The research, source, and verify workflow top SDRs use to get emails and direct dials without bouncing.
Watch a struggling SDR and a top one work the same account, and the difference isn't effort. It's the workflow. The struggling rep guesses an email, dials the main line, and hopes. The top rep researches the person, pulls a verified email and direct dial from a database, confirms it, and moves on in half the time. Same goal, completely different result.
Here's how the best SDRs find prospect contact info: they research the right person on LinkedIn, source a verified email and direct dial from a contact database, and verify deliverability before the contact ever enters a sequence. They don't scrape, and they don't guess, because guessed emails bounce and bounces above 2% quietly wreck the whole team's deliverability. This guide lays out that exact workflow, plus the shortcuts that save hours and the mistakes that cost pipeline.
Finding prospect contact info means turning a target account into a verified, reachable decision-maker: a deliverable email and a direct dial. Top SDRs do it in three layers, research to find the right person, a database to source verified details, and verification before sending, rather than scraping profiles or guessing email patterns.
The two most common shortcuts are also the two that hurt most.
Guessing an email pattern feels efficient, but you're wrong often enough to matter. You try first.last@ when the real format is f.last@, it bounces, and that bounce tells inbox providers your list is dirty. Do it across a batch and your deliverability drops for every rep on the domain.
Scraping LinkedIn looks faster, but it risks your account, breaks whenever LinkedIn changes its pages, and usually returns an unverified guess anyway. Neither shortcut scales, and both quietly damage the thing SDRs depend on most: getting into the inbox.
Top SDRs treat contact-finding as a stack, not a single trick. Each layer does a job the others can't.
The InboundLabs SDR Sourcing Stack: finding a reachable prospect takes three layers in order. Research the right person and context on LinkedIn, source the verified email and direct dial from a contact database, then verify deliverability before the contact enters a sequence. LinkedIn tells you what to say. The database makes the person reachable. Verification protects your domain.
The quotable version: "LinkedIn is where you learn the person. A database is where you actually reach them. Don't make either do the other's job."
Before you find any email, confirm who you should be contacting. Use LinkedIn to identify the exact decision-maker, their real title, and a detail worth referencing, a recent post, a job change, a company milestone. This is where your personalization comes from. It's LinkedIn's strongest job.
Don't hunt the email on the profile. Pull it from a contact database that returns a verified work email and a verified direct dial, not a switchboard number. This is faster than guessing, safer than scraping, and it gives you both channels from one lookup so you can email and call.
Confirm the email is deliverable before it enters your cadence. Verification catches dead addresses that would bounce, keeping the team's bounce rate under 2%. It's a five-second check that protects weeks of domain reputation.
Add the verified contact to your sequence along with the personalization detail you found in step one. The research and the reachable contact travel together, so your first line is relevant and your email actually arrives.
Doing this one prospect at a time is fine for a handful of named accounts. For a real list, top SDRs invert it: they define the target role and firmographics, pull a filtered list of verified contacts in one query, then use LinkedIn only to personalize the priority accounts.
That flips the time split. Instead of spending most of the day finding contacts and a little personalizing, you spend a little sourcing and most of the day on messaging and conversations. The database does the finding; the rep does the selling.
The recurring ones to avoid:
The workflow only holds up if the sourcing layer returns accurate, reachable data. That's the layer that decides whether an SDR spends the day selling or cleaning lists.
InboundLabs is built for that layer: 280M verified contacts, verified direct dials instead of switchboard numbers, and 98% deliverability so contacts are send-ready, plus buyer intent so reps work the hottest accounts first. No annual contract, free to start. See how InboundLabs sources verified contacts instantly at inboundlabs.app.
Top SDRs don't find contact info by working harder at guessing and scraping. They run a stack: research the person on LinkedIn, source a verified email and direct dial from a database, and verify before sending. It's faster, safer, and it protects the deliverability the whole team depends on.
Set the stack up once and your reps stop reconciling bad data and start booking meetings. Try InboundLabs free and give your SDRs verified contacts at inboundlabs.app.
Top SDRs pull verified work emails from a contact database rather than guessing patterns or scraping LinkedIn. They research the right person on LinkedIn, source the verified email from a database, and verify deliverability before sending, which keeps bounce rates under the safe 2% threshold.
From a contact database that provides verified direct dials, not company switchboard numbers. A direct dial reaches the decision-maker's own phone, bypassing the receptionist. Sourcing the email and dial together from one lookup lets SDRs run email and calling from a single step.
No. Scraping can violate LinkedIn's terms and risk account suspension, breaks when LinkedIn updates its pages, and usually returns unverified guesses that bounce. Sourcing verified contacts from a database is faster, safer, and protects both your account and your sender reputation.
Seconds with a database, versus minutes per contact when guessing and verifying manually. For a list, defining your target criteria and pulling verified contacts in one query replaces hours of profile-by-profile lookups, freeing SDRs to spend time on messaging and conversations.
Because bounces are scored at the domain level. When one rep sends to guessed addresses that bounce, it signals spam behavior to inbox providers, which can route mail from every rep on that domain to spam. Verified data protects the shared reputation.
Define the target role and firmographics, pull a filtered list of verified contacts in one query, then use LinkedIn only to personalize priority accounts. This inverts the time split so reps spend most of the day selling, not sourcing.
