If you’re using Seamless to build prospect lists or keep your CRM data clean, you already know one thing: bad contact info wastes everyone’s time. Bounced emails, dead phone numbers, and awkward “Sorry, wrong person” calls aren’t just embarrassing—they kill momentum. This guide walks you through exactly how to verify contact information inside Seamless, with some honest pointers about what actually works and what’s just busywork.
Who’s this for? Sales reps, SDRs, recruiters, or anyone who’s tired of chasing ghosts instead of real leads.
Why Bother Verifying Contact Info Anyway?
Let’s be blunt: Most databases, Seamless included, aren’t magic. They pull from the same public and third-party sources as everyone else. That means there’s bad data. If you skip verification, your email campaigns get ignored (or worse, flagged as spam), your dialer fills up with duds, and you waste time explaining mistakes. Verifying contact info is less about being a perfectionist, and more about respecting your own time.
Step 1: Gather Your Contacts in Seamless
Before you can verify, you need a list. Here’s how to get started:
- Log in and set your search filters. Use company, title, location—whatever matters for your campaign.
- Add contacts to a list. Don't just export right away. Keeping them in a Seamless list helps you track what you’ve verified and what you haven’t.
- Export if you want extra flexibility. Sometimes, it’s easier to spot-check or bulk-verify outside Seamless. More on that later.
Pro Tip: Don’t grab huge lists just because you can. Smaller, targeted batches are easier to verify and keep updated.
Step 2: Use Seamless’s Built-in Verification Tools (But Don’t Trust Blindly)
Seamless pitches “real-time email verification” and “verified direct dials.” These sound great, but here’s the unvarnished truth:
- Email “Verified” Status: Seamless uses a background check (SMTP ping, etc.) to guess if an email is valid. It’s right… most of the time. But sometimes it marks catch-all domains as “verified” even if there’s no real person behind them.
- Direct Dials: Same story. If Seamless says it’s a direct dial, that’s better than a generic company line, but don’t expect miracles—some numbers are recycled, disconnected, or just wrong.
How to check in Seamless:
- Open your contact list.
- Look for verification badges (usually green checkmarks or “Verified” labels).
- Sort or filter by verified status to prioritize your outreach.
What to ignore: Don’t waste time on “guaranteed accuracy” claims. Always assume there’s a margin of error.
Step 3: Spot-Check High-Value Contacts Manually
If you’re serious about results, don’t just trust the tool. For decision-makers or big accounts, do a quick manual check:
- Google the email address. See if it pops up on LinkedIn, company websites, or recent press releases.
- Check LinkedIn profiles. Does the person still work there? Did their title or company change?
- Use email verification tools. Free tools like Hunter, NeverBounce, or Zerobounce can double-check if an email is deliverable. They’re not perfect, but add another layer.
Pro Tip: If you’re only sending a handful of emails, it’s worth the extra 30 seconds. For big lists, prioritize your top prospects.
Step 4: Run Bulk Verification (If You’re Working at Scale)
Let’s say you’ve pulled a few hundred contacts. Trusting Seamless’s built-in status is tempting, but if you’ve ever sent a campaign and watched half bounce, you know better.
Here’s how to do a bulk verification:
- Export your Seamless list as a CSV.
- Upload the file to a bulk email verifier (e.g., NeverBounce, ZeroBounce, BriteVerify). These cost a few bucks, but they flag invalid, catch-all, and risky emails.
- Review the results.
- Valid: Good to go.
- Invalid: Delete or skip.
- Catch-all: Decide if you want to risk it—these domains accept all emails, so real delivery isn’t guaranteed.
Don’t Overdo It: For smaller batches or low-stakes campaigns, Seamless’s status is usually enough. But for big sends or important prospects, this extra step saves headaches.
Step 5: Cross-Check Phone Numbers
Seamless claims to provide direct dials, but the reality is mixed:
- Test-dial a few numbers. Before you blast out a call campaign, try a few numbers yourself.
- Look for patterns. If you get lots of switchboards or generic voicemails, the data’s probably stale.
- Use LinkedIn or company directories. Sometimes you can find direct lines or extensions posted openly.
What to skip: Don’t bother running phone numbers through fancy validation tools—they’ll only tell you if a number is active, not if it’s the right person.
Step 6: Update Your CRM or Outreach Platform
Once you’ve verified (as much as is practical), sync the clean data back to your CRM or outreach tool:
- Tag or note verification status. Mark which contacts are fully verified, spot-checked, or just “as-is” from Seamless.
- Remove obvious duds. If an email or phone is confirmed bad, delete it now. Don’t assume you’ll clean it up later.
- Set reminders to re-verify. Data goes stale fast, especially in industries with high turnover.
Pro Tip: Don’t overwrite existing good data with new, unverified info. If you’re not sure, keep both fields until you confirm.
What About Automation and Integrations?
Seamless plays nice with a lot of CRMs and outreach tools. That’s handy, but don’t fall for the “set it and forget it” trap. Always:
- Double-check mapped fields. Automation can mangle data if fields don’t match up.
- Sample test before bulk updates. Push a few records first and see how they look.
Remember: No automation can fix bad data. Garbage in, garbage out.
Red Flags and What to Ignore
- “Verified” ≠ Perfect. No tool is flawless. Treat verification as a filter, not gospel.
- Don’t chase every bounced email. Some will slip through. Focus on trends, not one-offs.
- Ignore vanity metrics. Number of “contacts found” means nothing if half don’t reply.
Quick Reference: What Actually Works
- Trust but verify: Use Seamless’s badges as a first pass, but spot-check anything important.
- Manual checks matter: Especially for big deals or sensitive outreach.
- Bulk verification is worth it—sometimes: Especially if your list is large or you care about sender reputation.
- Don’t be a data hoarder: Delete or skip bad data fast.
Keep It Simple (And Don’t Overthink It)
Verifying contact info in Seamless isn’t rocket science, but it does take a bit of discipline. Don’t get bogged down chasing 100% perfection—that’s impossible. Make a habit of spot-checking, run bulk verification when it counts, and don’t be afraid to toss out bad leads. Your future self will thank you for it.
Got a process that works better? Test it, tweak it, and stick with what actually saves you time. The rest is just noise.
