How many leads do you need for ten meetings?

Set the meetings you want and your expected rates. See the leads, emails, daily sending volume and warmed mailboxes the campaign takes, before you buy anything.

Starting values are cautious assumptions for cold outreach to small businesses, not promises. Move them to match your own results.

To book 10 meetings, you need 1,250 verified leads and 5 warmed mailboxes sending about 188 emails a day. Leads Ranger finds the leads, warms the mailboxes and sends the follow-ups.

  1. 1.Set your meetings goal for the month.
  2. 2.Adjust reply, interest and booking rates to match your own results.
  3. 3.Use the mailbox number to plan warm-up before the campaign starts.

Work backwards, not forwards

Most campaigns start from a list size and hope. Starting from the outcome tells you what the list must be, how many emails that means once follow-ups are counted, and how many mailboxes you need to send it safely.

The mailbox number is the one people miss. Sending too much from too few mailboxes is how good campaigns end up in spam, so warm the mailboxes you need before launch day.

Do this automatically

Leads Ranger finds the leads, warms the mailboxes and spreads sending across them, with follow-ups that stop on reply.

Straight answers

Questions, answered.

It varies widely by market and targeting. Small, well-researched lists with a personal first line do far better than large generic ones. Use your own past numbers in the calculator where you have them.

For cold outreach, a warmed mailbox is usually kept to a few dozen emails a day. Spread larger volumes across several mailboxes rather than pushing one harder.
