Emarsys offers a number of additional features for email, some of which are available by default and some of which need to be requested from Emarsys Support.
The frequency cap lets you set a limit to the number of marketing emails that a contact can receive in a given time period.
When a launch list is generated, the frequency cap checks each contact and sees how many emails they have been sent in the last n days. Those who have reached their limit are removed.
If an email campaign launch is spread over more than one calendar day, either due to versions being so scheduled or due to it being launched close to midnight, the frequency cap will think that each contact in the launch list received the campaign on both days. This can lead to contacts reaching their maximum limit sooner than expected.
If you use Send Time Optimization, the Frequency Cap will apply to each child campaign at the moment of launch.
To turn this feature on, go to the Admin menu and select Frequency Cap.
Then activate the check box and set the number of emails (max. 5) and the length of the time period (max. 7 days).
When the frequency cap is activated, all emails will check their launch lists for contacts who have reached their limit and remove them.
All email types except transactional (event-triggered) emails will add to the frequency count for each contact, regardless of whether they opened them or not.
Event-triggered (transactional) emails do not add to the frequency count. That is, contacts can receive these emails without affecting their ability to receive other mails.
All types of email are affected, that is, contacts will not receive any emails or any sort while they are at the limit.
If you want to be sure that critical emails are still delivered, you can activate the Ignore frequency cap for individual campaigns in the option with these on the Email Settings page.
This option only appears if the frequency cap is turned on. All contacts in the launch list will be sent this email regardless of their frequency count, and depending on the email type, this campaign may also raise the count by one.
Those contacts who have already been sent the maximum in the last n days are excluded from the launch list and are listed under Frequency cap in the table of Number of emails not sent on the Results Summary tab of the email reporting.
