Hi @intimorosa 

Thank you for posting your question in the community. Any emails sent - whether as a campaign or flow - will be counted toward your monthly volume. So, you’ll want to make sure your monthly tier has enough to cover all of your monthly campaigns plus the estimated volume sent from your flows.

I hope that helps!

@In the Inbox 

Thanks for the answer. And what about subscription emails (such as registration confirmations or double opt-ins?) Are these also counted in the the monthly emails sent? 

Hi @intimorosa 

Yes, I believe so, but let me loop in @Taylor Tarpley at Klaviyo who might be able to confirm. 

Hey @intimorosa 

Jumping in with an assist! Thanks @In the Inbox for starting the convo! While all of your marketing emails (including abandoned cart) will automatically stop sending unless you upgrade your plan, double opt-in and confirmation emails will still be sent to your customers who sign up through your site.
