Please make sure you store your access information in a safe place for any future reference.

 

 

2. Tracking Settings


Before this step, you must first register the domain for your Salesforce site URL.


Salesforce Domain & Site Setup


You must designate the Force.com domain & site that will capture email event notifications for mass mailings. If you already have defined a domain you can skip the instructions to create the domain and directly go ahead and create a site as mentioned below after the following step.


1. To set up a Force.com domain name, click Setup => Develop => Sites. 

                          



2. On the Sites page, enter a domain name, then click Check Availability to verify that the domain name has not yet been used.               

3. Once you choose a domain name that is available, select the box to indicate that you have read and accepted the Site Terms of Use and then click Register My Force.com Domain.



4. Once you have successfully registered your domain, you will have the option to create a site. Click New.       
      

       


5. Name the Site and select Active check box.
6. Add MassMailer Sub URL to the Default Web Address
7. Set Active Site Home Page to sentgrid4sf__SendGridSetup.

Save the changes.

                              


After saving the Site please make sure that copy the Domain Name URL link to create a Remote Site Settings


Note: If you have secure.force.com in the URL then you need to copy that Domain Name URL link that has 'secure' in it.



   

Remote Site Settings Setup

                                                                          

For Setting up Remote Site Settings, you need to follow certain steps:


  • Click on Remote Site settings under Security control section.

              


  • Click on New Remote Site button.



  • Enter Remote Site Name as MassMailer
  • Enter the Remote Site URL that you have copied from the the previous step. 
  • Make sure to add https:// before that domain URL link and set it as Active.

          


  • Click Save.


Event Notification & Stay-In-Touch URL Setup


Now let us form your Event Notification URL:


If your Domain URL contains the word "secure" then include “secure” in your Event Notification URL.


For example, if your Site Domain URL is:


mycompany-domain.secure.force.com


Then your Site URL on MassMailer Event Notification URL page would be:


https://mycompany-domain.secure.force.com/massmailer/services/apexrest/sendgrid4sf/MassMailer_hook


And your Stay-in-Touch Site URL on MassMailer Event Notification URL page would be:


 

 

If your Domain URL DOES NOT contain the word“secure":


For example, if your Site Domain URL is:


mycompany-domain.force.com


Then your Site URL on MassMailer Event Notification URL page would be:


https://mycompany-domain.force.com/massmailer/services/apexrest/sendgrid4sf/MassMailer_hook


And your Stay-in-Touch Site URL on MassMailer Event Notification URL page would be:




Now click on the MassMailer Setup Tab to set up these two URLs


Click (2) Tracking Settings, then click Edit and enter or paste the URLs in the Event Notification URL and Stay-in-Touch Site URL fields.


                           


Once you save your Event Notification URL and Stay-in-Touch Site URL on this screen, you will not have to provide them again.


Company Timezone Setup


You need to set the Company Timezone in this step which is same as your Salesforce Org Timezone.

 

For getting the Salesforce Org Timezone, Follow the steps below:

  • Go to Company Information under Company Profile section.
  • Click Edit.
  • Scroll down and go to Locale Settings and Default Timezone is your Salesforce org timezone. 

         


Email Tracking Settings Setup


You should also enable the tracking options such as Open Tracking, Click Tracking, Google Analytics Tracking, and Unsubscribe Tracking by checking the checkboxes in this page.


Suppress Email Activity Logging


MassMailer logs email events such as open, click, spamreport, bounce, unsubscribe etc. You can suppress logging any of these events by setting up 'Suppress Email Event Logging' field on this page.



Log Activities using Salesforce EmailMessage


Note: Please note that you need to enable 'Enhanced Email' feature in Salesforce prior to setting this up. More details on how to set this up at the this link


More information about Salesforce 'EmailMessage' object is at these links - link1, link2


By default MassMailer logs email activity history using the standard Task object and it is displayed under the Activity History related list. If you enable this option, 'Log Activities using Salesforce EmailMessage' then we leverage the Salesforce 'EmailMessage' object to log the activity history. It is still displayed in the same related list though. Advantage is that you can now see the HTML email with properly format and can also preview the actual email that was sent to any lead, contact, person account, user, case, or the opportunity.



Unsubscribe Groups Setup


MassMailer gives you the ability to create unsubscribe groups that represent types of email that you regularly send to your recipients.


For example: Newsletter, Product News, and Marketing Emails.


You can then give your recipients more control over the types of emails they want to receive by letting them opt out of messages from a certain group. This means getting the right messages to your recipient’s inbox, resulting in a stronger relationship with your recipients and a better sending reputation.


Add an Unsubscribe Group


To add a new group, click the “Add New Group” button under 'Unsubscribe Groups' section by navigating to MassMailer Setup -> Tracking Settings Page.



Then, you will be asked to name your Unsubscribe Group, add the description, and select the 'visibile' checkbox. Click “Create” and you will see your new group in the list of all of your unsubscribe groups.




Edit an Unsubscribe Group


In order to edit an unsubscribe group, you need to log into your SendGrid account with credentials provided to you earlier, and navigate to Suppressions -> Unsubscribe Groups.


To Edit an unsubscribe group, you can either choose “Edit Details” from the gear icon in your unsubscribe group list or you can click the name of your group. From there, you will be able to change the name, description, and default group option of the group and . Click “Save” to keep your changes.




Now go back to your Salesforce instance, navigate to MassMailer Setup -> Tracking Settings, click 'Sync Unsubscribe Groups' button under 'Unsubscribe Groups' section. You will see the changes being reflected from SendGrid to Salesforce.





Delete an Unsubscribe Group


To delete an unsubscribe group, navigate to MassMailer Setup -> Tracking Settings Page, and then select “Delete” button from the list of unsubscribe groups listed under Unsubscribe Groups section.




3. Email Settings


Before you can use the MassMailer Email Wizard to build list views for Leads, Contacts, or Accounts, you need to select which Email field from Leads, Contacts, and Accounts to be used as the 'To' Email field to send mass emails.


From MassMailer Setup tab, Click (3) Email Settings in the side navigation bar, and then click Edit

Then select the Email field for Lead, Contact, and Account from the respective drop down lists and click Save.


You can make ‘Default Bcc Sender’ to true or false. Based on the settings made here, ‘Bcc Sender’ Field is either checked or unchecked in both Campaign and Mass Mailer Email Wizard features.


Click Edit in the below Section and Enter your Global Sender Name, Global Sender Email and Global Bcc Email. Click Save. 


Note: Please note that these values are specific to your organization and you can choose to have <Your Company Sender Name>, <Your Company Email>, <Your Company Bcc Email> values respectively.

                             

                             



 

4. Finish


It is mandatory to do this final step to finish the setup but you would still have to complete the setups mentioned in the sections below.


From the left hand side navigation bar, click on the 'Finish' link and the 'Finish' button. 


You will see a confirmation message:


"MassMailer Setup is almost Finished. Please make sure that you have followed all the steps provided in the Configuration Guide"


                    


 

 


You can auto delete the MassMailer Email Status/Activity History/Email Job Statistics values by setting the Scheduler from MassMailer Setup -> Utilities -> Schedule or Manual


You have an option to auto delete the records that are 30 days, 90 days, 180 days, 365 days older by a recurring scheduled job or one time.


You can also select what types of Email Events you would like to delete such as Open, Click, Bounced etc.,
