How to Use Prospeo to Enrich a Trade Show Lead List

The short answer: a badge-scan export of a few hundred names is a Starter-sized job, at $49 a month for 2,000 credits on the pricing page, checked on 26 October 2026: clean the file, run CSV Enrichment on name and company, keep only contacts with a verified email, add mobiles for your top accounts alone, let Claude look for the people Prospeo could not match while a person confirms each one, and import the result into your CRM with the event as its source.

Trade show lists arrive in poor shape. Scanners capture a name, a company and sometimes a job title; the email field is often a personal address or blank, and the follow-up window closes in days, not weeks. Prospeo's CSV Enrichment exists for exactly this kind of file. For plans and credit costs, see the Prospeo glossary entry.

Before you upload:

1. Do the credit sum. For example, 450 scans where 380 match with a verified email, and 60 of those are top accounts that also get a mobile: 320 emails at 1 credit plus 60 mobiles at 10 credits, email included, is 320 + 600 = 920 credits, inside one Starter month. Unmatched rows cost nothing, per the credits article.
2. Use the export you have. Each row needs a full name and company, a profile URL or a work email, per the CSV Enrichment overview. If the scanner caught the company website, keep that column; a name alone matches badly when companies share it.
3. Take the baseline from the last event. Meetings booked within 30 days of your last show, per 100 visitors scanned, is the number this follow-up has to beat.
4. Mind where each detail came from. The visitor gave you the badge data; the email and mobile you add did not come from them, so under Article 14 of the GDPR your first message says where the extra details came from.

Step 1: Clean the scanner export

Open the export in a spreadsheet. Remove your own colleagues, other exhibitors and test scans, merge duplicate rows for people scanned twice, and keep one column each for full name, company, website, job title and any profile URL. Add a column for your own tier, such as A for target accounts, so you can split the file later. The CSV Enrichment overview accepts files up to 20,000 lines, 50MB and 200 columns, as .csv, .xlsx, .xls or .txt.

Step 2: Split the file by tier

Mobile enrichment is a single checkbox per upload, so make two files: the A tier, which gets mobiles, and everyone else, which gets email only. That keeps the 10-credit mobiles for the people your sales team will call.

Step 3: Upload and map the columns

In the left sidebar, under Enrich, click CSV Enrichment, then Enrich a CSV, and choose Enrich People, as the CSV Enrichment overview shows. Upload the first file. Prospeo detects common column names; check each mapping in the dropdown, especially company website against company name, then click Next. CSV Enrichment is available on paid plans only.

Step 4: Choose who comes back, then run it

Pick Contacts with verified email, so the file you download holds only people you can write to. For the A-tier file, tick Enrich mobile as well. Select the person and company fields to include, read the credit cost breakdown, and click Enrich contacts. When it finishes, click Download on the far right of the file's row; the overview notes that the button hides when the page is zoomed in, so zoom out if it is missing.

Step 5: Let Claude look for the missing people, and confirm each one

Some visitors will not match, often because the badge spelled a name or company differently. Connect Prospeo to Claude: in Prospeo, open Integrations, find MCP and click Connect, then in Claude Desktop add the hosted URL https://mcp.prospeo.io as a custom connector and authorise it, per the Claude MCP article.

Paste in the unmatched rows and ask: "For each person, search Prospeo for someone with a similar name at this company, and list candidates with title and location. Do not reveal any emails yet." A person then compares each candidate with the badge: same company, a plausible title, the right country. Only for confirmed matches do you ask Claude to fetch the email. The article prices MCP actions like the app: 1 credit per results page of a search, 1 per email and 10 per email with mobile.

Step 6: Import the file into your CRM

Import the downloaded file into your CRM with a property for the event name and date, so follow-up and reporting both point back to the show. If you work on Growth or Pro with HubSpot or Salesforce connected, Prospeo can also enrich records already in the CRM, per its CRM enrichment overview; for a one-off event file, the CSV route is simpler.

How to know it worked

Three numbers, in order. First the match rate shown in the enrichment's stats: if it is low, the scanner data needs work before the next show. Then the bounce rate of the first follow-up email, which should be low for verified addresses. Then meetings booked within 30 days per 100 visitors, against the last event. A vendor's accuracy figure on its own homepage grades its own homework; the bounce rate of your follow-up is the figure that belongs to you.

What Prospeo's help centre warns about

• The Free plan. CSV Enrichment needs a paid plan, and the Free plan caps a selection at 25 rows, per the free plan article.
• Company names on their own. Many companies share a name; include the website or company profile URL wherever you have it.
• Running the same people twice. Re-enriching a record within 90 days costs nothing, so fixing a mapping and re-running does not double the bill.
• Pipedrive and Zoho. Both take pushed leads, but only HubSpot and Salesforce get CRM enrichment.

FAQ

Can I do this on the Free plan?

Not in bulk. The Free plan's 100 credits a month work in People Search and the Chrome extension, but CSV Enrichment needs at least Starter, per the CSV Enrichment overview.

What if Prospeo finds no email for someone?

No credit is charged, and the row is skipped. Contacts with a mobile also get their email free, according to the credits article.

Can I push the enriched contacts straight to a sequencer?

From People Search or a Prospeo list, yes. The integrations overview offers lemlist, Instantly and Smartlead from Starter, and CRM pushes from Growth. A downloaded CSV file goes in through your CRM or sequencer's own import.
