With the help of Multiple MTA addon, you can set each email campaign to use multiple SMTP/MTA account. You can also set SMTPs/MTAs to rotate randomly or in cycle. You will get option to set custom “Mail-From”, “Mail–Reply-To”and “Mail-Bounce-To” with each SMTP account. So this will make each SMTP relay different from others and by rotating set of SMTP during your email campaign, each email have different email header which makes it unique. This will further help you to avoid any footprint and can easily bypass spam filter. Hence, it will inbox well even if you send millions of email.

It also help to take preventive action on low reputed IPs to avoid further damage to its sender score and avoid blacklisting of it.
