A user asked the following question on Reddit.
Does Instantly’s warm-up tool even work with Google since Google banned warm-up? Is there any way to automate warm-up on a Google account?

Yes, both Instantly.ai and Lemwarm.com warmup tools work with a Google Workspace (Gmail) account. Google only banned warmup tools using their API, not using SMTP.
