We have a previous sales rep that created hundreds upon hundreds of templates for sequences that are no longer useful to us as she is no longer with the company. To have the ability to "Check All" or delete full folders with templates in them would be helpful for other companies in similar situations. I understand the safety behind it, so maybe have an approval process behind it to avoid any issues. Response from HubSpot Support Agent: 'While you can click the checkbox next to a series of templates listed individually, then bulk delete them via the toolbar, we don't have an option at this time to bulk select all templates on a page or delete a folder with templates. Because of this, you would need to individually select and then delete the templates you're concerned with."
