Thanks Michael. Of course, we're well aware of what our competitors are doing and we're aware that this feature isn't available in Ontraport now, as it is in some other systems.
We've prioritized other projects than this one because in the VAST majority of cases, people who broadcast emails want them out now... not 20% now and 80% in 2 days. Therefore, this feature is left unused 99% of the time. That's not to say it's not useful for a few businesses, but it's never made it to the top of our list.
Of course, as an expert in these systems, you'll also be aware that moving back to ActiveCampaign will cost you literally hundreds of other features... but of course that's your choice to make. Different systems for different folks.
We do agree that Ontramail is due for a refresh, and that's scheduled for next year. It will be rebuilt to roughly match the functionality/UX of Ontraport Pages. Hope that helps you plan.
Thanks for the feedback!
