What is high-volume email marketing? 

High-volume email marketing essentially means sending a very high number of emails, usually to your entire user list, in one go. This means not dividing or breaking down the list into different segments or sending it to various sets of lists at different times.

In MassMailer specifically, if you want to increase the speed of a high-volume email campaign, you need a powerful emailing infrastructure with a high email deliverability rate.

However, MassMailer usually takes around 1.5 hours to process and send emails to about 10K recipients. This has become a constraint in receiving emails, and many customers have started asking about ways to improve the processing and delivery speed. 

MassMailer’s dependency on the Salesforce and SendGrid processing speeds and resource availability is challenging. Therefore, MassMailer decided to develop a pilot feature that enables users to reduce the overall delivery time for a high-volume email campaign. 

The solution

To navigate the issue effectively, the MassMailer team has designed custom components. These components can effectively split a high-volume campaign into sub-campaigns of 10K each. Additionally, they can process all of them parallelly based on the Salesforce resources availability.


Currently, the feature works for Salesforce Campaign and Campaign members. Here are the key price points for this feature:

  • One-time payment of $999 to deploy the base components
  • Additional customization needed will be $100 per hour
  • The feature also includes a one-hour-long training session for an additional support cost of $100 per hour

How to design custom components in MassMailer 

As soon as the custom Apex Flows are deployed, the team at MassMailer will make the customization necessary as per your requirements. Here is how we do it-

  • The campaign details page will have a button called ‘Split Campaign.’
  • Once the campaign is loaded with the campaign members, you only need to click on the Split Campaign button to split the main campaign into sub-campaigns. For example, if you have 100K campaign members in the main email campaign, you can break it into ten sub-campaigns to speed up the process of sending emails to all users.
  • Once the sub-campaigns are created, you can set up any other fields such as Email Template Id, IP Pool, From Name, From Address, Reply-To, Campaign Type, Campaign Status, and more. 
  • Here the Flow gets triggered based on the Flow conditions and the criteria set up.
  • Sub-campaigns would get processed parallelly to speed up the email delivery.
  • The ultimate processing speeds depend primarily upon the Salesforce and SendGrid processing times and the availability of resources.
