Everything you need to know about email warmup

Got questions? We've got answers. Can't find what you're looking for? Contact us.

Email providers (Gmail, Outlook, etc.) use complex algorithms to decide if your emails deserve the inbox. If you're a new sender or haven't built a strong reputation, your emails get silently blocked—not even sent to spam, just... gone. Studies show 67% of cold emails never reach the inbox. That's the invisible wall. InboxWarm.ai tears it down by building your sender reputation through AI-powered warmup conversations.

Most users see improvements within 3-7 days. Full warmup typically takes 2-3 weeks. Our AI optimizes the schedule based on your account's performance, gradually increasing email volume to build trust with email providers. You'll watch your inbox placement rate climb in real-time on your dashboard.

Absolutely safe. We ONLY interact with the warmup emails we send and receive—never your personal or business emails. All data is encrypted with industry-standard security. We're fully GDPR compliant. Your credentials are stored securely and we never access anything beyond the warmup system. Think of us as a gym for your email reputation.

It means exactly what it says: unlimited email accounts, unlimited warmup emails, one flat price. Whether you have 1 account or 100 accounts, the price stays the same. No sneaky per-account fees. No volume caps. No throttling. Connect as many emails as you need and warm them all simultaneously. This is how pricing should work.

We support all major email providers: Gmail, Google Workspace, Outlook, Office 365, Microsoft 365, and any custom SMTP provider. You can connect using OAuth (easiest, recommended) or SMTP credentials. Setup takes less than 60 seconds regardless of your provider.

Yes, cancel anytime with one click. No long-term contracts. No cancellation fees. No questions asked. You're in complete control. We also offer a 14-day money-back guarantee—if you're not satisfied, we'll refund you in full. We're confident you'll see results, but we remove all the risk.

Absolutely not. If you can send an email, you can use InboxWarm.ai. Our setup is literally: 1) Click "Connect Email", 2) Authorize with OAuth (or enter SMTP details), 3) Done. The AI handles everything else. No configuration needed. No technical jargon. We built this for marketers and sales teams, not engineers.
