Enable Batching Multiple Emails

Updated
The Goal: Enable the GrowthZone SuperAdmin-only batching setting to improve email send performance and reliability for larger customers experiencing delays when sending large volumes of email.

Before You Begin:

  • This is a GrowthZone SuperAdmin-only setting — it is not visible to customers.
  • Please reach out to Julie Rayhorn before enabling this for a customer to confirm they are a good fit.

Background: Legacy vs. Batching

Legacy (old) behavior: GrowthZone takes the email, populates merge fields, deduplicates the list, and sends to SendGrid. SendGrid sends in chunks of 1,000 emails.

Batching (new) behavior: GrowthZone takes the email, collects merge field data but does not populate it, then sends the email + data to SendGrid. SendGrid populates and sends in chunks of 250.

How to identify which mode was used in SendGrid: Under Delivery → More Details → Unique Args: if "DM - Batching" is displayed, the email used the new code; if "DM - Legacy" is displayed, the tenant is using the current code.

What Batching Does

Batching contributes to both performance and reliability. Multiple smaller batches improve failure retry logic and can allow GrowthZone to process email sending in parallel.

How to Enable

  1. Go to Marketing & Communication, Communication section, click Settings, then navigate to Email Settings > SendGrid Settings > Enable Batching Multiple Emails.
  2. Enable the Enable Batching Multiple Emails toggle.

When Batching Is Used

Once enabled, batching is implemented when an email is sent using the Send Email screen, including emails sent:

  • From the Standard Email Editor / the "Send Email" window
  • From Email Designer
  • Directly to a list/committee (go to Contacts, click All Lists/Committees, select a list, click Send Email)

Batching is NOT used for: automated emails (event confirmations, Marketing Automation workflows) or billing emails (Pending Delivery → Email Invoices, or Sales/Invoices → Email Invoices/Statements or Email Grouped Statements) due to PDF attachments.

Common Pitfalls

  • Batching does not apply to automated or billing emails: Do not enable batching expecting it to improve performance for automated event confirmations, Marketing Automation workflows, or billing email delivery — it is not used for those send paths.
