Email Verification for CRM Data Hygiene

CRM data decays at 30% per year. Re-verify contacts automatically and keep your sales and marketing teams working with accurate data.

Your CRM is degrading silently, every day

People change jobs, companies shut down, email addresses are abandoned. A CRM with 3-year-old contacts has lost a third of its valid emails — but the records remain, polluting every campaign and sales sequence.

30%

of CRM email addresses become invalid every year

HubSpot / industry estimate

1

Business email churn is 30% per year

Every year, roughly 30% of business email addresses become invalid. Over 3 years, a contact database that was never re-verified has lost the majority of its valid addresses.

2

Sales teams waste time on bounced outreach

SDRs working from CRM sequences with stale email addresses lose hours to bounced emails and manual data cleanup — time that could be spent on live prospects.

3

Campaign metrics become misleading

When your list contains 20% invalid addresses, open rates and click rates are artificially suppressed. Marketing decisions made on these metrics are wrong.

4

Data hygiene is a compliance requirement

Under GDPR, storing inaccurate personal data without reason may violate the accuracy principle (Article 5(1)(d)). Regular verification demonstrates diligence.

Automated re-verification on a schedule

Set up a scheduled job that pulls stale contacts from your CRM, re-verifies them with Mailbeam, and writes the results back — suppressing invalid addresses automatically.

Schedule-based re-verification

Run Mailbeam verification on contacts that haven't been verified in 90 days. Keep your CRM current on a rolling basis.

Write results back to HubSpot or Salesforce

Update contact properties with verification status, score, and last-verified timestamp. Filter and segment based on email quality.

Automatic suppression of undeliverable contacts

Move undeliverable contacts to a suppression list in HubSpot or deactivate them in Salesforce — automatically, without manual review.

Batch processing for large CRMs

The Mailbeam batch endpoint handles tens of thousands of re-verifications asynchronously. Re-hygienate your entire CRM in one job.

    if (result.status === "undeliverable") {
      props.hs_email_optout = "true"; // Suppress from campaigns
    }

    await hubspot.crm.contacts.basicApi.update(result.email, { properties: props });

Challenge

A client's HubSpot database had 85,000 contacts accumulated over 4 years. Campaign open rates had dropped to 11% — well below the industry average.

Result

After a full re-verification pass, 23,000 contacts were suppressed. Open rates recovered to 28% within two months.

Open rate 11% → 28% after suppressing 27% of list

Recommended plan

Growth

CRM hygiene typically involves larger batches run monthly or quarterly. Growth provides the batch endpoint and higher monthly limits needed for database-scale re-verification.
