Hi @Sigurdur130!
I see what you’re saying - you’d like to find a way to get the HTML of the template from Mailerlite and then copy and paste that into the Zap action. That should work in the Zap. though you would need to edit the html text to add in variables like name, etc. using information from previous steps in the Zap
I don’t use Mailerlite so I’m not sure if there’s an easy way to get the html for a campaign template. I can see that there is a custom HTML option for building a template in Mailerlite, are you able to open an existing template into that? If not, it may be worth getting in touch with the Mailerlite team to ask if there’s a way to export the html of templates.
I hope that helps, please let us know if you have any questions!
