MailChimp
MailChimp is a free website www.mailchimp.com that allows users to create html (graphical) email templates simply and easily. Once a template has been created it can then be sent to a list of Contacts en masse. MailChimp will help manage your mailing list in Acquaint and the emails will track the recipient's interaction and return statistics.
Acquaint can export a list of Contacts and import them into MailChimp, ready to be used in a MailChimp Campaign.
The MailChimp Export function can be accessed via the Miscellaneous tab → MailChimp Export

Click the MailChimp icon located on the Miscellaneous tab of the ribbon menu.
Select the MailChimp List to export to from the MailChimp List drop down list.

By default the MailChimp Export only exports new Contacts that haven't already been exported to MailChimp. If you need to export Contacts that have previously been exported then click the Advance tab and choose Refresh All Contacts On MailChimp. This option will only include them if they're still on the emailing list and are current.
When the Run button is clicked the MailChimp Export process will:
Retrieve a list of unsubscribed members from the selected MailChimp list and remove them from the Emailing List in Acquaint
Export a list of Contacts and import them into the selected MailChimp list
Unsubscribe Contacts from the selected MailChimp list if they've been removed from the Emailing List in Acquaint.
Contacts will only be exported if they match these criteria:
Contact has an email address
Contact is on the Emailing List (tickbox on the Correspondence screen)
Contact has a Status type that isn't set to Exclude from Matches
The free MailChimp account will has a maximum limit of 10,000 emails per month and 2000 contacts with a daily limit of 2,000. This can be increased by upgrading to a paid account. Further information on their pricing is available from www.mailchimp.com
The MailChimp Export includes a custom group call Contact Type that contains each Contacts Acquaint Type. Within MailChimp custom groups can then be used to create targeted campaigns to specific Contacts i.e. just Landlords. MailChimp has a limit of 60 Contact Types that can be imported , when the limit has been reached Contacts are still imported but they will not have a Contact Type. Your MailChimp list will show you what Contact Types are available.
