Email V2 default deduplication settings let you set how marketing and transactional emails deduplicate contacts. By default, deduplication settings are set to Email Only for Marketing Emails and to Email, Name, and Placeholders for Transactional Emails.
Overview of Deduplication Settings and Email Types
Deduplication Settings
- Email Only: Emails send once to each email address, no matter how many times the email appears on the list. This is best for MARKETING emails.
- Email and name – Each recipient with a unique name will receive an email, even if the email address is the same.
- Email, name, and placeholders – The email is only deduplicated if the name, email, and placeholders are all the same.
Email Type
- Marketing: Promotional messages for your event(s). For example, emails promoting a ticket sales launch or price increase for your event. Marketing emails often include system lists (past attendees, donors, etc.), custom contacts, and contacts from your other events.
- Transactional: Emails to attendees, volunteers, donors, etc. with logistical information such as ticket QR codes for easy scanning and check-in details. These emails are not promoting the event, but communicating information about it to those who have signed up.
You can update overall Deduplication settings by going to Email >> Settings. They are automatically set to Email Only for Marketing Emails and to Email, Name, and Placeholders for Transactional Emails.

When you send an email, choose the type of email you are sending. Then you have the choice to override the default deduplication settings. Note how the recipient count updates to include fewer when the deduplication setting is Email Only vs Email, Name, and Placeholders.
