You can use transactional emails to: - Send a post-purchase email with details about the purchase/booking. - Help your users reset their password if they forget it. - Confirm an order a user places. - Share delivery tracking details for a purchase (when it ships, is on the way, and is delivered) and take many other actions. You can use the [Content API](https://academy.insiderone.com/docs/create-email-campaigns) to: - Send your already-created email HTML body and other input parameters to the Inone panel so you don't have to add them again. - Send them directly to the Inone panel if you have multiple accounts in Inone and the input parameter values are the same or similar. You can use the [Content Manager API](https://academy.insiderone.com/docs/content-manager-template-api) to: - [Create templates](https://academy.insiderone.com/docs/content-manager-template-api#create-templates) - [Update templates](https://academy.insiderone.com/docs/content-manager-template-api#update-templates) - [Delete templates](https://academy.insiderone.com/docs/content-manager-template-api#delete-templates) - [Duplicate templates](https://academy.insiderone.com/docs/content-manager-template-api#duplicate-templates) - [Get templates](https://academy.insiderone.com/docs/content-manager-template-api#get-templates) - [Search templates](https://academy.insiderone.com/docs/content-manager-template-api#search-templates) - [Create categories](https://academy.insiderone.com/docs/content-manager-template-api#create-categories) - [Get categories](https://academy.insiderone.com/docs/content-manager-template-api#get-categories) ## Related - [Send Transactional Emails via API V1](/send-transactional-emails-api.md) - [Create Email Campaigns](/create-email-campaigns-api.md)
