Are you wondering why your email campaign didn't send to as many recipients as you anticipated? Start by checking what the Contact Interval Rule is set to on the email campaign.

What is the Contact Interval Rule?

The Contact Interval Rule is set up to prevent guests from receiving multiple email campaigns within the specified time frame. The number represents number of days.

For example, if the Contact Interval Rule is set to 1 and you send a Marketing email in the morning and then another Marketing email in the afternoon, anyone who received the first morning campaign will not receive the second afternoon campaign.

Checking Contact Interval Rule from the Home Page

If you notice on the Home Page that an email campaign didn't send to as many guests as expected, select the hyperlinked number under Sent.

The new window will display what the contact rule was, when the campaign went out, and what the contact interval rule is set to. 

How to edit the Email Type Settings

The Email Type is where the Contact Interval rule is defined. To edit the Email Type navigate to the Campaign Details and select the hyperlinked Email Type. 

Click on the Email Type to open the Email Type Settings. You will see the first setting listed is Contact Interval Rule.

Select Edit

Update the number. Remember it represents number of days. Then select Update.

Warning
Updates made to this Email Type will affect all campaigns using this Email Type 

Another Email Type setting related to Contact Interval Rule is whether the rule is based on the Email Type or not. If Yes is selected, then guests who receive Transactional Email Type (or any other Email Type) will still receive Marketing Email Types regardless of send frequency.
