Gmail Email Warmup Tool — Land in Primary Inbox, Not Promotions
If your Gmail emails keep landing in Promotions or Spam, your sender reputation needs repair. InboxWarm.ai automatically fixes this by warming up your Gmail account with real engagement signals that Google trusts.
Gmail warmup is the process of gradually building your Gmail account's sender reputation by simulating authentic email engagement — opens, replies, and inbox interactions. This trains Google's algorithms to recognize your domain as a trusted sender, moving your emails from the Promotions tab or Spam folder into the Primary inbox.
Why Gmail Warmup Matters
Gmail is the hardest platform to crack and also the most important. Google tracks everything: open rates, reply rates, spam reports, and engagement patterns. New or inactive inboxes get flagged instantly.
Without warmup
- Emails → Promotions or Spam folder
- Low open rates → Dead campaigns
- Domain reputation → Damaged permanently
With Inbox Warmup
- Inbox placement improves daily
- Engagement signals increase (opens, replies)
- Sender reputation builds safely over time
Stop Landing in Gmail's Promotions Tab.
Most Gmail senders don't realise their emails are filtered before a single person reads them. InboxWarm fixes your sender reputation automatically — so your Gmail emails land in Primary, every time.

Frequently Asked Questions
Gmail sorts emails into: Primary/Inbox (Personal emails and trusted senders), Promotions (Marketing emails, still seen but lower priority), and Spam (Suspicious or unwanted emails). Our warmup moves emails from Promotions → Primary Inbox.
Typical timeline: Week 1 (System establishes baseline patterns), Week 2 (First improvements in engagement signals), Week 3+ (Noticeable inbox placement improvement of 20-40%).
Both! We can warm up old dormant accounts, new accounts, and accounts with damaged reputation. The process is the same building engagement signals from scratch.
The Promotions tab is triggered by low sender engagement history. Gmail warmup builds the opens, replies, and inbox interactions that train Google to route your emails to the Primary inbox instead of Promotions.
Yes. InboxWarm works with both free Gmail accounts and paid Google Workspace accounts. Connect via OAuth — the setup is identical for both account types.
No. InboxWarm uses human-like patterns with real seed inboxes, not bots. Google sees a healthy, active sender — not automated behaviour. The engagement patterns are statistically indistinguishable from genuine email activity.
Connect your Gmail or Google Workspace account in under two minutes using secure Google OAuth, with no passwords stored and no DNS changes required. Once authorized, InboxWarm begins warming the inbox automatically and you can track inbox placement from your dashboard.
InboxWarm warms up the underlying Gmail or Google Workspace mailbox that actually sends and receives mail. Aliases that send from that same mailbox benefit from its improved reputation, but Google Groups and forwarding-only addresses can't be warmed directly because they don't have a real inbox to send from.
