Connect any email inbox to your AI agents directly

✓ Native Support Works with any mail provider 10-Minute Setup

The IMAP/SMTP integration lets your AI agents send emails directly through your own mail server — not via a third-party ESP. Use it with any provider: Gmail, Outlook, Zoho, IONOS, ProtonMail Bridge, or your company's own mail server.

Setup Guide

Get your SMTP credentials

Most providers give SMTP credentials in your mail settings. Common settings:

Provider	SMTP Host	Port	Notes
Gmail	smtp.gmail.com	587	Use an App Password
Outlook / M365	smtp.office365.com	587	Use your M365 password
Zoho Mail	smtp.zoho.com	587	Enable SMTP in Zoho settings
IONOS	smtp.ionos.com	587	Standard email password

⚠️ Gmail requires an App Password

Go to myaccount.google.com/apppasswords → Create an App Password for "Mail" → use that instead of your Google account password. 2FA must be enabled on your Google account.

Connect in the Hub

Go to Integrations → Support and select Email (IMAP/SMTP). Fill in:

SMTP host — your provider's SMTP server
SMTP port — usually 587 (TLS) or 465 (SSL)
Email address — the from address your agents send as
Password / App password — your SMTP password

Use as support escalation channel

To use IMAP/SMTP as a helpdesk escalation channel (instead of Zendesk/Freshdesk), set these env vars on your customer support agent:

HELPDESK_PROVIDER=imap-smtp
# Credentials stored encrypted via the Hub Integrations page

Common Use Cases

📧 Email digest delivery

The Email Digest agent sends daily summaries from your own branded domain — no "sent via Mailchimp" attribution.

🎫 Support escalation

When no Zendesk or Freshdesk is configured, the Customer Support AI falls back to sending escalation emails to your support inbox.

📤 Follow-up workflows

Invoice Reminder and Follow-Up Nurture agents use SMTP to send time-sensitive outbound emails at scale.

Troubleshooting

❌ Authentication failed

For Gmail, you must use an App Password — not your regular Google password. For other providers, check if 2FA breaks standard SMTP auth.

❌ Connection timeout

Try port 587 with STARTTLS first. If your provider blocks 587, try 465 (SSL). Check your firewall allows outbound connections on that port.

❌ Emails going to spam

Ensure SPF and DKIM records are set for your sending domain. Use a domain you own rather than a free email address for best deliverability.

💡 Deliverability Tips

→ Use a dedicated subdomain: mail.yourdomain.com
→ Set SPF: v=spf1 include:yourprovider.com ~all
→ Enable DKIM signing in your provider's DNS settings
→ Set a DMARC policy to protect your domain from spoofing
