The Unipile Email API is designed to offer a robust and secure connection to your users' email inboxes, ensuring seamless access to both historical and real-time email data. This API supports comprehensive bi-directional synchronization with full CRUD (Create, Read, Update, Delete) functionalities for a wide range of email providers. Featuring a user-friendly REST interface, the Unipile Email API enables you to execute various operations effectively:

• Retrieve details from email messages and threads, including the content of the message, details about the sender and recipients, and other relevant information.
• Efficiently organize email inboxes by utilizing labels and folders.
• Modify the status of email messages, such as marking them as unread or starring them for importance.
• Send email directly through the API.
• Searches within inboxes to locate specific emails or content.
• Handle and download attachments associated with emails.

Google and Microsoft OAuth Setup

Unipile is compatible with all email providers, including those based on IMAP protocols, without the need for any preliminary configuration. An important step of emails integration in your application, it's necessary you create a application directly on your Google and Microsoft account to got your own OAuth screen to login your users. After creating these applications, you should store the corresponding credentials in the Unipile Dashboard. When your development is finished you need to start verification process from Google who can take weeks before start production.

To gain a comprehensive understanding of this process, you can refer to the Google provider integration guide and the Microsoft provider integration guide, tailored for Unipile API.

Configuration of DKIM, SPF, and DMARC

In most cases, major email providers like Google, Microsoft, and IMAP providers automatically configure DKIM, SPF and eventually DMARC when users set up their internal email systems. If you're simply creating a system for email sync and manual sending from your app, you can bypass managing these settings. Just instruct users to connect their email, ensuring they experience the same delivery results as with Outlook or Gmail.

However, if your system involves outreach or automatic sending at higher volumes, it's advisable to verify the proper configuration of these parameters to ensure optimal deliverability at scale.
