IntermediateLast updated: 2026-03-26

When to use SMTP/IMAP

Ingegno supports connecting virtually any email provider using custom SMTP and IMAP settings. This guide covers how to set up your email account with manual server configuration.

When to Use SMTP/IMAP

Choose SMTP/IMAP connection if:

  • Your email provider is not Google Workspace or Outlook
  • You prefer manual configuration over OAuth
  • Your organization uses a custom mail server
  • You want to use an app-specific password instead of OAuth
  • Your email provider doesn't support OAuth

Before You Start

To connect via SMTP, you'll need:

  • Your email address
  • SMTP server address (for sending emails)
  • SMTP port number (typically 587 or 465)
  • IMAP server address (for receiving emails)
  • IMAP port number (typically 993)
  • Your email account username
  • Your email account password or app-specific password

Most email providers publish this information in their help documentation. Common settings are listed below for popular providers.

Step-by-step setup

1. Open integrations

There are two ways to reach the email integration settings:

Option A — From Settings:
  1. Click Settings at the bottom of the left sidebar
  2. Select the Integrations tab
  3. Find the Email card and click + or Manage →
Option B — From the Channels section:
  1. Click the chat icon on the far-left sidebar
  2. Under Email, click Account
  3. Add a new account from there

2. Select SMTP/IMAP

On the Connect Email Account page, choose the SMTP/IMAP card — it says "Connect any email provider". Click the Configure SMTP button.

A dialog titled "Connect SMTP / IMAP" will open with configuration fields.

Filling in the Form

Completing the Connection

  3. Ingegno will verify your settings by attempting a test connection
  4. If successful, you'll see a confirmation message

Verify Your Connection

After a successful connection:

  1. You'll be returned to the Ingegno dashboard
  2. Your email account will appear in Channels > Email > Account
  3. Your inbox will begin syncing—this may take a few minutes for the first sync
  4. Incoming emails will appear in Channels > Email > Inbox

Sending Test Emails

Once connected:

  1. Go to Channels > Email
  2. You can compose and send emails directly from Ingegno
  3. Sent emails will use your configured SMTP account

Security & Privacy

Your SMTP/IMAP connection is protected by:

  • Encrypted storage: Your passwords and credentials are encrypted and stored securely
  • Secure transmission: All connections use TLS or SSL encryption
  • Limited access: Ingegno only accesses the email data necessary for the features you use
  • Easy revocation: Disconnect your account at any time from the dashboard

Troubleshooting

"Connection failed" or "Authentication error"

  1. Verify you entered the correct SMTP and IMAP servers
  2. Check that you used the correct username and password
  3. For Gmail, ensure you're using an app-specific password, not your regular password
  4. Verify your email provider's server settings in their help documentation
  5. Check if your email provider requires specific security settings or firewall exceptions

"Port connection refused"

  • Verify the port number is correct (typically 587 for SMTP, 993 for IMAP)
  • Some networks or firewalls block certain ports
  • Try contacting your IT administrator if you're on a corporate network
  • Check your email provider's help documentation for alternate ports

"Email address is invalid"

  • Ensure you entered the complete, correct email address
  • Double-check for typos or extra spaces
  • Verify the domain is spelled correctly

Emails not appearing in Ingegno

  • Wait a few moments for the initial sync to complete
  • Check your email provider's webmail to ensure emails exist there first
  • Verify the connection is still active in Channels > Email > Settings
  • Try disconnecting and reconnecting the account
  • Check if your email account might have security blocks enabled

"Incorrect password" error

  1. Verify you copied your password correctly
  2. For Gmail, confirm you're using an app-specific password
  3. Reset your password with your email provider if needed
  4. Try connecting again with the new password
  5. Contact your email provider if you're unsure about your password

Sent emails not appearing in "Sent" folder

  • This is normal if your provider's IMAP configuration doesn't include the Sent folder by default
  • Ingegno focuses on incoming email management
  • Check your email provider's webmail to verify sent status

Disconnecting SMTP

If you need to remove the connection:

  1. Go to the Channels section > Email > Account
  2. Find your SMTP account
  3. Click to disconnect

Disconnecting

Previously synced emails remain in Ingegno. New emails will stop syncing. You can reconnect at any time.
