Why pre-warmed
A new inbox sends half as much in its first month
New mailboxes have to ramp up slowly or they get flagged. Pre-warmed mailboxes start where a new one ends up after a month.

What are pre-warmed inboxes?
Pre-warmed inboxes are mailboxes that already have a sending history when you get them. Mailbox providers treat them as established senders, so you can send at normal cold email volume from day one instead of ramping up over 3–4 weeks.
How much do pre-warmed inboxes cost?
Pre-warmed plans are $39 for 3, $149 for 12, $339 for 30 mailboxes in the first month. After that they renew at $6–$8 per mailbox per month ($24/month on Starter, $84/month on Growth, $180/month on Pro).
Do I still need warmup after buying pre-warmed inboxes?
Keep a warmup tool running at low volume alongside your campaigns. It keeps engagement signals steady. What you skip is the multi-week wait before you can send real campaigns.
Are pre-warmed inboxes Google or Microsoft?
Both. Jetmail offers pre-warmed Google Workspace and Microsoft 365 mailboxes, so you can match the provider your prospects use or run a mix.
How many emails can I send from a pre-warmed inbox?
We plan for 30 cold emails per mailbox per day. To send more, add inboxes and domains rather than pushing each one harder.
Can I connect pre-warmed inboxes to Instantly or Smartlead?
Yes. Pre-warmed mailboxes connect with 1-click OAuth to 50+ outreach tools, including Instantly, Smartlead and other popular sequencers.
