Email warmup builds your sender reputation by generating positive engagement signals that prove to email providers you're a legitimate sender.
Without warmup, Gmail and Outlook see no track record and filter your emails to spam.
Mailivery fixes this by:
✔️ Connecting your mailbox to a network of real email accounts
✔️ Automatically generating opens, replies, and spam folder rescues
✔️ Signaling to providers that your messages deserve the primary inbox
Connect Gmail, Outlook, and most providers in minutes. Use a native connection when available, or connect via SMTP.
You can connect any email provider on the market to Mailivery, natively or through SMTP.
What you control:
- Warm-up emails per day
- Reply rate and engagement intensity
- Schedule and sending windows
Mailivery's AI automatically sends and receives emails on your behalf, generating the engagement signals providers look for:
What the system does automatically:
- Sends warm-up emails with real content
- Opens and replies to messages
- Moves messages when they land in Spam into the Inbox
- Helps build consistent positive engagement signals
Every interaction tells Gmail and Outlook: "This sender is legit."
Mailbox providers evaluate engagement and consistency to decide whether your emails are wanted. As your mailbox shows stable, natural behavior, your sender reputation improves.
What typically improves
- Domain reputation and mailbox trust
- Fewer sends landing in Spam
- Better placement in Primary or Focused inbox tabs
Monitor your progress in real-time:
- Reputation score per mailbox
- Spam rate trends over time
- Performance by provider (Gmail vs Outlook)
The result: your outreach lands in primary inboxes where it gets read—not spam folders where it gets ignored.
Excellent 4.7 out of 5
The best part of my experience using Mailivery is that it works. I started sending cold emails without doing the research, and tanked my business' domain reputation. We weren't even able to contact our engaged prospects! After just a few weeks using Mailivery email warmup, I'm already seeing a drastic improvement in email deliverability.
Amazing, their customer service has improved 10x since we first started and it's been just about 6 months since we have been with them. It's a team you can rely on. So don't think another minute and sign up!
It's super easy to connect my email accounts and the stats that are shown are super useful. The automated reading and sorting feature has made my life so much easier and really separates Mailivery from other products. Overall it's way better than any other warming software I have used.
Most users see initial improvements within the first week, with significant results by day 14. However, email warmup isn't a one-time process, it's ongoing maintenance.
We recommend keeping Mailivery running continuously to maintain your sender reputation, especially while you're actively sending outreach campaigns.
Yes. Mailivery works with any email provider that supports standard authentication or SMTP connections. This includes Google Workspace (Gmail)*, Microsoft 365 (Outlook), Zoho Mail, Amazon SES, SendGrid, Mailgun, and virtually any other email service.
You can connect multiple mailboxes from different providers in the same account.

Mailivery is designed with safety as a priority. Our AI generates natural, varied email content that doesn't trigger spam filters. We use real email accounts with established reputations, and we automatically rescue any emails that land in spam.
Unlike aggressive warming tools, Mailivery ramps up gradually and follows email provider best practices to protect your domain.
Absolutely. In fact, this is when warmup matters most. When you send cold emails or outreach campaigns, some recipients won't engage,,which can hurt your reputation. Running Mailivery simultaneously generates positive signals that offset any negative engagement, keeping your sender reputation stable even during heavy sending periods.
In most cases, yes. Mailivery can repair damaged sender reputations by generating consistent positive engagement over time. The timeline depends on how damaged your reputation is: severely impacted domains may take 3-6 weeks to recover, while minor issues often resolve within 2-3 weeks. Our dashboard lets you track your recovery progress in real time.
This depends on your plan and settings. You can customize your daily warm-up volume based on your mailbox age, current reputation, and campaign activity. New domains typically start with lower volumes (10-30 emails/day) and ramp up gradually. Established mailboxes can handle higher volumes. Your dashboard lets you adjust these settings at any time.
Mailivery improves reputation at all three levels: your specific email address, your domain, and your sending IP. However, if you have multiple email addresses on the same domain, each address should be warmed individually to generate enough positive signals at the domain level.
Mailivery automatically organizes warm-up emails into a dedicated folder or label, keeping them separate from your real correspondence. You'll see the warm-up activity in your Mailivery dashboard, but it won't interfere with your day-to-day email workflow.
The easiest way to get responses to your cold emails.
