Candidate Contact Data: Checking Accuracy Before a Sourcing Campaign

Better Outreach Starts With Better Contact Data

A sourcing campaign can have strong messaging, relevant opportunities, and a carefully selected audience—and still struggle if candidate contact information is outdated. Incorrect email addresses, disconnected phone numbers, and duplicate records waste recruiter time and can create a frustrating candidate experience.

Before launching outreach, take time to review the data behind the campaign. For employers working with Redwood Technology Solutions, this preparation can support a more organized recruiting process across resume search, recruitment process outsourcing, and job advertising efforts.

Check More Than Whether a Field Is Filled In

A populated contact field is not necessarily an accurate one. An email address may contain a typo, belong to a former employer, or no longer be monitored. A phone number may have changed owners. Even a technically valid address does not establish that the person wants recruiting messages.

Start With Source and Freshness

Review where each record came from and when it was last updated. A recently submitted application provides different context from a resume stored several years ago.

Keep the original source visible whenever possible. Recruiters should be able to distinguish candidate-provided details from information obtained through resume databases or other permitted sources. Follow the source platform’s terms and your organization’s privacy and retention practices.

Separate Validation From Confirmation

Basic validation can catch formatting problems, missing digits, and obvious errors. Email verification tools may also identify potential delivery issues, but they cannot guarantee that an address belongs to the intended candidate or that a message will reach their inbox.

Treat uncertain results as uncertain. Avoid automatically replacing a candidate’s contact information with an unconfirmed match from another source.

Resolve Conflicting Details Carefully

For example, a recruiter may find an older resume with a work email and a recent application with a personal address. Review the application’s communication preferences and use the candidate’s most recent instructions rather than assuming both addresses are appropriate. Retain only the history your retention practices allow, and mark superseded details so they do not return to an active campaign.

When two records share a name but show different employers or locations, investigate before merging. A mistaken merge can attach one person’s preferences or application history to another person.

Use a Practical Pre-Campaign Checklist

Create a repeatable review process before uploading records into an outreach system:

• Standardize formatting: Normalize phone numbers, country codes, and email spacing without changing meaningful information.
• Review duplicates: Compare names, contact details, and work history before merging records; shared names alone are not enough.
• Check recent activity: Look for prior replies, delivery failures, applications, or candidate updates.
• Honor preferences: Apply opt-outs, suppression lists, and recorded communication preferences across relevant systems.
• Flag uncertain matches: Hold questionable records for review rather than sending speculative messages.
• Document changes: Record what was updated, when, and from which source.

A small, reviewed pilot can help uncover problems before a broader rollout. Monitor delivery failures and candidate feedback, then correct the underlying records rather than repeatedly retrying unsuccessful contacts.

Assign Clear Review Outcomes

Give each record an actionable status: ready for outreach, needs review, or suppressed. Identify who can resolve exceptions and who approves the final campaign upload. These simple controls help prevent an unresolved spreadsheet row from becoming an automated message.

Before launch, confirm that:

• The export reflects the latest corrections and suppression updates.
• Required source and review dates remain attached to each record.
• Held records are excluded from automated sequences.
• Someone owns delivery-failure review and candidate correction requests.

Keep Accuracy and Compliance Connected

Accurate records support consistent recruiting administration, but contact verification is not a substitute for compliance review. Limit access to candidate information, collect only what your process needs, and follow applicable requirements for outreach, privacy, and record retention.

Keep Posting Obligations Separate

For organizations with OFCCP-related obligations, candidate outreach and required job listing or posting activities serve different purposes. A verified contact list does not replace applicable listing, documentation, or recordkeeping responsibilities. Confirm requirements with your compliance team or qualified adviser.

Connect Data Quality to the Recruiting Workflow

Contact accuracy should remain an ongoing practice, not a one-time cleanup. Feed candidate corrections, opt-outs, and delivery failures back into the recruiting system so future campaigns use better information.

The same discipline helps teams coordinate resume search with Craigslist job posting, manual job posting, recruitment media buying, and broader recruitment process outsourcing. Clear source tracking makes it easier to understand where candidates entered the process and keep follow-up organized.

Track Patterns, Not Just Individual Errors

Review campaign results by source and record age. If older database records generate repeated delivery failures, pause that segment for review instead of treating each failure as an isolated issue. Keep delivery problems separate from low response rates: an unanswered message does not prove that contact information is wrong.

For job advertising, check the application path as well. A broken destination link or confusing contact field can undermine otherwise well-managed postings. Test the candidate journey before publishing and after significant changes, and make it straightforward for applicants to update their details.
