Developer of MailOptin here. We have a client using MailOptin to send emails when posts are created. The problem is the email doesn’t include a featured image.
When using the Post Fields in a form, the feature image gets set before the post is published. As a result, it works with our plugin correctly.
Hi there! I recommend submitting this as a feature request, since it would require making changes to the way the add-on currently performs. You can submit by visiting our product roadmap and scrolling to the bottom, then clicking the blue + button on the lower left.
This is the best way to get a suggestion to our product team. While we can’t promise a specific request will be honored, our developers do take all requests into consideration when planning the future of Gravity Forms and its official add-ons.
