MassMailer 4.43 version has the following bug fixes, and other improvements.


Bug Fixes

  1. Campaign Feature
    • There was an issue earlier that not all the campaign members email status gets updated with the right status value such as delivered, open, click etc. Instead it used to remain in the 'New' status even though the emails get delivered. This issue got fixed now.

How to upgrade?

  1. You can click on the MassMailer AppExchange Link and click on 'Get It Now' button. If you did not login to AppExchange yet it will show a login screen so that you can enter your Salesforce Admin credentials to login. Now you can click on 'Get It Now' button once again to install the latest version.
  2. Please make sure that you install for all the users.
  3. A dialog will prompt for permission to approve third-party settings. Select Yes, grant access to these third-party web sites, then click Continue.

  4. If your current MassMailer version is LESS than 4.39, then you will have to make sure that you follow the MassMailer setup once again completely to make sure everything is in place, as we have introduced a lot of features in between.
  5. If your current version is 4.39 or higher then you just have to upgrade to the latest package and click on the 'Finish' button on the MassMailer Setup -> Finish page.
  6. If you do not have the SendGrid API Key you need to make sure that you create one by following the instructions at this link. Please make sure you store this API Key in a secure place since you will need this in the future.

  7. Here are the complete instructions for MassMailer Setup. Please make sure you go through them once again and setup anything missing.
