Testing your campaign
BrotherMailers spam checker will provide you with a detailed result of how your email scored on the spam system. It will also provide you with information on how to lower the score to ensure maximum deliverability.
BrotherMailer will allow you to send out a percentage of your emails with different subject lines to see which gets the best open rate, you will get real time reporting back on this and you can then send to rest of the emails using whichever subject line is most successful.
BrotherMailer will allow you to send unlimited test sends to 20 email addresses, so you can make sure that they look right before you send them out to your contacts.
Check how your email will look in the recipients inbox to prevent un-opened emails.
