Email warmup gradually builds your sending reputation by exchanging real emails with real inboxes. Providers like Gmail and Outlook decide whether you land in the inbox or spam based on that reputation. If you blast thousands of emails from a fresh account, you'll hit spam. Warmup fixes that by sending a small number of real emails over 1 to 4 weeks, building the engagement signals that ISPs look for before trusting a new sender.
AutoMailer uses Mailivery's real warmup network. That means actual email accounts open your emails, click links, and reply to them. ISPs see that activity and treat your account as a trusted sender. Some other tools just loop emails within the same mailbox, which doesn't build real reputation. AutoMailer also includes unlimited warmup on all plans, including free accounts.
Google Workspace (Gmail) and Microsoft 365 (Outlook). Those are the two biggest providers for business email, and both get unlimited warmup through AutoMailer at no extra cost. If you're on a different provider, reach out to our support team and we'll see what we can do.
It depends on your settings and how old the account is. Most users see reputation improvements within 1 to 2 weeks, with best results after 3 to 4 weeks. Brand new domains usually take longer. You can speed things up in the dashboard, but go easy on fresh accounts or you'll risk triggering spam filters. The dashboard shows real-time progress so you always know where things stand.
Yes. That's actually one of the most common use cases. Our Mailivery network sends emails that get opened and replied to, which tells ISPs your account is legit. Over time, that pulls your emails out of spam and back into the inbox. Recovery usually takes 2 to 6 weeks depending on how badly the account is flagged. We also recommend double-checking your SPF, DKIM, and DMARC records while you're at it.
Yes, on every plan including the free one. Warm up as many accounts as you want at no extra cost. There are no seat limits or volume caps on warmup emails. You only pay for premium features, not for warmup itself.
Warmup, sequences, lead finder. Everything you need to run cold email that converts. No credit card required.
