WarmInbox: The Email Warmup Tool for Gmail and Google Workspace
Since launching WarmInbox as a Google Workspace add-on, we’ve been focused on one thing—making inbox warmup as effortless and reliable as possible. The goal: help founders, marketers, and small teams get their emails out of spam without needing to understand deliverability tools inside and out.
We’ve been listening closely to early users and recently rolled out a wave of improvements:
Multiple account support: Manage warmup for multiple Gmail addresses from one dashboard
Pause/resume campaigns: Control your warmup flow without resetting anything
User invitations: Invite teammates to manage or monitor accounts
App password updates: No need to start over when credentials change
Cleaner interface: Faster, simpler onboarding and daily use
The billing system is live: Free trial, and subscription management built in
And it all still works through the Google add-on—directly inside your Gmail account.
WarmInbox was built for people who just want their emails delivered. If you're using Gmail (or Google Workspace) for cold outreach or transactional messages, this now runs quietly in the background to improve your sender reputation day by day.
We’d love your feedback if you’ve tried it—and are open to suggestions for getting it in front of more users. Has anyone here cracked early growth with a Google add-on or similar utility tool?
