What is the difference between a lead and a prospect?

In everyday use they are interchangeable, but the distinction is useful: a lead is any record on the list, a prospect is one you have verified fits your profile. Making the distinction saves time.

How many prospects do I need?

Thirty companies to begin with. That is enough to tell you within three weeks whether your ideal customer profile is correct. Scaling after validation is safe and easy.

How do I qualify a list?

Four questions: is the need real, is there budget, is your contact in the decision chain, is it on the agenda this quarter. Two failures means remove the record — writing to it costs both time and sending allowance.

Are there prospects in a bought list?

Some, but the proportion is low and a share of the records no longer work. Verify every address before sending, or the bounces will affect everything you send afterwards.

What is a prospect and how do you find one?

A lead and a prospect are not the same thing. The difference, and how to qualify a list down to the second one.

What is a prospect in sales?

A prospect is a company or person who might buy from you but has not yet. It has two tiers: everyone on your list is a lead, and a lead you have verified against your profile is a prospect. The distinction earns its keep because time and sending reputation are both finite. Writing to an unqualified list lowers your reply rate and your deliverability at the same time.

In short

A lead is anyone on the list; a prospect is a lead verified against your profile.
Four checks qualify a lead: need, budget, authority and timing.
If two of the four fail, removing the record beats emailing it.
Emailing an unqualified list costs you reply rate and sending reputation together.

Lead versus prospect

A lead is any record that has reached you: a card from a trade fair, a company pulled from a directory, someone who filled in a form. Nothing about it has been verified.

A prospect is a lead you have confirmed fits your profile. The difference is not information, it is filtering, and filtering is where sales recovers the most time.

The four checks

Whether a lead is a prospect comes down to four questions. All four passing means it is worth writing to. Two failing means remove it.

Need: does the problem you solve actually exist at this company?
Budget: have they allocated money, or could they?
Authority: can the person you are writing to decide, or reach whoever does?
Timing: is this on the agenda this quarter, or next year?

Where prospects come from

Source depends on who you sell to. Selling domestically to businesses, chamber of commerce registries, trade fair catalogues and industry directories are free and well populated. Selling internationally, the large databases are faster.

Whatever the source, the order is the same: find the companies, identify who decides there, verify the contact detail. None of the three can be skipped.

Three agents run the part of these steps that repeats every week: defining the audience, building the list, writing each email for the person, and following up on the reply.

How big should the list be?

Thirty companies to start. Thirty records tell you within three weeks whether your profile is right. Starting with three hundred means being wrong three hundred times.

Once the profile is validated, scaling is easy. Measure accuracy first, then increase volume.

The two costs of an unqualified list

The first is reply rate: an email to a company outside your profile goes unanswered, and you cannot write to that person again.

The second is sending reputation. Emails to dead addresses bounce, and once bounce rate passes roughly two percent, the rest of your mail starts landing in spam.
