# How to connect GoHighLevel / Lead Connector to MailReach

# Before you begin: what you’ll need


**In GoHighLevel you’ll need SMTP credentials for the sending domain (or sub‑account) that you will use for your cold‑outreach/warm‑up.**
* GoHighLevel provides a way to generate SMTP credentials under *Sub‑account Settings → Email Services → Dedicated Domain → SMTP Settings*. [Access the Article here](https://help.gohighlevel.com/support/solutions/articles/155000002132-where-can-i-find-my-dedicated-domain-smtp-credentials-?)
* Note: Although GoHighLevel has its “LC Email / LeadConnector Email” product, when you want to use a third‑party warm‑up tool (MailReach) the key is *custom SMTP credentials* that MailReach can connect to.

**You’ll also need a mailbox accessible via IMAP** (that is: an “inbox” where replies land) because MailReach uses IMAP to monitor inbound responses (which is critical for its warm‐up and sender reputation logic). 
* You can create a Gmail/Google Workspace or Outlook/Office 365 mailbox for this, or use an existing one where replies are going.

**Make sure your sending domain (in GoHighLevel) has proper DNS/authentication** (SPF, DKIM, etc) so sending through SMTP doesn’t immediately land in spam. GoHighLevel has best‑practices around this.

# 1. Retrieve SMTP credentials in GoHighLevel

1. Log into GoHighLevel and navigate to the **Sub‑account** you will use.
2. Go to **Settings → Email Services (or SMTP & Mailgun Service)**
3. Under “Dedicated Domain / SMTP Settings”, click **Create New SMTP User** and generate a username + password for that sending domain. [HighLevel Support Portal+1](https://help.gohighlevel.com/support/solutions/articles/155000002132-where-can-i-find-my-dedicated-domain-smtp-credentials-?utm_source=chatgpt.com)
4. **Record** the SMTP settings:
    * SMTP server (hostname)
    * SMTP port (often 587 or 465)
    * Username (often the email address or user you created)
    * Password (the SMTP user password you created)
    * In GoHighLevel, you may also need to mark this provider as “Default” for that sub‑account. [HighLevel Support Portal](https://help.gohighlevel.com/support/solutions/articles/48001059689-setting-up-smtp-providers?utm_source=chatgpt.com)

| Optionally: test sending from GoHighLevel using that SMTP provider to verify it works (for example send a test email to yourself). [gohighlevele.com](https://gohighlevele.com/highlevel-help/setting-up-smtp-providers-in-highlevel/?utm_source=chatgpt.com)


# 2. Set up the IMAP mailbox

### 1. Decide **which mailbox** will receive the replies to your outreach emails. 
This could be a Gmail/Google Workspace account, or Outlook/Office 365, or another provider that supports IMAP. We recommend Gmail / Google Workspace.

### 2. For Gmail / Google Workspace
* Ensure *2‑Step Verification* is enabled for the account:

* Create an **App Password** (required when using Gmail with IMAP/SMTP from third‑party tools). 
${frame}[How to set up an App Password](https://www.loom.com/embed/467602878c104ad0acee2d530ac84f3f)
### 3. Record these connection details for the mailbox:

* IMAP host (e.g. imap.gmail.com)
* IMAP port (commonly 993)
* IMAP username (the mailbox email address)
* IMAP password (the App Password if Gmail, or mailbox password)

|| This mailbox will be connected in MailReach so that replies from your campaign senders are captured and threaded. MailReach emphasises the IMAP connect step: “Your IMAP information are the credentials of the inbox where the replies of your recipients land.” [MailReach Helpdesk+1](https://help.mailreach.co/en/article/how-to-connect-with-custom-smtp-imap-to-mailreach-acljqy/?utm_source=chatgpt.com)


# 3. Connect everything in MailReach

Now you switch to your MailReach dashboard. The goal: tell MailReach your sending SMTP provider (GoHighLevel SMTP credentials) **and** your mailbox IMAP credentials.

#### Step A: Connect SMTP in MailReach

1. In MailReach, go to **Connect mailbox → Any other with SMTP** (or “Custom SMTP/IMAP”).
2. Fill in the fields:
    * Sender First Name & Last Name
    * Email address (the sending address you’ll warm)
    * SMTP host (server)
    * SMTP port
    * SMTP username & password (from GoHighLevel SMTP credentials)
    * Plain: leave it like this. It covers 99% of cases. 
    * Check the box Use SSL/TLS if your port is 587. If not, don't check it. 

#### Step B: Connect IMAP in MailReach

1. You'll then be asked for IMAP connection details (the mailbox you prepared).
2. Enter:
    * IMAP host (server)
    * IMAP port (for Gmail it's usually 993)
    * IMAP username (the mailbox email address)
    * IMAP password (for Gmail it's the App Password, not the password of the mailbox)


# 4. Additional key configuration

* **Reply‑to / Forwarding**: In GoHighLevel under *Settings → Email Services → Reply & Forward Settings*, you can set a “Forwarding Address” so that replies to your sent emails are copied/forwarded to your IMAP mailbox. This is important: if replies do not go into the mailbox you connected to MailReach, then the warm‑up will not fully succeed. [HighLevel Support Portal](https://help.gohighlevel.com/support/solutions/articles/48001155000-email-services-configuration-reply-forward-settings?utm_source=chatgpt.com)
* **Domain authentication**: Ensure SPF, DKIM (and DMARC) are configured on your sending domain. GoHighLevel’s Email Sending Guide emphasises these for landing in inbox rather than spam.
