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.

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.
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.
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.
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.
Implementation
Copy-paste ready. Replace the API key and integrate with your existing flow.
import Mailbeam from "@mailbeam/sdk";
import { HubSpotClient } from "@hubspot/api-client";
import { subDays } from "date-fns";
const mb = new Mailbeam({ apiKey: process.env.MAILBEAM_KEY! });
const hubspot = new HubSpotClient({ accessToken: process.env.HUBSPOT_TOKEN! });
async function rehygieneContacts() {
// Fetch contacts not verified in the last 90 days
const contacts = await hubspot.crm.contacts.searchApi.doSearch({
filterGroups: [{
filters: [{
propertyName: "email_verified_at",
operator: "LT",
value: String(subDays(new Date(), 90).getTime()),
}],
}],
properties: ["email", "email_verified_at"],
limit: 5000,
});
const emails = contacts.results.map((c) => c.properties.email!);
console.log(`Re-verifying ${emails.length} contacts...`);
const job = await mb.batch.create({ emails });
const results = await job.wait();
for (const result of results) {
const props: Record<string, string> = {
mailbeam_score: String(result.score),
mailbeam_status: result.status,
email_verified_at: new Date().toISOString(),
};
if (result.status === "undeliverable") {
props.hs_email_optout = "true"; // Suppress from campaigns
}
await hubspot.crm.contacts.basicApi.update(result.email, { properties: props });
}
console.log("CRM re-hygiene complete.");
}
// Run nightly via cron

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.
