Connecting Email

Know Reply supports multiple ways to connect an inbox. Choose the method that fits your setup.

Each agent needs its own dedicated email account

Every agent must have a dedicated email address that it owns exclusively (e.g. support@yourdomain.com, hello@yourdomain.com). This is the reply-to address on your outgoing emails — when customers reply to your campaigns, newsletters, or transactional emails, those replies land in this inbox and the agent handles them automatically.

Do not use a personal or shared mailbox. The agent monitors and responds to every message in its connected inbox. Create or designate a separate email account for each agent before connecting.

Gmail (OAuth)

The recommended method for Gmail accounts. Secure, no passwords stored.

1. In your agent settings, click Connect Email
2. Choose Google
3. Click Connect Now
4. Sign in with the dedicated Google account for this agent
5. Grant the requested permissions

Know Reply begins monitoring the inbox within minutes.

Microsoft 365 (OAuth)

For organizations using Outlook or Microsoft 365:

1. Click Connect Email
2. Choose Outlook
3. Click Connect Now
4. Sign in with your Microsoft work account
5. An admin may need to approve the app permissions in Azure AD the first time

After consent, the agent syncs and begins processing.

IMAP / SMTP

For providers that don’t support OAuth (Zoho, Fastmail, Yahoo, custom domains):

1. Click Connect Email and choose SMTP/IMAP
2. Fill in the connection details:

Field	Description	Example
Email Address	The inbox to monitor	support@example.com
Username	Usually same as email	support@example.com
Password	Your email password
IMAP Host	Incoming mail server	imap.gmail.com
IMAP Port	Usually 993 for SSL	993
SMTP Host	Outgoing mail server	smtp.gmail.com
SMTP Port	Usually 587 or 465	587

3. Click Test Connection to verify both inbound and outbound
4. Click Add Account to save

Fastmail	imap.fastmail.com (993)	smtp.fastmail.com (465)
Yahoo	imap.mail.yahoo.com (993)	smtp.mail.yahoo.com (465)

ESP Webhooks

If you send through an ESP like Postmark, SendGrid, or Mailgun:

1. Click Connect Email and choose Webhook
2. Select your provider (Postmark, SendGrid, or Mailgun)
3. Enter your API key
4. For Mailgun, also enter your domain
5. Click Connect Now

In your ESP dashboard, set the provided webhook URL as the Inbound Webhook destination. Replies to your campaigns and transactional emails get forwarded to Know Reply automatically.

Switching connections

You can disconnect and reconnect at any time. Go to the email settings, click the connection, and choose Disconnect.
