How to use Fullenrich to clean and update outdated prospect records

If you’ve ever tried to run a sales campaign with a messy prospect list, you know the pain. Old emails bounce, phone numbers are wrong, and you waste time chasing ghosts. This guide is for sales, marketing, or ops folks who want to actually fix their database—without getting buried in tool hype or endless busywork.

Fullenrich (see here) promises to clean up your prospect records and fill in missing info. It can help, but only if you know what you want out of it and skip the features you don’t need. Here’s how to use Fullenrich to get your data back on track, with zero nonsense.

Step 1: Figure Out What “Clean” Actually Means for You

Before you hit “upload,” decide what you care about. Don’t try to fix everything at once.

Ask yourself: - What fields actually matter? (Email, phone, company size, etc.) - What’s the minimum info you need to run your campaigns? - Are there regulatory or privacy concerns? (GDPR, etc.)

Pro tip: If you try to update every possible field, you’ll end up with a lot of filler data. Focus on the stuff you’ll actually use.

Step 2: Prep Your Prospect List

You need a decent starting file. Fullenrich can’t clean up pure garbage, and it won’t magically turn a list of “John at Acme” into gold.

Do this before uploading: - Export your data to CSV or Excel. - Remove obvious junk: empty rows, obviously fake entries, duplicate contacts. - Make columns clear—label things consistently (e.g., “email”, not “e-mail address”). - If possible, split names into “First Name” and “Last Name.” Tools work better with clean columns.

Don’t obsess over every detail, but do a quick sweep. The cleaner your upload, the better Fullenrich will work.

Step 3: Upload Your Data to Fullenrich

Now you’re ready to feed Fullenrich your file.

  1. Log into Fullenrich.
  2. Find the “Upload” or “Import” feature (usually right on the dashboard).
  3. Choose your cleaned CSV/XLSX file.
  4. Map your columns to Fullenrich’s fields. Double-check that email, phone, and company name are mapped correctly. Skip fields you don’t care about.
  5. Select which enrichment options you want (more on this below).

Honest take: Most tools, Fullenrich included, will try to upsell you on enriching every field under the sun—social profiles, tech stack, job titles, whatever. Only select what you’ll actually use in the next 3-6 months.

Step 4: Choose How You Want to Enrich and Clean

Fullenrich can fill in missing info, check for old emails, and update job titles, among other things. Here’s what’s usually worth your time:

  • Email Verification: This is non-negotiable. Old emails bounce, and nothing kills deliverability faster.
  • Phone Number Updates: Great if you cold call. Skip if you never call.
  • Company Details: If you segment by company size, industry, or location, have Fullenrich fill these in.
  • LinkedIn/Profile URLs: Handy for research or outreach, but only if you actually use them.

What to ignore: Excess enrichment (like tech stack, social accounts, or obscure firmographics) unless you have a clear use case. More data isn’t always better—it’s just more to manage.

Step 5: Run the Enrichment and Wait

Once you’ve chosen your options, kick off the process. Depending on your list size and what you’re enriching, this can take anywhere from a few minutes to several hours.

  • Fullenrich usually emails you when it’s done.
  • Larger lists or heavy enrichment = longer waits.
  • Don’t be surprised if some records can’t be enriched. No tool has 100% coverage.

Watch out: If your list is huge, consider breaking it into chunks. That way you can spot issues early and avoid burning through your entire budget on one batch.

Step 6: Review and Spot-Check the Results

Don’t trust any tool blindly. Download the enriched file and check:

  • Are the critical fields (email, phone, company) actually updated?
  • Do the new values look plausible? (If everyone suddenly works for Google, something’s broken.)
  • Are there obvious mismatches or junk entries?

Pro tip: Check a handful of records by hand. Look them up on LinkedIn or the company website. If you spot a lot of errors, don’t import everything—reach out to Fullenrich support or rerun the batch with tighter settings.

Step 7: Update Your CRM or Outreach Tool

Once you’re happy with the cleaned data:

  1. Back up your current CRM or outreach list. You’ll thank yourself if something gets screwed up.
  2. Import the cleaned, enriched file. Most CRMs have a way to map new data to existing records—double check your matching fields (usually email address).
  3. If you’re unsure about overwriting data, import to a test list first, or only update select fields (like phone or job title).

Don’t: Overwrite your whole database unless you’re sure. It’s way easier to add new info than to recover lost data.

Step 8: Set a Simple Maintenance Plan

Even the best enrichment is out of date in a few months—people move jobs, companies go under, emails change.

  • Schedule a quarterly (or at least twice-yearly) run with Fullenrich.
  • Only update the records you actually plan to use. No need to refresh your whole database every time.
  • Keep your field mapping and enrichment settings handy, so you’re not reinventing the wheel each time.

What Works, What Doesn’t, and What to Ignore

What Works

  • Email verification and basic updates: Keeps your campaigns from bouncing into oblivion.
  • Selective enrichment: Focused updates give you a cleaner, more usable file.
  • Regular spot-checks: Catch errors before they land in your CRM.

What Doesn’t

  • Over-enrichment: More fields mean more room for errors and clutter.
  • Blind trust: No tool is perfect. Always check a sample of the results.
  • Trying to automate everything: Some data just can’t be fixed by software.

What to Ignore

  • “Insights” or “AI suggestions” you don’t need.
  • Fancy dashboards, unless you have a real analytics process.
  • Add-ons that sound cool but don’t fit your workflow.

Wrapping Up: Keep It Simple, Iterate Often

Cleaning up your prospect records doesn’t have to be a nightmare. Use Fullenrich to fix what matters, skip what doesn’t, and check the results before you import. Don’t get caught up in the noise—just focus on keeping your core data accurate, and set a reminder to do it again in a few months.

No tool can make your list perfect, but with a little discipline and regular check-ins, you’ll avoid the worst headaches. Keep it simple and keep moving.
