At this time, all email marketing plans include unlimited email sends. This gives you multiple opportunities to market to your clients.
That being said, we recommend not sending more than 1-3 emails per month to any one customer though, so as not to inundate your clients.
*Note - Please review the Terms and Conditions in regards to appropriate email marketing practices (i.e. don’t spam your clients). Should Iris determine users are abusing the unlimited plan, Iris reserves the right to change pricing and email send limits at any time.
