Mail AI works by receiving a copy of your customer emails, summarising them with AI, and alerting you on Telegram or WhatsApp. For this to happen, Gmail needs to forward a copy of each incoming email to your Mail AI inbox address.
This guide walks you through the exact setup. It takes under 3 minutes, and you only do it once per Gmail address.
Forwarding is the inbound layer — it sends incoming emails to Mail AI so the AI can read and summarise them.
SMTP is the outbound layer — it lets Mail AI send replies from your Gmail address.
You need both. This guide covers forwarding. Once done, set up Gmail SMTP →
How It Works
Your original Gmail inbox is untouched — Gmail keeps a copy as normal. Mail AI only sees what Gmail forwards to it. It cannot access your Gmail account, read old emails, or log in on your behalf.
Step-by-Step Setup
-
1Copy your Mail AI inbox address
In your Mail AI dashboard, go to Linked Email Accounts and click + Link New Email. Copy the unique forwarding address shown (e.g. [email protected]). You will paste this into Gmail in the next step.

2Open Gmail Forwarding Settings
Sign in to Gmail. Click the gear icon (top right) → See all settings → open the Forwarding and POP/IMAP tab.
Open Gmail Settings → -
3Add your Mail AI forwarding address
Click "Add a forwarding address". Paste your Mail AI inbound address (e.g. [email protected]) → click Next → Proceed → OK.
Open Gmail Settings → -
4Confirm the verification email in Mail AI
Google sends a verification email to your Mail AI address. Go to your Mail AI dashboard → Inbox. Open the verification email from Google and click the confirmation link inside it.

5Enable forwarding and save
Back in Gmail Settings → Forwarding tab, select "Forward a copy of incoming mail to [your Mail AI address]". Choose what to do with the original (keep, archive, or delete). Click Save Changes.
Open Gmail Settings → -
6Link the Gmail address in Mail AI dashboard
Return to Mail AI → Linked Email Accounts → enter your Gmail address (e.g. [email protected]) → click Save. Mail AI now knows which email address incoming forwarded messages belong to.

Want to Forward Only Business Emails? Use a Gmail Filter
By default, Gmail's forwarding rule sends every incoming email to Mail AI — including newsletters and personal messages. If you want only customer emails to reach Mail AI, use a Gmail filter instead.
- In Gmail, go to Settings → See all settings → Filters and Blocked Addresses
- Click Create a new filter
- Set your condition — for example, From: @yourdomain.com, or a specific subject keyword
- Click Create filter → tick Forward it to → select your Mail AI address
- Click Create filter to save
Troubleshooting Common Issues
Verification email never arrived in Mail AI
Double-check that you copied your Mail AI inbound address exactly — no extra spaces or missing characters. Then in Gmail's Forwarding settings, remove the address and add it again to trigger a fresh verification email. Verification emails usually arrive in Mail AI within 30 seconds.
Emails are not appearing in Mail AI after setup
Make sure you completed all three things: (1) added and verified the forwarding address in Gmail, (2) enabled forwarding and clicked Save Changes in Gmail, and (3) linked your Gmail address in the Mail AI dashboard. All three must be done for emails to flow through correctly.
I use Google Workspace — is setup different?
The steps are identical for Google Workspace accounts. However, if your IT admin has disabled email forwarding at the domain level, you will need to ask them to allow it for your account. Alternatively, your admin can set up a routing rule at the domain level in the Google Admin Console under Apps → Google Workspace → Gmail → Routing.
Next Step: Set Up Gmail SMTP for Replies
Forwarding handles the inbound side — Mail AI can now receive and summarise your customer emails. To complete the setup, connect Gmail SMTP so that Mail AI can send replies from your Gmail address when you click Reply in the dashboard.
