How to Enrich a CSV at Scale with Surfe

TL;DR: Manually enriching CSV lists wastes rep time and fills your CRM with poor-quality data. With Surfe, you can upload a CSV and get verified email addresses and mobile phone numbers straight into your CRM in minutes, at scale.

It may be 2025, but CSV lists are still a standard handoff tool across sales, marketing, and partnerships teams. They often act as the bridge between systems that don’t integrate cleanly – but that doesn’t mean they’re ready to use. And when reps have to manually enrich CSVs, they’re taking precious time away from selling and risking filling the CRM with poor quality data.

For sales leaders, bad data has a knock-on effect: shaky forecast accuracy, slower decision-making, and inflated pipeline coverage. 

Lead enrichment tool Surfe solves the problem for both parties with CSV enrichment designed to scale. Its waterfall enrichment technology pulls from over 15 premium providers, validates results, and removes bad data, to the tune of a 93% accuracy rate compared to the industry’s 60-70% average. Verified emails and direct dials are synced straight to the CRM in minutes, with minimal rep effort required.

Here’s how Surfe delivers cleaner CRM records and stronger pipeline confidence, and gives reps the time to focus on selling, not spreadsheets.

Why CSV Enrichment Still Happens

Every CRM, sales tool, enrichment provider, and marketing platform supports CSVs. But that doesn’t mean they don’t come with challenges: 

• Incomplete data: missing contact data (like email addresses or mobile phone numbers) renders a spreadsheet unusable without manual enrichment.
• Outdated: up to 70% of B2B data decays each year. A CSV is static, and keeping track of changes at scale can quickly become unmanageable.
• Inconsistent: not all CSVs are built the same, which means duplicate entries, personal emails, and invalid data can quickly fill a CRM. Poor data is a shortcut to lost trust in company records.

Unless CSVs are enriched and kept up-to-date, they’re going to lead to wasted outreach, poor CRM health, and unreliable reporting.

Fortunately, these outcomes can stay firmly in our collective imagination with Surfe. Next: how to enrich a CSV at scale.

How Surfe CSV Enrichment Works (In Plain Terms)

Enriching a CSV with Surfe takes just three steps. At the end, you’ll have clean, accurate, up-to-date data in your CRM. Thanks to Surfe’s deduplication efforts and regular scans for job changes, this data will stay up-to-date too: no small feat when you’re working at scale.

Here’s how to enrich a CSV with Surfe:

Step 1: Upload your CSV 

Your CSV should, at a minimum, include the lead’s first name, last name, and company name and/or website.

LinkedIn URLs are an optional addition if you want to increase your match rates. A LinkedIn URL is unique. Point Surfe towards a lead’s unique URL, and you’re pointing it towards the source of truth for that person. This is particularly helpful if there are multiple people with the same name at a large organization. Doing so improves database matching, as Surfe can work from a verified profile, reduces false positives, as it’s relying on up-to-date data, and boosts coverage where a database might lag behind.

Step 2: Click “Find All Emails and Mobiles” 

From here, Surfe uses its waterfall enrichment technology to search for contact data across over 15 premium providers. It validates any email addresses it finds by running them through ZeroBounce and removes invalid, duplicate, or personal records before delivering results.

Working across multiple platforms increases Surfe’s chances of finding an accurate result – particularly if you manage a team working across multiple regions or countries, as often one database will be strong in one or two regions. Consistent coverage across regions will make sure your international pipeline doesn’t stall.

Surfe also boasts a 93% accuracy rate (compared to competitor averages of 60-70%), saving your reps from manually filling in gaps and saving your budget from being wasted on credits that don’t deliver.

Step 3: Export or Sync 

What happens next is up to the user. You can download a fresh CSV or sync the data directly into your CRM. Surfe integrates with all major CRMs used by modern sales teams, like Salesforce, HubSpot, or Pipedrive, for example.

Directly syncing the data into your CRM cuts down the time that enriching your CSV takes. Automating this part of the process leaves reps to move onto the next stage of the process as fast as possible.

Whether they choose to download a new CSV or sync the data directly into their CRM, the result is the same: verified contacts with direct dials and clean records, ready to work immediately.

When to Use CSV Enrichment

Next, let’s look at the best use cases for CSV enrichment with Surfe. Spoiler: Sales, Marketing, and RevOps teams will all find time-saving advantages here.

Marketing to Sales Handoff

If Marketing uses several channels to generate leads, like paid, organic, and events, for example, they’ll likely be sending multiple CSVs to sales. Use Surfe to enrich these CSVs, and sales teams will receive campaign or event lists enriched before they even open them. The beauty here is that whatever the channel is, the data will be kept consistent.

Best for: organizations with a robust marketing function, or Marketing and Sales teams that work closely together.

Database Cleanup 

If your business is over a year old, it’s likely that CRM records will, in some places, have data that’s incomplete, out of date, or fragmented. By downloading CSVs of this data and uploading them to Surfe, teams are able to enrich at scale without compromising on accuracy or speed.

Best for: RevOps teams looking to revamp the way they input data into the CRM, or make sure the CRM is up-to-date and consistent.

Bulk Prospecting 

If your team is prospecting at scale, whether that’s over email or as part of a multi-channel, multi-touch strategy, they’ll need a CSV with ready-to-go leads. Note: this doesn’t just include contact data.

Most lead enrichment tools stop at email addresses and maybe phone numbers (which, with average 60-70% find rates, may or may not be accurate). Surfe also provides technographic and firmographic data, which allows for effective segmentation at scale. The better teams can segment, the better they can personalize outreach, and the better their results will be.

For leaders managing international teams, Surfe’s global coverage ensures consistency across regions – so pipeline quality doesn’t depend on where the data originated.

Best for: Sales teams who rely heavily on outbound prospecting to generate qualified leads.

Partner or Third-Party Lists

Partners or reputable third parties can be an excellent source of quality leads, but they’re unlikely to deliver them ready to use.

Using Surfe to enrich these lists is a quick way to standardize and validate external spreadsheets before they ever reach your CRM, keeping standards high and data clean from the get-go.

Best for: Sales leaders who work closely with partners to generate leads.

ROI of Surfe CSV Enrichment

Let’s look at the big one first: revenue. How do the time savings of Surfe directly impact the bottom line?

Let’s say you manage a team of 10 reps, who each lose 5 hours a week to manual enrichment. That’s 200 hours a month wasted. If each of those hours costs you $100, that’s $20,000 a month spent on admin.

That’s budget that could be directed into growth, and time that could be directed into revenue activities. Pricing for Surfe starts at $17,400, meaning over one year it would pay for itself many times over.

As well as a positive impact on revenue, with Surfe your team will also experience:

• Time saved: let’s take that figure of 5 hours a week spent on enriching CSVs manually. That’s 1/8th of a week gained back.
• Cleaner CRM: when a CRM consistently delivers and doesn’t drain rep time, they trust it. This keeps morale high and stops quality leads from disappearing into unofficial spreadsheets.
• Higher connect rates: when each phone number and email address is verified, your team will have more conversations. In other words, you’re spending their time and money wisely.

Enriching a CSV at Scale: Final Thoughts

The bad news: we may be in 2025, but CSV enrichment is here to stay as a standardized way to transfer data.

The good news: we’re in 2025, which means that CSV enrichment doesn’t have to be done manually.

Using a reliable, high-quality lead enrichment tool like Surfe makes CSV enrichment faster by bulk verifying contacts, filtering out poor entries, and syncing clean data straight into your CRM.

Flexible data transfer without the manual overhead, reliable forecasts, and easier scaling in just three easy steps. If that sounds like something you need, you know what to do.
