Connecting a Mailbox

This guide walks you through connecting your email inbox (your "mailbox") to Warmerly. Once connected, Warmerly can send warm-up emails and outreach on your behalf, and check your inbox for replies.

There are two ways to connect a mailbox:

  1. One-click connect — for Gmail, Google Workspace, Outlook, and Microsoft 365. No settings to type in. Just sign in.
  2. Manual setup — for everything else, like Zoho Mail, Namecheap Private Email, or any other email provider.

If you use Gmail or Outlook, skip straight to the one-click section below. It's faster and there's nothing to get wrong.

One-click connect (Gmail, Google Workspace, Outlook, Microsoft 365)

If your mailbox is a Gmail address, a Google Workspace address, an Outlook.com address, or a Microsoft 365 work address, you can connect it in a few clicks. You don't need to find any settings, passwords, or codes.

  1. Go to Accounts in your Warmerly dashboard.
  2. Click Connect Gmail (for Gmail or Google Workspace) or Connect Outlook (for Outlook.com or Microsoft 365).
  3. A sign-in window will pop up. Log in with the email address you want to connect.
  4. Approve the permissions Warmerly asks for. This is normal — it's how Warmerly is allowed to send and read email for you.
  5. That's it. Your mailbox is connected.

This method is called OAuth. In plain terms, it just means you're signing in directly with Google or Microsoft, and they hand Warmerly a secure permission slip instead of your password. Warmerly never sees or stores your actual password.

If you don't see your mailbox as connected after signing in, try again and make sure you clicked "Allow" or "Accept" on every permission screen. If it still doesn't work, you can always fall back to manual setup below using an app password (explained further down).

Manual setup (Zoho Mail, Namecheap Private Email, or any other provider)

If your email provider isn't Gmail or Outlook, you'll connect it by typing in your mail server settings yourself. This sounds technical, but it's really just filling in a form with a few values that are almost always the same for a given provider.

What SMTP and IMAP mean

Warmerly needs two pieces of information to work with your mailbox:

  • SMTP is the setting that lets Warmerly send email from your address. Think of it as the "outgoing mail" setting.
  • IMAP is the setting that lets Warmerly read your inbox, so it can see replies and track your warm-up activity. Think of it as the "incoming mail" setting.

Warmerly needs both. Sending without reading means Warmerly couldn't see replies. Reading without sending means Warmerly couldn't actually warm up or send outreach from your address. That's why the manual setup form asks for both an SMTP host/port and an IMAP host/port.

A "host" is just the address of your email provider's mail server (something like smtp.zoho.com), and a "port" is a number that tells the connection which door to use on that server (like 465 or 993). You don't need to understand why these numbers are what they are — just copy them in correctly.

Host and port settings for common providers

| Provider | SMTP host (sending) | SMTP port | IMAP host (reading) | IMAP port | | --- | --- | --- | --- | --- | | Zoho Mail | smtp.zoho.com | 465 | imap.zoho.com | 993 | | Namecheap Private Email | mail.privateemail.com | 465 | mail.privateemail.com | 993 |

If your provider isn't listed here, don't worry. Almost every email provider publishes these settings on their support site. Search "[your provider name] SMTP IMAP settings" (for example, "Bluehost SMTP IMAP settings") and you'll usually find the exact host and port to use within the first result or two.

"My IMAP login is different from SMTP" checkbox

On the manual setup form, you'll see a checkbox labeled "My IMAP login is different from SMTP." For most people, you can leave this unchecked, because most providers let you use the same email address and password for both sending and reading mail.

Some providers — especially business or enterprise email systems — issue a separate username or a separate app-specific password just for reading mail (IMAP), different from the one used for sending (SMTP). If your provider does this, check the box. A second set of login fields will appear so you can enter the IMAP-specific username and password separately.

If you're not sure whether your provider does this, try leaving the box unchecked first. The Test connection button (see below) will tell you right away if the IMAP login needs to be separate.

App passwords for Gmail and Outlook (if setting up manually)

Most people should use the one-click connect method above for Gmail and Outlook. But if you have a reason to set either one up manually instead, both providers usually block your normal account password from being used this way. You'll need to create a special app password instead — a one-time generated password just for this connection.

  • Gmail / Google Workspace: First, turn on 2-Step Verification on your Google account if you haven't already (this is a security feature that asks for a code from your phone in addition to your password when you sign in). Then go to myaccount.google.com/apppasswords and generate a new app password. Use that generated password in the Warmerly form instead of your normal Google password.
  • Outlook / Microsoft 365: Go to account.microsoft.com/security and look for the option to create an app password. Use that generated password in the Warmerly form instead of your normal Microsoft password.

Keep this app password somewhere safe. You can always come back and generate a new one if you lose it.

Test your connection before saving

Before you save your mailbox settings, click the Test connection button on the setup form. Warmerly will try both the SMTP (sending) and IMAP (reading) settings right away.

  • If both succeed, you'll see a confirmation and you're ready to save.
  • If one fails, Warmerly will tell you exactly which one — SMTP or IMAP — so you know which host, port, or password to double-check, instead of guessing.

Always run Test connection before saving. It only takes a few seconds, and it saves you from finding out something's wrong later when your emails silently fail to send or Warmerly can't see your replies.
