Good email campaigns keep your subscribers engaged without overloading their inbox. The email frequency safeguard feature allows you to set a maximum number of marketing emails each contact can receive in a given period, on a rolling time range basis.
When you turn this setting on, it will automatically apply to the following email types:
Transactional emails, one-to-one emails, feedback survey emails, and emails sent from the conversations inbox are not included in the email frequency cap, and will always be sent to your recipients.
Please note: if there's a specific email that you want all contacts to receive, you can disable the email frequency cap setting on the Recipients tab in the editor. If you use workflows to send essential automated emails, you should disable this setting for each of those emails. Otherwise, emails will not be sent to any contacts who have met the frequency cap.
Please note: the time period you select under Frequency is a rolling time range for each individual contact. For example, if you have two contacts, John Smith and Jane Doe, and your maximum send frequency is 1 email per recipient per week, it will apply independently to John and Jane. If John receives an email on Friday, he cannot receive another email until the following Friday. If Jane receives an email on Wednesday, she cannot receive an email until the following Wednesday.
Please note: the send to more span feature automatically drops any contacts that were included in the original send, and will not help you resend emails that had the email frequency cap enabled.
