Best practices for importing and segmenting contact lists in Quackdials

If you’ve ever tried to wrangle a messy spreadsheet into a calling tool, you know it’s never as easy as “just upload your contacts.” This guide is for anyone using Quackdials who wants to avoid wasting time, missing leads, or accidentally nuking their entire list. Whether you’re a team lead, SDR, or just the unlucky one stuck with list management, I’ll show you the real-world steps for importing and segmenting contact lists—without losing your mind or your data.

1. Get Your Contact List in Shape Before Importing

Let’s be blunt: most import headaches come from bad data. Spend a little time cleaning things up before you touch Quackdials, and you’ll thank yourself later.

What to do:

  • Standardize your columns. Use clear headers like First Name, Last Name, Phone, Email, Company. Don’t get cute with naming—Quackdials maps best to common field names.
  • Ditch extra formatting. No merged cells, colors, weird date formats, or formulas. Export to CSV. Excel files mostly work, but CSVs are safest.
  • Check for duplicates. If you don’t want to call the same person twice, dedupe now. Tools like Excel’s “Remove Duplicates” or Google Sheets’ “Unique” function work fine.
  • Validate phone numbers and emails. Make sure numbers are in the same format (e.g., +1-555-123-4567 or just 5551234567). At least spot-check a few.
  • Scrub out junk. No empty rows, broken emails, or “N/A” placeholders in important fields. These will trip up the import.

Pro Tip: Don’t overthink it. If your list is huge, focus on the top columns you’ll actually use for filtering or dialing. You can fix the rest later.

2. Map Your Fields Carefully During Import

Once you’re in Quackdials’ import screen, the tool tries to guess which columns go where. It’s usually decent, but don’t trust it blindly.

  • Double-check all field mapping. Make sure Phone doesn’t end up as Company, and vice versa. If something doesn’t look right, fix it before you hit “Import.”
  • Skip what you don’t need. If you have columns like “Notes to Self” or “Favorite Pizza Topping,” leave them unmapped unless they’re really critical.
  • Custom fields: If you want to segment by something unique (like “Lead Source” or “Region”), set up those custom fields in Quackdials first, then map to them.

What NOT to do: Don’t import every scrap of data “just in case.” It clutters things fast and makes segmenting harder.

3. Start With Broad Segments, Then Get Granular

Segmentation is where most folks go overboard. You don’t need a dozen micro-groups right off the bat.

  • Begin broad: Start with basic segments—think “Customers vs. Prospects,” “By Region,” or “By Industry.” These are easy to filter and actually useful.
  • Add tags as you go: As you call or learn more, use tags or custom fields (“Hot Lead,” “Do Not Call,” etc.) to get more specific.
  • Avoid dead-end segments: Don’t create a segment you’ll never use. If you don’t regularly filter by “Trade Show 2019,” skip it.

Honest take: You can always make your segmentation more detailed later. Start simple—you’ll save time and confusion.

4. Don’t Ignore Permissions and Compliance

This isn’t fun, but it’s critical. Make sure you’re not importing people who didn’t opt in, or numbers on do-not-call lists.

  • Permission first: Only import contacts you’re allowed to call. This keeps you out of legal hot water and helps your team avoid wasted dials.
  • Opt-outs and suppression lists: If Quackdials lets you, upload your suppression list (people who shouldn’t be called) before you import.
  • Audit your sources: If you got a list from a third party, double-check it’s legit. “Purchased” lists are usually more trouble than they’re worth.

Pro Tip: Build compliance into your process now, not later. It’s a pain to clean up after a bad import.

5. Test With a Small Batch First

Resist the urge to upload your entire contact universe in one go.

  • Import a sample: Try 20-30 rows first. See how they look, check that segmentation works, and make sure the right fields landed in the right spots.
  • Fix issues early: If the phone numbers are all jumbled, or tags didn’t import, it’s easier to fix with a test batch than with 10,000 contacts.
  • Get feedback: If you work with a team, have someone else check the sample import before you move ahead.

What doesn’t work: “We’ll clean it up after.” You won’t. What you import is what you’re stuck with.

6. Document What You Did (So You Don’t Repeat Mistakes)

You’ll forget what you did in three months, or someone else will have to pick up where you left off.

  • Save import templates: If you use a certain column order or field mapping, keep a copy. Share it with your team.
  • Note custom fields: Write down which custom fields you added and why. Saves future confusion.
  • Log errors or gotchas: If something broke during import, jot it down. Next time will be smoother.

7. Keep Your Lists Fresh

Importing is not a one-and-done task.

  • Schedule regular clean-ups: Outdated contacts clog up your workflows and waste time. Set a reminder every quarter to review and refresh.
  • Remove inactive or bounced numbers: No one wants to call dead leads or wrong numbers. Archive or delete as needed.
  • Update segments: As your business changes, so will your segment needs. Prune old tags and add new ones as you go.

Pro Tip: The best list is a living one. Stale lists kill productivity.

What Actually Matters (And What Doesn’t)

Here’s the honest bottom line:

  • Clean, simple data is better than “comprehensive” chaos.
  • Segmentation should serve your workflow—not just look good in a report.
  • You can always iterate. Don’t let “perfect” slow you down.
  • Ignore “import all the things” advice. Start with what you need, add as you learn.

It’s easy to get lost in the weeds with imports and segmentation. Focus on what helps you reach the right people, with the right message, right now.


Keep it simple: Clean your list, map it carefully, start with broad segments, and test before you go big. Don’t chase perfection—just make it better each time. The rest is just noise.
