Email Settings

Email Settings is where you configure the email infrastructure your bot uses to send messages — things like password reset links, workflow notifications, ticket updates, and alerts. Some setups also support inbound email (receiving and routing replies through the platform).

Leena AI supports three email setups. Pick the one that matches your organization's existing infrastructure and email needs, then follow the corresponding guide.

Access

All email configuration lives under Unified Dashboard → Settings → Email Settings.

You'll need Config Manager access to see and use this section. If you can't see Email Settings, contact your Leena AI SPOC.

Supported setups

Configuring Office 365 Email

Send email from an existing Microsoft 365 mailbox using Microsoft Graph and app-only authentication. There's no domain authentication or DNS setup involved — instead, your IT admin creates an Azure/Entra App Registration with Mail.Send permission, and the dashboard sends via that specific mailbox. This is the natural choice if your organization is already on Microsoft 365 and has a mailbox you want to send from.

Mailgun Domain Authentication

Authenticate a subdomain (e.g. mail.company.com) with Mailgun, configure DKIM and region options, and create sender and receiver identities. Mailgun supports both outbound and inbound email routing, so it's a good fit if you need to receive replies or route incoming mail through the platform.

SendGrid Domain Authentication

Authenticate your domain with SendGrid and add "From" addresses for outbound email. If your organization already uses SendGrid, you can reuse an existing authenticated domain across multiple bots via the Use Domain ID flow.

Which one should you pick?

In most cases the choice is already made for you — use whichever provider your organization has existing contracts, credentials, or infrastructure for. If you're starting fresh:

• Pick Office 365 if you're a Microsoft 365 shop and want to send from an existing mailbox without touching DNS.
• Pick Mailgun if you want a dedicated email subdomain under your control, or need inbound email routing as well.
• Pick SendGrid if you already have a SendGrid account, or want to share an authenticated domain across multiple bots.

If you're unsure, check with your Leena AI SPOC.
