Connect Your Inboxes to Instantly and Start Warmup

Sign up to Instantly​

Sign up to Instantly. The Growth plan is enough for the setup in this guide. It includes unlimited inboxes and warmup, and up to 5,000 emails per month. Upgrade to Hypergrowth when you need to send more than that.

Add your inboxes​

Instantly connects to Google Workspace with Google sign-in (OAuth), so you don't need to share passwords. You must first allow Instantly in your Google Admin console. You only need to do this once.

Allow Instantly in Google Workspace:

  1. In Instantly, go to Email Accounts > Add New > Google / Gmail / Google Workspace
  2. Choose the OAuth option. Instantly shows a Client ID. Copy it.
  3. In the Google Admin console, log in as your administrator and go to Security > Access and data control > API controls > Manage third-party app access
  4. Select Configure new app, paste the Client ID and select Search
  5. Select Instantly from the results, choose who it applies to (all users), then set access to Trusted and select Finish

Add each inbox:

  1. In Instantly, go to Email Accounts > Add New > Google / Gmail / Google Workspace
  2. Choose OAuth and select Login
  3. Sign in as the inbox you want to add (for example [email protected]) and allow access
  4. The inbox now appears on the Email Accounts page

Repeat for each inbox. Instantly's help center has the latest Google Workspace steps if the screens look different.

Turn on warmup​

On the Email Accounts page, select the flame icon next to each inbox. It changes from grey to a color when warmup is on.

Warmup status in Instantly

Leave the default warmup settings. Instantly increases the number of warmup emails slowly each day. Aim for a warmup health score close to 100% before you start sending campaigns.
