What the data shows

Most campaigns run to a few hundred leads. Half target 499 or fewer.

The spread is wide. The largest 25% of campaigns are about four times the median, and the largest 5% are almost 20 times.

Small campaigns leave little room for results. At the median 135 contacts per reply, a campaign of 87 leads would expect less than one reply, and a median campaign about 4.

How this compares with common advice

Few guides give a benchmark for campaign size. This data fills that gap. The typical campaign targets about 500 leads, and three in four stay under about 2,000.

What this data can't tell you

Campaign size doesn't predict results in this data. It shows how many leads senders load, not which size works best. The reply figures above are arithmetic on the median reply rate, not results measured by campaign size.

How to use these benchmarks

Frequently asked questions

How many leads should be in a cold email campaign?

The median campaign targets 499 leads, and half of all campaigns fall between 87 and 1,961. At the median 135 contacts per reply, 499 leads would bring in about 4 replies.

Is a bigger cold email campaign better?

Not by itself. This data doesn't link campaign size to reply rate. A bigger list brings in more replies only if the reply rate holds.

How many leads do I need to get 10 replies?

About 1,350 at the median 135 contacts per reply, or about 700 at the top 25% rate of 70 contacts per reply.

Methodology

More than 850 million emails sent through Smartlead, using combined, anonymous platform data only. Only senders with at least 500 emails sent in the period are included. Campaign size is the number of leads loaded into each campaign. Replies are estimated by dividing leads by 135, the median contacts per reply.
